How could the "boys" from far Nebraska be supposed to know that the little chap had spent his whole life in the shadow of the flag, and had many a time in baby days been dandled on the very arm that was now so deferentially bent and uplifted in soldier homage? What was there in the manner of the youngster to betray the fact that he dreaded old Sergeant Rigney's criticism even more than that of his commanding officer? Then came another phenomenon. At a brief, curt "Sergeant, get out your prisoners," from the beardless lips, there was instant fumbling of big keys and clanking of iron from the hidden recesses of the guard-house. The dismounted troopers sprang suddenly to attention. The guard split in two at its middle, each half facing outward, marched half a dozen paces away like the duellists of old days from the back to back position, halted, faced front once more, and stood again at ease, with a broad gap of a dozen paces between their inner flanks. Into this space, shuffling dejectedly in some cases, stalking defiantly in others, slinking, shivering, and decrepit in the case of two or three poor wrecks of the rum fiend, a stream of humanity in soiled soldier garb came pouring from the prison door and lined up under the eyes of vigilant non-commissioned officers in front of the young lieutenant in command. There they stood, their eyes shifting nervously from group to group of huddling spectators, their shoulders hunched up to their ears--the riff-raff of the garrison--the few desperate, dangerous characters from the surrounding camps, an uncouth, uncanny lot at any time, but looking its worst in the drip of the floating fog-wreaths and the gloom and despond of the dying day. The boom of the sunset gun from Alcatraz fell sullenly on the ear even as the soft trumpets of the cavalry, close at hand, began sounding the "Retreat." At its last prolonged note the sharp crack of an old three-inch rifle echoed the report from Alcatraz, and from the invisible, mist-shrouded top of the staff the dripping folds of the storm-flag came flapping down in view, limp and bedraggled, and the guard sprang again to attention as a burly, red-faced, hearty-looking soldier, with a captain's insignia in loop and braid on the sleeves of his overcoat, broke a way through the group of lookers-on and, barely waiting for the salute and report of the young lieutenant commanding, began a sharp scrutiny of the prisoners before him. Down along the line he went, until at the fourth man from the left in the front rank he stopped short. A bulky, thick-set soldier stood there, a sullen, semi-defiant look about his eyes, a grim set to the jaws bristling with a week-old beard of dirty black. Then came the snapping colloquy. "Your name Murray?" "That's what they call me." "What was your name before that?" "Jim."
