Benton on the I'd of January, and crossing
the Rocky Mountains by the way of what
is called the Blackfoot pass, arrived at

been very pild, and but little snow had fall

d For two weeks during this exploration Of
Lient g., the weather was severe and
stormy, but on an approach, in the yicini-

became more mild, and the valley was al
most entirely free from snow. b ..l .Ha
In The Bitter Root mountains, on the
trail of the main party of the exploration,
for the greater part of tho way between
Fort Owen and Walla Walla, no snow Of
any consequence was found but in the vi
cinity Of the Pond d'Orville Lake, and for
a route fifty miles east and west, where the
snow is now already the deepest, according
to old mountaineers, two feet and half
was found to be all that the extreme depth

bpt that beneficial resultsyill accrue by the
mission Of the Governor, in adding strength

to affect, in such an important manner, the
people of this territory, and of the coast
generally. His absence from the territory

the object sought to be accomplished BY
the legislature, is thought to BET superior to
almostiany other consideration Of territori-
