Roy's first care was to put his lamp behind the rock out of sight, and his second to pull his bicycle case off his shoulder and take out the rifle it contained. He had done considerable shooting with it since he had been on the road, although it had not yet brought him a young squirrel for his dinner. As often as he and his companions halted for a rest their little weapons were brought out, and Roy had learned by actual test that the one he owned could be depended on to shoot "right where it was held."
"Now I am ready for them," said Roy, taking his stand behind the rock outside the circle of light that came from the lamp. "If they advance along the road they had better make sure work of me at the start, for if they don't, some of them will get hurt."
If the train-wreckers were hidden where they could see him (and it was reasonable to suppose they were), they must have taken note of Roy's movements, and perhaps they saw that he had a weapon of some sort in his hands and was ready to defend himself. Be that as it may, they did not molest him, and the boy stuck to his post until the glare of the locomotive headlight fell upon him. The train was moving slowly, and that was proof enough that Joe Wayring had warned it; but to make sure of it, Roy caught up his lamp and "called for brakes the best he knew how." The engineer was the first man to speak to him, and when Roy called his attention to the marks on the rock, the big footprints on the ground and the timbers that were scattered about, the brave fellow turned so white that it showed through the black on his face. He in turn told the conductor, and the latter at once threw the timbers into the ditch, and pitched the pieces of round wood into the gulf.
"Don't lisp a word of it," he said, earnestly. "We've got a heavy, packed train, and the folks would be scared to death. Young fellow," he added, turning to give Joe Wayring a hearty slap on the shoulder, "you have been the means of preventing a slaughter. I'll bet there isn't another wheelman in the State who can ride over that trestle."
"Haw, haw!" laughed Joe. "I guess you haven't seen many wheelmen, have you?"
"Or who would have the courage to attempt it in daylight, let alone a dark night like this," continued the conductor. "Why, man alive, it's a very narrow plank that was put there for the convenience of the track-walker, and the trestle is sixty feet high and half a mile long."
"I am glad I didn't know that when I was going over it," was all Joe had to say in reply.
This is what I meant when I said a while ago that little things often bring about great events. I now know that my master was frightened out of a year's growth when he found himself on that trestle, but he had confidence and nerve enough to go ahead without attempting to dismount. It was that short interview with the strange wheelman that did it, and made Joe Wayring the steady rider he was that night. He knew as well as anybody that he "wobbled too much," but he supposed that was something every novice did, and that the fault would correct itself without any care or trouble on his part. But as soon as his attention was called to it he promptly set about "mending his style," and this was the result. He was glad of it now. It was the only thing that put it in his power to save the train, for on the day he encountered that strange wheelman he could not have ridden fifty feet on an eight-inch plank at full speed without falling off.
By this time all the trainmen had come forward, accompanied by some of the wakeful passengers who wanted to inquire into the cause of this second stoppage, and by their united efforts the rock was tumbled harmlessly over the brink of the gulf and the engineer pulled out for Dorchester, keeping watch along the way for Arthur Hastings. He found him about two miles farther on, but the boy was not signaling, because the appearance of the train was proof enough that Joe had met and warned it. Arthur was surprised to see it come to a stop at the place where he got off the track, and to hear the engineer shout at him to chuck his bike into the baggage car and get aboard, for he was half an hour behind already. But he lost not a moment in thinking about it after he saw Joe and Roy beckoning to him from the platform of one of the passenger cars, and the train once more started on its way, this time moving at a rate of speed that gave me a faint idea of the crash that would have followed and the fearful loss of life that would have taken place if it had come in contact with that bowlder.
This is the substance of the story Roy's wheel told me during the run to Dorchester, and the one to which Joe and Arthur listened while perched upon the wood-box in one of the crowded cars. The conductor could not give them a seat, for every one was filled with weary travelers who had slumbered serenely through it all, and who when they awoke at intervals, and looked with sleepy eyes toward the three dusty, white-faced boys behind the stove-pipe, never dreamed that one of them, a short half-hour before, held all their lives in his hand. The conductor knew it and could hardly find words with which to express his gratitude, although he tried hard enough. The young wheelmen conversed in whispers and looked frightened, as indeed they were; and Joe Wayring hoped from the bottom of his heart that no such responsibility would ever devolve upon him again.
