It wasn't quite as large as that, nor do I suppose it was even half as large as Rube Royall's cabin; but it was big and heavy enough to tax the strength of all the men who could get around it, including the engineer, fireman, conductor, all the brakemen, some of the passengers and two wheelmen. With the aid of levers and much lifting and pushing they got it started at last, and it went down into the gulf with a terrific crash. I heard the engineer say, as he climbed back into his cab, that if he had struck that rock going as fast as he usually did at that place, he would have demolished his train so completely that it would have taken a microscope to find the wreck.

"All clear," shouted the conductor. "All aboard. Pass along that other wheel."

"One moment, please. There's another man in our party who went down that way because we didn't know where to look for the first train," said Joe, waving his hand in the direction in which Arthur Hastings had disappeared. "He'll be back directly, and as we don't care to be separated, perhaps you had better leave us here. We're just as much obliged to you, however."

"Has the other man got a lamp? All right, Jake," said the conductor, addressing the engineer, "keep a lookout for another wheelman a mile or so down the road. That'll be all right. Pile in."

Joe and Roy went into one of the passenger cars, while the latter's wheel was placed at my side against the trunks. The first words he uttered were:

"It's just dreadful to think of, isn't it?"

"Not so much so as it might be," said I. "If I had broken Joe Wayring's head for him while he was driving me at top speed across that trestle, then you might have had something to talk about."

"We've enough as it is. I know it might have been worse, and some unknown villains meant it should be. Roy Sheldon showed the marks to the engineer as soon as he got out of his cab."

"What marks?"

"Why, the marks on the rock. The engineer called the conductor's attention to them, and together they made it up not to say a word about it in the hearing of the passengers for fear of frightening them."
