With the Kato we arrive at an area where it becomes possible to utilize historical and documentary, as well as ethnographic, sources of information. For the period 1850-1856 there are three accounts left us by white men who were direct observers, as distinguished from data supplied from memory to modern white men by Indian informants. With respect to the region north of San Francisco Bay these observations by Americans must be regarded as supplementary to the basic ethnographic material derived from Indians. Nevertheless they are of considerable value in confirming, negating, or modifying the ethnographic data.
Two primary sources are pertinent here. The first is the expedition of Colonel Redick M'Kee, one of the three "commissioners" sent out in 1851 to negotiate treaties with the California Indians. M'Kee went first to Clear Lake, then up the Russian River, over to the Eel River watershed, down to Humboldt Bay, and eventually up the Klamath and Trinity rivers. Two records of this expedition were kept. The first, and far better known, is the Journal of George Gibbs, which was later published by Henry R. Schoolcraft (1860). The other is the Minutes of the expedition, written by John M'Kee, a relative of the Colonel. These Minutes, together with considerable correspondence, were published in Senate Executive Document No. 4, 33rd Congress, Special Session (1853).
The second source is a report written by Major H. P. Heintzelman at the request of Indian Agent Henley, in 1855. Major Heintzelman (1855) made a survey of the tribes of Sonoma and Mendocino counties which might be placed upon a reservation at the mouth of the Noyo River. He interviewed numerous headmen, or chiefs, of community units and reported on the Indian population. His total, for the territory extending from the upper Eel River to San Francisco Bay was 21,200, a figure in excess of the value conceded by ethnographers.
According to George Gibbs (1860, p. 118), the M'Kee expedition, on August 30, 1852, reached the Batimdakia (spelled also Ba-tim-da-kia) Valley, which was supposed to be at the head of the South Fork of the Eel River. John M'Kee implies that this valley was on the Middle Fork of the river but there is little doubt, judging from the route taken, that it was actually Long Valley, on the east branch of the South Fork. He says that the valley was inhabited by the Cabodilapo tribe and that a careful count showed 497 Indians. Since not all the natives could be located, John M'Kee estimated the actual population as 500 to 600. In a letter from Redick M'Kee to the commissioner in Washington, dated September 12, 1852 (1853, p. 185) it is stated that the population "may be" 600. M'Kee's counts, particularly in the Clear Lake Region, are generally regarded as too low. Hence his figure of 600 for Long Valley must be considered conservative. It should also be borne in mind that M'Kee saw only the east branch of the South Fork of the Eel River, which takes its origin in Long Valley. He did not get over to the west branch, which runs through Kato territory past Branscomb. Now Barrett shows eleven villages on the east branch and its tributaries, or an average of 55 persons per village. At the same rate the six villages on the west branch would add 330 for a total of 930 in the southern range of the Kato.
Heintzelman lists a group of seven names, representing Indian communities, which he says are up to 35 miles north of the site selected for the reservation, i.e., Fort Bragg, or the mouth of the Noyo River. Heintzelman's distances and locations, as well as his names, are exceedingly hazy. Some of the seven names mentioned may refer to the northern Pomo, and some very likely pertain to the coast Yuki. Nevertheless two are undoubtedly Kato: the Car-toos and the Ba-tims (the former is cognate with Kato, and the latter must refer to Batimdakia Valley). The aggregate population is 700, according to Heintzelman. This is only slightly larger than M'Kee's 600. Allowing for conservatism on the part of M'Kee and over-liberality by Heintzelman, a fair estimate is 650. Alternatively, since Heintzelman saw the country three years after M'Kee had passed through, and the population may have diminished somewhat, the figure 700 secured by Heintzelman may well refer to both branches of the South Fork of the Eel.
For the Laytonville-Branscomb area we now have three estimates: by derivation from purely ethnographic data, 800; from the M'Kee reports, 930; and from the Heintzelman report, 700. Regardless of minor detail, the first method seems to yield results entirely consistent with direct contemporary evaluation.
Adding 300 to account for the remaining Kato territory we may retain the estimate of 1,100 for the tribe as a whole.
