Only the Koyeti are described by the Spanish authorities hitherto consulted. Moraga mentions the rancheria Coyahete with a population of 400 in 1806. Estudillo in 1819 found a rancheria, which he called Arroyo de Copaipich, with 200 and one called Canyon Agspa with 400 people. The latter may perhaps be Moraga's Coyahete. If so, the tribe had a population of at least 600 in 1819, but it must have suffered some decline prior to that year. Latta's informants were able to remember 8 villages. Moreover, the tribe was oriented ecologically toward the Kaweah delta and oak forest, although it was actually situated on the lower Tule River. Thus an estimate of 800 persons would not be too much for the precontact period. The Yaudanchi on the upper Tule River also, according to Kroeber and to Latta, had 8 villages and covered considerably more territory than the Koyeti. Hence the same population may be ascribed to them. The Bokninuwad were evidently a smaller group, since Kroeber reports for them only two villages and Latta none. It would not be safe to allow them more than 200 persons. If we do so, then the tentative estimate for the three tribes must be put at a total of 1,800. For the remainder of the territory held by the Yokuts there are only two documentary references, the diaries of Garcés in 1776 and Zalvidea in 1806. Both these writers give population data which have been subject to considerable controversy. For the Buenavista region the four pertinent villages are mentioned by Zalvidea and are as follows: Village and Tribe Houses Men Women Children Total _________ ______ _____ _____ ________ _____ Malapoa (Tulamni) ... 29 22 8 59 Buenavista (Tulamni) ... 36 144 38 218 Sisipistu (Hometwoli) 28 50-60 ... ... ... Yaguelame (Yauelmani) ... 92 ... ... 300 From even casual inspection it is apparent that Zalvidea did not see the complete population of any one of these villages and that many of the inhabitants had been removed by previous expeditions or were in hiding. The village of Malapoa is small but presents no serious demographic discrepancies. The number of children was low, but as has been pointed out in a previous discussion Zalvidea was counting as men or women everyone over the age of seven years. The children, calculated according to his method, amounted to 13.5 per cent of the total.
