"Polly! If it's copper, then we're rich!"

Both girls rushed over to examine the metallic gleams at close range, and Polly frowned as a thought entered her mind. Eleanor turned and looked about to be sure no one could hear, and then whispered:

"Polly, it looks like gold! Can it be real GOLD!"

The girls stared at each other and then burst out into a simultaneous laugh. But it was excitement, not mirth, that occasioned it. Before the wild echoes had rung through the vault, the hysterical girls were tearing at the hard walls, trying in vain to dislodge a nugget.

"Oh, why did I leave that ax in the pannier!" wailed Polly.

"Isn't it always that way—when you need a thing!" exclaimed Eleanor.

In her haste to reach a fragment that looked easy to break off, Polly dropped the torch. She stooped to pick it up again and saw a nugget of the ore on the ground, half-covered with dirt.

"I've got a piece! Oh, Nolla, look! LOOK!" shouted Polly, holding aloft her treasure.

Eleanor ran over and both girls examined the chunk of yellow streaked and studded rock.

"Polly, it really looks like gold," ventured Eleanor, awed.
