She reasoned in circles, as the best of us will when trying to justify doubtful acts; but she traveled in a straight line when she picked up Wunpost's trail and followed him over the rocks. He had ridden out in the night, turning straight up the ridge where the mountain-sheep trail came down; and Good Luck bounded ahead of her, his nose to the ground, his bobbed tail working like mad. There was a dew on the ground, for the nights had turned cold and, though he was no hound, Good Luck could follow the scent, which was only a few hours old. Wunpost had slept till after midnight and then silently departed, taking only Old Walker and his mate; and the trail of their sharp-shod shoes was easily discernible except where they went over smooth rocks. It was here that Wunpost circled, to throw off possible pursuit; but busy little Good Luck was frantic to come up to him, and he smelled out the tracks and led on. Wunpost had traveled in the night, and, after circling a few times, his trail straightened out and fell into a dim path which had been traversed by mules once before. Up and up it led, until Tellurium was exhausted and Wilhelmina had to get off and walk; and at last, when it was almost at the summit of the range, it entered a great stone patch and was lost. But the stone-patch was not limitless, and Wilhelmina was determined--she rode out around it, and soon Good Luck dropped his nose and set out straight to the south. To the south! That would take him into the canyon above Blackwater, where the pocket-miners had their claims; but surely the great Sockdolager was not over there, for the district had been worked for years. Wilhelmina's heart stopped as she looked out the country from the high ridge beyond the stone-patch--could it be that his mine was close? Was it possible that his great strike was right there at their door while they had been searching for it clear across Death Valley? It was like the crafty Wunpost always to head north when his mine was hidden safely to the south; and yet how had it escaped the eyes of the prospectors who had been combing the hills for months? Where was it possible for a mine to be hid in all that expanse of peaks? She sat down on the summit and considered.
