"Of course," was the reply; "buffaloes were far more numerous then than now, and sometimes the herds were so large that it took an entire day, or even longer, for one of them to cross the road. Twice we were unable to go on because the buffaloes were in the way, and so all of us who had rifles went out for a hunt. I was one of the lucky ones, and we went on in a party of four. Creeping along behind a ridge of earth, we managed to get near two buffaloes that were slightly separated from the rest of the herd. We spread out, and agreed that, at a given signal from the foremost man, we were to fire together--two at one buffalo and two at the other. We fired as we had agreed. One buffalo fell with a severe wound, and was soon finished with a bullet through his heart; the other turned and ran upon us, and, as I was the first man he saw, he ran at me. Just then I remembered that I had forgotten something at the camp, and, as I wanted it at once, I started back for it as fast as I could go. It was a sharp race between the buffalo and me, and, as he had twice as many legs as I could count, he made the best speed. I could hear his heavy breathing close behind me, and his footsteps, as he galloped along, sounded as though somebody were pounding the ground with a large hammer. Just as I began to think he would soon have me on his horns, I heard the report of a rifle at one side. Then the buffalo stumbled and fell, and I ventured to look around. One of the men from camp had fired just in time to save me from a very unpleasant predicament, and I concluded I didn't want any more buffalo-hunting for that day." Hardly had the Doctor finished his story when there was a long whistle from the locomotive, followed by several short ones. The speed of the train was slackened, and, while the passengers were wondering what was the matter, the conductor came into the car where our friends were seated and told them there was a herd of buffaloes crossing the track. "We shall run slowly through the herd," the conductor explained, "and you will have a good chance to see the buffalo at home." [Illustration: HERD OF BUFFALOES MOVING.] They opened the windows and looked out. Sure enough, the plain was covered, away to the south, with a dark expanse like a forest, but, unlike a forest, it appeared to be in motion. Very soon it was apparent that what seemed to be a forest was a herd of animals. [Illustration: AN OLD SETTLER.]
