The chiefs having decided that camp should not be moved until the next day, Red Crow and his sister took me next morning up a stream now called Swift Water, running into the river from the west. There were a number of lakes upon it, and one of them, just above a falls, was a very beautiful sheet of water. Beyond it, at what was the head of the main fork of the stream, were more great deposits of ice, old Cold Maker's leavings. But I was not so much interested in them as I was in taking note of the beaver signs, which was a part of my duty on this trip of discovery into the southland. It was the factor's intention to send some _engagés_ trappers into it if I found enough fur to keep them busy. Between this lake and a smaller one lying at the foot of a great ice sheet, I found no less than thirteen dammed ponds, all containing a number of inhabited beaver houses; and there were a number of their ponds farther down the stream.
Camp was broken the following morning, but before the lodges came down I was off on the trail with the chiefs. We topped the long, high ridge sloping up eastward from the lower lake, and looked out upon the greatest expanse of mountain- and butte-studded plains that I had ever seen. And I thrilled at the thought that I was the very first one of my race to see it. Lone Walker pointed down to a small stream heading in a great patch of pine and spruce on the side of the ridge.
"That is the Little River. Far to the east it joins the Big River of the South," he told me, and I realized that I was on top of the watershed of the Gulf of Mexico. We rode on down to the stream and I got off my horse and drank from it for good luck. The whites misnamed it when they, years afterward, called it Milk River. The Blackfoot name was best, for it is a very small river for all its three hundred and more miles of length from its source to its junction with the Missouri.
As I drank the swamp-flavored water I thought how fine it would be to make a dugout there, and voyage down the stream to the Missouri, and down that to the Mississippi, and thence to the Gulf of Mexico and its tropical shores. What a long journey it would be; thousands of miles! What strange peoples I should see; tribe after tribe of Indians, then Americans, and at last the French and the Spanish of the Far South! And what adventure there would be! Fights with some of those wild tribes, and with bears, and perhaps with lawless whites. They would try to take from me the hundreds of beaver pelts that I should trap on the way! But no! My dugout would not carry many skins, and if I survived the dangers I should arrive, poor and ragged, among a strange people, and have to work for them for a few pence a day. "Away with you, dream," I said, and mounted my horse and rejoined the chiefs.
