Several of the natives followed us.   went about eight miles without water and halted at a large Spring branch [ Possibly Carmen Creek] to let our horses feed and dine ourselves. Some pitch pine on the mountains which make near the River on each Side.  the River bottoms narrow and verry much dryed up.  the Soil verry indifferent.  we proceeded on over a level Smooth plain abt. 7 miles  then passed the end of a mountain near the River where the Stone lay one on an other & holes So that the horses could Scarsely git along without breaking their legs.  we then proceeded on to a large Creek [Tower Creek] which falls in on the East Side of the River.  we took a path up Sd.

They all came down to our camp, and we proceeded on with 27 horses and one mule. Our old guide after consulting with the rest of the Indians, thought it was better to go along the north side of the Columbia, then on the south side. We therefore proceeded down, the same way Captain Clarke had been before, 30 miles, and then turned up a creek that comes in from the north [Boyles Creek], and encamped on it about 3 miles and an half from the mouth. Two hunters had gone on ahead this morning, and at night joined us, having killed one deer. The first cost of the articles, which had been given for each horse, did not amount to more than from three to five dollars; so that the whole of them only cost about one hundred dollars.

We had a fine morning, & set out early, and proceeded on about 2 miles, and passed several Indian lodges, and met with some Snake Indians, from whom we purchased for trifles a number of fine Salmon, the Natives have Wares fixed across the Columbia River, in which they catch more or less of them every night--.   A strange Indian came in sight of the lodges, which we past; which the Snake Indians thought was one of the Nation of Indians, which they called the flatt head nation:--   he ran as soon as he saw us; and several of the Snake Indians followed him, We proceeded on a short distance, and crossed the Columbia River, where we halted to break fast.  One of our party was sent out this morning a hunting, and two others of our party was sent to the Indian Camp with some articles to purchase some Salmon,-- but the Indians had removed their Camps, & they got none.   We proceeded on our way, and crossed over some rough hills, some of them very steep, & passed through some deep Vallies, which had white earth in them, which was occasioned by the Earth being washed down from the Hills of that Collour.--

We went about eight miles & halted to rest our horses & to dine, where some of the Natives followed us.   We saw some Pitch pine trees which grew on the Mountains which make near to the River on each side of it.   We proceeded on & passed through a smooth plain about 7 Miles & along the side of a mountain; which lay near the River, where the Stones lay very pleanty, & the place full of holes, & where we found it almost impossible, for our horses to pass, without breaking their legs.   We passed along the Edge of this mountain with great difficulty, & came to a large Creek, which falls in, on the East side of the Columbia River; we proceeded up this creek, & found plenty of wild or choak cherries and service berries.   One of our hunters killed a Deer on the Edge of the Mountain, which we had passed & which he brought to us in the evening; We came 15 Miles this day, & encamped on the Creek, where we found several Indian lodges, which we slept in
