Concerning the Hoyima there are two references, one by Pico in 1826 and one by Rodriguez in 1828. Pico states merely that he attacked the rancheria and captured 40 gentiles and 1 Christian, a fact which in itself would not furnish a very significant clue to population. He also noted "mucha guesamenta y cueros casi frescos de caballada que habian matado."
The account by Rodriguez is more circumstantial. This soldier went along the San Joaquin River in late April of 1828. On the 24th he sent a group of men to scout the "rancheria de los Joyimas, que es adonde an comido la caballada." At dawn the next day they attacked the village, "que estaba en medio de los dos brazos del rio" (the San Joaquin west or northwest of Fresno). He captured 26 Indians and 27 animals (horses). Another 60 or 80 horses escaped "en el monte." At about this time a gentile captain came from a rancheria designated Guche or Getche, depending upon how one deciphers the handwriting of the manuscript. He "vino a los Joyimas a comer caballo." The rancheria named here is probably that of the Heuchi on the Fresno River. This gentile said there was another rancheria "mas arriba" at which there were horses. Rodriguez sent Simeon Castro to investigate. He found no one at the rancheria mentioned but went on 2 leagues to another rancheria, likewise deserted but containing the carcasses of 100 dead horses, which had been slaughtered and were about to be eaten. It was noted by Rodriguez that: "Estas 3 rancherias son una misma que es la de los Jaimes." It was also remarked that the rancheria was divided when the horses arrived in order to eat with less fear of detection. From this account it is clear that the Joyimas had at least three villages. Allowing somewhat over 300 persons each, the population of the group would reach 1,000.
The slaughtered horses open up an interesting field of speculation. It is clear that by 1828 large segments of the aboriginal population had entirely given up the sedentary ancestral mode of life in favor of an existence based upon stock raiding. To do this it was necessary to recast village life completely—as is suggested by the fact that the rancheria was "divided" when the horses arrived. In order to catch the horses for food other horses were essential for rapid transportation to and from the coastal settlements. New arts and skills had to be learned, and new categories of labor had to be evolved.
Rodriguez found among the Hoyima as a whole 87 to 107 live horses (27 captured, 60-80 in the wilderness), which were presumably about to be killed and eaten, together with 100 animals already slaughtered. The total thus reached approximately 200. The question now is pertinent: how much food can be obtained from 200 horses? If we assume that each of these relatively light range animals weighed 800 pounds, we may deduct about 25 per cent to account for bones, hide, certain of the viscera, and other inedible parts, leaving 600 pounds which the Indians could and did consume. The aggregate is 120,000 pounds of meat. If this meat was dried and preserved, according to general practice, it was sufficient to supply 329 persons the equivalent of one pound of fresh meat per day for one calendar year. If it had to be consumed immediately or within a few days, and if every man, woman, and child ate 20 pounds apiece, it was adequate for 6,000 people. If the entire tribe, not merely one rancheria, divided the meat into equal shares, and if the tribe numbered 1,000 persons, then the share of each individual amounted to 120 pounds. Whether these figures are strictly accurate is irrelevant. They merely emphasize that a quite sizable group must have been concerned. We may therefore regard the Hoyima as being as large a tribe as the Pitcache, and estimate that the population was at least 1,000.
The remaining two tribes in the valley proper, as listed by Kroeber and others, were the Heuchi and the Chauchila. They occupied the north bank of the Fresno River and the distributaries of the Chowchilla River. The ethnographic data include no more than one or two villages for each tribe. The Heuchi are referred to by Rodriguez, who says that the rancheria of the "Jeuche" was completely deserted. However, since it was the principal tribal village, it must have contained at least 200 persons. The Chauchila were also noticed by Rodriguez, who says that at "Chausila" he "captured" 142 people and "killed many." If we concede that as many escaped as were captured or killed, there must have been fully 400 in all.
The Nupchenches, although they are merely mentioned as a possible tribe by Kroeber (Handbook, p. 485) and are doubtfully recorded by Schenck (1926), occupied an important position in the early nineteenth century. Indeed, the failure of Kroeber and Schenck to consider them seriously makes it necessary to set forth in some detail the information about them contained in the Spanish reports.
These natives were distributed along the San Joaquin River from its big bend near Mendota to approximately the mouth of the Merced (see map [4], area 5A). The first mention of them is by Moraga in the diary of 1806. He found two rancherias, Nupchenche with 250 people and Cutucho with 400 souls which was "junto a la primera llamada Nupchenche." This means that Cutucho was close to but at that time not necessarily part of Nupchenche. From the description in the diary Nupchenche was situated at or near the mouth of Santa Rita Slough in T9S, R12E, and this is almost exactly where Schenck places it on his map (Schenck, 1926, p. 133). The next visitor who left a record was José Dolores Pico in 1815. On November 7 he left San Luis Gonzaga in western Merced County (in approximately T10S, R8E) and went east to the Tulares at "Arroyo nombrado San Jose," which was close to the rancheria of the Cheneches. At dawn of the 8th he attacked the village and captured 66 persons, but "... la mayor parte de esta gente se fue pr estar dha rancheria en mal parage." The gentiles said that 4 leagues up the San Joaquin River was Nupchenche, thus placing Cheneches on the river in the southern part of T8 S, R11E. This location checks well with the statement made elsewhere in the diary by Pico that Cheneches was near the junction of the San Joaquin and "Las Mariposas," or Mariposa Creek. If Pico captured 66 persons but "the majority" escaped, the total number must have reached from 200 to 400, if not more.
Pico then scouted Nupchenche and learned that all the inhabitants had fled. He therefore by-passed the village and went 8 leagues southeast up the San Joaquin to the rancheria Copicha. This rancheria, which by the way must not be confused with the Cutucho of Moraga, was thus located on the river several miles north of Firebaugh, probably near or in T11S, R13E. As a check on this location is Pico's further statement that Copicha was in the valley of the San Joaquin "junto del Tecolote," or the Chowchilla. On November 10 he moved 8 leagues southeast from Copicha and saw horses from the rancheria Tape, which, from the distances, was near Mendota. This view is supported by Estudillo, who saw the region in 1819 and says that the spot "... donde Tape tenia su rancheria" was 24 leagues south of Cheneches and 25 leagues north of Notonto. Actually, Mendota appears to be approximately halfway between these two points.
Pico mentions one other village, Malim, which he places near Cheneches. Confirmation is found in a letter of Fr. Marcelino Marquinez (MS) on May 25, 1816, stating that the Cheneches recently have killed two Christians from Malim. The latter rancheria thereupon allied itself with Notoalh and Luchamme. No other trace of the two last-named villages is found.
Other writers who mention the Nupchenches group include Fr. Antonio Jaime, who mentions Cutuchu (MS, 1816) as a rancheria from which Soto brought back gentiles, and Ortega, who, in his 1815 diary, mentions Cupicha as having been attacked by Pico. Finally Inocente Garcia in his manuscript of 1878 records an expedition against the Nupuchineches under Ignacio Vallejo. The rancheria, even in the 1830's was "muy Populosa." The expedition captured 100 warriors and 300 of all ages and sexes, arguing a population of over the 300 claimed as captives.
