"Does anyone ever go there now?" asked Will.
"Not that I know of," was the reply.
"Then we'll drop down there some time towards morning," Will decided. "And in the meantime," he added, with a wink at his chums, "we'll be looking for a boy tramp out in the railroad yards."
"What do you mean by that"' asked the caretaker.
"Oh, I've just got an idea," replied Will, "that there's a kid hanging around this part of the country whom we ought to interview."
"But I don't understand."
"You wait until we get hold of him, and you'll understand all right!" laughed Will. "We just need that boy!"
"But how do you know there is such a boy?" urged the caretaker.
"He gets it out of a dream book!" Tommy chuckled.
"Do you mean to say that there is some go-between the boys who may or may not be in the mine and some persons outside who are interested in them?" asked the caretaker.
