What Ralph saw, all hands in the cab soon realized within the ensuing ten minutes. When they had aroused Fogg, there followed animated theory, discovery and conviction. Not one of them doubted but that some enemy had sneaked aboard of the locomotive while it was sidetracked at noon at Riverton and had put some drug in the jar of coffee. They found a suspicious dark sediment at the bottom of the jar. "Black Hands--mark it down," observed Fogg. "Whoever did it, also placed those flasks of liquor in my bunker. See the label on them? They come from a place in Riverton I never was in. The scoundrels aimed to have us found in the cab, just as we have been, and a report go in that the heat and too much liquor had crippled us from making the run." "You've struck it, Fogg," assented the conductor. "Just stow that jar and those two flasks in a safe place. I'll have our special agent Adair, the road detective, find out who bought that liquor. No need of any blabbing to the general public. Are you able to complete the run, Fairbanks?" "Certainly," reported Ralph, exercising arms and feet vigorously to restore their circulation. Fogg was still dazed and weak. He had drunk more of the coffee than Ralph. Besides, being the older of the two, he did not shake off the effects of the narcotic so readily as the young engineer. "I'll help fire--I know how to," declared Clark. "You know how to stop an engine, too!" commented the conductor. "All right, Fairbanks, when you're ready," and he returned to the coaches. Ralph extended his hand to Clark. The latter met his glance frankly. "I've been trying to get track of your movements by telegraph," said Clark. "Located your run, and was waiting at Riverton for your train. Got there ahead of time, and came back to the depot just as 999 was pulling out, and caught the last car. First, I thought I'd not show myself until you got through with your trip. Things got dull in those humdrum coaches, though, and I sailed ahead to the tender, saw what was wrong, and checked up the locomotive just beyond the bridge. Say, if the draw had been open, we'd all have had a bath, eh?" "The miscreants who played this diabolical trick ought to be severely punished," said Ralph. There was no evidence of strained relations between the two boys. Ralph recognized that Clark had sought him out to make an explanation. He wondered what it would be. The present was not, however, the time to broach the subject. There was something very manly and reassuring in Clark's manner, and the young railroader believed that when he got ready to disclose his secret, the revelation would be an unusual and interesting one. The train was started up, soon made up the lost time, and at 5:15 rolled into the depot at Stanley Junction. Ralph did not feel quite as well as usual and his fireman was pale and loggy, but the main effects of the drug had passed off. "You go straight home, Mr. Fogg," directed Ralph. "I will see that 999 is put to bed all right."
