Saturday 26th. Last night Capt. Lewis and Capt. Clarke got each a horse, and we set out early, had a fine morning, and proceeded on very well, most of the men having their knapsacks carried on the horses. At noon we halted and took a little of our dried meat, which is the only food we have. At 2 o'clock we continued our journey, and the officers were obliged to go on foot again, to let some of the men ride whose feet were very sore. The country is level and has a most beautiful appearance. On the plains there is a species of clover,  as large as any I have seen, and has a large red handsome blossom. The leaves are not quite so large as those of the red clover cultivated in the Atlantic States, but has seven and eight leaves on a branch. We were overtaken and passed by a great number of the natives, with large droves of horses, that look well and are in good order. We travelled about 25 miles and encamped at a small grove of willows.
