He crossed quickly to the bunk-house door and looked in. The room was empty. The supper-bell pealed out, and he heard the cow-men answer it. Now was the appointed moment; he might have no other. With cat-like tread he slipped into the sleeping-quarters, returning in a moment with a revolver. He stared thankfully at the weapon--better this than dishonor. "Why didn't I think of it before? It's perfectly simple. I'll accidentally shoot myself--in the foot." But even as he gazed at the gun he saw that the muzzle was as large as a gopher-hole. A bullet of that size would sink a ship, he meditated in a panic, and as for his foot--what frightful execution it would work! But--it were better to lose a foot than a foot-race, under present conditions, so he began to unlace his shoe. Then realizing the value of circumstantial evidence, he paused. No! His disability must bear all the earmarks of an accident. He must guess the location of his smallest and least important toe, and trust the rest to his marksmanship. Visions of blood-poisoning beset him, and when he pressed the muzzle against the point of his shoe his hand shook with such a palsy that he feared he might miss. He steeled himself with the thought that other men had snuffed out life itself in this manner, then sat down upon the floor and cocked the weapon a second time. He wondered if the shock might, by any chance, numb him into unconsciousness. If so, he might bleed to death before assistance arrived. But he had nothing to do with that. The only question was, which foot. He regarded them both tenderly. They were nice feet, and had done him many favors. He loved every toe; they were almost like innocent children. It was a dastardly deed to take advantage of them thus, but he advanced the revolver until it pressed firmly against the outside of his left foot, then closed his eyes, and called upon his courage. There came a great roaring in his ears. How long he sat thus waiting for the explosion he did not know, but he opened his eyes at length to find the foot still intact, and the muzzle of the weapon pointing directly at his instep. He altered his aim hurriedly, when, without warning of any sort, a man's figure appeared silhouetted against the window. The figure dropped noiselessly to the floor inside the room, and cried, in a strange voice: "Lock those doors! Quick!" Finding that it was no hallucination, Speed rose, calling out: "Who are you?" "Sh-h-h!" The stranger darted across the room and bolted both doors, while the other felt a chill of apprehension at these sinister precautions. He grasped his revolver firmly while his heart thumped. The fellow's appearance was anything but reassuring: he was swarthy and sun-browned, his clothes were ragged, his overalls were patched; instead of a coat, he wore a loosely flapping vest over a black sateen shirt, long since rusted out to a nondescript brown. "I've been trying to get to you for a week," announced the mysterious visitor hoarsely.
