John Slaughter brought his first herd west of the Pecos with the coming of the grass, and his cow-boys lined them out on this forbidding route. They crossed wide reaches of sand-dunes and alkali flats--ninety miles was the length of one of those dry drives--where they never saw a water-hole for days, until the cattle went blind from thirst and sun-glare and wandered aimlessly over the baked earth lolling their tongues, moaning for drink, ignoring the red-eyed riders who spurred their famished ponies through the stifling dust-cloud and sought by shouts and flaming pistols to hold them to the proper course. The Apaches watched them coming from the heights and crept down to ambush them, but John Slaughter had learned Indian-fighting while he was still in his teens until he knew its tricks as well as the savages themselves; and he led his cow-boys out against them, picking his own ground, swooping down on them from vantage-points, routing them. The herd came on into the long thin valleys which reach like fingers from northern Mexico to the Gila River. On the San Pedro the cow-boys turned them southward and the outfit made its last camp near where the town of Hereford stands to-day. Here the Texan established his home ranch, for he had made up his mind to forsake the valley of the Rio Grande for this new country; and hither now, over the trail which he had broken, his men drove other herds; he sold them to the cow-men of southeastern Arizona as fast as they came in. From now on he devoted himself to stocking the ranges of the Santa Cruz, the San Pedro, the Sulphur Springs, and the San Simon, turning a tawny wilderness into a pastoral commonwealth. For he brought more than Texas cattle into this land which had heretofore been the hunting-ground of Apaches, the wild refuge of white renegades more savage than the Indians. Where he came he took with him the law. It was his way--the way he had taken on the Pecos and he kept it now--to stand for his own rights, to fight for them if need be, until he established them; thus he maintained a rule of action, a rule that accorded with the definition of the old English jurist, "prescribing what is right and prohibiting what is wrong." During those days he rode on far journeys, eastward to the Rio Grande, northward to the country where the land breaks toward the gorges of the Colorado; and because a cattle-buyer was always a marked man, carrying large sums of money with him, there were many who sought his life. But these he slew or drove away. There came a time when the demand for stock was so heavy that he looked about him for a new point of supply and saw Mexico. Troops of bandits rode through the southern republic, gathering tribute where they willed. He loaded down pack-mules with dobie dollars, led his cow-boys down across the boundary, played hide and seek with bands of swarthy murderers in the mountains, and battled with them at the desert water-holes.
