How well Bob Buckley had kept his secret, since these men, for two years his side comrades in countless border raids and dangers, thus spake of him, not knowing that he was the most arrant physical coward in all that Rio Bravo country! Neither his friends nor his enemies had suspected him of aught else than the finest courage. It was purely a physical cowardice, and only by an extreme, grim effort of will had he forced his craven body to do the bravest deeds. Scourging himself always, as a monk whips his besetting sin, Buckley threw himself with apparent recklessness into every danger, with the hope of some day ridding himself of the despised affliction. But each successive test brought no relief, and the ranger's face, by nature adapted to cheerfulness and good-humour, became set to the guise of gloomy melancholy. Thus, while the frontier admired his deeds, and his prowess was celebrated in print and by word of mouth in many camp-fires in the valley of the Bravo, his heart was sick within him. Only himself knew of the horrible tightening of the chest, the dry mouth, the weakening of the spine, the agony of the strung nerves--the never-failing symptoms of his shameful malady. One mere boy in his company was wont to enter a fray with a leg perched flippantly about the horn of his saddle, a cigarette hanging from his lips, which emitted smoke and original slogans of clever invention. Buckley would have given a year's pay to attain that devil-may-care method. Once the debonair youth said to him: "Buck, you go into a scrap like it was a funeral. Not," he added, with a complimentary wave of his tin cup, "but what it generally is." Buckley's conscience was of the New England order with Western adjustments, and he continued to get his rebellious body into as many difficulties as possible; wherefore, on that sultry afternoon he chose to drive his own protesting limbs to investigation of that sudden alarm that had startled the peace and dignity of the State. Two squares down the street stood the Top Notch Saloon. Here Buckley came upon signs of recent upheaval. A few curious spectators pressed about its front entrance, grinding beneath their heels the fragments of a plate-glass window. Inside, Buckley found Bud Dawson utterly ignoring a bullet wound in his shoulder, while he feelingly wept at having to explain why he failed to drop the "blamed masquerooter," who shot him. At the entrance of the ranger Bud turned appealingly to him for confirmation of the devastation he might have dealt. "You know, Buck, I'd 'a' plum got him, first rattle, if I'd thought a minute. Come in a-masque-rootin', playin' female till he got the drop, and turned loose. I never reached for a gun, thinkin' it was sure Chihuahua Betty, or Mrs. Atwater, or anyhow one of the Mayfield girls comin' a-gunnin', which they might, liable as not. I never thought of that blamed Garcia until--" "Garcia!" snapped Buckley. "How did he get over here?"
