"Let us out of here!" bellowed Sercomb, as frantic fists pounded on the door. "We want to go East on that train."

"So do we," answered Matt, "and you'd have kept us from it if you could. Turn about is fair play, Sercomb. I'll reach Ottawa in time to see this man Trueman, whom you were talking about. Much obliged for the tip. You fellows can follow on the train Carl and I would have had to take in case you had been successful and locked us in there."

"Let us out, King," bawled Mings, "or you'll be sorry you didn't! Take that from me!"

"I've taken a whole lot from you fellows already, Mings," answered Matt, "and I'm getting tired of it. If I can ever catch Slocum he'll tell all about that trickery of his in the Clifton Hotel, or he'll wish he had."

"Dot's righdt!" put in Carl. "You vas a lot oof schmard Alecs, und pooty kevick you vas going to findt oudt dot it don'd pay to act like vot you dit. Dere iss so many oof you dot you von't be lonesome in dere, und ven you come py Oddawa, Modor Matt und I vill meed you mit der pand. Ach, you vas a fine punch oof grafders!"

The door shook and shivered as those inside the shed hurled themselves against it; but it was strongly put together and the baffled drivers could not break it down or force it open.

Carl, shaking with enjoyment, stood off and watched the door bulge outward and rattle back into place.

Presently the attack ceased.

"Look here, King," called the breathless voice of Sercomb, "if you'll let us out of here we'll agree to quit bothering you. Ain't that fair enough?"

"I'm not making any terms with you, Sercomb," replied Matt. "You're too tricky to be trusted."
