"I'm not only goin' to prove what I've said so far, but I'm goin' to prove that these robberies were a put-up job between you an' Carlisle, with somebody helping you," said Rathburn. "I've been in the mining game myself, Sautee, but in our country men spend their lives hunting metal to make some bunch of stockholders rich. Maybe they get something out of it themselves, an' maybe they don't; but they're square, an' the men that run the mines are square 'most always. Anyway they develop properties, an' that's more'n you're doing. You're not doing this camp any good. You're bleeding the mine an' the company, too." "And I suppose you--The Coyote--are taking a hand in this business as a matter of principle," sneeringly replied Sautee. "I didn't take a hand," Rathburn pointed out sternly. "You an' Carlisle forced a hand on me, an' I'm goin' to play it out. I've another reason, too," he added mysteriously. "Did you say you had Carlisle?" Sautee asked in feigned anxiety. "I've got him dead to rights," replied Rathburn shortly, taking some paper and a pencil from a pocket. Sautee looked at him curiously as he started to write on the paper. "Going to write it all out and leave it?" he asked sneeringly. "I'm going to put it outside the powder house in a place where Mannix or some of the others will be sure to find it," was the puzzling answer. "I suppose they'll believe it quicker if it's in writing," said Sautee bravely. Rathburn finished writing, folded the paper, and placed it in the left-hand pocket of his coat. He carefully put away the pencil. His next act caused Sautee real concern. Using a drill which was there for the purpose, evidently, Rathburn broke open a box of dynamite caps and a box of dynamite. A single coil of fuse was lying on a box. He quickly affixed the cap to a stick of the dynamite and crimped on a two-foot length of fuse. Then he moved the opened box of dynamite to the doorway and struck the stick with cap and fuse attached into it. "There," he said, evidently greatly satisfied with his work. "That fuse will burn about two minutes----" He paused. "That's too long," he concluded. Perspiration again stood out on Sautee's forehead as he watched Rathburn cut off a foot of the fuse. "That's better," said Rathburn with a queer smile. "That'll burn about a minute. Time enough." Sautee stared in horrified fascination at the foot of fuse which stuck straight out from the box of dynamite in the doorway. "What--what are you going to do?" he gasped out. "Listen, Sautee," said Rathburn coolly. "When that stick of powder explodes it'll set off the box an' the other boxes, an' instead of a powder house here there'll be a big hole in the side of the mountain." "Man--man--you're not going to do--_that_!" Sautee's words came in a hoarse whisper. "I reckon that's what I'm goin' to have to do," said Rathburn as he bent over the form on the floor of the powder house. The boy's eyes were open and were staring into Rathburn's.
