All remonstrances with the brave girl proving useless, the two scouts prepared for a vigorous defense. The attack by the Indians commenced in front, where from the nature of the ground they were obliged to advance in single file, sheltering themselves as they best could, behind rocks and trees. Availing themselves of the slightest exposure of the warriors bodies, the scouts made every shot tell upon them, and succeeded for a time in keeping them in check. The Indians meanwhile made for an isolated rock on the southern hillside, and having reached it, opened fire upon the scouts at point blank range. The situation of the defenders was now almost hopeless; but the brave never despair. They, calmly watched the movements of the warriors and calculated the few chances of escape which remained. McClelland saw a tall, swarthy figure preparing to spring from cover to a point from which their position would be completely commanded. He felt that much depended upon one lucky shot, and although but a single inch of the warrior's body was exposed, and at a distance of one hundred yards, yet he resolved to take the risk of a shot at this diminutive target. Coolly raising the rifle to his eye, and shading the sight with his hand, he threw a bead so accurately that he felt perfectly confident that his bullet would pierce the mark; but when the hammer fell, instead of striking fire, it crushed his flint into a hundred fragments. Rapidly, but with the utmost composure, he proceeded to adjust a new flint, casting meantime many a furtive glance towards the critical point. Before his task was completed he saw the warrior strain every muscle for the leap, and, with the agility of a deer, bound towards the rock; but instead of reaching it, he fell between and rolled fifty feet down hill. He had received a death-shot from some unseen hand, and the mournful whoops of the savages gave token that they had lost a favorite warrior. The advantage thus gained was only momentary. The Indians slowly advanced in front and on the flank, and only the incessant fire of the scouts sufficed to keep them in check. A second savage attempted to gain the eminence which commanded the position where the scouts were posted, but just as he was about to attain his object, McClelland saw him turn a summerset, and, with a frightful yell, fall down the hill, a corpse. The mysterious agent had again interposed in their behalf. The sun was now disappearing behind the western hills, and the savages, dismayed by their losses, retired a short distance for the purpose of devising some new mode of attack. This respite was most welcome to the scouts, whose nerves had been kept in a state of severe tension for several hours. Now for the first time they missed the girl and supposed that she had either fled to her old captors or had been killed in the fight. Their doubts were soon dispelled by the appearance of the girl herself, advancing toward them from among the rocks, with a rifle in her hand.
