"I didn't say anything of the kind!" replied Will.

"There are times," Tommy explained to Canfield, "when the gift of frank speech is taken away from Will, so you mustn't blame him for not answering. He'll tell you all about it when the time comes."

The caretaker went away with a puzzled look on his honest face.

CHAPTER IX

WHO DISCOVERED THE LEAK?

"You've got to explanation 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!"
