Thus far the Indians had only come at a run over the hill, though some of them had given utterance to a wild yell. The keen eyes of Kit Carey saw that they were in full war-paint, and he felt that to fly was their only safety. Had he been alone he might have been tempted to test their friendship by a parley, but with Emma Foshay along, he dared not. He was not willing to fire the first shot, the Sioux must do that. So away the two horses bounded, side by side, and the act brought forth a series of wild yells that caused the color to leave the face of the young girl, though she remained outwardly calm. "Ride on, Miss Foshay, for I wish to get a better look at them." "And you?" "Will follow close upon the heels of your horse." "No, you see what I do, that the Indians are preparing to fire, and wish to protect me by your own form. We ride side by side, Lieutenant Carey." Kit laughed lightly, at being so understood, and glancing behind him saw the puff of smoke from a dozen rifles, followed by the reports and the whizz of the bullets. "So that is the way a bullet sounds, is it?" coolly said Emma Foshay, as the leaden messengers flew by, evidently fired to frighten and not hit the fugitives. "Yes, they make unpleasant music, Miss Foshay; but once we get over that rise we must try and press on out of range." Soon after the horses dashed over the rise referred to, and were then put to their full speed, and rapidly gained upon the redskins, who, coming again in sight, now fired at their flying foes. "Ha! my horse is hit, but I hope it is nothing serious," said the lieutenant, as he heard the thud of the bullet when it hit his horse, and felt the splendid animal writhe under him. "There is the trail to the agency, Miss Foshay, and we will turn into it soon. The animal you ride knows the way well, should mine fail, and he will carry you there in a few hours, while I am sure no other redskins are between us and the camp. Ah! my poor comrade, you are feeling your wound," and Lieutenant Carey patted the animal affectionately as he felt him failing. "Quick! Lieutenant Carey, mount behind me!" cried Emma, as she saw the wounded horse staggering. "I will try it at least; but if we cannot keep ahead then you must go on alone." He tore off his holsters as he spoke, leaped from his saddle just as his horse stumbled and fell, and with a spring was behind the young girl. The redskins yelled with savage triumph, and pressed their ponies harder. Turning into the broad trail to the agency the horse held his own for a while, though bearing his double weight. At last Kit Carey spoke, and his voice meant all he said: "Miss Foshay, no horse can stand this, and to force him to it will end in untold misery to you, as well as to me. I shall drop off at yonder ridge, and you must go on, not pressing your horse too hard, for I will check the Indians for awhile, at least."
