The Colonel, who had been having a fine time with the impatient and curious hounds, did not vouchsafe any information on that score. But very shortly we were destined to learn the use of this incongruous firearm. I was riding in advance of Wallace, and a little behind Jones. The dogs—excepting Jude, who had been kicked and lamed—were ranging along before their master. Suddenly, right before me, I saw an immense jack-rabbit; and just then Moze and Don caught sight of it. In fact, Moze bumped his blunt nose into the rabbit. When it leaped into scared action, Moze yelped, and Don followed suit. Then they were after it in wild, clamoring pursuit. Jones let out the stentorian blast, now becoming familiar, and spurred after them. He reached over, pulled the shotgun out of the holster and fired both barrels at the jumping dogs. I expressed my amazement in strong language, and Wallace whistled. Don came sneaking back with his tail between his legs, and Moze, who had cowered as if stung, circled round ahead of us. Jones finally succeeded in getting him back. "Come in hyah! You measly rabbit dogs! What do you mean chasing off that way? We're after lions. Lions! understand?" Don looked thoroughly convinced of his error, but Moze, being more thick-headed, appeared mystified rather than hurt or frightened. "What size shot do you use?" I asked. "Number ten. They don't hurt much at seventy five yards," replied our leader. "I use them as sort of a long arm. You see, the dogs must be made to know what we're after. Ordinary means would never do in a case like this. My idea is to break them of coyotes, wolves and deer, and when we cross a lion trail, let them go. I'll teach them sooner than you'd think. Only we must get where we can see what they're trailing. Then I can tell whether to call then back or not." The sun was gilding the rim of the desert rampart when we began the ascent of the foothills of Buckskin. A steep trail wound zigzag up the mountain We led our horses, as it was a long, hard climb. From time to time, as I stopped to catch my breath I gazed away across the growing void to the gorgeous Pink Cliffs, far above and beyond the red wall which had seemed so high, and then out toward the desert. The irregular ragged crack in the plain, apparently only a thread of broken ground, was the Grand Cañon. How unutterably remote, wild, grand was that world of red and brown, of purple pall, of vague outline!
