Cree. The western boundaries of this tribe in 1725 are uncertain. 
It appears to have reached its greatest expansion, west and north, 
bet wen 1750 and 1780, when it had raided up the Peace river into the 
Kocky mountains and traversed the whole of the Mackenzie river 
down to the delta. I have assumed that in 1725 it was separated from 
the Chipewyans by Churchill river, which was certainly the boundary 
in the middle of the century; but that it liad not yet reached the upper 
waters of the Mackenzie basin, or seized lake Athabaska, the Slave 
river, and the southeast part of Creat Slave lake, all of which 
districts it controlled ten or twenty yeai's, apparently, before the 
time of Hearne. 
Interior Salish. The small blue block within the territory 
of this group marks the location in the Nicola valley of an Atha- 
paskan-speaking tribe that disappeared early in the nineteenth 
century ( Teit. J.: “The Thompson Indians of British Columbia”; 
Memoirs of the American Museum of Natural History, volume ii. 
Publications of the Jesup North Pacific Expedition, \mlume i, p. 
166, New York, 1900 ). It is not clear what tribe, if any, claimed the 
headwaters of Fraser river towards Yellowhead pass in the eighteenth 
century. Early in the nineteenth some Interior Salish families 
(the Snare Indians of early writers) seem to have used it as a trap- 
ping ground; and a little later it was occupied by a group of mingled 
Salish, Iroquois, Cree, and Europeans. On the map it is coloured 
as Athapaskan territory, since the physiography of the region appears 
to favour its occupation in 1725 by the Carrier rather than by the 
Shuswap. Its occupation by the latter in the early nineteenth cen- 
tury would then correspond with the expansion of that tribe into 
the northern part of the Kootenay country at about the same 
period. 
Tsetsnut. James Teit, in some unpublished notes now in the 
possession of the National Museum, defined the territory of this tribe 
as follows: “ IJieir country lay in a strip from near Bradfield canal 
and the Iskut across the streams flowing into Behm canal perliaps 
to about the head of Boca de Quadra. They occupied all of the upper 
Portland canal around Stewart, and Salmon and Bear rivers. They 
may have come down to the canal as far as Maple bay. They 
occupied all the White river and Meziadin Lake basins and one of
