"You've got to explain to me," George laughed, as the caretaker left the room, and the boys began picking up their clothing, preparatory to the alleged journey. "I can't understand what you mean by saying that you'll watch out for a boy tramp in the railroad yards."
"It's a sure thing, isn't it?" Will asked, "that the boys we are in search of are in the mine? We don't know what they're in there for. They may be hiding there because of some fool notion they have in their heads, or they may have been sent here for some definite purpose."
"You bet they've been sent here for some definite purpose," George replied. "They never came here to work on the breaker without having some well-defined motive. Boys answering to their description don't accept such jobs as they accepted here!"
"Well, the boys are in the mine," Will continued. "As stated, we don't know what they're there for, but we know they're there. Now, this third boy comes to the mine and works just long enough to get in touch with the other two. Then he disappears."
"Buys a lot of provisions and goes down the river to leave his hat on the bank!" laughed Tommy. "I guess that was a pretty poor imitation of a suicide or a drowning accident, either!"
"But this boy didn't get to be intimate with the two breaker boys," contended George. "He talked with them about two minutes after the fight, according to Canfield, but paid no further attention to them after that. If he had any secret understanding with them, he must have done a whole lot of talking in a mighty short space of time."
"The right kind of a boy can say a good deal in a minute and half!" laughed Tommy. "But suppose we let Will go on and explanation us about that boy tramp in the railroad yards. I think I know what he's getting at, but I'm not quite certain. Go on, Will, it's up to you."
"In order to make the connection," laughed Will. "I'll state for the third time that we know that the boys are in the mine. It may also be well to state, once more, that we are reasonably certain that this third boy came to the mine for the specific purpose of communicating with the other two. Now, this boy didn't drop into the river. He dropped the provisions he bought for the boat into the coal mine, and left them there for the consumption of the two boys inside. That's reasonable, isn' it?"
"Fine deduction, as Sherlock Holmes would say to Watson!" laughed George.
"But this third boy," Will went on, "doesn't go into the mine. He stays outside to serve as a means of communication between the boys who are hiding in the mine and some interested person or persons on the outside. That's perfectly clear, isn't it?"
