The Aboriginal Population of the San Joaquin Valley, California
Part 10
This account deserves comment on several grounds: with relation to Viader's visit of the previous year and the baptisms at San Francisco it is evident that whereas the southern extension of the Tarquines' habitat, whatever its size, had been swept clear prior to 1810, nevertheless the tribe persisted on the estuarine islands in truly large numbers. Moreover, since there is evidence of no more than one rancheria on the south shore, it appears that the territory in that region allotted by Schenck to the tribe is too large and should be restricted to a small area of the southeastern corner of Suisun Bay.
With respect to population, Abella's figures are quite credible. It has been suggested that one of the huge houses found in this region could accommodate 9 persons without difficulty. Then the large village should have had 540 inhabitants. Allowing 24 houses for the other villages seen, 216 persons should be added, making a total of 756, a figure not far from Abella's guess of 1,000.
The final reference to the tribe occurs in the diary of Duran. During the night of May 22-23, 1817, he went up the main channel of the San Joaquin, in T3N, R4E, and passed the Tauguimenes on the _left_, that is to say, on the _east_ bank. Schenck thinks that the group covered the entire strip from Pittsburg to the east bank of the main river _contemporaneously_. Now it has been pointed out as probable that the southwestern outliers were missionized, or pushed back into the swamps, as early as 1801. It is equally possible that the island communities described by Abella in 1811 were pushed, in the next five or six years, off the islands altogether and clear back eastward to the far bank of the main river. Of considerable significance is the fact that whereas both Viader and Abella mention the Tarquines as being in the estuary region, Duran, who covered this area thoroughly, is completely silent with regard to their presence. It is highly unlikely that, had there been any of the tribe left in their former habitat, he would have failed to note them.
The details are very obscure but the main outlines of events in the first three decades of the nineteenth century can be perceived. Aboriginally and perhaps till nearly 1800, there was a dense population of natives extending from Port Costa along the southern shore of Suisun Bay and up the rivers for fifteen miles beyond Antioch. Among them were included tribal groups, or rancherias, called Aguastos, Chupunes, Ompines, Julpunes, and Tarquines, belonging very likely to different ethnic and linguistic stocks. Under the pressure of the Spanish military power, which was the real force behind missionization, portions of these groups were exterminated, other segments gave ground and shifted habitat, and occasional remnants persisted in the old localities. Thus each visitor in turn found a different geographical organization, until the entire native society was obliterated.
An accurate assessment of aboriginal population in this area is impossible. The best we can do is try to make an intelligent guess. Several methods are available for this purpose--group comparisons, mission figures, area comparisons.
Throughout the plains of the lower San Joaquin and Sacramento valleys the native social units appear to have resembled rather uniformly the political organization of the Yokuts in the central and southern San Joaquin Valley. There were aggregates, or communities, consisting of perhaps one, but usually more than one, village, and occupying a more or less clearly defined territory. These groups, as they may be called, can be identified by the plural names which are ordinarily attached to them--the Bolbones, the Leuchas, and so forth. Naturally these groups varied considerably in size, and concerning no single one of them can we be absolutely sure of the number of their people. Nevertheless, if we had data concerning enough of them, the variations due both to inherent difference and to inaccurate estimate would tend to cancel out and an approximate average could be secured. No pretence can be made that we have enough estimates to establish a mean which would be statistically satisfactory. Nevertheless, as so frequently happens when we are dealing with data of this character, we have to employ the information available to us or forsake the problem entirely.
We have hitherto considered a number of the local groups mentioned above and have estimated their population as follows: Bolbones (restricted group, see p. 58), 1,500; Jusmites, 300; Tugites, 500; Nototemnes, 200; Leuchas, 900; Ochejamnes, 750; Guaypem, 300; Quenemsias, 400; Chucumes and Chuppumne, 1,500. The average for the nine groups is 705 or, in round numbers, 700. If we consider that the Aguastos, Chupunes, Ompines, Julpunes, and Tarquines were groups of the same character as the foregoing, then their total population may be taken as 3,500.
The total baptisms shown in the mission books of the five northern missions (in fact, only San Francisco and San Jose) for these groups is 911. In previous instances we have estimated the aboriginal population by doubling the baptism number. This procedure is admittedly purely arbitrary and based upon the general consideration that, except for small local populations relatively close to the mission, it was impossible for the missionaries and soldiers to prevent the escape of a sizable fraction of the people. Of the five groups here discussed, the Aguastos, it is evident, were completely missionized or at least obliterated. A much greater proportion of the other tribes survived, as is attested by their probable migrations up the rivers. Hence for the entire population it is doubtful if even one-half received baptism. Using the value of one half, the aboriginal number would have been approximately 2,000.
Linear distances along streams are useful as a basis for comparison in country where the rivers are similar ecologically but are clearly separated spatially and where the human population is concentrated along the stream banks to the exclusion of the interfluvial hinterland. Where a territory is marked by a network of creeks and sloughs, and the intermediate land is marsh, the linear comparisons become impossible. Areas must be substituted.
In relation to the present problem three such areas may be delineated. The first comprises the territory of the Bolbones (including all the subordinate villages) and the Leuchas. Following Schenck's map, it embraces all the land between the channels of the San Joaquin plus a strip approximately two miles wide east of the main river in T1 and 2S, R6E which accounts for the Leuchas. The area, as projected from a large-scale map onto coördinate paper, is 775 square miles, the population 3,400, and the density 4.39 persons per square mile. The second comprises the home of the Ochejamnes, Guaypem, Quenemsias, and Chucumnes-Chuppumne. For the habitat of these groups we have followed Schenck as far as possible. Our line runs actually from the junction of the east and west channels of the Sacramento at the foot of Grand Island southeast to the main channel of the San Joaquin, thence northeast and north to just east of Walnut Grove and then, at a distance of about 2 miles east of the eastern channel of the Sacramento, to a point 4 miles north of Courtland. Here the line crosses the river and continues downstream, 2 miles west of the river, to the starting point. This strip of the western bank of the western branch of the Sacramento is included in order to take in the Chucumes, who may have lived on the west side of the river. The area of this territory is 330 square miles, the population 2,950, and the density 8.94 persons per square mile.
The third area is the one shown by Schenck as belonging to the Chupunes, Tarquines, Julpunes, and Ompines, with the exception of the region east of the San Joaquin attributed to the Tarquines. For reasons stated previously the author does not believe that the Tarquines occupied this spot aboriginally. A strip 2 miles wide is included on the north shore, however, between Rio Vista and Collinsville, in the probable land of the Ompines. The eastern boundary is formed by the borders of areas one and two. In area three there are 600 square miles. The mean of the densities of the other two areas is 6.67 persons per square mile. Hence the population would have been 4,002 persons. No significance should be attributed to the third and probably also the second digit in these numbers. They are used only for purposes of estimate.
The three methods employed have yielded respectively 3,000, 2,000, and 4,000 as the most likely population of the five groups here being discussed. In default of any other evidence we may take the average 3,000.
(Chupunes, Tarquines, Ompines, Julpunes ... 3,000) __________________________________________________
Adding the totals for the tribes known to inhabit the delta region of the great rivers and the southern shore of Suisun Bay, we arrive at a total population of 9,350.
Delta area ... 9,350 ____________________
It is now preferable to depart from a strictly tribal sequence and revert once more to a classification based upon river basins. Three areas of this type are sufficiently clearly marked out; those corresponding to (1) the Cosumnes River, (2) the Mokelumne River, and (3) the lower San Joaquin River from just below the Merced to the head of tide water near Manteca. The inhabitants may be designated village or tribal groups in accordance with the river system where they were located.
_The Cosumnes group._--On the river of this name lived the large and important aggregate of peoples known popularly as the Cosumnes, which included a restricted tribelet or subgroup also called Cosumnes. Ethnically a portion of the Plains Miwok, they extended from Sloughhouse close to the foothills, along the lower course of the Cosumnes River to its confluence with the Mokelumne near Thornton, and from that point northwestward to the Sacramento. The tribe as a whole was divided into either villages or tribelets, the names of many of which have come down to us from the Spanish records or have been ascertained by informants from ethnographers. As might be expected, there is considerable confusion among the different sets of names.
The mission documents are replete with village and tribal names but the number of baptisms was not as large as might be anticipated from what must have been a very populous aggregate of natives. The reason probably lies in the fact that missionizing expeditions to the Cosumnes were preceded by exploratory and punitive expeditions which, to be sure, brought home a few converts but which were chiefly preoccupied with military objectives. The Cosumnes, together with the Mokelumnes and other peoples of the lower San Joaquin Valley, had the time and the opportunity to develop great facility in the raiding and stealing of livestock and consequently for many years were in a state of uninterrupted war with the coastal settlers. The bitter hostility thus generated, together with the aggressive psychology which accompanied successful physical opposition to the Spaniards, made extensive conversion to Christianity very difficult. As a result the relative proportion of the natives baptized was unquestionably much lower than among the bay and delta tribes previously considered. The baptisms which appear in the mission records follow.

Total 804
If we apply the general principle used with the delta groups and double the baptism number, the population becomes 1,608, a figure which is much too low. The Lelamne, with 128 baptisms, comprises the group attacked by Soto in 1813, at which time we have estimated that there were four villages of 475 persons each involved in the battle. This calculation implies a total of 1,900 for the Lelamne alone. On the other hand, the account is not entirely clear as to whether or not there were members of the Cosumnes tribelet concerned. If so, we may be dealing with both the Lelamne and adjacent neighbors who were designated locally Cosumnes. If we include the baptisms of all those under both names, we have 212. Furthermore, the Junisumne (or Unsumne or Anizumne) were often confused with the Cosumnes. If the 363 baptisms listed under the Junisumne are added we get 575 and, multiplying by 2, the population of the three divisions collectively would have been 1,150. This estimate also appears too small and leads to the conclusion suggested above on historical grounds that a baptism factor valid for the delta would not be applicable to the Cosumnes group as a whole.
Another documentary source is of interest in this connection. This is the account by José Berreyesa in 1830 (MS) of an affray along the lower Sacramento River in which Americans participated under Ewing Young. Christian fugitives from the missions had been protected by the Yunisumenes (Junisumne), who had joined with the Ochejamnes. They were opposed by the Mexicans and their allies, the Sigousamenes (Siakumne), the Cosomes, and the Ilamenes. These last tribes had gathered an army of 450 "Gentiles auciliares." The Yunisumenes, Cosomes, and Ilamenes are, of course, precisely the three subtribes discussed in the preceding paragraph. Now if the Sigousamenes, Cosomes, and Ilamenes contributed 450 men collectively, they each may be considered to have furnished 150 men. Since the opponents were fairly well matched, it is likely that the Yunisumenes supplied a similar number. We can assume that for routine fighting of this sort, particularly where two of the tribelets were ranged with the Mexicans instead of against them, the armies included no more than the strictly military population, or not in excess of half the males over the age of ten years. Hence, if the sex ratio was unity and the young children constituted approximately 15 per cent of the population, the aggregate number of the three subtribes would have amounted to 1,920, or almost the same as was estimated from the Soto report in 1813 for the Lelamne (Ilamenes) above, or perhaps the Lelamne augmented by some of the Cosumnes tribelets or subtribes. The Berreyesa episode occurred in 1830, after all these groups had suffered twenty years of attrition owing to perpetual minor warfare, disease, and starvation. Hence the population of the three tribelets jointly, Junisumne, Cosumnes, and Lelamne, must have reached fully 3,000 in 1813. The baptism factor, consequently, would not have been 50 per cent, but 575 divided by 3,000, or 19.2 per cent.
Three other villages or tribelets which can be identified in the mission records as being closely associated with the Cosumnes are the Amuchamne, Sololumne, and Locolumne. The first two probably correspond to Merriam's Oo-moo-chah and So-lo-lo, which in later times at least were rancherias. Assuming all three to have been villages, we may consider that each contained an average number of 300 inhabitants. The respective baptism numbers were 13.6, and 52. In relative terms the baptisms amounted to 4.3, 2.0, and 17.3 per cent.
The last division listed above is the Gualacomne, synonymous with Merriam's Wah-lah-kum-ne. Merriam (Mewko List, MS) places them between the lower Stanislaus and the Tuolumne rivers, but quotes Hale, who saw them in the 1840's, as saying that they lived on the lower east side of the Sacramento River. Hale's statement is strongly supported by the fact that they appear in J. A. Gatten's census of 1846 (MS, 1872). Gatten ennumerated only the tribes along the lower Sacramento. Whether the Gualacomne can be affiliated with the Cosumnes ethnically is doubtful but it is reasonable to include them with this group demographically.
Of the Gualacomne 158 were baptized in the missions. That the group was fairly large is attested by the fact that Gatten reported, under the name Yalesumne, that 485 were alive in 1846, Since no open valley group could possibly have retained more than one-third of its former members in 1846, it does not seem excessive to ascribe 1,455 persons to the tribelet. The baptism factor is 10.8 per cent, and the average of the five values secured with the Cosumnes group is 10.7, or, let us say 10.0 per cent. The total population on the lower Cosumnes and adjacent Sacramento rivers, according to the discussion above would be 5,355 souls.
We may approach the problem from a different direction if we start with the villages compiled by Merriam (1907, p. 349). He mentions sixteen villages on the Cosumnes River system from Sloughhouse nearly but not quite to the Sacramento. It is extremely probable that there were other villages on the Sacramento River itself. Nevertheless, let us take Merriam's list as it stands. The upper seven villages lie between Sloughhouse and the junction of the Cosumnes River with Deer Creek, the remainder below that point. Of the lower nine we may consider that four correspond to those seen by Soto, which were quite large. It was estimated that they contained 475 persons apiece. The other five lower villages, although perhaps not so populous, must have held fully 300 inhabitants each. The upper seven were no doubt smaller but still should have reached the values given by Moraga for similar stretches of the Tuolumne and Merced, i.e., approximately 250 persons. The total would then come to 5,150, very close to the previous estimate. It will be both adequate and conservative to establish the population at 5,200.
Cosumnes group ... 5,200 ________________________
_The Moquelumne group._--Here are included the Indians living on the lower course of the Mokelumne River, the Calaveras River, and the plain between the two. Five tribes mentioned by the Spanish writers fall within this category: the Moquelumnes, the Siakumne, the Passasimas, the Yatchikumne and the Seguamne. The exact territorial status of these tribes has been a subject of considerable disagreement among ethnographers.
The original Moquelumnes of the Spaniards were undoubtedly located on the Mokelumne River itself from Campo Seco nearly to the junction with the Cosumnes at which point they adjoined the Cosumnes tribe. According to George H. Tinkham, in his History of San Joaquin County (1923), they extended in a north-south direction all the way from Dry Creek to the Calaveras River, but by the middle of the nineteenth century they may have spread out from their original habitat. The Yatchikumne are shown by Schenck as filling the space between the lower Mokelumne and the lower Calaveras and extending westward to the San Joaquin River. Merriam (Mewko List, MS) quotes F. T. Gilbert to the effect that they occupied the Mokelumne River basin, but if they did so, it was because of the displacements during the mining era. The Passasimas are placed by Schenck on the left bank of the Calaveras River at, and for several miles upstream from, its junction with the San Joaquin River.
The Siakumne and the Seguamne are subject to some confusion. This difficulty arises partially from the similarity in name. The Siakumne are called Si-a-kum-ne by Merriam and Sakayakumne by Kroeber. In Gatten's census of 1846 they appear as Sagayakumne. In the San Jose baptism book we find Ssicomne, Zicomne, Siusumne, and Sigisumne. The Seguamne, on the other hand are designated Seguamnes and Saywamines by Merriam and Sywameney or Seywameney by Sutter in his New Helvetia Diary (1939). Gatten calls them Sywamney. They appear in the San Jose record as Secuamne, Seguamne, Seyuame, and other variants.
The Siakumne lived somewhere between the Calaveras and Stanislaus rivers according to Merriam, who places one of their villages at Knights Ferry on the Stanislaus. Schenck doubts Merriam's location and Kroeber puts the rancheria Sakayakumne as far north as the Mokelumne. Sutter (1939, p. 88) says that some of these people came to work for him, an unlikely event if they had been living as far away as the Stanislaus. It is probable that the lower Calaveras River is as close as we can place them. The Seguamne are not mentioned at all by Schenck. Merriam (Mewko List, MS) says they were a "tribe or subtribe on E. side lower Sacramento River" and may have been a subtribe of the Bolbones. Sutter and Gatten both refer to the tribe, and the sphere of activity of these men did not extend much below the Sacramento River itself. Hence, although there are grounds for including the Seguamne with the Bolbones or the Cosumnes, no serious error will be committed by placing them in the Mokelumne group.
The Moquelumnes were unquestionably quite numerous. In Spanish and Mexican times they were the most aggressive and belligerent of all the valley tribes and gave the coastal settlers a very rough struggle. Nevertheless, in spite of their detestation of the missionaries they furnished 143 converts between 1817 and 1835. At a ratio of 10 per cent this would mean a population, prior to the mission period, of about 1,400 souls. J. M. Amador (MS, 1877, p. 43) says that once, during the later colonial period, they furnished 200 auxiliaries, a fact which would argue fully 1,000 people at the time. Gatten in his census of 1846 gives them a total of 81 persons but G. H. Tinkham says that in 1850 or thereabouts they possessed four sizable villages with four chieftains. This may have meant between 200 and 400 persons, a really considerable number of survivors for a tribe which had suffered so extensively in the preceding three decades. These indications, and it must be admitted that they are only indications, would lead one to infer that the aboriginal population reached at least 1,500.
Precisely because the Moquelumnes were so brutally handled in the colonial era the modern ethnographic accounts of villages are very incomplete. Neither Merriam nor Schenck gives us any list. Kroeber puts three on his map (1925, opp. p. 446): Mokel (-umni), Lelamni, and Sakayak-umni. I think we are now in a position to state that these names represent former tribes and if they were applied to villages by informants, it is because the component units had shrunk to very small size.
Stream density comparisons are of value for the Mokelumne group. On the Cosumnes River, from Sloughhouse to Thornton, Merriam shows thirteen rancherias (omitting those close to the Sacramento River). As was proposed above we may ascribe from 200 to 400 inhabitants to each of these, say on the average 300. Now there is no reason to suppose that the Mokelumne River from the San Joaquin-Calaveras county line to just west of Lodi was less heavily populated than the Cosumnes. If so, the number of villages per linear river mile must have been very nearly the same. For the stretches under consideration there were 24 miles on the Cosumnes and 22 on the Mokelumne. Thus we would get 12 villages and 3,600 persons living on the Mokelumne River.
