"I guess we have!" agreed Tommy. "We've let the third boy get away from us! And we couldn't have done a worse thing!" he went on, "because the boys in the mine will know that we are still in this vicinity!"
While the boys stood blaming themselves the sharp call of the Wolf pack came to them.
CHAPTER XI
A KNOCK AT THE DOOR
When Will and George came to the back of the weigh-house they heard some one moving about at the front.
"That's probably the caretaker, taking his last look for the night," suggested Will. "He pokes around all the outbuildings every night before he goes to bed. At least, he is supposed to."
"But this fellow hasn't got any lantern," urged George.
"The plot deepens!" chuckled Will.
"Can you crawl around there and see who it is," asked George, "or shall I go? It may be a thief, or it may be Ventner, or it may be this boy we're looking for. Anyway, we want to know who it is!"
"I'll go!" Will suggested, "and don't you make any racket if you hear something doing there. The one thing to do at this time is to keep our presence here a profound secret."
