After this manuscript was completed, the writer had an opportunity to examine those documentary files of the Office of Indian Affairs and of the War Department which are at present in the National Archives at Washington. Several letters in the files containing information on the native population of the San Joaquin Valley have never, so far as could be determined, been published. Since the data thus procured are fragmentary and since they do not apparently invalidate the conclusions set forth in previous pages, they have not been incorporated in the body of this paper. These items, however, have some intrinsic interest and therefore merit specific mention. They are briefly abstracted as follows. _War Department_ _Record Group 98._ 10th Military Dept. Letters received Calif., Document no. _K 21_. E. D. Keyes, Camp Magruder, June 17, 1851. The 8 tribes on the Kaweah, with whom a treaty was concluded on May 30 contain 1,240 individuals. The 4 tribes on Paint Creek with whom a treaty was concluded on June 3 contain 1,660 persons. _Record Group 98._ Letters received Calif., 1854. Enclosure to document no. _W 2_. John Nugent, Camp Wessells, Dec. 31, 1853. The Four Creeks region (Kaweah) from the Sierra Nevada to Tulare Lake will not contain more than 1,000, all told. _Record Group 98._ Letters received Calif., 1854. Enclosure to document no. _W 12_. H. W. Wessells, Fort Miller, March 7, 1854. The Indians under control of Fort Miller include those on the Fresno, San Joaquin, Kings, and Kaweah Rivers. They are much reduced in numbers, owing to the recent sickness. Fresno River: 400 persons, including 100 able men. San Joaquin River: 350, including 80-90 able men. Kings River: 1,100, including 250 able men. Kaweah River: 800, including 200 able men. _Office of Indian Affairs_ _Record Group 75._ Letters received Calif., 1854. Enclosure to document no. _H 758_. D. A. Enyart, Fresno Reservation, Nov. 3, 1854. The Indians on the Fresno Farm include: 30 Chowchilla, 220 Choot-chances, 90 Pohonicha, and 100 Potohanchi. The Indians in Mariposa, Stanislaus, and Tuolumne counties do not exceed a total of 2,000. By river system he breaks them down thus: 300 on the Merced, 350 on the Tuolumne, 250 at Plant's Ferry on the Stanislaus, 100 elsewhere on the Stanislaus, and 100 scattering through the country. _Record Group 75._ Letters received Calif., 1855. Enclosure to document no. _H 1050_. Report of D. A. Enyart, Fresno Reservation, Aug. 22, 1855. "I find that there are at least about 1,000 to 1,500 Indians on the River (i.e., San Joaquin).... This does not include the 'Mono' tribe which is the most numerous of any tribe...." _Record Group 75._ Letters received Calif., 1859. Enclosure to document no. _M 66_. M. B. Lewis, Fresno Agency, Aug. 30, 1859.
