“I’ll tell you what it is, boys,” said Bart at last; “I think I know how to get something; We passed a place down on the shore where there were lots of mussels. Tom, you come along with me, and Phil can go with Arthur. Bruce may watch here.”

This plan was eagerly adopted; and as there was no time to lose, the boys set out. Fortunately, the place spoken of by Bart was not far away, and fortunately, too, the rocks were covered with shell-fish of different kinds, and the hollows of the rocks filled with them. Tom and Bart heaped them into their handkerchiefs.

“Hallo!” cried Bart, suddenly, in a joyous tone. “See here, Tom.”

“What?”

“Come here.”

Tom went, and found Bart plunging his hands most vigorously into a pool of water, which the retreating tide had left in a rocky hollow.

“What have you got there?”

“I call them shrimps,” said Bart, holding one up in his hands. “They’re rather small, though. Go about and hunt up another hole.”

Tom went off, and in a short time called to Bart in a loud voice.

Bart started up.
