"What shall we do?" cried Bob, acting as if he was ready to turn and run. "Go and get it," said Hugh instantly. "Come along," and he started towards the spot of danger. Spurred on by his comrade's show of courage, Bob followed. Their hearts were in their throats and terror held them in its grasp as they hurried along. The little sparks still appeared, and the sputtering of the fuse could be heard distinctly as they ran forward. The footing was dangerous and who could tell but that at any moment the bomb might explode and blow them into eternity. Hugh reached the spot first. He was outwardly calm, but had the sun been shining his face would have shown white and frightened. A second later Bob arrived and stood beside him. "There it is," he gasped. "It's a bomb all right." "Pinch the fuse," cried Hugh excitedly. "Put it out." Both boys reached for it, but Bob was first. He had completely recovered his nerve now and was perhaps even more self-possessed than Hugh. Bob grasped the lighted part of the fuse between the thumb and forefinger of his right hand. He squeezed it tightly, but quickly withdrew his hand with a cry of pain. The fuse still sputtered. "Let me!" almost sobbed Hugh. "Let me try." He repeated Bob's performance, except that he held on in spite if the pain he suffered. With tight-shut lips and set jaw he pinched the fuse with all his strength. Finally he could stand it no longer and let go. "It's out," cried Bob. "No, it isn't either," he exclaimed a second later as the fuse once more showed red and the tiny sparks again made their appearance. "We'd better run for it, Hugh. What's the use in our being blown up along with the bridge?" "Get out of the way!" ordered Hugh, and Bob obeyed at once. There was something in the tone of his friend's voice that made him hasten to do as he said. Hugh knelt on the ties and leaned down over the bomb. "Here comes a train," cried Bob suddenly. "On this track too." Hugh paid no attention to this warning. He picked the bomb up in his two hands and staggering under its weight, carried the spitting and sputtering engine of death to the edge of the bridge. With a supreme effort he hurled it from him. A moment later a splash told that it had landed in the river below. "That'll never do any more harm," he gasped faintly. "Stay there, Hugh!" shouted Bob. "Look out for the train!" The two boys crowded close against the side of the bridge and a moment later a heavy train thundered past them. Through the lighted windows could be seen crowds of passengers, and Hugh and Bob shuddered as they thought what might have happened to the train with its load of precious human freight had the bomb exploded. They felt faint and weak after their experience and presently sat down until their shattered nerves should have recovered somewhat from the shock. The night was cool, but Bob mopped his perspiring brow. "Whew," he gasped. "That was a close call."
