other boys from nearby cottages joined with them, so the three chums became the leaders of a regular "pirate band."
One afternoon, however, something happened that put a stop to this fun. Sammy and his two chums had gone alone to the cave, and they had taken with them shovels to enlarge it, as it was getting too crowded on account of so many boys wanting to enter it.
"We'll make a dandy big cave, while we're at it!" boasted Sammy.
The three chums dug away for some time, and finally Bob said:
"That's enough, fellows. If we go too far back, and the sand should cave in, we'd never get out."
"That's right," chimed in Frank.
"Pooh! You fellows are scared!" exclaimed Sammy. "I'm going to dig it farther back. You two get some driftwood, and pile it out in front. We'll have a roaring big fire to-night."
Frank and Bob went up and down the beach, gathering sticks, and bits of broken boards, while Sammy continued to dig away inside the cave. Frank and Bob made several trips to and fro, and the pile of wood was growing.
Finally, as they neared the cave, on what they said would be their last trip, as they were tired, Frank cried:
"Look! The sand has caved in!"
"So it has!" exclaimed Bob.
They looked toward where the mouth of the cave had been, It was closed, and the sand was still sliding somewhat, showing that the accident must have happened only a little while before.
"And Sam—Sammy!" gasped Bob.
"He's in there!" faltered Frank.
"And we've got to get him out—quick!" cried Bob.
