, 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.

Absorbed in this new and glorious sight, he did not notice the starting
of his own car, until it was too late, for, while the car moved, he
dared not let go his hold upon the brake-wheel.

There he was, being carried with lightning speed into a far-off, unknown
country, over bridges, by the sides of deep ravines, and along the
slopes of steep mountains.

But the Thundering Horse never tired nor grew thirsty again during the
entire night.

At last, soon after the break of day, there came the same shrill whistle
which had frightened him so much on the previous day; and, soon after,
the train stopped at Miles City.

But, unfortunately for our little hero, there were a great many white
people in sight; and he was compelled to lie flat upon the roof of his
car, in order to escape notice. He had heard so much of the cruelty of
the white men that he dared not trust himself among them.

Soon they started again, and Little Moccasin was compelled to proceed on
his involuntary journey, which took him away from home and into unknown
dangers.

At noon, the cars stopped on the open prairie to let Thundering Horse
drink again. Quickly, and without being detected by any of the trainmen,
he dropped to the ground from his high and perilous position. Then the
train left him--all alone in an unknown country.

Alone? Not exactly; for, within a few minutes, half-a-dozen Crow
Indians, mounted on swift ponies, are by his side, and are lashing him
with whips and lassoes.

He has fallen into the hands of the deadliest enemies of his tribe, and
has been recognized by the cut of his hair and the s
