The black would trot off quite calmly and in a most matter of fact way, as though to shame all slanderers of his lamb-like character. Then, as the bystanders would turn away, he would utter a squeal, throw down his head, and go at it. He was a very hard bucker, and made some really spectacular jumps, but the trick on which he based his claims to originality consisted in standing on his hind legs at so perilous an approach to the perpendicular that his rider would conclude he was about to fall backwards, and then suddenly springing forward in a series of stiff-legged bucks. The first manoeuvre induced the rider to loosen his seat in order to be ready to jump from under, and the second threw him before he could regain his grip. "And they say a horse don't think!" exclaimed an admirer. But as these were broken horses--save the mark!--the show was all over after each had had his little fling. We mounted and rode away, just as the mountain peaks to the west caught the rays of a sun we should not enjoy for a good half hour yet. I had five horses in my string, and this morning rode "that C S horse, Brown Jug." Brown Jug was a powerful and well-built animal, about fourteen two in height, and possessed of a vast enthusiasm for cow-work. As the morning was frosty, he felt good. At the gate of the water corral we separated into two groups. The smaller, under the direction of Jed Parker, was to drive the mesquite in the wide flats. The rest of us, under the command of Homer, the round-up captain, were to sweep the country even as far as the base of the foothills near Mount Graham. Accordingly we put our horses to the full gallop. Mile after mile we thundered along at a brisk rate of speed. Sometimes we dodged in and out among the mesquite bushes, alternately separating and coming together again; sometimes we swept over grassy plains apparently of illimitable extent, sometimes we skipped and hopped and buck-jumped through and over little gullies, barrancas, and other sorts of malpais--but always without drawing rein. The men rode easily, with no thought to the way nor care for the footing. The air came back sharp against our faces. The warm blood stirred by the rush flowed more rapidly. We experienced a delightful glow. Of the morning cold only the very tips of our fingers and the ends of our noses retained a remnant. Already the sun was shining low and level across the plains. The shadows of the canons modelled the hitherto flat surfaces of the mountains.
