"No, we didn't find any loose rock to lift."

"That rock was loose. I remember how it seemed to tip when we moved. In all I've read about treasure there never was any left just on top of the ground, except in Treasure Island, and even that was buried until Ben Gunn carried it to the cave. I'd like to look under that rock."

"We'll go back with you, Matty," chorused a dozen scouts, only too glad of further exploration.

"Mr. Newton, the water's gone down so much I'm sure I can get through without wetting my head. Please let me try it," begged Matt.

"If ye don't he'll be so excited his brains'll spill out o' that gash, they will," urged Chick-chick.

"I'll give him all the help he needs," offered Glen.

"I'll go along myself," said Mr. Newton. "I guess we can manage him between us."

So back the whole expedition went convoying Matty to the cave. He led them straight to the ledge of rock and the stamp of a foot was enough to show its lack of balance.

The boys were greatly excited—even Mr. Newton showed immense interest.

"Use the pickaxes to pry, boys. Get under these loose corners," directed the scoutmaster. "Tom and Glen, you two are the strongest—one at each corner now."
