"A cow-puncher can't live without dust," returned Jerry, whose face was covered with a gray mask, through which his eyes shone in strong contrast. "My teeth is worn down and my lungs coated with it, but I don't mind it no more. Look out for that cow there!"

An old cow, made angry and brave at once by an apparent menace to her calf, was charging down on John full tilt—tail up, head down, eyes rolling—vengeance in every motion; for a minute it looked as if he would be run down: the charging beast was going at such speed that she would be hard to avoid; but when she was within five feet of the boy's horse he gave a quick pull on the rein, a sharp jab with his spurs, and the clever little cow-pony wheeled sharply round and out of range, the old cow lumbering harmlessly by, her own weight and impetus preventing her from turning.

"You want to keep your eye out for those old cows with calves," admonished Jerry, "they're looking for trouble."

All hands were now busy keeping the great herd together, single animals were constantly breaking out and had to be driven back; sometimes several would start at once, when there would be some pretty sharp riding for a while.

It was about midday, the sun was blazing down from above, the dust rose in clouds from below, lining mouths and nostrils of the riders. Since six o'clock they had been in the saddle constantly, and all felt, as Jerry expressed it, "Plumb empty and bone dry."

The herd presently quieted down somewhat and allowed the men to eat in relays, some watching while others fed. It was the briefest kind of a meal, but it sufficed, and in a half hour every man was ready, mounted on a fresh horse, for the real work of the day—"cutting out."

John and Jerry approached the tumultuous herd, a swirling restless sea of backs and horns. The din was tremendous; every cow lowed to her calf and every calf to its mother; the tread of thousands of hoofs even on the soft earth caused a heavy, rumbling sound that filled the air, and above all was the sharp rattle of one horn against another, of a thousand horns against each other. Into this seething mass of living wild creatures armed with sharp horns, and the tread of whose hoofs was death, must go the cowboy and his intrepid pony. To drive out the cows and their accompanying calves, so that the brand of the mother might be put on the offspring, was the cow-puncher's duty.

Jerry and John were as usual near together, and Jerry as usual grumbling. He declared that this cow-punching was a dog's life and that he would surely quit it after this round-up. John, as was his custom of late, was discoursing on the merits of "Lite." "I'll show you what a good cutting-out horse he is to-day," the youngster was saying. "You just watch him." Jerry suddenly rode off to head off a steer that had broken out of the bunch and so stopped the boy's talk. When he came back John was about to dismount to aid a weak calf to rise. "Look out!" was all Jerry had time to shout, as an old cow with horns like spears came charging down on the stooping boy. It was not her calf, but she thought it was. John's horse had become startled and ran back so fast that he could not reach the saddle horn to mount. The infuriated cow was within twenty feet of him, the cattle hedged him in on every side so he could not run, and he reached round for his six-shooter as a last resort. He was about to pull the trigger when Jerry's rope came flying through the air, settled round the animal's hind legs, and down she came in a heap just in time.

"You'll take my word next time when I tell you not to dismount in a bunch of cattle." John said nothing, but he realized that it was a pretty close shave.

Soon the cutting-out process began, to accomplish which the rider enters the main bunch, selects a cow with a calf bearing the brand of his outfit, and drives them out to a place apart, where other riders keep them separated from the main bunch and from the similar collections of other brands. To select his own brand from dozens of others requires a quick and sure eye on the part of the rider, and to follow that particular cow through all the turnings and twistings she is sure to take, requires great cleverness and perseverance on the part of the horse.
