Thursday, May 31st.—On arriving at Governor Stevens' tent I found that the Council had already met. After the usual preamble of smoking, Governor Stevens and General Palmer, in succession, made long speeches to them, explaining the benefits they would receive from signing this treaty, and the advantages which would result to them from their removal to the new lands offered in exchange for their present hunting grounds. The Council lasted till three o'clock.

This evening we went, as usual, to the Nez Percé camp. There was a foot-race, but the great events of the evening were the horse-races. Each of the tribes now here possesses large numbers of horses, so that wherever they are, the prairies about them are covered with these animals roaming at large until wanted by their masters. Part of these are derived from the wild horses of the prairies, while some, from the marks with which they are branded, show that they have been stolen from the Spaniards in Upper Mexico. To capture horses is esteemed next in honor to laurels gained in actual war, and they will follow the party of a hostile tribe for weeks, watching an opportunity to "run off" their horses. It is for this, too, that they are hovering around the emigrants on the plains, who some times by a stampede, or a single bold dash, lose in a night all their animals, and are left helpless on the plains, as a ship at sea without sails.

Living as they do on horseback, racing forms one of their greatest amusements. They will ride for miles, often having heavy bets depending on the result. On this occasion we saw nearly thirty Indians start at once and dash over the plain like the winds, sweeping round in a circle of several miles.

Friday, June 1st.—The Council did not meet this morning, as the Indians wished time to consider the proposal made to them during the last few days. We learned that two or three of the half-civilized Nez Percés, who could write, were keeping a minute account of all that transpired at these meetings.

At the races this evening a serious accident took place, and which had nearly proved fatal. The Indians, as usual, were dashing about on horseback, some going up and others down, when two of them came in collision, knocking down both horses and leaving the riders senseless. No bones happened to be broken: the "medicine men" took charge of them, and it is supposed they will recover.

To-day has been the warmest we have had: there has not been a breath of air stirring, and the valley seemed like an extensive oven. At evening, however, the skies darkened, and for two hours we had the most tremendous thunder storm I ever witnessed. It was worthy of the tropics.

Saturday, June 2d.—Just before I was up this morning we had a call from some of the Indians, who pay little regard to visiting hours. After breakfast I rode over to see the gentlemen at the old Mission, and on my return to camp found that the Council was already assembled, having met at twelve o'clock. The Indian Chiefs had at length begun to reply, so that another step has been gained. After Governor Stevens' opening speech, several of them followed in short addresses. I arrived there just in time to hear the last one, made by one of the Cayuse Chiefs. He did not commit himself as to what they would do, but the whole tenor of his address was unfavorable to the reception of the treaty. After a few words in conclusion from Governor Stevens, the Council adjourned until ten o'clock on Monday.

Then came part of my daily routine of amusement, to ride out and see Lieutenant Gracie practice the soldiers at target firing. He has been gradually lengthening the distance, and some of the men are now able to make very admirable shots. At the Indian camp to-night there was a great foot-race between about a dozen competitors, who ran over two miles. It was a good test of the long-winded endurance of the young warriors. As they raced off over the plain, parties of the Indians and those of us who were on horseback, rode on each side of them, the friends of the competitors encouraging them and taunting those who flagged.

Sunday, June 3d.—A quiet day, most of it spent in reading in my tent. In the afternoon rode over to the Mission, and on my return dined with Governor Stevens. This evening the pack mules from Fort Dalles, with seven days' provisions, arrived at the Mission and are to be brought over early to-morrow morning by some of the soldiers.

Monday, June 4th—Breakfast at the fashionable hour of ten, as I was waiting for Lieutenant Gracie, who was obliged to go early to the Mission to see about the pack mules. An express came in this morning from the Dalles, giving him orders to join Major Haller's command, forty-five miles below this place, as soon as the Council breaks up.
