They started away immediately, Ben promising to be back before daylight. When he returned just before sunrise DuBois was with him and he bore an astonishing piece of information.

THE BOY AND THE BEAR.

Carl slept little that night. The man who had given his name as Frank Harris occupied the tent with him and the two talked until a very late hour. The boy saw from the first that his inquisitor was trying to obtain all the information in his possession regarding the purpose of the Flying Machine Boys in visiting British Columbia.

It is needless to say that no mention was made of the Colleton case. Carl knew that the fellow was talking round and round the subject, but he did not see fit to swallow the bait and mention the name of the abducted post-office inspector.

Harris talked a great deal about Wall street and the chances for young boys there, and repeatedly suggested that Carl and Jimmie join his office force. The boy understood what this all meant, and did not “fall for the fly,” as Jimmie might have expressed it.

“I’d like to know how I’m ever going to get back to our camp,” Carl said, as Harris mentioned the possibility of his return the next day.

“I don’t know whether they will or not!” answered Carl. “You fellows scared Jimmie away so he won’t be likely to return right off.”

“He needn’t have been afraid,” Harris laughed. “We wanted to entertain the two of you, and, besides, some of the fellows wanted to take a look at the machine!”
