_Quenemsias._--These people, who lived near the two preceding tribes, are designated a "group" by Schenck (p. 136). They covered, according to him, "the southern part, or perhaps all, of Grand Island." The ecclesiastical diarists make no mention of them save the reference by Duran to the "isla llamada de los Quenemisias." One other citation is worth mentioning, however. In the Bancroft Transcripts is a document dated January 31, 1796, entitled "Informe en el cual el teniente Herm^{do} Sal manifesta lo que ha adquirido de varios sugetos para comunicarlo al Gobernador de la Provincia," which gives a description of the lower reaches of the San Joaquin and Sacramento rivers and the delta and mentions the natives (Sal, MS, 1796). In detail, the account is extremely inaccurate. However, one of the Indians "... dio noticia de las naciones Tulpunes, Quinensiat, Taunantoc, y Quisitoc: los primeros son de la orilla del estero; los 2^{os} estan del otro lado de los rios ..." Although no numerical data are given, the mention of the Quenemsias (Quinensiat) as a "nacion" in the delta region establishes them as a group of more than average importance. The mission books show 185 Quenemsias baptized at Mission San Jose. Roughly double the number of baptisms may be taken as the aboriginal population, i.e., 400. (Quenemsias ... 400) ____________________ _Chuppumne, Chucumes._--Schenck places these two settlements, which he calls villages, on the Sacramento River near the mouth of the Cosumnes. Most of our documentary information concerning them is derived from the accounts of Duran and of Luís Argüello. Luís Antonio Argüello accompanied Duran on his expedition and wrote a report to the governor in the form of a letter, dated May 26, 1817, the original of which is preserved in the Bancroft Library (library no. fm-F864A64; also typed copy). The existence of this letter evidently was not known to either Kroeber or Schenck. It is less complete and less detailed than the diary of Duran but it is of value in checking the statements made by the latter. On May 16 the party reached the foot of Grand Island and on May 17 proceeded up the left-hand (i.e., western) watercourse. The village of Chucumes was found 8 leagues (leguas) upstream, according to Duran, 13 miles (millas) according to Argüello. The latter estimate is probably closer, since Duran is notoriously inaccurate (usually on the side of overestimate) in his computation of distances. Here Duran counted 35 houses whereas Argüello says 36, a sufficiently close correspondence. As indicated previously, a population of 315 persons is probable. Continuing their journey, they went on for 4 miles (Argüello); Duran says approximately 3 leagues. There they stopped at a rancheria, "arruinada" according to Argüello, although Duran makes no mention of this.
