"Absolutely, we shall pay it, if I have to beg robes and beaver skins from my people to make up the amount!" Tsistsaki declared. Looking back at it after all these years, I see that the dissolution of the American Fur Company was an historical event. Its founders and its later owners, the Chouteaus, had been the first to profit by the discoveries of the Lewis and Clark expedition, and year by year they had built a string of trading-posts along the Missouri, which did an enormous business in trading with the various tribes of Indians for their buffalo robes and beaver and other furs. But little by little the richness and vastness of the Missouri River country became known to the outside world; first came various opposition fur-traders, then settlers upon the rich bottom lands of the river. Before the settlers the Indians and the buffaloes fled, and the income of the company correspondingly decreased. The Chouteaus simply could not brook opposition, or trade with penny-saving settlers, profitable as that might have been; so in this year of 1865 they went out of business. At the time only two of the company posts, Fort Union, at the mouth of the Yellowstone, and Fort Benton were in what may be termed still virgin country; that is, country still rich in buffaloes and fur animals and controlled by various powerful tribes of Indians. It was fear of the Indians that kept the settlers back. We were to embark for the mouth of the Musselshell upon the next steamboat that arrived, and my uncle was very busy getting together our necessary equipment and engaging the help that we should need. I helped him as much as I could, but found time to ride over to the camp on the Teton and ask Pitamakan to go down-river with us. His father objected to his going, on the ground that he was needed in camp to herd the large band of horses that belonged to the family, and in which I had then about forty head, my very own horses. But finally a youth was found to take his place, and Pitamakan was free to come with us. On the last day of May the second steamboat of the season tied up at the river-bank in front of the fort, and in the afternoon of the following day we went aboard it with our outfit and were off upon our new adventure. The outfit comprised ten engagés, all of them with their wives, women of the Pikuni, several of whom had children; six work-horses and two heavy wagons; three ordinary saddle-horses, property of the engagés, and three fast buffalo-runners, one of which was Is-spai-u, the Spaniard, the most noted, the most valuable buffalo-horse in all the Northwest; eleven Indian lodges, one to each family; tools of all kinds; some provisions; a six-pounder cannon with a few balls and plenty of grapeshot; and of course our own personal weapons.
