Allan knew how to talk. Moreover, he had an interested listener in the officer, and that counted for a great deal. Besides, he felt deeply for the persecuted boy, and his heart was filled with a desire to assist him secure the legacy left by his father, than whom no living soul had ever gazed upon the hidden mine. Sheriff Bob listened to all that the boy said. Several times he scratched his head reflectively, and made a grimace, as though conflicting forces had begun to engage him in an inward war. And when finally Allan declared that he now knew all, the officer drew a long breath, and remarked, quietly: "I seem to smell a pretty good-sized rat about this game Mr. Artemus is putting up; but as I said, the warrant he swore out is in my hands for serving, and I just reckon I'll have to do my sworn duty and arrest this same Aleck----that is, if so be he shows up while we're around here." Allan looked him squarely in the eye; and he was sure one of the lids above the blue orbs of the official dropped a little in a suggestive way. He too drew a long breath, and with a smile on his boyish face, said as he arose: "Thank you, Mr. Sheriff, thank you very much!" CHAPTER XXII. THE GUARDIAN OF THE SILVER LODE. As has been mentioned before, Thad had a plan in view when he left the camp in company with Aleck, somewhere about midnight. Though for certain reasons which he considered good, he had not seen fit to take a single one of his comrades into his confidence, the scoutmaster believed that the only way for Aleck to win his own game was to find the long-lost mine, and take possession of the same in the name of his father, who had been the original discoverer of the lode. Scores of hungry prospectors, besides Kracker, had done everything in their power to locate the mine; though none had descended to his last unworthy methods of trying to torture Jerry Rawson's son, in the hope of profiting thereby. As the claim of the original discoverer rested only on a scant foundation, of course the man lucky enough to find the silver lode again would have a right to hold possession, in the eye of the law. He might choose to pay the widow something, but even that was a matter resting solely upon his conscience. Thad had a reason for carrying the only lantern belonging to the scouts; and he hoped that if they were so lucky as to find that Aleck's rude little chart told the truth, they might utilize that means of illumination when entering the mine. Of course both of them carried their guns, for there was no telling when they could return to camp. An arrangement had been with Allan, so that day and night there would be a sign shown, calculated to tell the absent ones whether the coast were clear, or the lawyer and sheriff still hovered near by, waiting to entrap the Rawson boy, should he show up. They had moved along for some time, when Aleck broke the silence by saying, with considerable feeling in his voice:
