er in their original
country at Round Mountain, California.

GEOGRAPHIC DISTRIBUTION.

The eastern boundary of the Yanan territory is formed by a range of
mountains a little west of Lassen Butte and terminating near Pit River;
the northern boundary by a line running from northeast to southwest,
passing near the northern side of Round Mountain, 3 miles from Pit
River. The western boundary from Redding southward is on an average 10
miles to the east of the Sacramento. North of Redding it averages double
that distance or about 20 miles.

YUKIAN FAMILY.

= Yuki, Powers in Cont. N.A. Eth., III, 125-138, 1877 (general
description of tribe).

= Y['u]-ki, Powell in ibid., 483 (vocabs. of Y['u]-ki, H[-u]chnp[-o]m,
and a fourth unnamed vocabulary).

= Yuka, Powers in Overland Monthly, IX, 305, Oct., 1872 (same as
above). Gatschet in Mag. Am. Hist., 161, 1877 (defines habitat of
family; gives Yuka, Ashochemies or Wappos, Shumeias, Tahtoos).
Gatschet in Beach, Ind. Misc., 435, 1877. Bancroft, Nat. Races, III,
566, 1882 (includes Yuka, Tahtoo, Wapo or Ashochemic).

= Uka, Gatschet in Mag. Am. Hist., 161, 1877. Gatschet in Beach, Ind.
Misc., 435, 1877 (same as his Yuka).

X Klamath, Keane, App. Stanford's Comp. (Cent. and So. Am.), 475, 1878
(Yukas of his Klamath belong here).

Derivation: From the Wintun word yuki, meaning "stranger;" secondarily,
"bad" or "thieving."

A vocabulary of the Yuki tribe is given by Gibbs in vol. III of
Schoolcraft's Indian Tribes, 1853, but no indication is afforded that
the language is of a distinct stock.

Powell, as above cited, appears to have been the first to separate the
language.

GEOGRAPHIC DISTRIBUTION.

Round Valley, California, subsequently made a reservation to receive the
Yuki and other tribes, was formerly the chief seat of the tribes of the
family, but they also extended across the mountains to the coast.
