For several days after Billy Cody got his prize he did nothing but train the animal to his use and was delighted to find that Little Grey would follow him like a dog wherever he went.
Having all arranged now for his wild horse hunting, he set out one day from home to be gone a week or more, he told his mother, and with the promise that he would bring her a small fortune soon.
He had already discovered the feeding grounds of the herd, and thither he went at once, arriving in the vicinity shortly before dark.
As he had expected, he found the herd, nearly five hundred in number, but he kept out of sight of them, as it was so near dark, and camped until morning, when he found they had gone up the valley for some miles.
Cautiously he followed them, and getting near unobserved at last made a dash upon them.
Into their midst he went and a good horse was picked out and lariated in the twinkling of an eye and quickly hoppled and turned loose.
Then another and another, until Billy felt that he had done a pretty good day's work.
He had discovered two things, however, and that was that Little Grey seemed more than a match for any of the herd with one exception, and that one was a large, gaunt-bodied black stallion, that appeared to drop him behind without much effort.
"I've got to have him," said Billy, as he returned to his hoppled prizes and began to drive them toward the fort.
It was a long and tedious work, but the boy was not impatient and reached the fort at last and received his reward, which he at once carried to his mother and received her warm congratulations upon his first success.
