Tad had scrambled to his feet. Ned followed his lead, and together they began climbing the steep side of the mountain, bearing off to the right towards a gap in the ridge, rather than climbing straight towards the top. All the time Butler was keeping a sharp lookout for trail marks, but he found nothing that would aid him in his quest. He was positive that the collie had been killed by the prowler whom he had scared away from the camp on the previous night.

"Who do you think it was, Tad?" questioned the other boy after a long, hard climb.

"If I were to guess I should say it was the same old trouble-maker, Stillman, or Batts, his assistant, or companion-in-crime, whichever you may wish to call it."

"Well, I must say those fellows are bold."

"They probably have a good deal at stake," answered Tad.

"What do you mean by that?"

"That there is crooked business of some kind going on up on this ridge. I don't suppose it is any of our affair, except possibly as it interferes with us and our rights."

"We've a large-sized bone to pick with the man anyway."

"We have," agreed Tad. "Here is a ledge that we can walk on. Keep a sharp eye down in the gulch below and look out that you don't fall. Shall I pass the rope around you?"

"No. What do you think I am, a baby? I don't get dizzy so easily as all that."
