... purchase some horses of the Indians; ... the natives were unwilling to barter, ... continued up it about four miles to another village of the same nation with whom we remained last night. here we halted and informed the natives of our wish to purchase horses; the[y] produced us several for sale but would not take the articles which we had in exchange for them. they wanted an instrument which the Northwest traders call an eye-dag (a sort of war hatchet) which we had not.

... procured two dogs of them and departed.

The morning was fair. The Commanding Officers attempted to purchase some horses, but could not agree with the Indians on the price; se we proceeded on about 4 miles to another village, at the mouth of the Catarack river. Here we got some Shap-e-leel, a kind of bread the natives make of roots, and bake in the sun; and which is strong and palatable. Here another trial was made to get some horses, but without success; and we again proceeded on; passed a place where there was a village in good order last fall when we went down; but has been lately torn down, and again erected at a short distance from the old ground where it formerly stood. The reason of this removeal I cannot conjecture, unless to avoid the fleas, which are more numerous in this country than any insects I ever saw.

About three o'clock in the afternoon we came to Rock Camp, where we stayed two days as we went down. some hunters went out in the evening and killed a deer.
