aid Billy.

Dorothy had scrambled to the top of the big rock. Suddenly she uttered a
loud screech.

"What's bit you now?" demanded Chet, starting up.

"Oh! my trophy pin! It's dropped off my blouse directly into the water.
Oh, dear me! I won that in the relay races this spring."

"And the water's deep there," declared Bobby. "It's a regular diving
hole."

"Now, you've lost it!" cried Dora, sadly. "But you can wear mine
sometimes."

"Don't you fret, Miss--which is it, Dora, or Dorothy?" demanded Billy.

"I'm Dorothy," admitted the twin in question, climbing sadly down to the
shore again.

"That's all right, Dorothy," said Short and Long. "Leave it to me. I put
my bathing trunks in my pocket and while you girls are spreading the
luncheon over yonder I'll dive and see if I can get the pin. It's some
muddy down there, I guess; but I can stay under water nearly two
minutes--can't I, Chet?"

"So you have, Billy. You try it. And if you can't, maybe Lance or I can
get it."

Billy retired into the nearest cave to remove his clothing and the girls
returned to the landing. In five minutes Billy made a famous dive into
the deep hole under the boulder. He did not stay down two minutes, for
Lance timed him. And he came up without the pin, but when he got his
breath, he gave voice to a shout that started the echoes.

"What's the matter with you, Billy?" demanded Chet.

"I've found it!" cried the small boy.

"Good! give it to me and I'll run with it to Dorothy," said Lance.

"Oh! I haven't found her old pin," said Billy.

"What's the matter with you, then?" demanded Chet. "You said you'd found
it."

"And so I have," proclaimed the diver.

"Then hand it over," said Lance.

"But it's down there--and it's hitched to a chain," gasped Billy.

"What are you talking about?" cried both his boy friends together.

"_I've found the lard can!_" shrieked Billy, dancing up and down on the
rock.

"Great Scott!" spoke Chet, staring at him.

"You don't mean it?" cried Lance.

"The lard can with the money?" demanded Chet, shaking the smaller boy by
the arm.

"How do I know whether there is money in it or not?" returned Billy.
"Lemme find where the end of that chain is hitched, and we'll drag it
out of the mud and see."

"Say! Talk about treasure hunting!" gasped Lance. "This beats 'em all!"

Splash! went Billy again into the water, like a huge frog. In a minute
he was at the surface again, with the end of a trace chain
