"I don't know much about it. I'm thinkin', however, that if they are to be found, the Navajo will be as likely to find 'em as anybody."

"I wish I never had started on this trip!" exclaimed Fred manifestly downcast at the outlook.

"It doesn't make any difference what you 'wish'," said Zeke gruffly. "You have started and you're here. I don't know of any way of gettin' out of Thorn's Gulch outside of flyin' or walkin'."

"I guess you're right," replied Fred dolefully. "Hello, what's that?" he added abruptly. From far away had come a faint shout. Fred was positive that he had heard a call, but Zeke, ignoring the words of the Go Ahead boy, abruptly arose and ran to a place far to the left of the camp.

His startling action when it was seen by the Go Ahead boys at once caused every one to follow his example.

Again the faint call was heard and this time it was answered abruptly by Thomas Jefferson, whose voice carried far and was almost as sharp as the report of a pistol.

"Who is it? Who is it?" demanded Fred.

The Indian made no reply, but as the distant call was heard again he repeated his call, which this time was distinctly answered. As yet no one was able to see the place from which the cry had come.

"Do you think anyone is in trouble?" inquired Grant anxiously of the guide.

"No," replied Zeke.
