At early morn, having provided himself with a bow and a quiver full of arrows, without informing any one of his plan he stole out of camp, and, running at full speed, crossed the nearest mountain to the East.

Allowing himself little time for rest, pushing forward by day and night, and after fording many of the smaller mountain-streams, on the evening of the third day of his travel he came upon what he believed to be a well-traveled road. But—how strange!—there were two endless iron rails lying side by side upon the ground. Such a curious sight he had never beheld. There were also large poles, with glass caps, and connected by wire, standing along the roadside. What could all this mean?

Poor Little Moccasin's brain became so bewildered that he hardly noticed the approach of a freight-train drawn by the "Thundering Horse."

There was a shrill, long-drawn whistle, and immense clouds of black smoke; and the Thundering Horse was sniffing and snorting at a great rate, emitting from its nostrils large streams of steaming vapor. Besides all this, the earth, in the neighborhood of where Little Moccasin stood, shook and trembled as if in great fear; and to him the terrible noises the horse made were perfectly appalling.

Gradually the snorts, and the puffing, and the terrible noise lessened, until, all at once, they entirely ceased. The train had come to a stand-still at a watering tank, where the Thundering Horse was given its drink.

The rear car, or "House on Wheels," as old Black Pipe had called it, stood in close proximity to Little Moccasin,—who, in his bewilderment and fright at the sight of these strange moving houses, had been unable to move a step.

But as no harm had come to him from the terrible monster, Moccasin's heart, which had sunk down to the region of his toes, began to rise again; and the curiosity inherent in every Indian boy mastered fear.

He moved up, and down, and around the great House on Wheels; then he touched it in many places, first with the tip-end of one finger, and finally with both hands. If he could only detach a small piece from the house to take back to camp with him as a trophy and as a proof of his daring achievement! But it was too solid, and all made of heavy wood and iron.

At the rear end of the train there was a ladder, which the now brave Little Moccasin ascended with the quickness of a squirrel to see what there was on top.

It was gradually growing dark, and suddenly he saw (as he really believed) the full moon approaching him. He did not know that it was the headlight of a locomotive coming from the opposite direction.
