The march down Amphibious Creek was grandly beautiful as to scenery. We wound, snake-like, along the stream, gliding under towering, pine-covered heights, or bold, rocky precipices. The valley opened out wider as we neared the "sinks," and, finally, turning abruptly to the right, we dismounted and led our horses over a lofty ridge, bare of trees, and commanding a broad valley to the south, over which the road stretched in long perspective till lost in dark Buffalo Gap, the only exit through the precipitous and lofty range that hemmed in the plain between us and the Cheyenne valley beyond. Here we encountered an emigrant train slowly toiling up the southern slope and staring at us in undisguised wonderment. Ten miles away we came once again "plump" upon the boiling waters of the creek, where it reappeared after a twelve-mile digression in the bowels of the earth. It was clear and fair when it left us in the valley behind to take its plunge, and it met us again with a more than troubled appearance and the worst kind of an odor. Square in between the massive portals of the great gap we unsaddled at sunset and encamped for the night. In the scout which ensued down the valley of the South Cheyenne there was absolutely nothing of sufficient interest to record in these pages.

Such warriors as had remained near Camp Robinson meekly surrendered to General MacKenzie, and we had nothing to do but pitch our tents side by side with the new-comers of the Fourth Cavalry and wonder what was to come next. General Crook was known to be in the garrison with his aides-de-camp, and we had not long to wait. On the 24th of October our motley array received the welcome order to go into winter-quarters, the Fifth Cavalry on the line of the Union Pacific Railroad, and within another twenty-four hours we were _en route_ for the comforts of civilization. But, before we separated from the comrades with whom we had marched and growled these many weary miles, our chief gave us his parting benediction in the following words: "Headquarters Big Horn and Yellowstone Expedition, Camp Robinson, Neb., _October 24, 1876_. "_General Orders No. 8._ "The time having arrived when the troops composing the Big Horn and Yellowstone Expedition are about to separate, the brigadier-general commanding addresses himself to the officers and men of the command to say:
