"I will that," returned the Kentucky boy, impressed by his chum's earnestness.
After a little while Frank came back again. His manner told that he was quite satisfied with what he had done.
"A sharp-eyed trailer might find where we left the canyon," he admitted; "but I don't believe any ordinary fellow would notice the marks. So I think our horses stand a first class chance of being here when we come back for 'em."
Bob got on his feet.
"I've fixed up some grub, just as you told me," he remarked. "It isn't much, but ought to serve in a pinch."
"And as it's nearly noon now," observed Frank. "Why not take a snack before we leave our base of supplies? Let's get the stuff out of the cache again, and have a round of bites."
"I don't see the use of hurrying away from here right now, anyhow," Bob remarked, while they were eating.
"You mean," said Frank, "that we only came here to see what we could find out about the secret of old Thunder Mountain, and why it kicks up such a rumpus every little while?"
"Yes, and seems to me that since we're right on the ground now, we might just as well start business, here," Bob asserted.
"That is, hang around until night, and wait to see if the grinding begins again, as it did when we were in camp below?"
