miles of one another claim precedence--and Indian and Horsehead creeks are placidly willing to share it with them. The sun rises over the broad lands of the Sioux to the eastward as we leave the shadowy Niobrara behind. Merritt's swift-stepping gray at the head of the column keeps us on our mettle to save our distance, and the horses answer gamely to the pressing knees of their riders. At 10.15 we sight the palisade fortifications of the infantry company which guards the spring at the head of old Sage Creek, and Lieutenant Taylor eagerly welcomes us. Here, officers, men, and horses take a hurried but substantial lunch. We open fresh boxes of ammunition, and cram belts and pockets until every man is loaded like a deep-sea diver, and fairly bristles with deadly missiles. Then on we go. East-northeast over the rolling, treeless prairie, and far to our right and rear runs the high, rock-faced ridge that shuts out the cold north winds from the reservation. The day is hot; we are following the Black Hills road, and the dust rises in heavy clouds above us. But 'tis a long, long way to the Indian crossing, and we _must_ be the first to reach it. At sunset a winding belt of green in a distant depression marks the presence of a stream. At eight p.m., silently under the stars, we glide in among the timbers. At nine the seven companies are unsaddled and in bivouac close under the bluffs, where a little plateau, around which the creek sweeps in almost complete circle, forms excellent defensive lair, secure against surprise. We have marched eighty-five miles in thirty-one hours, and here we are, square in their front, ready and eager to dispute with the Cheyennes their crossing on the morrow. No fires are lighted, except a few tiny blazes in deep-dug holes, whence no betraying flame may escape. Horses and men, we bivouac in a great circle along the steep banks of a sluggish stream. The stars shine brightly overhead, but in the timber the darkness is intense. Mason, my captain, and I are just unstrapping our blankets and preparing for a nap, when Lieutenant Forbush, then adjutant of the regiment, stumbles over a fallen tree, and announces that Company "K" is detailed for guard and picket. I had "been on" all the night before with Captain Hayes, and would gladly have had a sound sleep before the morrow's work; but when Mason, after reporting for orders to General Merritt, comes back and tells me that I am to have command of the outposts to the southeast, the direction from which the foe must come, there is compensation in the supposed mistake in the roster.
