It was a busy time for Ross, who promptly took Weston's place "rustling grub." But, as he worked, his thoughts wonderingly circled around Weston's strange actions. The fourth man was found and it was not Weston--yet Weston, it would appear, had believed himself to be the guilty party! It was too deep a puzzle for Ross. As the boy worked he kept a watchful eye on the trail for Leslie. Surely the latter would come down to Camp that morning and receive the word Ross had left him at the post-office. Steele, who had stayed behind long enough to examine the tunnel, confirmed Weimer's statement that more than enough work had been done to cover the requirements of the law. Weimer, jubilant, sat and talked to his old-time "pard," whose voice answered him, but whose satisfied gaze followed Ross. But it was to the man who had stood in the place of a father to him that Ross's eyes turned most frequently. Dr. Grant sat, appropriately, on the emergency chest, looking affectionately at his energetic nephew. Suddenly Ross picked up a tin cup full of water from the table, and held it out at arm's length toward his uncle. Dr. Grant smiled. "All right, Ross," he said quietly. Ross, Senior, looked from one to the other inquiringly. Ross, Junior, answered; but he turned his back on his father, and spoke hesitatingly. "I was showing uncle, father, that my hand is still steady enough to be the hand of a first class--surgeon." Promptly and heartily came the unexpected response from the elder Grant. "I'm glad of that, Ross, for I shall look to see you as successful in your profession as you have been in my business," and he turned at once to Weimer, and went on speaking. "Suppose," he was saying, "as long as you want to stay here, you get your friend"--he indicated the sheep-herder--"to come and live with you. I'm going to buy out Ross's interest in the shares, and I'll look to you to keep 'em in good shape--you and your friend--until we get a chance to sell well. Of course," he added carelessly, "I'll grub-stake you and more, both of you." Sheepy's eyes lighted, and Weimer grinned and slapped his knee. They were the only signs necessary to complete the bargain. After dinner, as Ross arose from the table, he saw Leslie hurrying down the trail. Ross went to meet him.
