After they had ridden some distance, Frank proposed that they halt for the night.

“We are in for an open-air camp to-night,” he said. “It is something we did not expect, but it can’t be helped, and as the night is not cold I think we can get along all right. We need rest, too.”

“That’s right,” agreed Bruce. “I feel as if I need about a week of steady resting, but I don’t care to take it here.”

“How about the Indians?” asked Jack. “We are not very far from them, and they might find us.”

“I scarcely think there is any danger of that.”

“Why not?”

“Those redskins were so badly frightened that they’ll not go hunting after white boys to-night. It is more likely they will skin out and make for the Shoshone Reservation, on which they must belong.”

“But what if they should happen to follow us?” Jack persisted.

“We must take turns at standing guard to-night, and the guard should be able to give us warning of danger in time for us to mount our wheels and get away.”

It was plain that Diamond was not in favor of stopping there, but he said no more.
