He was trembling all over with excitement; his blood simply racing in his veins. The night throbbed, his heart swelled as if it would burst. At first he only saw the moonlight, fragile and silvery, over the sleeping sheep. He raised his head. One of the wilderness traits that even the domestic sheep have not altogether lost is the ability to stand absolutely motionless until human eyes get tired of watching. Not a hair twitched on the young ram. It was such a posture as his followers had often seen in him when the flock was menaced by some approaching beast of prey; yet Spot was not thinking of enemies now. And all at once a wild flood of ecstasy passed through his frame. Out of the darkness of the ridge certain living forms came stealing one by one, as silently as stealing shadows. A wonderful and noble monarch—to whom even the wolf made obeisance—was first in the file,—just as Spot had known. Others, even smaller than himself, brought up the rear. And then Spot knew the truth. He knew that his dream was coming true. CHAPTER XXI All the dreams by which Spot knew of his lost heritage were realities to old Argali, leader of a band of wild mountain sheep, or bighorn, that had their craggy home in the high ranges of the Upper Salmon Mountains. The winged danger that fell from the clouds to menace the young lambs was not a memory to him: it was just an unavoidable detail of his life. Perhaps it was more familiar to the ewes, whose lambs were the lights of their souls, but old Argali had become rather indifferent to it years before. For the winged death was simply the great golden eagle who had his eyrie on a high ledge. He had known in his own life the joys that Spot had dreamed about and missed: the wild runs, the leaping from ledge to ledge, the rough games, the glory of the sunset on the high peaks. In his own time he had stood on the high pinnacles and let the last red glow of the sun fall over him. He had known the strife, the danger, the exultation, and his flock would follow him wherever he chose to go. There was no more magnificent creature in the whole mountain world than he. To Hugh, who had never seen a mountain sheep, his coloring would have recalled but one creature on earth,—Spot himself. He had massive horns that could strike with resistless might, sturdy legs and little clinging hoofs that could scale the face of a precipice. A lone wolf wouldn’t have cared to meet old Argali on a narrow trail. Only Broken Fang himself had prowess enough to conquer him in a fair fight,—and Broken Fang usually hunted in the woods far, far below Argali’s range.
