"What's the matter—crab get you?" asked Bob, with a chuckle.

"No. Hush!" whispered Sammy.

"What's up now?" asked Frank. "See some of those pirates?"

Sammy turned and came back to his chums.

"Easy!" he cautioned. "Fellows, I think I have a clue! Come over here, but don't make any noise."

He led them to a clump of bushes beside the path. Cautiously parting the leaves, to make an opening, Sammy looked through. Then he drew back his head.

"Yes, he's there yet!" he whispered. "Take a look."

"Who is it?" asked Bob.

"Someone digging for pirate gold!" whispered Sammy, hoarsely.
