The Shawanoe had halted on the edge of the pasturage ground, glanced quickly over his field of vision, and then, placing a thumb and forefinger between his teeth, he emitted a blast like that of a steam whistle. It was a signal he had taught the stallion, and he knew that if the horse was within a mile he would come toward him on a full gallop. Deerfoot repeated the call twice and then waited and looked and listened. None of the horses so much as raised his head, and the heart of the youth became like lead. "Whirlwind is not here," he said sadly to the Blackfoot. George and Victor hurried back, drawn by the signal whose meaning they understood. In truth, when they left his side it had been more for the purpose of hunting for the stallion than for their own animals. Their hearts ached for Deerfoot, whose face was the picture of disappointment and grief. "Call to him again," suggested George. "It can do no good. If he is near he would have heard Deerfoot; he is gone." "He may have wandered beyond reach of your signal," said Victor. "You know he never felt friendly toward other horses and always kept by himself." With a weak hope that his friend was right, Deerfoot walked a hundred yards to where an uprooted tree lay on its side, climbed upon the trunk, and, facing the different points of the compass in turn, whistled so shrilly that in the afternoon stillness the sound awoke the echoes for miles in every direction. Then he stood in the attitude of intense attention. Certain that the stallion had not gone far of his own accord, he knew these calls would bring him dashing to the spot, provided no person had had a hand in his disappearance. But the minutes passed without anything of this nature occurring, and the Shawanoe sprang down from the slight elevation and came back to where his sympathizing friends awaited him. They were silent, for none could say aught to comfort him. "We will look for Amokeat," he quietly remarked, leading the way to the village. There the inquiries of Mul-tal-la brought the first definite information of the missing horse. It was of anything but a pleasant nature. It has been said that about a score of Nez Perce warriors were absent on a scouting or hunting expedition. They were under the lead of Amokeat, who rode away on the back of Whirlwind. They had been gone several days and were liable to return at any hour, or they might be absent for a week or more longer. When Deerfoot gained this information he was filled with indignation. Without speaking, he turned his back upon his friends and walked to and fro for several minutes. He was striving to gain control of his emotions, and some time passed before he could do so. When he succeeded he rejoined his comrades, several of the Nez Perces gathering round and watching the four with no little curiosity.
