But for several years before the coming of the Pratts certain other ominous events were taking place. Over the mountains from the West, or up the slope from New Mexico, enormous herds of small, greasy sheep began to appear. They were "walking" for better pasture, and where they went they destroyed the grasses and poisoned the ground with foul odors. Cattle and horses would not touch any grass which had been even touched by these ill-smelling woolly creatures. There had been ill-feeling between sheepmen and cattlemen from the first, but as water became scarcer and the range more fully stocked, bitterness developed into hatred and warfare. Sheep herders were considered outcasts, and of no social account. To kill one was by some considered a kindness, for it ended the misery of a man who would go crazy watching the shifting, crawling maggots anyway. It was bad enough to be a cow milker, but to be a sheep herder was living death. These herds thickened from year to year. They followed the feed, were clipped once, sometimes twice, and then were headed back to winter in the south, dying in myriads on the way--only to reappear augmented in numbers the succeeding year. They were worthless as mutton, and at first were never shipped, but as the flocks were graded up, the best were culled and sent to Eastern markets. They menaced the cattlemen in the West and South, while the rancher made slow but inexorable advance on the East. As the cattleman came to understand this his face grew dark and sullen, but thus far no herd had entered the Big Sandy Range, though Williams feared their coming and was ready to do battle. At the precise time that Daniel Pratt was entering Cheyenne County from the East, a Mexican sheepman was moving toward the Cannon Ball from the Southwest, walking behind ten thousand sheep, leaving a dusty, bare and stinking trail behind him. Williams' report drew the attention of the cattlemen, and the Pratts were for the time forgotten. A few days after Daniel's assault on the fences of the big ranch, a conference of cattlemen met and appointed a committee to wait upon the owner of the approaching flock of sheep. The Pratts heard of this, and, for reasons of their own, determined to be present. Mose, eager to see the outcome of these exciting movements, accompanied the Pratts on their ride over the hills. They found the man and his herders encamped on the bank of a little stream in a smooth and beautiful valley. He had a covered wagon and a small tent, and a team of hobbled horses was feeding near. Before the farmers had time to cross the stream the cattlemen came in sight, riding rapidly, and the Pratts waited for them to come up. As they halted on the opposite bank of the stream the sheep owner came out of his tent with a rifle in his arm and advanced calmly to meet them.
