"Guess heap, can't tell," Injun replied. "Henry Dorgan, him leave Monday," Injun added darkly, plainly willing to connect the man he disliked with the theft.

Whitey hardly thought that Dorgan would risk a return to the ranch for Monty, though he always had admired the pony. If Dorgan had stolen Monty, it was pleasant to think that he was now wending his way across the plains on foot.

Another idea occurred to Whitey. "Why don't you stay with me, Injun?" he demanded. "Then we can ride back to the Bar O together."

Injun grinned his agreement to the idea, not saying that he had thought of it first. So Whitey transferred his person to Monty, and, leading the Star Circle horse, he and Injun and Hank Dawes continued on their way. And Mr. Dawes was allowed to ride ahead while Whitey told Injun what had befallen him since leaving the Bar O Ranch, and of his present errand.

Injun cast a knowing eye at the sky. "No cut out cows t'day," he said. "Heap storm comin'."

"What's the difference?" Whitey asked. "Maybe we can ride night herd. It'll be great fun."

Riding night herd was not Injun's idea of fun, but he was so glad to be with Whitey again that he made no objection. He seldom made objections, anyway. It occurred to neither of the boys that after Injun's long pursuit of the horse-thief, it would be a hardship for him to ride all that day and possibly that night. And, of course, Injun wasn't hungry. He had not been fool enough to start out on a long chase without providing himself with food.

So the boys rode on. Even had they known into what they were riding it is unlikely that they would have turned back. Had Walt Lampson known of the coming peril he would not have been at the Star Circle, laughingly telling his men of sending Whitey on a wild-goose chase, that would end with his spending a night in the saddle, facing a blinding storm. Lampson and all the men he could summon would have been heavily armed, dashing at full speed toward the threatened herd.

Buck Milton, the range boss, made a better impression on Whitey than any other man he had seen at the Star Circle. He was tall, blond, sinewy. He was thoughtful and serious, and not ill-natured. He looked like a man who could take a joke which he might not understand any too well, and put up a fight in which he would prove a deadly factor. In short, he was a character you would look at twice, and Whitey was surprised to find him in the Star Circle outfit.
