As if he understood it all, the horse of his own accord struck into a brisk gallop, which rendered unnecessary any other protection from the cold. The snow was still falling, but the temperature was not low, and there was not enough on the ground to interfere with the travelling of the animal, who maintained his pace until the abrupt appearance of the rocky section, with its trees and bowlders, compelled him to drop to a slow walk, with his nose thrust forward, as if to scent every step of the way, like an elephant crossing a doubtful bridge. "Here we are, my boy!" called out Warren, "and you couldn't have come more truly if the sun had been shining." It certainly was a marvellous piece of woodcraft, if such it may be called, on the part of the pony, that he should have struck the spot so accurately, and yet it is scarcely less marvellous that, had he needed direction, his master was competent to give it, despite the darkness and the snow. Warren left the saddle for the last time. With no stars or moon in the sky, and with the snow falling faster than ever, it would seem that one's eyes were of little use, but they served their purpose well in the present instance. Paying no heed to the animal, he bent over, groping his way among the rocks, which began abruptly on the edge of the prairie, and had not spent five minutes thus when he came upon that for which he was looking--an opening between a mass of bowlders, along which a person or animal could make his way with little difficulty. "Here we are, Jack, my boy! Come on; we'll soon reach our house." With more thrusting forward of the head, and sniffing of the air, the pony obeyed, though it is hardly to be supposed that he understood all that was said to him. On the previous winter, when Warren Starr and Tim Brophy were hunting in this section, they found game so abundant that they decided to spend two or three days in the neighborhood. Accordingly they put up a shelter which afforded good protection at night, and would do the same against any storm not too violent. A rock a dozen feet in length formed a half-circle, the upper edge projecting over to the extent of a yard or more. All that was required was to lean a number of branches against this, the upper parts supported by the ledge, while the lower rested on the ground, some eight or ten feet away from the base. These branches being numerous and thickly placed, constituted what might be considered a tepee, with only the broad opening in front. It was in this rude shelter that Warren Starr and Tim Brophy had spent a couple of nights in comparative comfort. The second one was bitterly cold, and they kindled a fire near the entrance. The smoke caused some trouble, but wrapped in their thick blankets, and stretched out back to back, they slept as soundly as if in their beds at home.
