"Get in your herd, sergeant!" he shouted at the top of his voice; and over the rushing of the Laramie his words reached the rousing bivouac, and saddle blankets were sent swinging in air in signal to the distant guards, and within a few seconds every horse was headed for home; and then, to the sound of excited voices was added the rising thunder of scores of bounding hoofs, as, all in a dust-cloud of their own, the sixty chargers came galloping in, ears erect, eyes ablaze, nostrils wide, manes and tails streaming in the breeze, guided by their eager guards full tilt for camp. Out ran their riders, bridles in hand, to meet and check them, every horse when within a few yards of his master seeming to settle on his haunches and plow up the turf in the sudden effort to check his speed, long months of service on the plains and in the heart of Indian land having taught them in times of alarm or peril that the quicker they reached the guiding hand and bore, each, his soldier on his back, the quicker would vanish the common foe. Even before the panting steed of the headlong courier came within hailing distance of the ranch, half the horses in the troop were caught and the bits were rattling between their teeth; then, as the messenger tore along the gentle slope that led to the gateway, his wearied horse laboring painfully at the rise, Mrs. Folsom recognized one of her husband's herdsmen, a man who had lived long years in Wyoming and could be unnerved by no false alarm, and her voice went up in a shriek of fear as she read the tidings in his almost ghastly face. "Where is Hal?" she screamed. "Oh, what has happened?" "He's safe," was the answering call, as the rider waved a reassuring hand, but at the instant he bent low. "Thank God, you're here, lieutenant," he gasped. "Mount quick. Hal's corralled two miles out there under the butte--Sioux!" And then they saw that he was swooning, that the blood was streaming down the left thigh and leg, and before hand could help him, he rolled senseless, doubled up in the dust at his horse's feet, and the weary creature never even started.
