Capt. Clark killed a buffaloe and 4 deer in the course of his walk today; and the party with me killed 3 deer, 2 beaver, and 4 buffaloe calves. the latter we found very delicious. I think it equal to any veal I ever tasted.

We proceeded on early; and had a fine clear morning, but cold: there was a sharp frost.   We saw a great number of elk, buffaloe and deer on both sides of the river. About 12 the wind again rose and was disagreeable, but we continued our voyage.  Two of our hunters went out this afternoon and caught three young buffaloe calves.  We passed a small river called White Clay river on the North [The captains' White Earth River, today's Little Muddy River.] side and having gone 15 miles encamped on the South side.
