"We soon got very much attached to each other, and wherever I went Bruce went too. He did not seem to take to any one else, and I was just as well pleased that he did not, for I never wanted him out of my sight. "That same summer a new hand was sent to the fort. He was an Englishman, who gave his name as Heathcote, and he brought with him a pure white female bull-dog that was one of the most dangerous-looking brutes I ever laid eyes on. She minded nobody but her master, of whom, to do her credit, she seemed fond enough. "I never much cared for that breed of dog, but I must say Vixen was about perfect in her way. As to good-breeding, there certainly wasn’t much to choose between her and Bruce. "I was a little uneasy as to how the two dogs would get on, and at first it did look as if there might be trouble, for Bruce, who utterly despised the rabble of curs hanging about the fort, evidently felt disposed to resent the coming of this possible rival; but almost before I knew it, the two were the best of friends, and would eat their dinner side by side like two well-behaved children. "After a while they took to going out a-hunting together, and grand times they had. They would work along in company until a herd of deer was started, and then Bruce would make for the fattest doe, his tremendous speed soon bringing him to her throat; while Vixen, following at her best rate, would come up just in time to help him to finish her, and then they would have a fine feast. "Once the dogs got into these ways neither Heathcote nor I had much more satisfaction out of them. They were never on hand when wanted. They kept growing wilder and wilder, and finally, toward autumn, they disappeared one day, and were never seen at the fort again. "We hunted for them high and low, sending out the half-breeds as far as Lake La Crosse on the east, and to the foot-hills of the Rockies on the west, but not a sign or trace could we find of them. When winter came and they did not return, we gave them up as lost, thinking that something must have happened to them on one of their hunting forays, or that perchance they had been killed by the Indians. "Two years went by, and Bruce and Vixen were almost forgotten, when stories began to reach the fort of a strange and fierce kind of wild dog that was being seen now and then by hunters and trappers in the out-of-the-way valleys and ravines of the foot-hills. "It was not an easy job to get at the bottom of these stories, for they passed from mouth to mouth before reaching us; but at last a trapper turned up who had seen a pack of the dogs himself, and after hearing his description I had no longer any doubt but that these wild dogs which were making such a stir were the offspring of our two former pets which had gone away in company.
