"I don't care if it is dirty, it's fun."

"You might have known, Nan," laughed Mrs. Bobbsey, "that Flossie would not object to dirt."

With a shovel for turning up the dirt, and a tin can to hold the worms, Bert and the two smaller twins were soon busy. But they did not have as good luck as they expected. Earthworms were not plentiful on the island. Perhaps they could not swim over the lake from the main shore, Freddie suggested.

"Aren't bugs good for bait?" asked Freddie, when he had looked in the tin can and found only a few worms wiggling about after more than half an hour's digging on the part of himself and Bert.

"Some kinds of bugs are good for fishing; yes," Bert answered, and, hearing that, Freddie started back for the tent where the trunks were stored.

"What are you going to do?" Bert called after his little brother.

"I'm going to get the go-around bugs. We can use them for bait. Water won't hurt 'em—the store man told me so. We can use the go-around bugs."

"Oh, they're no good—they're tin!" laughed Bert.

But Freddie was not listening. He had slipped into the tent and was searching for the toys he had bought in New York. Bert kept on digging for worms, now and then finding one, which Flossie picked up for him, until he heard another call from Freddie. The little fellow came running from the tent with an empty and broken box in his hand.

"Look! Look!" cried Freddie. "My go-around bugs comed alive in the night and they broke out of the box. Oh, dear! Now I can't have 'em to catch fish with! The go-around bugs broke out of the box and they've gone away!"
