Creek, we emerged on the Saskatchawan Plains, just six geo- 
graphicai miles north of the 49th parallel, and camped at Water- 
ton Lakes two miles east of the mouth of the pass. 
The position of the Waterton Lakes, as will be seen.on the 
plan, is just where the offset range, before spoken of, strikes out 
to the eastward from the main chain, having the Chief’s Moun- 
tain at its extremity. The uppermost and largest of these lakes, 
lies in a gorge in the mauntains, and is crossed by the boundary 
line; the scenery here is grand and picturesque, and I took care 
to make a sketch from the narrows between the upper or south- 
ernmost and second lake.

pine which M. Bourgeau, the botanist of the expedition, had

the sake of the horses, and in order to examine more carefully 
the nature of the country. Game was abundant, including 
grizzly bears, and we obtained both fresh meat and fish. The

It will be seen that some of the waters of the Saskatchawan 
take their rise from the offset range at the boundary line, and 
from information gained from the Indians, I believe there is a 
tributary of the South Branch, which rises to the southward of 
the Chief's Mountain, this may be the Bull-pound River of Ar- 
Towsmith ; if so, this offset range has nothing to do with divid- 
ing the waters of the Missouri and Saskatchawan, and some 
the waters of the latter must come from American ground. igs
