"Oh!" he said, wringing his hands, "I dare not do it! I dare not do it!"

He rushed past the blazing heap, paused. "Fool!" he said, "what is there to fear?"

He crept back to the pile of burning brush, seized a blazing ember, ran with it to the train he had prepared of rags soaked in kerosene, leading toward the mouth of the cross tunnel, dropped the blazing stick upon it, and fled. Looking back, he saw that in his haste he had dashed out the flame and that besides the saturated rags the stick lay smoking. With a curse he ran once more to the blazing brush heap, selected a blazing ember, carried it carefully to the train, and set the saturated rags on fire, waiting until they were fully alight. Then like a man pursued by demons, he fled down the ravine, splashed through the Creek and up the other side, not pausing to look behind until he had shut the door of his cabin.

As he closed the door, a dark figure appeared, slipped up to the door, there was a click, a second, and a third, and the door stood securely fastened with three stout padlocks. In another moment Rosenblatt's livid face appeared at the little square window which overlooked the ravine.

At the same instant, upon the opposite side of the ravine, appeared Brown, riding down the slope like a madman, and shouting at the top of his voice, "French! French! Kalman! For God's sake, come here!"

Out of the cave rushed the two men. As they appeared Brown stood waving his hands wildly. "Come here! Come, for God's sake! Come!" His eyes fell upon the blazing train. "Run! run!" he shouted, "for your lives! Run!"

He dashed toward the blazing rags and trampled them under his feet. But the fire had reached the powder. There was a quick hissing sound of a burning fuse, and then a great puff. Brown threw himself on his face and waited, but there was nothing more. His two friends rushed to him and lifted him up.

"What, in Heaven's name, is it, Brown?" cried French.

"Come away!" gasped Brown, stumbling down the ravine and dragging them with him.

Meantime, the whole hillside was in flames. In the clear light of the blazing trees the Sergeant was seen riding his splendid horse at a hard gallop. Soon after his appearing came Portnoff.
