The long nodding line of woolly forms, lifting like the crest of a yellow wave, plunged out and down in rounded billow over the canyon rim. With din of hoofs and bleats the sheep spilled themselves over the precipice, and an awful deafening roar boomed up from the river, like the spreading thunderous crash of an avalanche. How endless seemed that fatal plunge! The last line of sheep, pressing close to those gone before, and yet impelled by the strange instinct of life, turned their eyes too late on the brink, carried over by their own momentum. The sliding roar ceased; its echo, muffled and hollow, pealed from the cliffs, then rumbled down the canyon to merge at length in the sullen, dull, continuous sound of the rapids. Hare turned at last from that narrow iron-walled cleft, the depth of which he had not seen, and now had no wish to see; and his eyes fell upon a little Navajo lamb limping in the trail of the flock, headed for the canyon, as sure as its mother in purpose. He dismounted and seized it to find, to his infinite wonder and gladness, that it wore a string and bell round its neck. It was Mescal's pet. X. RIDING THE RANGES THE shepherds were home in the oasis that evening, and next day the tragedy of the sheep was a thing of the past. No other circumstance of Hare's four months with the Naabs had so affected him as this swift inevitable sweeping away of the flock; nothing else had so vividly told him the nature of this country of abrupt heights and depths. He remembered August Naab's magnificent gesture of despair; and now the man was cheerful again; he showed no sign of his great loss. His tasks were many, and when one was done, he went on to the next. If Hare had not had many proofs of this Mormon's feeling he would have thought him callous. August Naab trusted God and men, loved animals, did what he had to do with all his force, and accepted fate. The tragedy of the sheep had been only an incident in a tragical life--that Hare divined with awe. Mescal sorrowed, and Wolf mourned in sympathy with her, for their occupation was gone, but both brightened when August made known his intention to cross the river to the Navajo range, to trade with the Indians for another flock. He began his preparations immediately. The snow-freshets had long run out of the river, the water was low, and he wanted to fetch the sheep down before the summer rains. He also wanted to find out what kept his son Snap so long among the Navajos. “I'll take Billy and go at once. Dave, you join George and Zeke out on the Silver Cup range. Take Jack with you. Brand all the cattle you can before the snow flies. Get out of Dene's way if he rides over, and avoid Holderness's men. I'll have no fights. But keep your eyes sharp for their doings.”
