"But I don't see how that proves they went before. They may have left after the other man."

The Navajo shook his head, however, and said, "They go first."

"What are we to do now?" demanded George as he joined his companions.

"The first thing we want is some breakfast and then we'll decide what next to do," said Grant, who in spite of Fred's greater readiness to talk, now naturally assumed the place of the leader of the three Go Ahead Boys.

At that moment, however, the Navajo again turned to the young campers and said, "I'll go to find out where Zeke and the two men went. If I go you three boys must stay here until I come back."

"But suppose you don't come back?" suggested Fred.

"I shall come," said the Navajo confidently.

"But suppose you don't?" said Fred again.

"If I do not come by to-morrow morning," explained Thomas Jefferson, "then you will know that something has happened to me and you will go back if you can find your way."

"Not much!" declared Fred. "If you don't come we shall try to find out what has happened to you."
