[Clark] This morning we had Some dificuelty in Collecting our horses notwithstanding we had hobbled & Picqueted those we obtained of those people. we purchased two other horses this morning and 4 dogs. we exchanged one of our most indeferent horses for a very good one with the Choponnish man who has his family with him. this man has a doughter now arived at the age of puberty who being in a certain Situation—is not permited to acoiate with the family but Sleeps at a distance from her father's Camp, and when traveling follows at Some distance behind. in this State I am informed that the female is not permited to eat, nor to touch any article of a culinary nature or manly occupation. at 10 A. M. we had Collected all our horses except the White horse which Yelleppit the Great Chief had given me. the whole of the men haveing returned without being able to find this hors. I informed the chief and he mounted Capt Lewis's horse and went in Serch of the horse himself. about half an hour after the Chopunnish man brought my horse. we deturmined to proceed on with the party leaving one man to bring up Capt L.—s horse when Yelleppit Should return. We took leave of those honest friendly people the Wallah wallahs and departed at 11 A. M. accompanied by our guide and the Chopunnish man and family. we Continued our rout N. 30° E. 14 ms. through an open leavel Sandy Plain to a bold Creek 10 yards wide. this stream is a branch of the Wallahwallah river, and takes it's rise in the same range of mountains to the East of the main branch. deep and has a bold Current. there are maney large banks of pure Sand which appear to have been drifted up by the wind to the hight of 20 or 30 feet, lying in maney parts of the plains through which we passed to day. This plain as usial is covered with arromatic Shruubs, hurbatious plants and tufts of Short grass. Maney of those plants produce those esculent roots which forms a principal part of the Subsistance of the Nativs. among others there is one which produce a root Somewhat like the Sweet potato. We encamped at the place we intersepted the Creek where we had the pleasure once more to find a Sufficency of wood for the purpose of makeing ourselves comfortable fires, which has not been the Case Since we left Rock fort Camp below the falls. Drewyer killed a beaver and an otter. the narrow bottoms of this Creek is fertile. tho' the plains are pore & Sandy. the hills of the Creek are general abrupt and rocky. there is Some timber on this Creek. it consists of Cotton wood, birch, the Crimson haw, red willow, Sweet willow, Choke Cherry, yellow Current, goose berry, white berried honey suckle, rose bushes, Seven bark, Shoemate &c. &c. rushes in Some pats of the bottoms.
R. Fields over took us with Capt Lewis's horse our Stock of horses have now increased to 23 and several most of them excellent young horses, but much the greatest part of them have Sore backs. those Indians are cruel horse masters; they ride hard and their Saddles illey constructed. &c. &c.
Our Party, after having suffered greatly to scrounge up a half dozen cayuses, now finds themselves with 23, including the elusive elegant all white horse given Captain Clark. Saddle sores can take a very long time to "hair over" or heal, and usually are often, easily skinned again. The great treatment the group received from the Walla Walla's must rank way up towards the top of the order.
