Arkansas, yet irregular ridges occasionally cut across, adding to the confusion. The entire surrounding landscape presented the same aspect, with no special object upon which the eye could rest for guidance—no tree, no upheaval of rock, no peculiarity of summit, no snake-like trail,—all about extended the same dull, dead monotony of brown, sun-baked hills, with slightly greener depressions lying between, interspersed by patches of sand or the white gleam of alkali. It was a dreary, deserted land, parched under the hot summer sun, brightened by no vegetation, excepting sparse bunches of buffalo grass or an occasional stunted sage bush, and disclosing nowhere slightest sign of human habitation. The rising sun reddened the crest of the hills, and the rider, halting his willing horse, sat motionless, gazing steadily into the southwest. Apparently he perceived nothing there unusual, for he slowly turned his body about in the saddle, sweeping his eyes, inch by inch, along the line of the horizon, until the entire circuit had been completed. Then his compressed lips smiled slightly, his hand unconsciously patting the horse's neck. “I reckon we're still alone, old girl,” he said quietly, a bit of Southern drawl in the voice. “We'll try for the trail, and take it easy.” He swung stiffly out of the saddle, and with reins dangling over his shoulder, began the slower advance on foot, the exhausted horse trailing behind. His was not a situation in which one could feel certain of safety, for any ridge might conceal the wary foemen he sought to avoid, yet he proceeded now with renewed confidence. It was the Summer of 1868, and the place the very heart of the Indian country, with every separate tribe ranging between the Yellowstone and the Brazos, either restless or openly on the war-path.

For once at least the Plains Indians had discovered a common cause, tribal differences had been adjusted in war against the white invader, and Kiowas, Comanches, Arapahoes, Cheyennes, and Sioux, had become welded together in savage brotherhood. To oppose them were the scattered and unorganized settlers lining the more eastern streams, guarded by small detachments of regular troops posted here and there amid that broad wilderness, scarcely within touch of each
