So the eyes of the six men turned to the indicated authority, an Apache of uncertain age. He looked to be forty and might be nearer sixty. He stood five feet ten in his tiptoed moccasins, and weighed less than little Harris, who could not touch the beam at five feet five. Harris was the light weight of the --th Cavalry, in physique, at least, and by no means proud of the distinction. To offset the handicap of lack of stature and weight, and of almost cat-like elasticity of frame and movement, he saw fit to cultivate a deliberation and dignity of manner that in his cadet days had started the sobriquet of "Heavy," later altered to "Hefty"; and Hefty Harris he was to the very hour this story opens--a junior first lieutenant with four years' record of stirring service in the far West, in days when the telegraph had not yet strung the Arizona deserts, and the railway was undreamed of. He had only just returned to the post from a ten days' scout, 'Tonio, the Apache, being his chief trailer and chosen companion on this as on many a previous trip. The two made an odd combination, having little in common beyond that imperturbable self-poise and dignity. The two elsewhere had met with marked success in "locating" _rancherias_ of the hostile bands, and in following and finding marauding parties. The two were looked upon in southern Arizona as "the best in the business," and now, because other leaders had tried much and accomplished little, it had pleased the general commanding the Division of the Pacific to say to his subordinate, the general commanding the Department of Arizona, that as the "Tonto" Apaches and their fellows of the Sierra Blanca seemed too wily for his scouting parties sent out from Whipple Barracks, and the valley garrisons of McDowell and Verde, it might be well to detach Lieutenant Harris from his troop at old Camp Bowie and send him, with 'Tonio, to report to the commanding officer at Camp Almy.
