Great numbers of Indians came from both villages and delayed the greater part of the day without tradeing a single horse. ... they asked nearly half the merchindize I had with me for one horse. ... the nativs requested the party to dance which they very readily consented and Peter Cruzat played on the violin and the men danced several dances & retired to rest in the houses of the 1st and second Chief. ... all of those articles they precure from other nations who visit them for the purpose of exchangeing those articles for their pounded fish of which they prepare great quantities. This is the great mart of all this country. ten different tribes who reside on Taptate and Catteract River visit those people for the purpose of purchaseing their fish, and the Indians on the Columbia and Lewis's river quite to the Chopunnish Nation visit them for the purpose of tradeing horses buffalow robes for beeds, and such articles as they have not.

This was a pleasant day. As we did not expect to be able to navigate the Columbia river much farther, Captain Clarke, with some of the men and some goods went over the river to endeavour to procure some horses. I was out hunting this morning and killed a rattlesnake among the rocks. Some hunters that went out in the morning returned in the evening and had killed two deer, some ducks and four squirrels, three of a beautiful speckled kind, and as large as a common grey squirrel, but the tail not so bushy.
