A moment later Fred emerged, his face covered with dirt.

“What are you two doing?” demanded Grant, who now approached the two conspirators. “You look as though you were training to be a mole, Fred.”

“There’s a box down in there,” said Fred. “We want to get it out.”

“A box!” exclaimed Grant. “How big is it?”

“I could only feel one end of it. It’s about a foot wide I should say. I don’t know how long it is for all the rest of it is buried in there.”

“Couldn’t you budge it?”

“Not an inch. We’ll have to dig it out.”

“I’ll get that knife Sam made,” exclaimed John. “That’ll be just the thing.”

“Sam’s up by the flag on watch,” Grant called as John started off. “I think he has the knife with him. Who discovered the box?” he inquired, turning to Fred. Grant was now as excited as the other two boys had been.

“John did,” said Fred.
