The spot Charley had chosen for the halt was a slight hollow, running east and west; so that, even had the moon been up, they would not have been visible except to any one in the line of the hollow. Here, their carbines cocked and ready for instant use, they remained standing for what appeared to them ages, listening with the most intense earnestness for any sound which might tell of the failure or success of their father's enterprise. Mr. Hardy had ridden on for, as nearly as he could tell, two miles, so that he was now to the southwest of the enemy; then, turning west, he kept along for another mile, when he judged that he was, as nearly as possible, a mile in their direct rear. He now advanced with the greatest caution, every faculty absorbed in the sense of listening. He was soon rewarded by the sound of the baaing of the sheep; and dismounting and leading his horse, he gradually approached the spot. At last, on ascending a slight rise, he fancied that he could make out a black mass, at a distance of a quarter of a mile. Of this, however, he was not certain; but he was sure, from an occasional sound, that the herd was exactly in this direction, and at about that distance. He now left his horse, taking the precaution of tying all four legs, to prevent his starting off at the sound of the rockets. He next set to work to cut some turf, with which he formed a narrow sloping bank, with a hollow for the rocket to rest in--calculating the exact distance, and the angle required. During this operation he stopped every minute or two and listened with his ear on the ground; but except a faint stamping noise from the distant cattle all was quiet. All being prepared, Mr. Hardy took the signal rocket, and placing it at a much higher angle than that intended for the others, struck a match and applied it to the touch-paper. In a moment afterward there was a loud roar, and the rocket soared up, with its train of brilliant sparks behind it, and burst almost over the Indian camp. Five or six balls of an intense white light broke from it, and gradually fell toward the ground, lighting tip the whole surrounding plain. A yell of astonishment and fear broke from the Indians, and in a moment another rocket rushed out. Mr. Hardy watched its fiery way with anxiety, and saw with delight that its direction was true. Describing a slight curve, it rushed full at the black mass, struck something, turned abruptly, and then exploded with a loud report, followed instantly by a cracking noise, like a straggling fusillade of musketry. It had scarcely ceased before the third followed it, greeted, like its predecessors, with a yell from the Indians. Its success was equal to that of its predecessors, and Mr. Hardy was delighted by the sound of a dull, heavy noise, like distant thunder, and knew, that the success was complete, and that he had stampeded the cattle.
