"I grappled with Gerardo, just as he was boarding the cab and before he could establish his position, I hurled him, heels over head, down the side of the track. At the same moment, however, I heard a sharp report and felt a stinging sensation in my right arm, where the outlaw's bullet had struck me. "The firing had nearly ceased at the rear of the train, and feeling that in another minute we should be safe, I sprang to the lever and threw the valve wide open. With snorts and shrieks of defiance to our enemies, the old engine obeyed me, soon gaining a rate of speed which I knew would out-distance the baffled outlaws, whose yells I could still hear above the thunder of the train. "As my excitement abated my arm began to pain me fearfully, and I found the member disabled for further use. My fireman gone, my situation was critical, and I was wondering how the rest of the boys had fared when I heard some one behind me. "Half expecting to meet one of the outlaws, I turned, and was glad to see one of the brakemen, who had come to my assistance. "'We have repulsed them, but they are following us,' he said, in reply to my anxious questions. "'Well, let them follow,' I answered, 'if they think they can overtake my Bonny Bess. Give her more fuel, Ned. You will have to be my--' "I did not finish my sentence, for at that moment, as we shot around a curve, great tongues of fire leaped from the track ahead of us. It was a bridge in a blaze of flame, and in the light of the burning structure I saw a dozen of Gerardo's band waiting our coming. "We were going at lightning-like speed, and we were within twenty rods of the fire when I discovered it, so I had no time to hesitate upon my course of action. Quick as a flash I realized the trap Gerardo had laid--our situation. To stop was to throw ourselves into the hands of his followers, which meant death. The bridge was still standing. It might hold us to cross over. There was at least a chance. To stop was hopeless. "All this seemed to come to me at one thought. I would keep on. Bonny Bess was doing her prettiest and I gave her a free bit; that is, in our parlance, 'linked her up.' My left hand was on the lever and my gaze was fixed on the burning bridge, which hung, a network of fire, over the glowing river, thirty feet below. "I heard the shouts of the amazed outlaws above the roar of the train, and then I felt the bridge quiver and tremble beneath me, as we were borne over its swaying spans, amid a cloud of ashes, smoke and cinders, which fairly blinded me. "The blazing girders overhead sent out their forked tongues of fire, and from the timbers below leaped up the sheets of flame until we were enveloped in the fiery shroud. Blinded, stifled for a moment, I then felt the cool night air fan my face, and the engine no longer shook as if upon uncertain footing.
