The Site The West Berkeley Site (CA-Ala-307), located at the junction of Second Street and Hearst Avenue in the City of Berkeley, California, was one of the last of the great shellmounds which up to a relatively few years ago lined the eastern shore of San Francisco Bay. It had survived only because part of it was wedged tightly between two old factory buildings (P1. 1). The midden lay only a few yards from the north bank of Strawberry Creek, near the stream's entrance into San Francisco Bay. Just to the west stretched the broad tidal marsh which separated the bay shore from the wide expanse of water beyond. Much of the tidal land has long since been filled in. The original dimensions and exact limits of the shellmound could not be determined because most of it had been removed. Land formerly overspread with the accumulated aboriginal refuse now lies under paved streets, railroad tracks, factory buildings, and storage yards. The mound seems to have covered an elliptical area, conserva- tively estimated at 350 X 600 feet, with its long axis paralleling Strawberry Creek. The portion remaining measured 45 X 100 feet. Approximately one half of the northern part of this had been scraped off and crushed limestone dumped on its surface. Over the years, the limestone had become consolidated into a hard stratum, three to four feet thick. At its highest point the shellheap rose 15 feet above ground level and extended three feet below. Once it had been higher for the peak had been cut down and leveled to serve as the base for a water tank. In 1950, when the West Berkeley site was threatened with total destruction to make way for industrial expansion, the University of California Archaeological Survey undertook a large-scale excavation. Work began on May 22 and continued without interruption until September 6. During December of the same year the northern part of the mound was leveled and the midden material carried away. While this earthmoving operation was in progress a quantity of artifacts and several burials were salvaged. Finally, in the spring of 1954, the old building covering the site's northwest corner was razed and digging was done beneath the floor (Appendix V). The Geographical Setting Even though the land in the immediate vicinity has been drastically altered, it is possible to describe the natural surround- ings as they must have been when the West Berkeley midden was occupied for there is nothing to indicate a marked change in the physiographic and climate conditions. The eastern shore of San Francisco Bay is bordered by a broad sloping plain, broken here and there by isolated 2 hills or ridges. Widely separated valleys, containing small streams which normally flow at all seasons, cut across the flattish terrain in an east-west direction. The plain extends gently upward to the Berkeley Hills, a prominent range, 15 miles long and 10 miles wide, with an even crest and a steep, dissected western slope. This rather rugged hilly block, aligned northwest to southeast, is not lofty. The highest points on the main ridges are Bald Peak (1930 feet), Grizzly Peak (1769 feet), Round Top (1750 feet) and Redwood Peak (1608 feet). Streams have etched deep, narrow valleys between the hills. The climate is mild, with long dry summers and relatively warm winters. For January the average temperature falls near 49?F; for September, the warmest month, it is slightly above 63 (Hambridge 1941: 783; Dale 1959:13). Most of the 23-inch annual precipitation falls during the winter, with the greatest amount for any month usually coming in January. Snow and hail are rare and unimportant in the bay region. Two extremely significant weather factors are fog, more frequent in the summer than in the winter, and cloud cover. Since they act as a screen to reduce the amount of sunshine, the fog and clouds strongly affect the temperature, rate of evaporation, and relative humidity. The mean annual cloudiness falls between 50 and 60 percent. Climate alone might indicate just two seasons - wet and dry - but there are enough variations in the weather and changes in the plant cover and so on to give abundant evidence of four (Smith 1959:11-13; Gilliam 1962:12-61). The bay area was never heavily wooded. Much of the plain had a covering of grass, interrupted by occasional groves of Coast Live Oaks and patches of brush. Vegetation became dense only along watercourses, which are fringed with Yellow Willow, California Laurel, California Buckeye and Coast Live Oaks: Hills remained almost bare of trees except in protected canyons, but a few miles to the southeast, the Oakland Hills had extensive redwood forests, of which vestiges remain. Oaks were the outstanding trees and provided the aboriginal peoples with acorns, an important foodstuff. At the time West Berkeley was inhabited the native fauna was abundant and diversified. Of the more than two hundred different species of mammals found in California, seventy-five lived in the bay region (Berry and Berry 1959:5). Deer and Tule Elk roamed the plain and foothills and the California Grizzly was fairly common. Among the lesser species were three kinds of rabbits and a variety of squirrels, rats and mice. There was a wide range of carnivores including coyotes, bobcats, mountain lions as well as weasels, badgers, raccoons and skunks. Into the bay came several sea mammals, the once abundant Sea Otter, seals, sea lions, dolphins, and porpoises. Low marshy areas attracted a great abundance of waterfowl, both year- round dwellers and seasonal visitors. Clams, oysters, mussels and many other kinds of shellfish lived in the sand-mud flat intertidal zone and the offshore waters teemed with fish, both large and small. 3 Obviously West Berkeley was an excellent location for aboriginal settlement. The immediate neighborhood provided a plentiful and diversified supply of natural foods and the exploitation of these was fairly easy. Strawberry Creek furnished a steady, though during the summer and fall months, a meager supply of fresh water. Essential raw materials - wood, plant fiber and stone - lay near at hand. The generally mild climate contributed to the favorable situation. Previous Archaeological Investigations in the San Francisco Bay Region. The numerous shellmounds, the only conspicuous remains left by the local Indians, attracted the attention and excited the curiousity of early settlers in the bay region. As long ago as the 1850's, collections were being made of stone mortars, arrowheads, bone awls, shell beads and other objects found on their surfaces, turned up by the plow, or unearthed during roadbuilding or other construction activities. Systematic investigation of the middens did not begin, however, until the early years of the present century. The formative period saw the introduction of controlled excavation and site survey, the two essential fieldwork procedures. West Berkeley was one of the first bay shellmounds to receive scientific attention. During 1902, E.L. Furlong, working under the direction of John C. Merriam, conducted limited excavations at the site for the University of California. The 265 artifacts acquired as a result of this digging were deposited in the Museum of Anthropology but Furlong's field notes apparently did not accompany the collection. Two years later, Joseph Peterson resumed the exploration, excavating at the site's northeast corner.1 A report was prepared and filed in the Museum of Anthropology (Peterson 1904). Representatives of the Department of Anthropology continued to dig sporadically at the site. Local collectors also cut into the mound and a few of their artifacts eventually found their way into the Museum's collections. Other cultural and skeletal remains were uncovered and turned in by construction workers. The Emeryville site (CA-Ala-309), perhaps the deepest (more than 32 ft.) and certainly the most famous of the Bay middens, was also first examined at this time. Work at the mound, located about two miles south of West Berkeley, was begun in 1902 by Max Uhle. Uhle's investigations were limited in scope and the number of specimens recovered was small, but he nonetheless proposed 10 distinct strata and suggested certain cultural changes (Uhle 1907). While the Emeryville shellmound was being scraped away in 1924 to convert the area into a factory site, a considerable quantity of artifacts and 1 The exact location of these excavations could not be determined. They were probably carried on in an area now [1951] under a brick building. 4 human skeletal material was salvaged. After the removal of the upper portion of the deposit by steam shovel, controlled excavations were made by W. Egbert Schenck and L.L. Loud in the undisturbed lower levels. A final report appeared in 1926 (Schenck 1926). Schenck concluded that different groups of people from nearby interior regions lived on the mound seasonally to gather shellfish and hunt sea otter and that not all of them were identical in culture. The data, however, were regarded as too sketchy to permit an extensive reconstruc- tion of the site's cultural history. In 1906, N.C. Nelson carried on limited excavations at the Ellis Landing shellmound (CA-CCo-295), four and one-half miles north of West Berkeley in Richmond, Contra Costa County. This site covered a greater area than Emeryville but was shallower, attaining a maximum depth of 30 ft. During the removal of the deposit in the following year, Nelson collected artifacts and skeletal remains. Finally, early in 1908, he sank a shaft to the bottom in search of clues to the culture represented in the lower strata which lay below sea level. Nelson published a description of the site and its contents in 1910. Aside from certain additions to, and some changes in, artifact forms, he observed that essentially the same type of culture prevailed from the bottom of the refuse heap to the top (Nelson 1910 :-402). Of considerable importance was N.C. Nelson's detailed archaeological survey, completed in 1908. Four hundred and twenty- five shellmounds, located with few exceptions, near the open bay were recorded and mapped (Nelson 1909). Probably many middens had already disappeared without a trace; a few escaped Nelson's notice. The final investigation of this early phase of shellmound exploration came in 1915 when L.L. Loud recoveted material from two shellmounds (CA-CCo-298 and CA-CCo-300) at Stege, in the city of Richmond, while they were being destroyed. In a short report, which appeared some years later (Loud 1924), a few differences between the two shell heaps were noted. The smaller abounded in bird bones, bone implements, ash layers, and calcined shells -- materials which were almost entirely absent in the larger midden. There seems to have been a difference in stone implements as well with a higher percentage of mortars and pestles in the small site, and a greater proportion of stone net- sinkers in the larger. The variations were interpreted as being due to relative age as well as environment. Following this work there was a long interval during which other bay middens were partially excavated or materials were collected from them during the earth- moving operations but, except for brief notes on a site at San Bruno in San Mateo County (Drake 1948), no descriptions were published. It should be noted that, aside from San Bruno which lies on the west side of the bay, all sites reported upon were situated on the east shore and only a few miles apart. The search for adequate means of dating the San Francisco Bay shellmounds consumed much thought and energy during this early exploratory phase. In order to determine their approximate antiquity archaeologists consistently sought a reliable basis for calculating 5 the rate at which the refuse heaps accumulated. N.C. Nelson roughly estimated the age of the Ellis Landing midden on the basis of probable daily deposition, primarily the day-to-day accretion of shellfish remains, as 3000 to 4000 years- (Nelson 1909:345-346). Final occupation was assumed to have preceded by only a short time the discovery and occupation of the country by whites (Nelson 1910: 401). E.W. Gifford later applied a more refined quantitative technique to the study of the composition of twelve Bay mounds, including West Berkeley, Emeryville and Ellis Landing, and of three middens elsewhere in California. Age estimates were made for only the last two -- Ellis Landing (3500 years) and Emeryville (3300-3700 years) (Gifford 1916:13). Schenck calculated that the accumulation at Emeryville had taken place in a relatively short period, perhaps 1000 years or less (Schenck 1926:298). These analyses were directed toward ascertaining the time elapsed between first occupation of the shellheaps and the time of their abandonment. They were not essentially concerned with relative chronology. The pioneer investigators applied themselves primarily to the task of building up a body of data, rather than to the interpre- tation of the bay region's cultural history. Beyond the observation of slight differences between sites and minor changes of content within shellmounds, the problem of sequence or developmental change was not seriously considered. Actually the notion seems to have gradually emerged that the local prehistoric cultures remained static, or at best, changed slowly. This was due in part to the earlier explorations having been conducted without a sense of genuine scientific problem but even more to the great size of the middens and their simple and limited artifact inventory (Kroeber 1936:108). Contributing to the difficulty of reconstructing history was the small amount of carefully conducted. research. The first comprehensive effort to piece together the regions' aboriginal past and to provide a chronological framework came in 1948 when R.K. Beardsley proposed a cultural sequence for the San Francisco Bay area and the Marin County coast to the north (Beardsley 1948, 1954a, 1954b). This interpretation was based on an examination of artifacts accompanying burials from the published sites and of others not yet described in print. The technique of burial analysis had earlier been applied in the lower and middle Sacramento River Valley, where a threefold sequence of prehistoric horizons -- Early, Middle (formerly termed Transitional) and Late -- had been worked out (Lillard, Heizer and Fenenga 1939). Beardsley fitted the San Francisco Bay and Marin coast sites into the classification developed for the interior. Local variations of manifestations of Middle and Late horizons were recog- nized. The lower levels of Emeryville were assigned to the Middle period; the remainder to the Late (Phase I). Ellis Landing, Stege, and West Berkeley were ascribed to the Middle horizon. No sites of the distinctive Early culture were recognized, though the occurrence of a few specific Early cultural items was noted. It was assumed that the bay and coastal cultures equated typologically with those of the interior and placed within the same horizon were contemporary. 6 This chronological scheme is probably correct in broad outline for it seems logical to expect that something corresponding to cultural development in the interior must have taken place on the bay and coast in view of the geographical proximity and established trade relations of the two regions. It is essential, however, to realize how sketchy, from the point of view of real evidence, the associations and tie-ups and, therefore, inferences are, because classification schemes, once published, are often followed without question by other investigators or with a forcing or straining of the data. As indicated, the bay sites were assigned to the various horizons on the basis of burial associations alone. In the Emeryville shellmound, of the 700 interments recorded, 83 had grave goods and of these only 48, roughly 7 percent of the total, were utilized because the remainder lacked depth data or diagnostic artifacts. The number of burials from other shellmounds was even smaller. The assignment of sites to horizons on the basis of burial accompaniments alone probably has more validity for the interior, where 70 percent of the graves contain artifacts. The twenty years which have elapsed since the publication of Beardsley's cultural sequence have witnessed the excavation of a number of San Francisco Bay shellmounds and their placement within the suggested chronological framework. The most prolonged digging has gone on at the Patterson midden (CA-Ala-328), located about three miles south of Alvarado in Southern Alameda County (Davis and Treganza 1959). This big, productive shellheap contains materials ascribable to both the Middle and Late periods. The earliest component (Patterson facies) antedates the Middle horizon manifestation at Ellis Landing and Emeryville. The results of several field sessions, conducted for the most part between 1935 and 1959, at the Fernandez mound (CA-CCo-259) in Rodeo Valley, Contra Costa County, have been summarized (Davis 1960). Three main archaeological components, ranging from Middle through the final phase of Late horizon, were distinguished on the basis of burials and their accompaniments. Two Marin County sites have been partially explored and their contents described. Test excavations at the first, the Thomas shellmound (CA-Mrn-115) situated on the bay shore north of San Rafael, revealed that the upper portion of the refuse deposit contained artifact types diagnostic of Late times whereas the group of objects from deeper down could be fitted into the Middle period (Meighan 1953:4-5). A smaller shellheap (CA-Mrn-20) at Strawberry Point on Richardson Bay, an arm of San Francisco Bay, produced an artifact assemblage which demonstrates that the site's major occupation came in a time of transition between the Middle and Late horizons (McGeein and Mueller 1955). Of extreme importance were investigations at two localities which yielded cultural materials of greater antiquity than any previously reported for the bay region. A salvage operation carried on at University Village (CA-SMa-77), near Palo Alto in San Mateo County, resulted in the discovery of a unique series of artifacts which were assigned to an early San Francisco Bay period (Gerow 1968). 7 A second rescue effort at three sites in the interior drainage area of Contra Costa County led to the recognition of five temporal components (Frederickson 1965). The deepest habitational stratum at one of the three sites, Stone Valley (CA-CCo-308) in Alamo, yielded 93 artifacts, all compatible with the Early horizon though the burial posture differed. Archaeological work has gone on at additional shellmounds, most often while they were being leveled and their sites given up to residential or industrial developments. But aside from the descrip- tion of a deeply-buried midden near Walnut Creek (Heizer 1950) and two sites south of Alvarado (Rackerby 1967), no reports on any of these has yet appeared in print. Many more shellheaps have vanished without any record of their contents having been obtained. There have been other recent developments. Quantitative studies of the constituents of aboriginal middens have been refined (Cook 1946; Cook and Treganza 1947; Gifford 1949; Greengo 1951; Follett 1957). Quite apart from considerations of the shellmounds' antiquity, these careful analyses have furnished useful facts on the diet and eating habits of the bay region's prehistoric inhabitants. Radiocarbon determinations have provided absolute dates for several of the mounds, including Emeryville, West Berkeley, Patterson and University Village (Heizer 1959). And interpretation has not been wholly neglected. A treatise on native California settlement patterns contains a brief examination of conditions in the San Francisco Bay area (Heizer and Baumhoff 1956:37-38). Exploitative economics and culture change in Central California, including the bay region, have been scrutinized (Gould 1964) and the use of rocks and minerals by the local Indians detailed (Heizer 1951). Finally, the entire archaeological story has been popularly recounted in an imaginative manner (Suggs 1965). Such briefly, is the history of prehistoric research around the shores of San Francisco Bay. That progress has been slow and spotty is obvious. There never has been a sustained, planned program of shellmound exploration and, even though a considerable body of knowledge has gradually accumulated, no adequate conception of the region's past has been gained. The 1950 West Berkeley excavation, the results of which are described in the following pages, add concrete data and fill in at least one important gap in the archaeological record. Excavation Although the mound had already been greatly reduced in size when digging began, enough remained to give a fair sample. When the growth of weeds and litter of factory debris covering the surface had been removed, an area at the south end was staked out in five-foot squares. A cut 20-25 feet wide was then carried in along the site's major north-south axis. The material was removed with shovels in 8 arbitrary 12-inch layers until the underlying sterile stratum was reached. The excavation then was carried an additional foot down to make certain nothing was overlooked. When a trench was completed, the next five-foot section was cut down, the open trench being used as a place to deposit back dirt. The over-all plan had to be altered occasionally to avoid undermining factory walls or railroad tracks, to follow out special features, or for other reasons. In order to obtain as full information as possible, four trenches were excavated entirely with trowels instead of by the shovel method. The area excavated comprised approximately 1,175 square feet, worked down to depths of 9 to 18 feet according to the thickness of the deposit. Roughly, about 14,000 cubic feet of midden received examination. In addition to the main trench, a 10-foot square pit was cut through the overburden of limestone at the north end and carried down through the midden deposit to sterile soil. This was the section later leveled to ground surface by earth-moving equipment. Deep auger borings were made in the base of the midden at several points. These probings showed that a heavy but well-drained yellow clay extended down about 3 feet, where it merged with a damp layer consisting of clay mixed with rounded pebbles and angular fragments of sandstone. Profiles taken across the excavations at five-foot intervals showed a marked soil difference, which divided the deposit into two layers. The bottom of the mound rested upon an underlying clayey material free of artifacts and shell, a compact yellow alluvium doubtless derived by wash from the nearby hills. The undisturbed yellow soil graded upward into a darker zone, different in texture and appearance, still compacted but containing shell, charcoal, artifacts, and human and animal bones. This layer extended from the sterile base to a maximum height of about 12 feet and shaded gradually into a dark gray softer mass of shell, soil, ash, and organic matter, the more typical midden deposit, which reached to the surface. The uncompacted portion of the shellheap attained a maximum thickness of about six feet. Pockets of shell and ash were irregularly dispersed throughout but widely spread lenses were not found. The upper one to two feet consisted of a disturbed powdery layer of low artifact content. A typical section of the deposit where the layers were most clearly marked is shown in Plate 2. West Berkeley's internal structure proved to be strikingly similar to that described for the Ellis Landing shellmound (Nelson 1910:374-375). Artifacts San Francisco Bay middens characteristically yield a small quantity of artifacts, tending to furnish only about one item, whole or broken, per cubic yard dug (Kroeber 1925:25). West Berkeley proved no exception; only 3,412 man-made objects were collected, 9 including those found by Furlong, Peterson, and others. Besides prehistoric implements, the excavation yielded broken china, bottle glass, nails, and various other evidences of white occupation. Surface disturbances resulting from recent digging of supports for the water tank and from other activities displaced some of the latter to depths of 1 to 2 feet. This represents entirely a post-Indian accumulation; none appears to be "contact material" in the sense of having been obtained by the Indians from Europeans. The artifacts, while not abundant or spectacular, are fairly diverse. Their frequency is given below. Fragments are included along with whole objects.

This can be attributed, in the main, to recent disturbance, though the possibility of a more rapid build-up of the refuse cannot be overlooked. A decided decrease in numbers of articles also occurred as the bottom of the shellmound was approached. Stone Lithic artifacts form a high percentage of the West Berkeley specimens. They can be grouped initially into two main categories: objects manufactured by a chipping technique and those produced by pecking or grinding. A third minor group is made up of unworked stones and minerals presumably used by the aboriginal inhabitants or collected as curiosities. Chipped stn Except for a fair quantity of rather amorphous scrapers, chipped stone specimens were not particularly plentiful. In general, the workmanship is good though a great deal of percussion flaking is observable. The materials consist of various cherts, obsidian, basalt, slate, and a quartz-like stone. There are nearby sources for all of these (Bowen 1962) except obsidian, the closest known outcroppings of which lie in Napa, Sonoma and Lake Counties, some miles north of San Francisco Bay (Heizer and Treganza 1944:304-305). 11 Projectile_points -- Fifty-six flaked stone objects which may be termed projectile points were found. They are too large and heavy to have been used on arrows and the majority would have been most serviceable as dart tips. Four classes of points can be recognized. a. Stemmed: leaf-shaped, contracting stem -- (20 specimens, 9 obsidian, 8 chert, 3 slate). In general this is a heavy point with defined shoulders, ranging from square to sloping, formed by lateral notching (P1. 3, a-c). One has only a single shoulder but this seems to be a roughly reworked broken specimen rather than a special form. Regularly, the stems contract to a rounded tip, though in a few instances they vary toward parallel-sided. None is barbed; the edges are somewhat beveled. The points differ in size, the range being from 5 to 8.6 cm. in length, 1.8-3.3 cm. in maximum width, and 5-12 mm. in thickness. Average dimensions are: length 6.9 cm.; width 2.45 cm.; thickness 7.4 mm. Stems are relatively short, measuring 1.0-2.3 cm. with an average of 1.6 cm. The stems of two specimens retain traces of adhesive. b. Stemmed: leaf-shaped, expanding stem -- (8 specimens, 5 obsidian, 2 chert, 1 quartz-like). These weapon tips have broad U-shaped side notches and rounded bases (P1. 3 d-f). One aberrant piece has a rudimentary basal notch. The eight points are somewhat smaller than the preceding. The length range is 4.1-7 cm., average 5.4; widths very between 1.9 and 2.6 cm., with an average of 2.3 cm.; thicknesses are from 6 to 10 mm., average 8 mm. c. Stemless: leaf-shaped, convex base (8 specimens, 5 obsidian, 2 chert, 1 basalt). The greatest width of specimens of this class comes about one-fourth up from the base (P1. 3 h,&). Thence the blade tapers to a long sharp point at one end and to a blunt-pointed, sometimes almost rounded, butt at the other. Dimensions are: length 4.2-8 cm., average 5.8 cm.; width 1.8-2.3 cm., average 2.2 cm.; thickness 5-10 mm., average 8 mm. d. Stemless: leaf-shaped, concave base -- (1 specimen, obsidian). A squat missile tip has a broad and shallow basal notch (P1. 3 i). This specimen, manufactured almost entirely by the percussion method, has a deep indentation on either edge about half- way down the blade. It measures 5.3 cm. in length, 3.6 cm. in width, and is 9 mm. thick. It appears to be a retouched fragment of a large blade. e. Unclassifiable tips and median fragments. Twenty-one unclassifiable fragments were unearthed. Twenty are of obsidian and one of gray chert. Except a single specimen, unearthed at a depth of 20 inches in disturbed slough at the midden's southern border, all the projectile points were recovered below the 6 foot level. No clean-cut strati- graphic differences in classes is noticeable, though three of the four leaf-shaped, convex-based specimens for which there is depth provenience came from above the 8-foot level (Table 1). Aside from this form, which occurred at Emeryville and Ellis Landing, the West 12 Berkeley points are not duplicated in nearby shellmounds. The only examples analogous to the large-stemmed variety are two obsidian points from the deeper portion of Ellis Landing (Nelson 1910: P1. 44, Figs. 1,4). A vaguely similar but smaller specimen was obtained at Emeryville (Schenck 1926: P1. 486); its depth is unknown. In size and outline, the West Berkeley specimens show more resemblances to interior Early horizon points than to those recovered from Bay sites (Heizer 1949:20-23, Figs. 11-14). The Valley toolmakers also exhibited a preference for obsidian, the most frequently used material at West Berkeley, but often resorted to the use of stones less amenable to fine chipping. Weapon tips are more numerous in the interior settlements where they frequently accompany burials. Table 1 Projectile Points Length (cm.) Width (cm.) Depth Form No. Max. Min. Aver. Max. Min. Aver.

They are all leaf-shaped and chipped over both faces. a. Leaf-shaped, pointed base -- (6 specimens, obsidian). These large bipointed specimens are characterized by,fine, often diagonal flaking over both surfaces (P1. 3 I,k,l). Their edges have been delicately retouched, giving a neatly chipped border with shallow serrations. A lenticular cross section is basic. In size, range is from 10.1 to 14 cm. long, from 2.7 to 3.8 cm. wide, and 7 to 9 mm. thick. Average dimentions are 11. 5 cm. long, 3 cm. wide, and 8.5 mm. thick. Two of the five whole specimens were associated with burial 32; another pair, located in adjoining pits at the same level, may have been with this interment. An incomplete example was collected during filling-in operations in the same general area. Large, symmetrical implements of this kind may well have served as ceremonial objects or treasures, prized works of skilled craftsmen. b. Leaf-shaped, squared base -- (7 specimens, obsidian). These long and narrow specimens have squared bases, thinned by removing several longitudinal flakes and by grinding or polishing from each side (P1. 3 m,n,). The two whole specimens measure 9.7 cm. and 13.5 cm. in length and have maximum widths of 3.1 cm. and 3.0 cm. Each is about 10 mm. thick. The flaking is somewhat less skillfully executed than in the group described in the preceding paragraph, with numerous percussion scars visible on the surfaces. The borders are not serrated. c. Leaf-shaped, concave base -- (1 specimen, obsidian). This knife blade has a deep, rounded concavity at the base (P1. 3 o). This is more or less straight-sided, though slightly asymmetrical. Flaking is rather coarse on both surfaces. The specimen is 8.6 cm. long, 2.3 wide, and 1 cm. thick. d. Leaf-shaped, stemmed -- (2 specimens, obsidian). Some- what similar in form to the contracting stemmed projectile points though larger, are two obsidian blades. One has sloping, ill-defined shoulders (P1. 3 p); on the other the shoulders are essentially square. Their stems narrow toward a round base. The largest of the pair measures 2.7 cm. X 10.5 cm. and is 9 mm. thick; the second is about 1 cm. shorter. Their provenience is unknown. e. Leaf-shaped, notched and stemmed -- (2 specimens, chert). Two exceptional specimens made of a white chertlike material were taken from the same grave that yielded the pair of bipointed specimens (burial 32). Both have corner notches, though they are not deep on one of the examples (P1. 3 1,r) . Well-defined side notches occur on the more complete blade. Originally, both appear to have had narrow stems, probably contracting, though on one it has been broken away. The blades are broad and flat with toothed borders. The largest has an over-all length of 15 cm., is 45 cm. wide and 7 mm. thick; the other measures 4.8 X 12 cm. and is 6 mm. thick. 14 The small number of knife blades makes statements concerning their vertical distribution somewhat unreliable, but certain depth differences can be noted (Table 2). The bipointed form remained limited to the upper 44 inches of the deposit; the pair of white blades was also obtained from this level. The squared and thin-based variety occurred between 96 and 126 inches, and the single concave- based specimen for which there is depth information came from 157 inches. Two large doublepointed blades accompanied a burial at Ellis Landing (Nelson 1910:389). This is a form usually attributed to the Middle horizon (Beardsley 1948:11). The hollow-based knife found at some depth in the West Berkeley midden, is also considered a typical Middle form of the interior and coast (Heizer and Fenenga 1937:386; Lillard, Heizer, Fenenga 1939:P1. 24, Figs. 1 and 2; Beardsley 1948:11). The only specimen analogous to the white, side- notched blades, comes from a site in the Lodi region of the northern San Joaquin Valley (Schenck and Dawson 1929: P1. 91, c). However, some bearing a general resemblance have been recovered from Middle and even Late period Valley sites (Lillard, Heizer, and Fenenga 1939: P1. 24, Figs. 3,4,24,25). Chipped blades with a squared and ground base are characteristic of the interior Early horizon settlements (Heizer 1949:Fig. 11, -t). Table 2 Knife Blades Length (cm.) Width (cm.) Depth Form No. Max.

Although a few are well-formed and carefully chipped, most of them consist of flakes or cores with little or no modification beyond the sharpening of one edge. The edging was usually done from one face by the percussion method. Chert was the most frequently used raw material, with quartzite and other stones being utilized only rarely. Scrapes of obsidian or sections broken off from obsidian points or blades were occasionally made into scrapers but this material appears to have been far too precious for regular use in manufacturing these simple service tools. a. Flake (136 specimens). These comprise irregular flakes, usually fairly thick, struck off so as to give a sharp edge, which was then retouched. The tools are very diverse in form and size and could have been divided in a number of descriptive classes, with the vast majority falling into the category of "side-scrapers." But that these differences have any far-reaching significance is doubtful, since the form seems to be due to the chance shape of the flake struck off. The flake scrapers vary in length from 2.1 to 7.2 cm., averaging about 4.3 cm. Widths are from 1.4 to 6.1 cm. with an average of 2.9 cm. In thickness there is a range from an exceedingly thin specimen, only 3 mm. thick, to one 2.5 cm. The average thickness is about 1.3 cm. b. Core (58 specimens). Both thin and somewhat heavy cores were utilized in fabricating these tools. Large primary flake scars are visible on their surfaces with secondary finishing normally limited to one edge, usually about one-third of the core's periphery. On 54 examples the working edge has been produced by the intersection of somewhat irregular flutings with a flat plane surface resulting from removal of a large flake below; the remaining four lack the flat undersurface. The smallest specimen measures 2.2 X 1.5 cm. and is 1.1 cm. thick; the largest is 5.3 X 7.5 cm. with a thickness of 1.6 cm. Average dimensions are: length 5.5 cm.; width 3.8 cm.; thickness 2.0 cm. The vertical distribution of scrapers (Table 3) indicates a somewhat higher incidence in the middle and lower levels. The apparent lack of a specific standardized form makes comparison with other sites difficult and, furthermore, the data on scrapers from San Francisco Bay sites is sketchy. Uhle regarded a number of irregularly shaped tools from deeper levels at Emeryville as scrapers or choppers (Uhle 1907:65). Schenck, however, reported only two such articles but plentiful chips of chert bearing no evidence of retouching (Schenck 1926:243). No scrapers are mentioned for either the Ellis Landing or Stege sites. The seeming scarcity or, in some sites, the absence of scrapers is perhaps due to a search for a defined shape and an unwillingness to accept crude, partially chipped objects as man-made tools. 16 Table 3 Vertical Distribution of Scrapers Depth (ft.)

These implements cannot easily be distinguished from core scrapers, except that they are larger and heavier. There is no reason to doubt that, although their main function was hacking or chopping, they served also for cutting and scraping. Their shape is that of good-sized, untrimmed cores with a sharp edge formed by striking off large flakes from one side only. The tools' borders regularly show signs of battering or wear. They range in size from 15.2 cm. X 8.2 cm. to 8.3 cm. X 5.7 cm. Choppers were evenly distributed throughout the debris, occurring from the surface to a depth of 17 feet. Pecked and Ground Stone There was no dearth of articles manufactured by pecking and grinding but apart from a few ceremonial and ornamental forms, the objects are simple in nature and little care was lavished on their production. The region supplied the prehistoric inhabitants with an abundance of suitable raw materials. 17 Mortars -- Stone mortars were among the more common household implements. Materials used most frequently in their manufacture were basalt and hard sandstone; a few specimens were fashioned of meta- morphosed stones. Mortars are difficult to classify because the forms vary a great deal and many of the specimens either retain the natural shape of the rock or seem to have received their shape through being used. They can be divided into five descriptive groups. a. Semispherical (19 specimens). These fairly symmetrical mortars have convex, thick side walls. The entire outer surface is normally smoothed, though not really shaped, by pecking. The vessel lip is thin and rounded, occasionally grooved or scalloped and the inner cavity is broad, round, and fairly deep. A rounded bottom is characteristic. None is entire but it is possible to estimate the diameter of several of the 19 specimens. They show a range from 19 to 30 cm.; average cavity depth is about 13 cm. b. Oval (8 specimens). Similar to the above but made from flatter stream or beach cobbles are eight fragments of rather irregular, convex-sided mortars. Their surfaces have been only slightly modified, pecked here and there to remove irregularities. The interior consists of a shallow oval depression. Their rims are broad and rounded; their unshaped bases tend toward flatness. Three fragments were fitted together to form a vessel with a diameter of 22.6 cm. and a height of 17.6 cm. The cavity has a depth of 14.3 cm. c. Unshaped (7 specimens). Made from rounded boulders, these mortars have rough natural surfaces. The two largest specimens, found inverted over the pelves of burials, are included in this group. Each weighs well over 100 lbs. One has a diameter of 37.1 cm. and a height of 25.5 cm.; the cavity is 20.5 cm. deep. The other specimen has a diameter of 45 cm., a height of 32 cm., and a cavity 19 cm. in depth. Their grinding depressions are broad and bowl-shaped; bases are irregular; rims are modified only by use. Fragments of five smaller specimens possess estimated diameters of 15-22 cm. d. Cylindrical (4 specimens). Four sections of what appear to be deep, nearly straight-sided mortars were found. The exterior surface of each has been carefully finished. Rims are thin and well rounded. Exact dimensions could not be determined. e. Unclassifiable fragments. Twenty-six recognizable but unclassifiable mortar fragments were obtained. Several show smoke- blackening, presumably from use as firestones. "Paint" mortars -- A special group, often referred to as "ipaint" or "medicine" mortars because of their small size, is repre- sented by eight specimens. Two distinct varieties can be recognized. a. Cylindrical (5 specimens). This first group appears to have been made from broken ends of cylindrical pestles. Their sides slope slightly inward to a rounded base. The lip is rounded and thin; 18 the grinding concavity is relatively shallow. The mortars have diameters of 6.7-7.9 cm., stand 4.6-6.0 cm. high, and have cavities 2.3-2.4 cm. deep. b. Semispherical or oval (3 specimens). Three mortars have been fashioned from smooth pebbles. Their edges tend to be somewhat square; their bases have been flattened by pecking. In overall dimensions they exceed the other group, ranging from 9.2 to 11.2 cm. in diameter, from 6.7 to 7.1 in height. Cavities measure from 2.8 to 2.9 cm. Depth information on mortars, owing to omissions and errors in field recording and in museum cataloging, is too spotty to permit precise statements concerning stratigraphic differences, though a few suggestive distributions can be mentioned. The semispherical form, by far the most abundant, occurred quite generally from near the surface to the lowest level, with about the same frequency at all depths (Table 5). The cylindrical mortar fragments were all secured from below 7 feet, with two lying near the bottom of the deposit. Three "paint" mortars, for which there is depth provenience, came from between 5 and 8 feet. Table 4 Mortars Diameter (cm. ) Form No. Max. Min. Ave r.

The semispherical variety was present at Emeryville, though not numerically dominant; the oval and large unmodified forms also occurred (Schenck 1926:245-247). The commion Emeryville mortar, a large well-finished container with a flat bottom, flared sides, and beveled rim, generally considered to be a late type, was lacking at West Berkeley. Semispherical mortars were obtained at Ellis Landing (Nelson 1910:385). Miniatures were unearthed at Emeryville, Ellis Landing, and Stege (Uhle 1907:Fig. 4, 44; Nelson 1910:Pl. 42, Fig. 2; Loud 1924:364). Small mortars are regarded as a feature of the Middle horizon culture in the Delta region (Lillard, Heizer, Fenenga. 1939:78). Around San Francisco Bay, mortars and pestles appear to have consider- able antiquity, with some forms continuing in use over a long period. No convincing proof of the precedence of the milling stone over the mortar, has been found, a shift noted elsewhere in California. Except for the mention by Uhle (1907:46) of three doubtful milling stone fragments from Emeryville, and a statement that flat grinding slabs are known from Middle horizon sites around San Francisco Bay (Beardsley 1948:10), no implements of this type have been reported. Pestles -- Pestles are made from a variety of stones, all apparently of local origin. Most are of compact, fine-grained sand- stone, but igneous rocks were also used. All degrees of finish from roughly pecked or even natural surfaces to smooth and highly polished faces are evident. Ornamental specimens, decorated with rings, knobs, or flanges, are absent, however. The pestles fall into four classes. a. Cylindrical (44 specimens). Characteristically round in cross section, though at times elliptical, these pestles are carefully worked and highly polished. All are short, 10.6-12.6 cm., averaging 11.4 cm., and stout, with diameters 5.3-7.6 cm., averaging 6.07 cm. Their ends, originally flat, have become rounded through use. This was by far the most numerous type. b. Conical (13 specimens). This somewhat longer variety tapers from a broad base to a blunt point at the grasping end. The striking base is rounded and battered from wear. Like the preceding, these implements are regularly circular, or nearly so, in cross section, but less care was used in their fashioning. The longest is 16.6 cm., the shortest 13.3 cm.; diameters ranged from 6.2 to 9.1 cm. The scarcity of whole pestles makes the averages of 16.0 cm. in length and 7.5 cm. in diameter somewhat untrustworthy. c. Conical, small (9 specimens). Because of their small size and careful construction the pestles in this group are considered to have had a specialized function, such as grinding pigment. Like the conical pestles they taper to a blunt point. Both ends generally show the effect of pounding and one pestle has hematite adhering to its base. The specimens measure 11.3-12.5 cm. in length with an average of 11.9 cm.; diameters are 4.0-4.7 cm., averaging 4.2 cm. 20 d. Unmodified cobble (3 specimens). Conveniently shaped beach or stream cobbles were not regularly employed as pestles. A single complete specimen and two broken ones make up this category,. Both ends of the first, entire pestle, which measures 13.6 cm. in length and has a diameter of 8.4, appear to have been functional. Table 5 shows the stratigraphic position of pestles. Table 5 Depth Distribution of Pestles Depth (ft.)

The less numerous conical pestles had a scattered occurrence with none found about 6 feet. The others are too few to have any real significance. Apparently several forms saw contemporaneous use. The short cylinder, the prevailing West Berkeley pestle, was the most abundant form at Stege and was also well represented at Emeryville (Loud 1924:363-364; Schenck 1926:248). The conical or tapering variety, numerically the most important at Emeryville, occurred with less frequency at Stege. Crude cobbles were utilized at both sites and paint pestles are reported for Stege. Few details on the Ellis Landing specimens are given (Nelson 1910). 21 Net sinkers -- The most numerous objects from West Berkeley consist of notched or grooved stones, 360 of which were obtained. They comprise ordinary beach or stream pebbles, unworked except for notches or grooves pecked into them at or near their centers. Presumably the stones were tied to fishing nets to weight them down. Smooth and rounded sandstone pebbles were generally selected, though the shellmound people occasionally used irregular stones. Two types, notched and grooved, can be distinguished. The two varieties inter- grade and apparently were used simultaneously, since they were found at the same levels and occurred together in caches. Four caches of 42, 9, 7 and 3 sinkers were uncovered. The largest of the caches also contained a pestle and several mortar fragments. a. Notched (211 specimens). These are flattish stones, more or less oval in outline, notched at opposite corners to keep an encircling line from slipping. In weight they range from 2 to 15 oz., averaging about 7 to 8 oz. This was the most abundant form. b. Grooved (149 specimens). More rounded or spherical stones were selected for this group of sinkers, each of which was slightly grooved transversely. Rarely, a small pestle was girdled. Their weight varies from 5 to 16 oz. with an average slightly above 8 oz. A tabulation of the vertical distribution of 253 of these objects indicates their absence or extreme rarity in the upper nine feet of the refuse with greatest relative frequency between 10 and 15 feet. There was a gradual decline in numbers toward the bottom of the deposit. Net Distribution of Net Sinkers Depth (ft.)

This suggests that these large food fishes were the ones taken in nets weighted down by notched and grooved stones. Bony elements attributable to the two species gradually diminish, like the net sinkers, in the upper levels of the midden. Stone sinkers have been reported for several San Francisco Bay mounds. The larger Stege shellheap yielded many specimens; the smaller one, fewer (Loud 1924:362). At Ellis Landing a fair number were recovered from the upper 4-5 feet of the deposit, but sinkers were absent in the middle levels. When excavation was carried below the waterline, they appeared again and continued to the bottom (Nelson 1910:387). Only one specimen, a grooved sandstone pebble, was recovered at Emeryville (Schenck 1926:264), but this object may well have been picked up elsewhere. The variation in relative frequency of this type of artifact in Bay mounds has been noted several times. Sites where sinkers occurred in abundance were regarded as unusually favorable spots for fishing. Loud, however, suggested the possibility of cultural and, presumably, temporal variation in the sinkers' presence (Loud 1924:363), an assumption which seems to be correct. On the Marin seacoast notched and grooved stones are common in sites attributed to the Middle horizon (Beardsley 1948:12), but it is reported that they were used little, if at all, in the later times. Sacramento Valley sites generally lack stone sinkers but they seem to occur in Late horizon (Phase I) times. Anchors (?) -- Two grooved stones, weighing 2 lbs., 9 oz. and 6 lbs., 3 oz., are seemingly too large to have served as net sinkers and can probably be considered boat anchors. The first has a longitudinal groove; on the second, the rough groove is transverse to the stone's long axis. A large girdled stone also came from one of the Stege mounds (Loud 1924:363). Chisel -- A chisel or wedge-shaped object of sandstone shows a working which was beveled by pecking and grinding from both sides. The tool's butt end is flat and scarred. Its dimensions are 3.1 by 11.5 cm. Ornaments -- Stone objects for personal adornment were uncommon at West Berkeley. There are several distinct types. a. Pendants. Three thin, oval pendants, made from grayish- green steatite, were found at the neck of Burial 71, 112 inches from the surface. The pendants' upper and lower borders are deeply, and apparently ornamentally, notched. Each specimen bears a single perforation, drilled, from both faces, near one end. The pieces range in size from 1.5 to 1.8 cm. and are 2 mm. thick. A similar, though 23 incomplete, specimen was found at Ellis Landing (Nelson 1910:399, P1. 45, Fig. 4). From the West Berkeley site also came a flat, rectangu- lar pendant of darker steatite, drilled close to one end. The base of this specimen is missing so its complete length cannot be deter- mined. Somewhat similar but tapering toward the base is another fragmentary pendant of hard white stone. This is elliptical and thin near the upper drilled end and rounded toward the base. b. Ring -- A ring-shaped ornament of grayish-green steatite, 3.1 cm. in diameter, came from the ear region of burial 70, 85 inches beneath the surface of the mound. A spot of asphalt on the rim retains an impression of a thin, 2-ply cord. The article is too small for a bracelet and too large for a finger ring. It had been placed with the burial in such a way as to suggest that it hung suspended from the ear lobe by a string. Ring-shaped ornaments are common in Middle horizon sites in the Delta region. c. Ear Plugs -- Two smoothly-worked objects of fine-grained sandstone were recovered, one on the surface, the other 35 inches below. They are almost cylindrical in form, having only slightly different diameters at opposite ends. Their bases are squarely cut and one is pitted in the middle. This latter specimen also has a shallow encircling groove near its center. The largest of the two measures 2.2 cm. in length and one end has a diameter of 2.5-2.7 cm., the other end a diameter of 2.7-2.8 cm. The dimensions of the second are: length, 1.7 cm., diameters 1.8-2.0 and 2.1-2.3 cm. The purpose of the objects is not clear though it has been suggested that they were worn as labrets or as earplugs (Uhle 1907: 59-60). Similar objects were found at Ellis Landing (Nelson 1910:390), and three were recovered at Emeryville (Schenck 1926:253-254). They are generally made of local sandstone. A special feature of the Sacramento Middle horizon culture, south of Carquinez Strait, is the occurrence of steatite labrets and earplugs like the sandstone specimens from San Francisco Bay sites (Lillard, Heizer, and Fenenga 1939:78). Bars. This designation covers a miscellaneous group of elongated ground stone objects, none of which is perforated. Two long, narrow rectangles of green serpentine, well smoothed and polished, were found at depths of 88 and 100 inches. The largest is 11.3 cm. long, 1.5 cm. wide, and 6 mm. thick; the smaller measures 8.7 by 0.6 cm., with a thickness of about 1.3 cm. A short bipointed rod of brown serpentine is elliptical in cross section with one end highly polished and the other scarred with a series of longitudinal grooves. This object is 5.1 cm. long, 8 cm. wide, and 5 mm. thick. The specimens may be related to the cylindrical "pencils" or rods of the lower Sacramento region. Charmstones. The "charmstones" of California archaeology are well represented. These problematic objects, made by pecking and grinding, range from simple flattish ovals to elaborate "phallic" forms. Most of them are highly polished and symmetrical but a few are rudely shaped. A wide variety of materials, from relatively soft steatite to hard igneous rock, were utilized in their manufacture. 24 All of the materials seem to be of local origin, obtainable within a radius of a few miles from the settlement. Thirty-eight charmstones have a biconically drilled hole near one end. Often the pierced end is also notched or roughened by pecking, presumably to allow for a firmer attachment of a suspension cord. a. Oval (28 specimens). The most abundant group is essentially alike in their general oval outline but differ in details (P1. 4, a-d). In cross section the 16 completed specimens range from flattened lenticular to almost circular. There is some variation in size, though this is not great. The longest specimen is 12.1 cm. long; the shortest 6.0 cm.; the average length for the group is 8.6 cm. Diameters vary from 3.1 to 4.6 cm., the average falling near 3.8 cm. The perforation is drilled 1.5-2 cm. from one end. The majority have been made from blue amphibolite schist. One unique green micaceous schist specimen has incised grooves or scratches running diagonally around its body. Twelve unfinished charmstones have rougher surfaces with beginnings of perforations visible as small pits on one or both sides. Why these objects were not completed remains conjectural; only one seems to have been broken in process of manufac- ture. b. Biconical (3 specimens). The three charmstones making up this group are round in cross section, tapering toward each end (P1. 4, i,n). A large hole is drilled biconically 2.3-3.2 cm. from one tip. The largest complete example is 13.8 cm. long and has a diameter of 2.9 cm.; the other whole one measures 13.3 cm. by 3.2 cm. Two, including the fragmentary specimen, are fine-grained sandstone; the third is a greenish granular schist. c. Biconical miniature (2 specimens). Like the preceding, these two objects have their greatest diameter at about the center and taper toward each end (P1. 4, i,k). They are, however, much smaller and squatter, measuring 4.1 and 3.9 cm. in length; diameters are 1.6 and 2.1 cm. Soft yellow-gray steatite and green schist were used in their manufacture. d. Trianguloid (1 specimen). A pendantlike charmstone of gray steatite has a flat broad base which tapers to a squared tip (P1. 4, im). It is drilled 1.3 from the smaller end and a groove runs across the top. Square olivella beads have been affixed with asphaltum to one face. The article has a length of 6 cm.; its greatest width is 1.9 cm. e. Phallic (4 specimens). Four charmstones are easily recognizable as pahlli, though differing in size and details of construction. A double-ended green, micaceous schist specimen, 7.1 cm. long and 3.9 wide, has a large perforation in the expanded central portion (P1. 4, _). A second, of hard green stone, is cylindrical, with a perforation and groove near one end (P1. 4, h). The other two are incomplete (P1. 4, f,l). One is a highly polished portion of 25 a rather small charmstone, broken at the perforation; the other consists only of the sculptured tip. A small, heterogeneous group of eight unperforated charmstones was recovered. A considerable proportion of them reveal traces of asphalt at the upper end and a few still show marks of twisted cord, which was wound about the stone and held fast by the sticky adhesive. a. Spheroid, flat base (1 specimen). A globular specimen of hard igneous material has a flattened base and a narrow ungrooved stem which flares slightly toward a squared tip (P1. 4, r). The entire stem is coated with asphalt, though no cord impressions remain visible. Its length is 8 cm., its diameter 3.9 cm. The tip is 1.5 cm. long. b. Spheroid, rounded base (1 specimen). This rather crude charmstone has an elongated and rounded stem smeared with asphalt (P1. 4, a). The stem is not grooved but cord markings are present in the adhesive. Made from a green granular schist, it is 4.6 cm. long and has a diameter of 3.4 cm. The stem measures 2 cm. c. Plummet (2 specimens). Manufactured from a heavy green stone, the first of two plummet-shaped specimens is the most symmetri- cal of all the charmstones (P1. 4, o). Its greatest diameter, 3.5 cm., occurs below the center; thence it tapers to a pointed base. The upper portion narrows to a flattened tip, which has an encircling groove 1.2 cm. from the end. Asphalt, extending from the groove to the top, is impressed with 20 rows of fine cord and a few grains of hematite adhere to the adhesive. The second specimen has a similar outline but is less symmetrical (P1. 4, p). It has two grooves near the apex; a deep notch over the tip is filled with a mixture of asphalt and cordage. Soft gray steatite was the material selected for the fabrication of this specimen. It has a length of 7.8 cm. and a diameter of 3 cm. d. Miscellaneous fragments: Four tapering tips are round in cross section. One is grooved. The vertical distribution of charmstones in the midden indicates a clear-cut stratigraphic difference. The undrilled specimens ran from near the surface to a depth of seven feet whereas perforated examples, except for one recovered at four feet in disturbed slough, remained restricted to the lower levels, 7 to 16 feet below the surface. This distribution, demonstrating the temporal priority of perforated charmstones, agrees with the evidence obtained from other Central California sites. These distinctive prehistoric artifacts were present in other San Francisco Bay shellmounds. More than 70, all apparently from the upper layer, were obtained at Ellis Landing; 42 from the larger Stege mound, and 40 at Emeryville (Nelson 1910:388; Loud 1924:365-366; Schenck 1926:254-264). Four oval specimens from Emeryville's deepest levels were drilled and notched. Perforated stones also 26 occurred at Ellis Landing and Stege but their depth is not reported. Charmstones are numerous in lower Sacramento Valley sites where they remained important ceremonial objects from Early to Late horizon times. Early charmstones, often of phallus form, almost invariably have been bored through near one end, whereas most examples from the later cultures are not drilled (Heizer and Fenenga 1939:385-386). Certain of the West Berkeley perforated stones are identical or very similar to those obtained from Early horizon settlements. The undrilled Bay specimens resemble Middle horizon forms (Heizer 1949: Fig. 7-10; Lillard, Heizer, and Fenenga 1939:Pl. 14, Figs. d-f). Charmstones often come from graves into the interior, while around San Francisco Bay they generally turn up in the refuse without association. Unworked or Slightly Modified Stone Many additional stone items were recovered, all of them natural forms modified only by use, if at all. Hammerstones (52 specimens). Twenty-nine of the hammers consist of smooth unworked beach or stream pebbles with one or more battered edges. Hard sandstone and basalt pebbles, which do not fracture easily, were principally used. Twenty-three angular specimens of chert or similar materials have been scarred on all surfaces. A more modified series of 32 oval and discoidal stones, all of compact sandstone, were employed for striking. Some have the shape of a short, flattened pestle. A few show slight workmanship in the form of deliberate pecking along one or two edges, presumably to give a more rounded or symmetrical outline. Marks of use as a percussion instrument are visible on one or two edges. Hammerstones were evenly distributed in the mound from near the surface to 18 feet. Abrading stones -- Pieces of stone used to fashion, sharpen, or polish other objects, were not numerous. A single "awl-sharpener" has several long shallow grooves on both surfaces. Presumably abraders of whetstones are a soft fine-grained section of sandstone, scratched on one side, and a micaceous schist pebble with an extremely smooth and slightly concave surface. Several irregular fragments of sandstone with worn and flattened faces appear to be portions of polishing or grinding instruments. Anvil -- A flat slab of sandstone, 18.8 cm. long, 17.7 cm. wide, and 3.3 cm. thick may have functioned as an anvil. It has a small pit near the center of one surface but is otherwise unmodified. Slingstones (?) -- Four caches of semispherical or oval pebbles contained 17, 15, 8 and 3 specimens. Three isolated pebbles were also collected. All are of the same material, a grayish, hard sandstone, and of approximately the same size and weight. The size range is from 4.6 to 6.7 cm. with diameters of 3.7 to 4.2 cm. In weight they vary from 1-3/4 to 4-1/4 oz. with an average of a little over 3 oz. Most were quite clean, only a few showing traces of 27 fire-blackening. They are not too heavy to have served as slingstones and their general form suggests such usage. A few are battered on one or both ends, perhaps indicating secondary employment as pecking tools. Quartz crystals -- Among the most interesting unworked stone objects are quartz crystals, 16 complete specimens of which were found. All are small, the largest being 6.7 cm. long, and none reveals any modification, though one has been burned and melted. It is well known that the quartz crystal played a prominent part in the magico- religious life of the recent California Indians and their presence here suggests that it occupied an analogous position in the prehistoric period. Small quartz crystals were obtainable in Alameda County, south of the present city of Livermore, and elsewhere in the Bay region (Bowen 1962:13). Prismatic obsidian splinters -- Three slender, obsidian prisms of natural origin were found in a cache at a depth of 150 inches along with 2 stemmed points and 11 quartz crystals, an agate pebble, and a mass of powdered hematite. This association suggests a medicine bag or fetish bundle. One prism has been retouched so that it is leaf-shaped and bipointed, with a diamond cross section. The other two exhibit dull surfaces, produced by burning. Two including the reworked specimen, are 7.2 cm. long, the third measures one cm. shorter. Prismatic obsidian splinters, sometimes referred to as "tinklers" or "bangles.," are regarded as typical of the Coastal Province in Middle horizon times, where they are sometimes found in large numbers near the skulls of burials (Beardsley 1948:13). Triangular pieces of obsidian, the facets of several of which appeared to be ground smooth, where reported from Ellis Landing (Nelson 1910:289). They are absent from the Interior Province during the Middle horizon times, although they occur in both the Early and Late periods. The recent California Indians attached obsidian prisms to dance skirts. Miscellaneous minerals -- The West Berkeley collection contains a number of rock and mineral specimens, presumably picked up because of their attractive color or peculiar form. Included are several iris agate nodules, which could have been secured from rock outcrops in the Berkeley Hills, irregular pieces of quartz, an opal geode and a quartz geode broken open to get at the quartz crystals contained in it, and a small stony meteorite. Unworked brightly-colored stream pebbles were commonly met with in the refuse. All of these items were picked up and carried to the site by the Indians and perhaps retained merely as curiosities though their employment in some magical or religious rite cannot be entirely ruled out. Pigments -- Three kinds of pigment -- hematite, limonite, and a peculiar white substance, possibly diatomaceous earth -- are repre- sented. In color, the former ranges from a brownish-red to a rich, dark red hue. Powdered hematite was found sprinkled over burials and isolated patches of it also occurred. Four lumps or balls, probably remains of prepared cakes of paint material, were found. 28 The closest source of hematite lies in the Oakland hills, only a few miles away (Wallace 1947:272). Yellow-brown limonite is less abundant with four irregular lumps and a scattering over one burial. Several chunks of raw ore containing hematite and/or limonite were noted. There is one large (4 X 6 cm.) piece of a chalky substance that may have been the source of white paint. Apparently it was molded into a lump while damp, for finger marks are still visible on its surface. Bone The West Berkeley site was well supplied with bone artifacts. This material was used generously in the production of utilitarian objects, less frequently, for ornamental and ceremonial items. Awls -- A rather general category of single-pointed imple- ments, are clearly predominant among the bone articles. Not a partic- ularly well-made lot, they generally show high polish from use and some give evidence of constant resharpening of their points. Frag- mentary specimens have become frequently calcined or otherwise damaged by fire and many were recovered from ash deposits. Awls can be separated into five groups. a. Deer or elk cannon bone, split head (26 specimens). These flat, rather heavy bone awls were by far the most common. The proximal or distal end of the bone was split at the division of the articular surface and in some the end was partly worked down or ground almost flat. The shaft, which often shows the characteristic cannon bone channel, was tapered to a sharp point. The awls range in size from 10.6 to 18.4 cm. b. Deer or elk tibia, split head (4 specimens). Though the tibia bone is well adapted for making awls, it seems to have been rarely used. The four tibia awls are slightly bowed owing to the natural curvature of the bone. They possess long and rounded tips and their butt ends remain unmodified except for the original cutting. The specimens vary in length from 13.1 to 17.2 cm. c. Carnivore ulna, head intact (6 specimens). Awls made from carnivore bones all seem to be fashioned from coyote ulnae. Practically all that was done to make serviceable implements was to sharpen one end of the bone. The length range is 10. 8 to 15.5 cm. d. Mammal leg, bone splinters (14 specimens). This group includes a miscellaneous assortment of pointed tools with a rough angular appearance. They show little modification save for their smooth tapering points, and part of this may have resulted from wear. The butt ends are irregular. It is impossible to identify the bones utilized in making these tools as all distinguishing marks have been broken or cut away. Most appear to be fragments of deer or elk long bones, with an occasional piece made from a rib. The specimens very greatly in size, the shortest being 3.8 cm. long and the largest, 10.4 cm. 29 e. Bird bone, midshafts (6 specimens). These awls were made by removing the end of a bird bone and splitting the shaft obliquely, then grinding the tapering end to a point. Apparently both wing and leg bones of large marine species were utilized, though this is not certain since all identifying characters have been removed. The bird bones are rather small, 5.4 to 9.5 cm. long, and fragile. They may have served as clothing or hair pins rather than as piercing tools. f. Unclassifiable tips and medial fragments. Forty-two remnants of mammal-bone awls were recovered. All show smoothed and polished surfaces. In addition to purposefully shaped implements a number of naturally pointed bones could have been employed as awls or perforators. Ten deer splints (vestigial outer metatarsals) show signs of use and/or sharpening. Four have perforations at the distal end; four are not drilled; two are too fragmentary for determining their original condition. Sting ray spines with the barbs worn or ground off probably saw service as piercing tools. A number of unmodified barbs were also found. The distribution of awls through the midden was quite uniform (Table 6) and the forms recovered are well represented in nearby shellmounds (Gifford 1940:161). Split-headed cannon bone awls proved the most numerous at Emeryville and Ellis Landing; tibia and splinter tools were also present in fair numbers (Schenck 1926:214-217; Nelson 1910:392). Awls are rare in Early horizon settlements of the Sacramnto Valley with fortuitous splinters, split tibiae, and specimens fashioned from coyote ulnae reported (Heizer 1949a:26). In the later Valley cultures bone awls become abundant and diversified. Table 6 Bone Awls Form Number Length (range) (cm.) Depth (in.) Cannon bone, split head 26 10.6 - 18.4 48-169 Tibia, split head 4 13.1 - 17.2 60-170 Ulna, head intact 6 10.8 - 15.5 52-173 Splinter 14 3.8 - 10 52-194 Bird Bone 6 5.4 - 9.8 120-178 Unclassifiable fragments 42 --- 12-174 Total 98 30 Flakers -- Next in numerical importance among the bone artifacts are flaking implements with their working ends rounded and irregularly scarred. Some may have functioned as gouges or punches rather than as flakers and many originally seem to have been awls put to secondary use after their points had become dulled or broken. Both land mammal and sea mammal bones were used in the fabrication of these tools. a. Deer or elk cannon bone, head intact (5 specimens). The complete distal or proximal end of the cannon bone was retained to serve as a handle on each of the five implements. All are relatively rough with little surface finish. They range in length from a short, stubby 6.5 cm. specimen to a long-bladed one, measuring 14.2 cm. b. Deer or elk cannon bone, split head (5 specimens). These are identical in form to awls made from the same bone except for the tip, which is blunt rather than pointed. Their shafts are not so well shaped or polished as those of the awls, however, which gives them a cruder appearance. The shortest is 10.8 cm., the longest 14.0 cm. c. Deer or elk ulnae, head intact (4 specimens). Ulna flakers, found so frequently in archaeological deposits throughout California, are represented by four examples. The head of the deer or elk bone remains entire, apparently to function as a handle. A single carnivore ulna was similarly fabricated. The tools are short, 9.2 to 12 cm., sturdy, and the tip, as is common in implements of this type, is well worn. d. Sea mammal tibiae, head intact (2 specimens). The distal ends of two sea otter tibiae have been fashioned into flakers. The bones were employed without splitting the head; only the shaft was cut or broken to form the working end. The flakers are relatively short, measuring 8.4 to 9.3 cm. e. Sea mammal penis bones (3 specimens). To judge from their scarred tips, three sea otter penis bones saw use as flaking tools. The bones are otherwise unmodified. They measure from 1.1 to 13.4 cm. in length. One has a coating of asphaltum on the proximal half. f. Mammal leg bone splinters (26 specimens). Split fragments of mammal leg bones were fashioned into short (5.7 to 9.3 cm.), relatively sturdy flakers. All appear crude with the butt end rough and unfinished. A few of the 26 specimens may be tips of larger specimens rather than complete tools. g. Mammal rib sections (3 specimens). On each of these tools, the rib was cut obliquely to make a beveled working edge. The butt is broken away. All may have been made from sea mammal ribs. Complete lengths could not be determined. 31 Flaking tools were present in the deposit from the surface to a depth of 14 feet 1 inch (Table 7). No obvious stratigraphic separation between the various classes can be detected. Specimens fabricated from sea mammal tibiae were limited to the upper 7 feet but there were only two of them, far too few for their occurrence to be really important. Mammal leg bone splinters with rounded scarred tips all came from near the surface. Rib flakers were represented in the three to eight and a half-foot section of the deposit, but again there are not many. Ulna tools with heads intact, two of which have specific depth data, are reported from 11 feet and 13 feet 8 inches. Table 7 Bone Flakers Form No. Length Range (cm.) Depth (in.)

Implements fashioned from sea mammal tibiae are less abundant but have been reported for Emeryville and one of the Stege mounds. Utilized penis bones were obtained at Ellis Landing and Sausalito (CA-Mrn-3) in Marin County. A single specimen manufactured from a rib is reported for the Sausalito mound. These tools appear to be rare in the delta region. Spatulas (17 specimens). Formed by splitting large bones of deer or other large mammals and grinding them flat, these broad objects have rounded ends (P1. 5, n,p). Their edges are somewhat beveled and their butt ends squared. Carefully shaped and highly polished, the articles show no signs of rough usage and to what purpose they may have been put remains unknown. They have been referred to as strigils or sweat-scrapers. Eleven were recovered from the lower levels of the mound at depths varying from 10 feet 5 inches to 15 feet 8 inches. The largest is 2.1 cm. wide and 16.9 cm. long; the smallest measures 1.9 by 11.8 cm. Six other spatula-like implements differ only slightly from flakers in having broad, rounded points. Split cannon bones were used in their manufacture. Two retain half of the distal head; the other four represent shaft fragments. The tools have not been carefully shaped, and polishing is visible only near the rounded tips. Their appearance suggests that they represent service implements. Lengths vary from 9.2 to 11.4 cm. Three of the artifacts were unearthed in the disturbed material at the south end of the midden; the remaining ones were found at depths of 9 feet to 13 feet 4 inches. Daggers (?). Allied in form and manufacture to the nicely- worked spatulas are two highly polished triangular objects made from leg bones of large mammals (P1. 5, m,o). The blade of each has been carefully worked down to terminate in a sharp point. The base, from which have been ground off all the protuberances of the condyles, is squared. The objects could have functioned as efficient daggers. The first, found at a depth of 2 feet 6 inches is 13.8 cm. long and 2.0 cm. wide; the length of the second, part of the butt end of which is missing, is estimated as 20 cm.; the width is 3 cm. at its widest point. This specimen was obtained 5 feet 10 inches below the surface. Notched scapulae (15 specimens). A characteristic, though problematical, implement is made from the thick portion of the shoulder blade of a deer or elk. One side is notched every 3-4 cm. to present a toothed and sawlike edge (P1. 5, a,b). The teeth are generally rounded rather than pointed. One unique specimen has two indented edges. The unmodified proximal end apparently served as a handle. Most of the scapulae tools are carefully fashioned and the high polish on their serrated blades indicates long use. On several, the teeth are almost completely worn down; two specimens appear to have been renotched after extended wear or when the teeth were broken out. Eight of the 15 were fabricated from right scapulae; 33 the remaining 7 are from the left. Exact dimensions are difficult to ascertain because none survives. They seem to have averaged between 20 and 22 cm. in length and 3 to 5 cm. in width. Although implements of this kind have often been referred to as "scapula saws," it is generally agreed that they are much too fragile to have been used in sawing through wood or bone. No satisfactory explanation of their function has been arrived at, though they have been variously described as weaving tools, fleshers, bark-shredders, wood-scrapers and musical rasps (Gifford 1940:172). Conceivably, they performed several tasks, including the scaling of fish or even as sickles in harvesting wild grasses. Either of the last operations could have produced the characteristic high polish on the blade. Notched scapulae were spread in the mound from near the surface to 15 feet 5 inches below. These distinctive tools seem to be especially characteristic of the San Francisco Bay region. Forty-five were taken from Emeryville; a fair number were recovered in the Ellis Landing midden, from two sites near Newark (CA-Ala-328, CA-Ala-329), and at the Ponce (CA-SCl-l) shellmound (Gifford 1940:178). Only a few notched scapulae have been reported from the delta region. Notched ribs -- Two large rib fragments, probably elk, are notched (P1. 5, c). One has large circular cuts giving a scalloped edge; the second has almost square indentations. Their original lengths could not be ascertained; their widths are 2.6 cm. and 2.8 cm. Both form and function remain uncertain, though presumably they could have served the same purpose as the serrate scapulae. Such implements are rare in Central California. A lone specimen were obtained at Emeryville, another at Newark (CA-Ala-329) and a third from Ponce (Gifford 1940:172). Single-piece curved fishhook -- A bone fishhook was found at a depth of 16 feet. It is subrectangular and has a small knob worked on the end to serve as an aid in attaching it to a line. The point is thin and delicate. The hook is quite small, measuring 2.1 cm. long and 1.1 cm. wide. Another almost identical specimen was recovered from Blossom (CA-SJo-68), an Early horizon settlement, in the lower Sacramento Valley (Heizer 1949b:192). None has previously been reported for a San Francisco Bay shellmound. Split-mammal-bone tools -- Included here is a heterogeneous lot of rough bone implements. They consist of scraps of split long bones of large mammals, most of them pressure-flaked along one or more edges. Varied forms such as would result from the chance splitting of large bones are included. Thirty-two pieces are roughly flaked along one edge to give a sharp, though irregular, cutting blade. A single specimen has flake scars on two borders. The tools' lengths vary from 6 to 16 cm. A second group of 12 bones have broad, rounded tips, some of which have been flaked. Several are highly polished, evidently through use. They are 5 to 15 cm. long and 2.4 cm. wide. 34 Sixteen additional specimens, 10 to 21 cm. long, have blunt, flaked points. Four retain the head of the bone or part of it. It is doubtful that these constitute standardized implements. Rather, they seem to be hastily improvised tools. Their relative abundance is of some interest, and they appear to have been used throughout the period of occupation. Similar rough bone objects were recovered from the lower strata of the Emeryville shellheap (Uhle 1907: 71-72). No great number of them has been reported for other bay sites. It seems probable that crude pieces like these often go unnoticed or unrecorded. Mammal rib tools -- Eleven bone pieces, all fragmentary, are somewhat curved, and appear to have been formed from mammal ribs. They are rounded, smooth points and are unusually well-polished. Their bases are missing. In the mound they occurred from 2 inches to 13-14 feet. Items of quite similar form have been noted at Emeryville and in Early horizon Valley settlements (Schenck 1926: 216; Heizer 1949a:27). Whalebone containers -- Three bowls have been hollowed from whale vertebrae. The largest (24 cm. in diameter) and most elaborate exhibits an elliptical hole (12 cm. in diameter) worked into its upper surface (figured as type BBl in Gifford 1940:225). The cavity, which tapers toward the bottom, is lined with a thin coating of a black material, presumably asphaltum. The projections of the vertebra have been removed, broken or cut off. A second container, 22 cm. in diameter, has a shallow (1 cm. deep) depression worked into one surface. The rim is ground flat. A third whale vertebra, slightly pecked on one surface, probably represents an unfinished bowl. The three West Berkeley whale bone bowl specimens are the only ones reported from Central California. Bone pins -- Seven long, nicely finished bone objects, flattened oval in cross section, may have served as hair or nose ornaments or perhaps for holding garments together. They are broken, so their exact form could not be ascertained, but all seem to be fragments of slender bipointed pins, tapering gradually and evenly to either end. Two have slightly curved or upturned points. Estimated lengths are 20 to 25 cm.; each is about 8 mm. in diameter. Four other pins were recovered from graves, two with burial 20, 5 feet 3 inches below ground level, and another pair from the grave of burial 56 at the depth of 7 feet 6 inches. The only other specimen for which provenience is recorded was found 6 feet down. Though the incomplete nature of the specimens makes comparison uncertain, it is probable that their original form was like that of the bipointed pins found in other Central California sites (Gifford 1940:176-177). Bone needles (?) -- Three small, thin, well polished splinters of mammal bone are ground sharp at one end and to a blunt point at the other. The term "needle" is applied with some doubt, since none is perforated. They all may be pins. The specimens are 9.4 to 12 cm. long. 35 Bone pendants -- Four bone pendants are thin and flat, with rounded sides that taper to square-cut bases. (A West Berkeley speci- men is illustrated as type Ql by Gifford 1940:218.) Each has a biconically drilled suspension hole near one end. Three of the four were taken from a grave at a depth of 10 feet; for the remaining specimen, the vertical position is unknown. The specimens are 1.1 to 12. cm. long, 7-8 mm. wide, and 1-2 mm. thick. Bone pendants are not numerous in Central California, perhaps because of the great emphasis upon the wearing of shell ornaments. Mammal bone bead -- A tubular bead, with roughly squared and ground ends, is cut from a small mammal bone. Owing to the bone's natural curvature, the object is somewhat bowed. A slight polish is visible on all surfaces. The bead has a length of 4 cm. and a diameter of 6 mm. Bird bone beads and tubes -- Three polished tubular objects are made from shafts of bird long bones. The process of their manufacture has removed all means of identification of the kind of bird from which they were taken. The smaller samples undoubtedly represent bone beads. They were made from small leg bones, 6 to 7 mm. in diameter, cut into lengths of 1.7 to 2.2 cm. On most examples the cut edges of the bone have been rounded and smoothed off. None is engraved or otherwise decorated. The three specimens were found at depths of 93, 95 and 132 inches. Longer tubes, fashioned in a similar manner, are highly polished, as if much handled. It seems quite possible that they functioned as drinking tubes at various life crises. One complete specimen, 10.5 cm. long and 7 mm. in diameter, and two broken ones were recovered at depths ranging from 62 to 72 inches. A cruder, less finished tube may be an unfinished product. A cache of about 20 large bird bones with their ends removed was uncovered 59 inches down in the refuse. These probably constitute "blanks" designed to be made into beads, tubes, or whistles. Undecorated bird bone beads or tubes were more abundant in other San Francisco Bay sites than at West Berkeley. Emeryville produced 87 and Ellis Landing 33. Articles of this sort are found in both coast and interior sites throughout the entire span of prehistoric time. Though rare in the Valley Early horizon sites, they occur in respectable numbers in later settlements (Gifford 1940: 179; Heizer 1949a:26). Bird bone whistles -- Slender long bones of birds were some- times made into whistles. The interior of the shaft was cleaned out and a roughly rectangular or eliptical hole was cut about midway in the upper surface. The bone's exterior was somewhat smoothed and polished. One complete whistle, 10.2 cm. long with a diameter of 7 mm., and fragments from seven broken ones were obtained. Three retain traces of asphalt stops, built up near their holes. No specimen gives evidence of having been bound to another. The bone whistles all lay in the upper portion of the refuse deposit from 10 inches below the 36 surface to a depth of 6 feet. Tubular whistles are frequent in Bay and Valley middens (Gifford 1940:183). They are attributed to both the Middle and Late horizons (Beardsley 1948:13, 16). Fish vertebrae beads -- Fifteen centrally perforated fish vertebrae have their edges carefully worked down. Eight were found together; 2 additional vertebrae were associated; the remaining 5 occurred as isolated specimens. All were obtained in the upper three to eight feet of the deposit. The pierced vertebrae, presumably beads, are small, averaging about 1.5 cm. in diameter. The fish species represented is the thresher shark (see Appendix B). Miscellaneous bone objects -- A heterogeneous lot of bone articles includes a bipointed mammal bone splinter 13.6 cm. long, with one tip polished from use, perhaps as an awl or perforator. Two distal ends of deer cannon bones have been extensively ground on both sides of the articulation. One has shallow pits on both surfaces, as if a perforation had been started. Their purpose is unclear. An elk ulna, unmodified except for extensive battering on the edge opposite the proximal epiphysis, perhaps saw employment as a hammer or club. A heavy split section of elk long bone (tibia?) and a splinter of sea mammal bone (whale?) also exhibit scarred edges, indicating utilization as pounders. Three pieces of split mammal bone, 7.1 to 8.3 cm. long and 1.3 to 1.4 cm. wide, are cut obliquely at one end, resulting in a blunt point. The opposite end is square-cut. All show some smoothing. A highly polished bit of bone has a narrow, parallel-sided neck, which expands to a blunt point. This object, 1.7 cm. long and 6 mm. wide, is presumably part of a larger implement. Eight scraps of worked bone are too fragmentary to be identified as artifacts. Antler The shellmound people utilized both deer and elk horn in making tools, but neither very extensively. The antler objects are not well preserved and some have become so badly decomposed that it is difficult to determine their original form and dimensions. The porous material apparently decayed rapidly because its large cells and open structure permitted free access of oxygen and dampness. The range of implement types is small, wedges, flakers, punches, and spatulas comprising the total. Wedges -- Antler wedges vary considerably in size, from small ones, apparently designed for fine work, to large, heavy implements suitable for splitting thick branches or even logs. The tools were made by tapering a section of antler to a rounded and beveled-tip. The butt end usually shows scars from the effects of pounding. Longer specimens tend to show the natural of the antler. Two classes are represented, the main differences between them being size and method of beveling the blade. a. Short, broad, blade beveled from side (22 specimens). Made from short lengths or split sections of antler, the blades on 37 these wedges have been tapered by cutting and grinding from one surface only (P1. 5, h,i). The butts of the tools have been cut off square. Their length varies from 10 to 15 cm.; the width of the blade ranges from 3 to 3.5 cm. b. Long, narrow, beveled from both sides (30 specimens). Wedges included here are made from sections near the tip of the antler (P1. 5, f,j). Their blades have been ground from both surfaces to give a relatively narrow, rounded tip. Like the preceding group, they have square-cut bases. On the whole, these wedges are more carefully made than those of the first class. In length they vary from 12 to 22.5 cm. and in width from 2 to 3 cm. Antler wedges were found throughout the mound from a depth of three to four to more than 16 feet beneath the surface, with most of them found below the eight to nine foot level. Both classes showed about the same vertical occurrence. Only one specimen was taken from a grave (Burial No. 32). If these objects were used exclusively for woodworking, their presence in some numbers points to a well-developed wood industry. No specialized mauls were unearthed, but any of the hammerstones could have been used to pound in the wedges. Antler wedges have been reported from other Bay middens, but Emeryville is the only site where they were met with in comparable quantity. Here, as at West Berkeley, the wedge was the most common antler artifact, with some indication of a more frequent occurrence in the lower levels of the deposit (Schenck 1926:229-230). The Ponce mound also yielded a fair quantity, even though excavations were extremely limited (Gifford 1940:182). Antler wedges are rare items in the delta region with only one reported from Early horizon settlements and a few more from later sites (Heizer 1949a:28; Gifford 1940:182). Flakers -- Antler tines with cut bases were present at all levels. The tines had received no intentional shaping, but their tips exhibit wear, presumably from flaking stone by the pressure technique. Both straight and slightly curved specimens are included, with a unique piece consisting of a branched tine. Nineteen complete flakers, 5.7 to 13.7 cm. long, and 16 fragments were recovered from depths ranging from four feet from the surface to 14 feet. Curved blades -- Two whole and five fragmentary objects comprise split sections of antler, evidently elk, ground into flat, blunt-pointed blades. They still show the natural curvature of the horn (P1. 5, k,l). The largest specimen has a length of 46.2 cm. and a concave base; the second, quite similar, measures 15 cm. less and has a straight rather than concave base. The original form and size of the incomplete blades could not be determined. The objects could have functioned as sweat-scrapers or strigils or even as sickles. Animal Teeth Twenty-one modified animal teeth must have served as pendants or beads. A sea lion canine is cut off square at the root end and 38 has three small grooves around its circumference. Traces of asphalt and cord wrappings are visible near the squared end, indicating its suspension as a pendant by wrapping the root end with a thin, two-ply cord, held fast with asphaltum. From two graves at the north end of the mound (Burials 84 and 85) came 20 coyote teeth, 18 in one grave and 2 in the other. The teeth are undrilled, but bear asphalt and cord impressions. Beads and pendants made from animal teeth are not common in Central California sites. Unperforated canid (coyote) teeth occasionally unearthed have been with Early horizon burials in the delta region (Heizer 1949:48). Drilled coyote teeth have also been found. Shell At West Berkeley shell was used almost exclusively for the making of beads and pendants. Only three kinds, Red Abalone (HaZiotis rufescens), Black Abalone (Haliotis cracherodii), and Olive (Olivella bipZicata) were regularly utilized. The making of shell ornaments does not seem to have taken place at the site for the refuse failed to yield discarded waste fragments, incomplete articles, or pieces broken during manufacture. Drills suitable for piercing shells were lacking. Thus, it can be concluded that finished products were brought in from elsewhere. Either the West Berkeley people journeyed to the seacoast to gather shells and there made ornaments from them, or more likely, they procured the finished products in trade from shore-dwelling populations. Beads -- Beads usually lay near the neck or thoracic region of skeletons. All are well-made but shaped rather simply. Six types are represented. a. OZiveZZa with spires removed (1,195 specimens). Beads consisting of whole Olive shells with the tip or spire ground off down to the main whorl (P1. 6, l,f), found in 10 lots, show a complete intergradation in size from tiny specimens measuring only 6.9 mm. in length to large ones of 13.2 mm. The beads recovered together were not carefully graded according to size. b. Rectangular OZiveZZa (350 specimens). These thin and slightly concave beads have straight edges and square corners (P1. 6, k,l). The central perforation is drilled from one side only. Four lots of 168, 152, 25, and 5 were secured. There is some size variation from 4.1 by 5.3 mm. to 6.6 by 8.6 mm.; perforations range from 12. to 1.7 mm., with the average falling near 1.5 mm. c. Circular VZiveZZa (2 specimens). Two circular, slightly cupped- Olivella beads were found together (P1. 6, j,h). Each has a biconically drilled hole in the center. Their diameters measure about 8.7 mm. d. Rectangular iaZiotis (412 specimens). Rectangular or, in a few instances, almost square, beads cut from abalone shell were 39 recovered in four lots, numbering 243, 87, 64 and 13. Each bead has a single central or slightly off-center preforation, drilled from both sides (P1. 6, i,i). The beads' edges are unmodified except for the original cutting; the angles of the corners are sharp. The shell's coarse back was cut away so as to exhibit the inner irrides- cence. The size range is from 5 X 6 mm. to 6 X 17 mm.; perforations average about 2.5 mm. e. Circular HaZiotis (1 specimen) -- A single, centrally perforated abalone shell bead, 14 mm. in diameter, was found. It is slightly cupped due to the utilization of a curved fragment for its manufacture. The back of the shell has been ground away. f. Limpet (1 specimen). The aperture of a small limpet (Acmaea sp.) shell beads, appears to have been enlarged by grinding; the shell may represent a completed bead or even a pendant. Its natural opening certainly made it suitable for suspension. It was possible to detect a stratigraphic difference in the occurrence of shell bead types (Table 8). Circular forms remained limited to the higher part of the deposit, whereas rectangular beads were distributed in the deeper levels. The pair of disk-shaped OlivelZa beads were obtained at a depth of 42 inches; the circular abalone at 60. These may be too few to be made the basis for statements concerning stratigraphy, though their complete absence from the lower 13 feet of the midden seems significant. Except for a specimen in a necklace of spire-lopped shells associated with an infant, buried 85 inches down, rectangular OZivella beads were all recovered at depths from 146 to 171 inches. The rectangular Haliotis forms run from 101 to 172 inches. Olive shells with their spires removed had the greatest depth range, from 72 to 172 inches. Beads of the last three forms were sometimes strung together in a single necklace. Shell bead types have been recognized as reliable indicators of culture periods in Central California since the people of each prehistoric phase tended to use distinctive forms. Of the West Berkeley types, the spire-lopped Olive ha is the least useful as a horizon marker because of its wide geographical and temporal range. In the delta region whole shells occur in all periods, with the Early beads being typically small (Gifford 1947:10). For the Bay area, this type was abundant at Emeryville but almost absent at Ellis Landing and Stege, only one specimen having been recovered from the last two sites. The other West Berkeley forms have more diagnostic value. Circular OZive ha bipZicata beads with a central hole are characteristic of the Middle horizon in the Valley (Lillard, Heizer and Fenenga 1939:391-392). Two beads of this type were found at Emeryville and Ellis Landing (Schenck 1926:233-234; Nelson 1910:398). Round and flat abalone shell beads are diagnostic of Middle horizon sites. Rectangular OliveZZa shell beads of the variety recovered at West Berkeley occur only in Early horizon sites with a smaller, thinner bead with a tiny perforation found in Late horizon deposits (Heizer 1949a:17). The latter seems to be the form reported for Emeryville (Schenck 1926:233). Rectangular to square HaZiotis pieces 40 are standard in Early horizon settlements (Heizer 1949a:17). The Haliotis beads from Emeryville, which vary from circular to rectangular, are not of this type (Schenck 1926:233). To sum up, the shell beads found exclusively in the upper levels at West Berkeley represent types generally ascribed to the Middle horizon; those from the deeper stratum are Early horizon forms. The spire-lopped Olives cannot be assigned to a specific chronological period though their apparent absence in the upper 72 inches of the midden may have temporal significance in the San Francisco Bay region, particularly in view of their almost complete absence in two nearby shell middens. Pendants -- Pendants are all made from abalone shell. The species could not always be identified because of alteration but when recognizable it was either HaZiotis rufescens or cracherodii. The shell pendants, thin, concave objects, and drilled for suspension, undoubtedly served as articles of personal adornment, either attached to clothing or as ornaments worn about the neck. Some were associated with beads, indicating their use as parts of necklaces. The pendants assume a number of distinct shapes. a. Circular, two central perforations, plain or incised edges (11 specimens). Eight of these pendants exhibit incised borders while three have unmodified margins (P1. 6, np,j2). Four show traces of asphalt or other adhesive on the backside and may represent earplug or labret facings. Their diameter are from 18 to 51 mm.; perforations vary from 2.3 to 3 mm. b. Circular, two central perforations, serrated edges (13 specimens). These specimens consist of disks with scalloped or serrated borders (P1. 6, a,b). They are much like the above but with smaller diameters and larger perforations. The size range is from 14.4 to 20 mm.; perforations vary from 2.5 to 3.3 mm. c. Circular, single central perforation, incised edges (1 specimen). This single-holed pendant, 18 mm. in diameter has incised borders (P1. 6, o). d. Rectangular with concave sides, two perforations at narrow end, plain edge (3 specimens). The general form of these pendants is rectangular with the sides curving inward (P1. 6, r,s). The most finely finished example measures 18 by 35 mm.; a second larger and cruder one has dimensions of 25 by 42 mm. The third is incomplete. The method of finishing their margins varies: one has plain edges; a second, incised; and the third, a partially serrated border. e. Rectangular, one peripheral perforation, plain edge (3 specimens). The three specimens of this class are long and narrow (P1. 6, t,u) with curvature of the shell making them somewhat asymmetrical. Dimensions of two of the pieces are 18 by 50 mm. and 10 by 54 mm. The third is incomplete. f. Triangular, single peripheral perforation, plain edge (4 specimens). Three small, roughly triangular pendants are made 41 from rim sections of a Haliotis rufescens shell. The shell's curvature adds to their asymmetry. All are crudely finished. They measure 6 by 23 mm., 11 by 20 mm., and 11 by 20 mm. A fourth specimen, similar in outline, has a second perforation drilled near its lower border. g. Indeterminate. A fragmentary pendant has two peripheral perforations and a third drilled slightly below. Its original shape and dimensions could not be ascertained. Little can be said about the stratigraphy of pendant types because their number is small and depth information is inadequate because of errors and omissions in field recording and in cataloguing. Further, the majority of the pieces were taken from two graves. Six circular pendants with two central holes, the disk with a single perforation, and two of the three rectangular specimens with concave sides were found with Burial 45 at a depth of 172 inches. Nine of the disks with scalloped edges came with Burial 66, 166 inches below the surface. As a group, the West Berkeley shell pendants are distinct from those recovered at other shellmounds on the shores of San Francisco Bay, but several forms are very similar or identical to those from lower Sacramento Valley early horizon cemeteries. The most frequent Early pendant, as at West Berkeley, is circular with two central perforations (Heizer 1949a:17). Like some of the West Berkeley specimens, the reverse surface often has been smeared with asphaltum. The distinctive rectangular pendant with concave sides is also found in Early horizon graves. Circular disks with deeply serrated or scalloped edges generally are regarded as belonging to the Middle horizon (Heizer and Fenenga 1939:392). No such quantity and variety of shell ornament was present at West Berkeley as in the delta region. The relative scarcity of shellwork is also characteristic of other Bay mounds. Evidently, the Bay area people failed to develop a distinctive art in shell (Gifford 1947:50). The suggestion that this reflects their economic status may be correct (Schenck 1926:232). The bayshore dwellers probably did not have desirable trade items to exchange with the coast tribes for shell articles. Apparently the inland peoples did. 42 Table 8 Shell Artifacts Artifacts Number Size Range (mm.) Depth (in.)

Shell rarely served utilitarian purposes. Occasionally empty mollusk valves were utilized in their natural state as containers. An unmodified Bay Mussel (My tiZus eduZis) shell was found filled with red ocher; a few others showed traces of pigment. Some employment of shells as scrapers or knives is demonstrated by the presence of three roughly rectangular sections, cut from the borders of valves of the larger Sea Mussel (My tiZus californianus). Each of the pieces shows wear on one edge. A section of mussel shell with a cut and rounded border may have been similarly used or may have operated as an artificial thumbnail in extracting fibers from leaves and stalks. Ten additional severed pieces are too fragmentary for their original shape and possible function to be ascertained. Several small masses of 72 - 172 146 - 175 42 101 - 172 60 172 129 - 162 172 172 85 136 43 powdered (clam?) shell were discovered. Their compact shape suggests that they had been in containers of perishable material. Baked Clay A hand-molded chunk of fired clay, 2 cm. long and 6 cm. in diameter, was obtained at a depth of 150 inches. Made from reddish clay, blackened on one side by fire, it is roughly oval in form, with a plain, irregular surface. Baked clay objects, so numerous in interior sites of Central California, are generally lacking in San Francisco Bay shellmounds, though a few have been found. A baked-clay ball and a "biscuit-shaped" fragment were excavated at Emeryville (Schenck 1926: 225). This rudimentary fired-clay industry is represented in all of the three lower Sacramento Valley horizons, though rather weakly in Early settlements (Heizer 1949:25). The West Berkeley specimen is too generalized in form to be definitely linked with any of the Valley types though it does bear a vague resemblance to the ungrooved biconical clay balls of the Early horizon. That the West Berkeley specimen was locally made seems doubtful. Perishable Materials Soil conditions were not favorable for the preservation of perishable materials, so little has survived. There is one piece of basketry, saved from destruction by charring and a protective coating of pitch and hematite. The fragment, found at 127 inches, is small and crumbly, making recognition of its structure exceedingly difficult and identification of fibers impossible. The weaving technique appears to be lattice-twining, weft elements passing around both vertical and horizontal warps. It is closely wove, with 14 warps and 25 wefts per 10 cm. The pitch of the stitch is down to the left. If the identification is correct, this is an early indication of a rather rare basketry technique. A mass of carbonized fibers was uncovered at 127 inches. The strands are long and rows of them seem to cross at right angles, suggest- ing a remnant of a checker-weave mat of shredded bark or tule. A second bunch of fibers is too poorly preserved for ascertaining whether they were woven. Though no actual cordage was found, the presence of a fine two-ply string is attested by impressions in asphalt on the ends of charmstones and canid teeth. House Remains and Other Features Architectural evidence was meager at West Berkeley but fireplaces and concentrations of burned and cracked stones were plentiful. A single storage pit was also exposed. Houses -- When excavation began, no pits or other surface indications of houses were visible. This is not surprising, considering 44 the disturbed condition of the midden and its antiquity. Little subsequent evidence concerning habitations was obtained. Three compacted areas were noted, one with a fire pit near its center. These may well have been remnants of house floors but the absence of defined postholes makes this uncertain. The only indubitable structural remains, uncovered at a depth of 123 inches, consisted of a section of the floor of a large, presum- ably ceremonial, house. The floor, a two-three inch layer of clean, hardpacked, yellow clay spread over 5 by 12 foot area, sloped inward toward the center, forming a broad shallow depression, 4 to 6 inches deep. Its edge was marked by a curving line of 9 post molds, spaced 8 - 12 inches apart. Seven additional postholes lay inside the circle. Two of the latter had raised clay rims on their outer edges, apparently added for greater support. A single large posthole was observed outside the house outline. Profiling the postholes showed that they were pointed or slightly rounded at the base. Their diameters varied between two and five inches and their depths from four to six inches. All tended to slope inward at the top, suggesting a conical or domed framework once covered the floor area. The house floor could not be completely exposed, for it lay on the edge of the excavated area next to the factory building. As a consequence the exterior form of the structure could not be determined with any exactness but it seemed to be an oval, perhaps 40 feet long and 20-25 feet wide. No definite entranceway could be observed and there was no fireplace. An intrusive pit from a level two to three feet higher cut through one corner of the floor. Four inches below, the house floor, separated from it by a thin deposit of charcoal and calcined shell, lay another thinner clay band, perhaps remains of an earlier house. Fireplaces -- Small areas of charcoal and ash, 15 to 16 inches across, were frequently met with. They were not contained in defined pits nor regularly surrounded by stones. Of 21 recorded, only six had fire-blackened rocks irregularly arranged around them. Several charred twigs and a handful of burned acorns were taken from one of the hearths. Concentrations of stone -- Sixteen masses of cracked and irregularly broken stones, often fire-stained, were exposed. In size the individual stones ranged from 8 to 30 cm. Fragmentary and, occasionally, complete lithic artifacts were intermingled. The largest concentration covered a 5 X 10 foot area; the smallest 2 by 3 feet. Their vertical distribution was from 5 to 14 feet. Storage pit -- An oval, sand-lined pit, 19 by 24 inches in diameter and 12 inches deep, was encountered 180 inches down. Over it lay several red sandstone slabs. The pit contained whole and broken mussel and oyster shells but no artifacts. 45 Mortuary Practices During the excavation of the West Berkeley shellmound, 95 more or less complete skeletons and a number of disassociated human bones were exhumed.1 Most of the skeletal material was in poor condition; many of the bones had become badly decayed and crumbly, making exposure and removal difficult. The poor preservation can be explained by several factors. Many skeletons had been badly broken up as a result of lying in shallow graves and being subjected to pressure from human activity above; others had been disturbed by later aboriginal digging of graves or other pits. The cutting away of the east section of the mound close to a cemetery in order to make way for a railroad spur track exposed many skeletons to the forces of disintegration. The prehistoric people habitually interred their dead directly in the village debris. It appears that burials were made in the midden during all stages of its formation for skeletons were encountered at all levels, from about 2 feet 4 inches below the surface to the subsoil. Relatively few clearly defined burial pits or grave walls could be discerned. All were shallow (2-1/2 to 3 feet deep), oval hollows, averaging about 24 by 36 inches in dimensions. Burials occurred in all parts of the mound but there were two areas, apparently cemeteries, in which they were concentrated. Unfortunately neither could be satisfactorily explored. The first lay on the midden' s eastern fringe where operations had to be limited because of the danger of undermining a heavy wire fence and a railroad track. This cemetery yielded 7 skeletons, several badly disarranged, and deteriorated. Five others were observed in the trench walls but could not be exposed. During bulldozing of the northern section, 20 skeletons or more were noted in a small space. It was possible to remove only 12, all severely damaged by the earth-moving operation. The West Berkeley mound-dwellers placed corpses in the ground in a loosely flexed position with the arms bent so that the hands lay near the face (P1. 7). No customary direction of orientation could be detected. In 19 graves the skull was oriented to the west and in 23 to the east. Twenty-two showed the head placed in a northerly direction, 9 roughly toward the south. For 22 burials, orientation could not be determined or went unrecorded. A similar variation in the body's position was noted. The skeleton lay on the right side in 33 instances, on the left in 23. Eight skeletons appeared to be on the back, six on the face; it is possible that some of the latter originally lay on the side but were shifted in the settling and movement consequent to decomposition. One interment was doubtfully reported in a sitting position. Placing more than one body in a grave does not seem to have been a common practice as only three occurrences were observed. 1 Ten skeletons uncovered by Peterson in 1904 were included. The later section on human skeletal remains describes some material omitted here for which there are no burial data. 46 Depositing articles with the dead either was not a well- developed custom, or it was reserved for special individuals. Only 32 of the 95 burials had accompanying mortuary goods and of these at least five represent doubtful associations. In 11 graves, offerings remained limited to beads or ornaments. Objects of daily use were not regularly placed with the dead and the apparent intentional inclusion of animal remains was noted only three times. The "killing", or purposeful damaging, of burial objects was reported once -- a mortar accompanying Burial 2 had a hole knocked through its base. Forty- three bodies showed signs of powdered pigment. For 42 burials, this consisted of red ocher or hematite; one (Burial 10) had traces of yellow-brown limonite. In only 13 graves was the red ocher profuse. There is no need to describe the burials in detail since the data for each are presented in Table 9, but Burial 32, a young adult male, probably merits special attention. It was the only one which accom- panied a fair number of burial gifts. Two large obsidian blades and a pair made from a white chertlike material, as well as an antler wedge and a grooved net sinker, were found in the grave. Red ocher colored most of the bones and the bases of the two obsidian blades. The practice of laying burials in a flexed position in refuse mounds was common procedure in prehistoric California. All San Francisco Bay sites thus far reported upon have yielded flexed burials. At Emeryville this seems to have been the universal rule and, as at West Berkeley, little attention was given to orientation or position of the torso (Schenck 1926:197). For Ellis Landing, flexure was the prevailing method, again with no observance of cardinal direction (Nelson 1910: 382). Several skeletons at this site lay stretched out instead of contracted. The occurrence of human remains is reported for the Stege mounds but no information on body posture is given (Loud 1924: 360). At San Bruno both flexed burials and cremation were noted (Drake 1948:319). In the Bay shellmounds only a small percentage of graves contained artifacts and these when found were frequently restricted to shell beads and ornaments. The use of red ocher was general. A sequence of burial techniques has been worked out for interior Central California. Burials fully extended on the ventral side and oriented west characterize the Early horizon; flexed burials, usually tightly contracted, appear in the Middle horizon with some cremations; both cremation and flexed interment were practiced by the Late people with cremation becoming more frequent with the passage of time (Heizer and Fenenga 1939:385). A sequence has been suggested for the Bay and coast dwellers, with loose flexure, variable orientation and disposition, and scanty mortuary offerings characterizing Middle sites and these practices carrying over without marked change into the Late horizon, Phase I. Cremation appears to have been intro- duced in Late, Phase II times, just before European contact. The significance of sporadic extended burials in Bay shellmounds is not known. 47 Tab le 9 Burials Burial Depth Age Sex Position Orienta- Red Associated No. (in.) tion Ocher Objects 1* 78 Infant Back East Absent None 2 120 Adult M Back East Abundant Killed mortar, net sinker, rectang- ular beads 3 114 Infant ?

The animal had been placed in a shallow depression and purposefully covered over. Its remains lay in anatomical articulation, suggesting that the coyote was buried after having been halved longitudinally. This may represent an interment of an animal, ceremonially raised and killed. Thirteen coyote burials, some with offerings, have been reported from Late and Middle horizon sites in the Valley (Heizer and Hewes 1940: 589-590). The hindquarters of four were missing. Special post- mortem disposal of other mammal species has also been noted in the interior region. An almost completely articulated skeleton, consisting of the entire skull and mandible and most of the postcranial bones of a large raptorial bird, was uncovered 123 inches down in the refuse. The remains were identified as those of a California Condor, the state's largest living bird. The completeness of the skeleton again implies special or ritual sepulture, perhaps mortuary treatment similar to that accorded humans (Wallace and Lathrap 1959). The bones of large carnivorous birds, eagles, hawks, and condors, have been unearthed elsewhere in California under conditions suggesting careful postmortem treatment. Ethnographic data indicate ritual disposal of birds killed during ceremonies by recent California Indians (Heizer and Hewes 1940:391). A fairly large number of condor bones were encountered at Emeryville (Howard 1929:314), all of the elements except one collected within the same small area and apparently representing a single individual. This may also have been an interment. A second bird skeleton igroved to be a member of the A&atisiae Family (ducks, geese). The skull had been badly crushed and was lying on the vertebrae. This probably does not represent an intentional burial but is merely a fowl which for some reason was not eaten after its capture. Subsistence Remains The enormous mass of molluscan valves contained in the West Berkeley midden shows that shellfish collecting remained the constant and principal means of gaining a livelihood throughout the period of occupation. The earliest inhabitants gathered vast quantities of mussels and oysters, both obtainable with relatively little effort and without special tools. Mussels were to be had merely by pulling them off rocks; oysters needed only to be scooped up at low tide from gravel bars. Later, clams replaced oysters as an important food item though an emphasis upon mussels continued (Appendix A). Procuring clams proved more arduous, for they had to be dug from mud and sand. 52 Fish must have been another mainstay of the aboriginal fare. The prominence of fishing is attested to not only by plentiful fish bones (Appendix B), but also by numerous net sinkers. From a time soon after their arrival, almost to the end of their residence, the shellmound people caught quantities of large fish in shallow offshore waters in nets weighted down with notched and grooved stones. A subsidiary device probably for supplying daily needs, consisted of a single-piece, curved bone hook. Hunting appears to have been a less significant method of procuring food than either shellfish collecting or fishing, though mammal bones were present in sufficient numbers to demonstrate that meat was a fairly regular dietary item. The favorite was venison, with sea otter meat becoming more popular in later times but never superseding deer flesh (Appendix C). Presumably, deer were killed with stone-tipped darts, hurled from a throwing board. How sea otter were captured remains unknown. Judging from the scarcity of their remains, small game animals were not hunted on any considerable scale. Bird flesh was also consumed in fair quantity for skeletal parts of various avian species were liberally sprinkled through the refuse. Most of the bones are those of migratory waterfowl, especially ducks and geese (Appendix D). Evidence as to how they were taken is lacking. It is difficult to estimate the extent to which vegetable foods were gathered and eaten for vestiges of them were rarely met with during the excavation. Identifiable specimens, all charred, consisted entirely of acorns. Despite this near absence of direct evidence, it can be safely assumed that vegetal products formed staple articles of subsistence. Proof of the utilization of wild plant foods comes from the finding of a substantial number of mortars and pestles, implements essential for their preparation. Conclusions and Interpretations The West Berkeley shellmound culture, as illustrated by the archaeological findings, represents a meager mode of existence, preoccupied with food-getting and showing few outstanding technical achievements. That its fundamental pattern, once established, never radically altered is demonstrated by the stability of a sizable number of customs and classes of objects. Subsistence activities, heavily emphasizing shellfish collecting, remained constant. General utility implements and tools -- mortars, pestles, hammerstones, wedges, bone awls and the like -- continued in use with minimal, if any, shifts -in form or relative abundance. Mortuary practices persisted and no change took place in the racial characteristics of the human population. Evidently, the last people to live on the midden were the cultural and physical descendants of its earliest residents. Although the same manner of living carried over in essence, new practices and items came into vogue from time to time. Most of 53 the additions and substitutions seem trivial, such as the introduction of a new form of shell bead or the dropping of the habit of perforating charmstones. The only fundamental change was the abandonment of the use of net-sinkers, presupposing the giving up of an important fishing technique. Innovations did not appear suddenly and all together in a group, but in vertical distribution within the refuse deposit, and therefore, in time of introduction, they tend to cluster around the six-foot (below surface) level. This clustering of new traits allows for the recognition of two cultural components, one characteristic of the upper six feet of the shellmound and the other of the lower 12 feet (Table 10).

A comparison of the more significant classes of West Berkeley artifacts with those from Emeryville and Ellis Landing reveals that certain basic traits are common to all three shellmounds. Mortars and pestles represent the characteristic grinding implements; a developed bone industry is found; shell beads and pendants comprise the typical articles of personal adornment. Food habits and methods of disposing of the dead are alike. Although essential cultural unity is evident, differences can be discerned. Some Emeryville and/or Ellis Landing items, including stone pipes, small projectile points, mica ornaments, charmstones with basal projections, fork-like bone or antler objects ("head scratchers"), eyed needles and entire abalone shells are absent at West Berkeley. 55 Others, for example, bone tubes, beads and whistles, are shared, but are present at West Berkeley in reduced numbers. A few groups of objects found in the three shellmounds differ in their stratigraphic distribution. Perforated charmstones came from the lowest Emeryville stratum; at West Berkeley they showed a wider occurrence, being absent only in the top-most six feet; their depth provenience for Ellis Landing is not stated. Nonperforated charmstones, confined to West Berkeley's higher cultural layer, were found scattered more or less throughout the other two middens.l Notched and girdled net- sinkers, unearthed in profusion below eight feet in the West Berkeley deposit, were virtually unknown at Emeryville. For Ellis Landing, stone weights were collected from the top and bottom of the refuse, being nonexistent in the middle part. Large, stemmed projectile points, the characteristic West Berkeley lower-stratum form, are not reported for Emeryville. One of four weapon tips from the shaft dug below water level at Ellis Landing is of this type; a second, smaller specimen', might be added. Finally, the West Berkeley assemblage includes a series of articles, all from deep down, which were absent in the other two shellheaps. Among them are chipped stone blades with squared bases, rectangular OZiveZZa and HaZiotis beads, circular abalone and other ornament forms. These diffferences in content and stratigraphy permit an ordering of the cultural layers of the three shellmounds. On the basis of shared traits, the upper six feet of West Berkeley can be equated with the lower 10-14 feet of Emeryville and the bulk of Ellis Landing. The bottom 12 feet of West Berkeley, which produced items absent at the other two sites, has no direct counterpart though there is a possibility, based on the scanty evidence of a plentiful supply of net-sinkers and two stemmed projectiles, that the Ellis Landing's deepest stratum overlaps somewhat. Conversely, the higher portions of Emeryville and Ellis Landing contained materials not represented at West Berkeley. Thus, it appears West Berkeley appears to have been the first of the three localities to have seen human occupation with Ellis Landing inhabited next and Emeryville last. There may have been a brief period when all three were inhabited simultaneously. West Berkeley became deserted first while people continued to live at both Emeryville and Ellis Landing for a lengthy span of time. At least nine additional San Francisco Bay shellmounds have produced materials analogous to these from the upper six feet of the West Berkeley midden (Beardsley 1954b: 100-102). The type of culture represented by the archaeological remains seems to have been widely distributed along the bay's shoreline. By contrast, only one local site, the University Village, near Palo Alto in San Mateo County, has yielded an assemblage comparable to that from West Berkeley's lower level (Gerow 1968). The projectile point traditions are equivalent and the mortar and pestle forms are much alike. Other duplications in stone objects include perforated charmstones, notched No charmstones were recovered in the bottommost Ellis Landing layer. Their absence may be due to accident as the chance is slight that items of such comparative rarity would have been contained in the small sample. 56 sinkers, and chrysotile asbestos rods. The San Mateo County site's bone industry appears less developed because, although awls, flakers, notched scapulae, split and polished elk ribs, and wedges are present, they appear in greatly reduced numbers. Essential uniformity can be seen in the shell beads and ornaments from the two middens. As at West Berkeley, the University Village people interred their dead in a flexed posture, with few grave goods and a sprinkling of red ocher. Little doubt exists that the two assemblages are closely related and overlap in time. Back from the bayshore, the lowest occupational level of the Stone Valley settlement, at Alamo in Contra Costa County, contained a preponderance of stemmed projectiles and other articles compatible with those of West Berkeley (Fredrickson 1965:20). The Stone Valley burial position was exclusively flexed. Unfortunately, there was a virtual absence of shell beads and only a limited repertory of bone articles. Cultural items from the deeper portion of West Berkeley show many correspondences to those obtained from Early horizon settlements in the lower Sacramento Valley (Heizer 1949a; Olsen and Wilson 1964). Besides shared specific forms, such as rectangular OliveZla and HaZiotis beads and circular shell ornaments, the West Berkeley weapon tips and knives, as a group, are like Early Sacramento specimens. Drilled charmstones, often phallic representations, are also held in common. These three groups of artifacts - shell beads and ornaments, projectile points and blades, and charmstones are regarded as important Early period diagnostics. Certain rare items, significant because of their uniqueness, such as bone fishhooks, asbestos-splinters, and bipointed bone objects, match Early forms. Other fundamentally similar, but less precise agreements, can be observed in bone spatulae, bird-bone awls, antler tines with cut bases, undrilled canid teeth ornaments, unmodified animal bones in graves, and the use of asphalt as an adhesive. Naturally, diversity in detail occurs, for culture identity hardly can be expected, even in localities so close geograph- ically. The Sacramento Valley assemblage is much richer and some of its distinctive traits, like extended burials accompanied by quantities of grave goods and the employment of milling stones are wanting at West Berkeley. Conversely, bay net sinkers have no inland counterparts, though fishing must have been a major economic activity in the lower Sacramento Valley, and the abundance of mortars, pestles, and bone artifacts is not repeated. The two populations differ in physical features, with the Early Valley people exhibiting greater size and ruggedness than the bayshore dwellers. The two West Berkeley components can be fitted into the temporal-cultural classification proposed for Central California (Beardsley 1948a:Table 1; 1954a:Table 1; Kroeber 1948:812; Heizer 1949a:33). The basic unit of this taxonomic scheme is the "component," the archaeological record of human habitation at a single locality at a specific time. Components which demonstrate strong cultural ties are grouped into a "facies." Related facies, in turn, are combined in a "phase" of a "horizon," the largest unit. Three of the latter, designated as Early, Middle, and Late, have been recognized. 57 Phases have been established for only the last of the three. The older West Berkeley materials can be considered as a component of a West Berkeley facies of the Early horizon (Table 11), not previously known for the San Francisco Bay area. It is somewhat differently conceived than the corresponding interior Windmiller facies. The University Village and Stone Valley assemblages also can be assigned to the West Berkeley grouping. A fourth component may have been present in the bottommost portion of the Ellis Landing shellmound. The upper level or latest West Berkeley component falls in the Middle horizon but its assignment to a facies is not easy. It does not correlate too closely with either of the two facies, Ellis Landing and Patterson, established for the San Francisco Bay area. The Middle period, as now conceived, covers a long time span (ca. 2000 years) and represents a loose grouping of components scattered over practically the entire bay region. There are probably significant temporal subdivisions, or phases, which need to be worked out. Judging from the relatively minor amount of artifactual material attributable to the Middle horizon, the occupation at West Berkeley came early and lasted for only a few centuries. After its abandonment in early Middle times, it never again experienced aboriginal habitation. No typical Late period objects such as lightweight arrowpoints or clam- shell disk beads turned up.1 Why the prehistoric West Berkeleyans departed remains a mystery. Perhaps their shellfish supplies, the primary attraction for settlement, became depleted and they shifted to a more favorable spot. Table 11 Cultural and Temporal Relationships Sugges ted Horizon Phase Facies Beginning Date Late II Fernandez A.D. 500 I Middle Emeryville 2500 B.C. Ellis Landing Patterson Early West Berkeley ? 1 The clamshell bead attributed to West Berkeley by Beardsley (1948:17) came from another locality. 58 Absolute dates for the two West Berkeley components support their chronological placement. Eight wood charcoal samples and one of oyster shell were collected for radiocarbon analysis. Because no concentrations or large chunks of charcoal were encountered, scattered bits were gathered from each 12-inch level and combined to make a sample. The shell came from a lens. The material was sent to the University of Michigan Memorial-Phoenix Project Radiocarbon Laboratory. As it was not possible to run all of the samples, when submitted, two, both charcoal, from culturally significant layers were selected, one from near the deposit's base, and the other from just below the presumed cultural break. Age determinations by the carbon dioxide gas method were: Sample No. Depth in inches C14 Date M-121 96-108 2200 + 400 B.P. M-127 192-204 2700 + 400 B.P. Although in proper depth relationship, the dates did not accord with the expected age. Later, the Michigan Laboratory re-ran more of the same two charcoal samples along with six additional ones. These analyses provided a series of dates which make sense. They are as follows (Crane 1956): Sample No. Depth in inches C14 Date M-121 96-108 2700 + 300 B.P. 745 B.C. + 300 M-122 132-144 3210 + 300 B.P. 1255 B.C. + 300 M-123 144-156 2880 + 300 B.P. 925 B.C. + 300 M-124 156-168 3500 + 300 B.P. 1545 B.C. + 300 M-125 156-168 3700 + 350 B.P. 1745 B.C. + 350 156-168 3860 + 450 B.P. 1905 B.C. + 450 M-126 180-192 3140 + 450 B.P. 1485 B.C. + 300 M-127 192-204 3700 + 300 B.P. 1745 B.C. + 300 Six of the series fall into a more or less consistent and orderly sequence; two (M-122 and M-126) do not. The anomalous dates can be regarded as "archaeologically unacceptable" and disregarded. Most securely fixed in time is the 156-168 inch level for which there are three C14 determinations, all falling within a reasonable range. The radiocarbon dates suggest that West Berkeley's occupation began prior to 2000 B.C. Three of the lower level determinations fall near 1800 B.C. Several hundred years must be added to this figure to allow for the accumulation of the basal 12-inch level, which contained 59 only a minute amount of charcoal, insufficient for dating purposes. The habitation period covered by the series of C14 dates is approxi- mately 1000 years. More centuries need to be granted for the buildup of the upper eight feet of the refuse, giving a total time span of perhaps 1300-1500 years. West Berkeley radiocarbon dates correspond reasonably well with those obtained for sites of comparable cultural content. The earliest determinations fall close to those of Blossom (CA-SJo-68), an Early horizon site in the lower Sacramento Valley (Heizer 1958). University Village has two younger dates, 2700 + 350 and 3150 + 300 years, and Stone Valley one, 4450 + 400 years (Fredrickson 1965:20). The West Berkeley 2700 + 300 determination for the 96-108 inch level is also of a degree of magnitude expectable on the basis of cultural comparison. It comes from below the line of assumed stratigraphic separation, with materials above ascribed to the Middle horizon. This is in general agreement with two C14 dates available for Middle occupa- tion zones at bayshore sites. Charcoal from a component of the Patterson Mound, assigned to the Ellis Landing facies, yielded an age of 2588 + 200 and 2090 + 220. A sample of charcoal and oyster shell from near the base of Emeryville has been dated at 2310 + 120 years ago (Hubbs, Bien and Suess 1962:208). As a concluding statement, it can be said that the West Berkeley shellmound proved to be of unusual significance to the understanding of San Francisco Bay's prehistoric past. Not only has the midden's excavation enriched the archaeological record with a considerable body of substantive data, but, more importantly, it extends knowledge of man's presence in the bay region farther back in time by providing the first clear-cut evidences of Early Horizon occupation, hitherto recognized only at inland localities. Major and minor differences in detail distinguish the bayshore Early manifestation from its interior counterpart, though there can be little doubt of their generic affinities. The shellmound exploration also demonstrated cultural dynamics for the San Francisco Bay area in a firmer way than previously, proof being based on cultural stratigraphy in a refuse deposit of relatively great depth. The archaeological findings make it clear that change came slowly and was unspectacular. No vital alteration in the mode of existence was accomplished during the lengthy habitation period and the last West Berkeleyans lived in much the same fashion as the site's earliest settlers. 60 Bibliography Beardsley, 1948 R.
