This morning we had some difficulty in collecting our horses notwithstanding we had hubbled and picquited those we obtained of these people. we purchased two other horses this morning and several dogs. we exchanged one of our most indifferent horses for a very good one with the Chopunnish man who has his family with him. this man has a daughter new arrived at the age of puberty, who being in a certain situation [WC?: mences] is not permitted to ascociate 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 permitted 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 yellept had given Capt. C. the whole of the men soon after returned without being able to find this horse. I lent my horse to Yellept to surch Capt. C's about half an hour after he set out our Chopunnish man brought up Capt. C's horse we now determined to leave one man to bring on my horse when Yellept returned and to proceed on with the party accordingly we took leave of these friendly honest people the Wollahwollahs and departed at 11 A. M. accompanyed by our guide and the Chopunnish man and family. we continued our rout N. 30 E. 14 ms.  through an open level sandy plain to a bold Creek 10 yds. wide.  this stream is a branch of the Wallahwollah river into which it discharges itself about six miles above the junction of that river with the Columbia. it takes it's rise in the same range of mountains  to the East of the sources of the main branch of the same. it appears to be navigable for canoes; it is deep and has a bold current. there are many large banks of pure sand which appear to have been drifted up by the wind to the hight of 15 or 20 feet, lying in many parts of the plain through which we passed today. this plain as usual is covered with arromatic shrubs hurbatious plants and a short grass.  many of those plants produce those esculent roots which form a principal part of the subsistence of the natives.  among others there is one which produces a root somewhat like the sweet pittaitoe.—  we encamped at the place we intersepted the creek  where we had the pleasure once more to find an abundance of good wood for the purpose of making ourselves comfortable fires, which has not been the case since we left rock fort camp. Drewyer killed a beaver and an otter;  a part of the former we reserved for ourselves and gave the indians the ballance. these people will not eat the dog but feast heartily on the otter which is vastly inferior in my estimation, they sometimes also eat their horses, this indeed is common to all the indians who possess this annimal in the plains of Columbia; but it is only done when necessity compells them.— the narrow bottom of this [X: Wallowwallow] [EC: Touchet] creek is very fertile, tho' the plains are poor and sandy. the hills of the creek are generally abrupt and rocky. there is a good store of timber on this creek at least 20 fold more than on the Columbia river itself.  it consists of Cottonwood, birch,  the crimson haw,  red-willow, sweetwillow, chokecherry yellow currants,  goosberry, white-berryed honeysuckle rose bushes, seven bark, and shoemate.  I observed the corngrass  and rushes  in some parts of the bottom. Reubin Feilds overtook us with my horse. our stock of horses has now encresed to 23 and most of them excellent young horses, but much the greater portion of them have soar backs. these indians are cruell horse-masters; they ride hard, and their saddles are so illy constructed that they cannot avoid wounding the backs of their horses; but reguardless of this they ride them when the backs of those poor annimals are in a horrid condition.
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.

Clark which diseased. had not the use of hir limbs. he brought a fine horse and gave Capt. Clark for doctering hir he gave meddicine and told them how to apply it &C. Capt.

M we got our horses up by the assistance of the Indians and Set out. proceeded on over Smooth barron Sandy plains not a tree nor Shrub to be seen except a weed or Shrub like wild hysop  which is common. the natives use it when dry for fires to cook with &C. the Indian name of it is cum-cum.  we came about 16 miles and Camped  on the wala-wal river, which has narrow bottoms partly covred with Small timber 2 or 3 men went out hunting, one of them killed a large beaver and an otter. Several of the horses chokd. by eating Some kind of a weed in this bottom, but they got over it after a while.—
Wednesday 30th. This was a cloudy morning, and we stayed here till about 11 o'clock to collect our horses, got two more; and have now altogether twenty-three horses. We then set out from Wal-la-wal-la river and nation; proceeded on about fourteen miles through an extensive plain, when we struck a branch of the Wal-lo-wal-la river, and halted for the night.  We saw no animals or birds of any kind, except two pheasants,  one of which Capt. Clarke killed. The whole of this plain is of a sandy surface and affords but thin grass, with some branches of shrubs which resemble sage or hyssop.  On the south side of this branch the soil is of earth and rich, covered with grass,  and very handsome. We are still accompanied by several of the natives.
