After passing St. Charles, Missouri, the ranches of the settlers were farther and farther apart, and in a few days we saw the last of them and were in the wild country. Game now became more and more frequent, especially white-tail deer, of which we soon had some for the table. The boat was always tied to an island or to the shore at sundown, and during the short remainder of daylight we would all scatter in the near timber to hunt. A number of wild turkeys were killed, which made us some fine feasts. On these occasions, however, I was only a follower of the hunters. My red-letter day was yet to come.

At Fort Pierre we saw a great number of Sioux Indians. Formerly a company post, it had been sold to the United States, and was now occupied by several companies of soldiers. Two days after leaving the fort, we sighted the first of the buffalo herds, a small band of bulls that splashed out of the river not far ahead of the boat, and took to the hills. About four o'clock that afternoon, the port engine breaking down, we had to make a long stop for repairs. As soon as we swung into the bank and learned that the boat would be tied there for the night, my uncle got out his rifle, and we went hunting.

The timber bordering the river was half a mile wide, with an undergrowth of willow- and rose-brush so thick that we never could have penetrated it but for the game trails crossing it in every direction. From the looks of them, I thought that thousands of animals must be living there. The trails were worn deep by their sharp hoofs.

In places the earth was moist but hard, and there the tracks were plainly outlined. My uncle pointed out the difference in them—how the tracks of the deer differed from those of elk, and how these differed again from the tracks of the buffalo. I was taught, too, that wolf tracks were longer than those of the mountain-lion, which were nearly circular. Finally, I was asked to prove my knowledge.

"What made those tracks?" I was asked.

I hesitated a moment, and replied that I thought buffalo had made them.

"Right," said my uncle. "They seem very fresh; we will follow them."

The myriad tracks of different game, the mystery of the deep woods, the thought that hostile Indians might be there hunting us, all combined to excite me. My heart thumped rapidly and I found it difficult to breathe. I was afraid, and kept looking intently in all directions—even behind me, for I expected every moment to see something come charging through the brush, either to rend us with sharp claws or to stick our bodies full of arrows.

But nothing could have induced me to admit that I felt so; gritting my teeth, I followed on uncertain legs, close at Uncle Wesley's heels. So close was I that when he suddenly stopped, I bumped into him, and then gave a little squeal of fright, for I thought that he had discovered something to justify my fears.

"Sh-h-h-h!" he cautioned, and reaching back and drawing me to his side, he pointed significantly ahead.
