"Bob Owens," said he in a low tone as they resumed the march, "you've got another chance to put a feather in your hat—a big one, too. Lieutenant Earle will never rescue Mr. Wentworth's boys, but you can if you're smart."

Bob, who always listened in the greatest amazement (and with some incredulity, too, it must be confessed) to his friend's predictions, could only look the surprise he felt. How any one, by simply looking at a pony's track, could tell what a party of men whom he had never seen were going to do, he could not understand.

"To begin with," continued George, "our Indians expected to have an addition made to their party, and they expected also that it would be made just where it was made. How do I know that? By the looks of things. The ponies were all huddled together in one place, and they must have stood there a good while, judging by the stamping they did. Their riders must have dismounted there, for I saw the prints of their moccasins in the sand. I noticed also that the side of the nearest sandhill had been disturbed, and that told me that one of their number had climbed up there to watch for the expected warrior."

"Perhaps he was watching for us," suggested Bob.

"If he was, he wouldn't have watched for us with his feet, would he?" demanded George.

"'With his feet'?" echoed Bob.

"Yes. He would have been more likely to watch for us with his eyes."

"How do you know that he didn't?"

"Because he climbed up on our side of the hill, and that would have exposed his whole body to our view if we had been anywhere within sight of him. His eyes were turned the other way; that is, in Lieutenant Earle's direction. He wasn't afraid of being seen by us, but he took all due precautions to conceal himself from the gaze of any one who might happen to come that way from Lieutenant Earle's command; for near the place where the ponies were standing I saw the tufts of grass he had pulled up to tie around his head."

"Well, I am beat!" exclaimed Bob.
