It was one day early in the autumn that Leloo's father sent him down the trail some ten or fifteen miles with a message to the "boss" of the great railway construction camp that the Lillooet Indians would supply fifty men to work on the Company's roadway. So the boy mounted his pet cayuse and started off early, swinging down the mountain trails into the canyons, then climbing again across the summit, with its dense growth of timber. His little legs were almost too short to grip his horse's middle as his father could have done, so he went more slowly and carefully over the dangerous places, marking every one in his mind, in case he was late in returning. When he reached the camp the "boss" was absent, and, Indian-like, he would deliver his message to no one else except the man it was intended for, and when the "boss" returned at supper time from far down the grade, he insisted upon Leloo sharing his pork and beans and drinking great quantities of tea. "Better stay all night, youngster," said the boss kindly; "It's a long ride back, and it's going to be dark." "No stay to-night," answered Leloo. "Maybe some time I stay, but no to-night." "Well, you know best, kid," replied the boss. "There's one thing--no harm will ever come to an Indian boy on a mountain trail. But be careful; the canyons are deep, and the trail is bad in spots." "Me know, me careful," smiled Leloo, and mounting his cayuse, trotted off gayly, just as the sun was lost behind a grim, rocky peak in the west. But the "boss" was right: night comes quickly in the mountains, and this night was unusually dark. Leloo had to ride very slowly, for the narrow trail was a mere ledge carved out from the perpendicular walls of the cliffs, which arose on the left, a sheer precipice hundreds of feet above him, and fell away to the right in a yawning chasm, black, and deep and unexplored. But the sure-footed cayuse stepped gingerly and knowingly, neither halting nor stumbling, and his wise little rider let the animal pick its own way, knowing well that a horse's senses in the dark are more acute than a human's. Presently from far across the canyon arose a weird, prolonged howl. Then from the heights above came an answering one. "Ah, my brothers!" called Leloo aloud. "You have come to greet me through the night," and his eyes lighted like twin black fires, for he loved these wolves that made their dens and lairs along the Cariboo Trail, and to-night they were to serve him in the oddest fashion that a wild animal was ever called upon to do. As he rode on, he would--just for company's sake--call back to the wolves, answering their cries with such a perfect imitation of their wild voices that they would reply to him, from far below, then again from far above, and Leloo would smile to himself and say, "That is right, O great and fierce Leloos; answer me, for you are my kin and my cousins."
