ittle twins."

"What d'you s'pose they'd do with 'em, Bert, if they did take Flossie
and Freddie?"

"Oh, they wouldn't hurt 'em, of course. They'd just black up Flossie's
and Freddie's faces with walnut juice to make 'em look dark, like real
gypsies, and they'd keep 'em until dad paid a lot of money to get the
twins back."

"How much money?"

"Oh, maybe a thousand dollars--maybe more."

"Oh!" exclaimed Nan. "Then we must be sure never to let Flossie or
Freddie out of our sight. We've got to watch them every minute."

"Of course," agreed Bert. "We'll fool those gypsies yet."

Carrying out their plan to be very careful of their little brother and
sister, Bert and Nan took the small twins in the boat with them when
they went fishing an hour later. Bert would not go out far from the
shore of Blueberry Island--indeed, his mother had told him he must not,
for the lake was deep in places--and the older twins did about as much
watching the bushes along the bank for signs of gypsies as they did
fishing.

Flossie and Freddie, however, not worrying about any trouble, had lots
of fun tossing their baited hooks into the water, and Freddie yelled in
delight when he caught the first fish. Flossie also caught one, but it
was very small, and Bert made her put it back in the lake.

The children caught enough fish for a meal, though when they started out
neither their father nor mother thought they would. But the worms proved
to be good bait.

"We'd have caught bigger fish if we'd had my tin bugs for bait," said
Freddie.

"I don't want my bugs put on a hook," said Flossie. "When will you find
them, Freddie, and make them go around and around?"

"I don't know," he answered.

The tents were put in good order and for two or three days the children
had great sport playing, going fishing and taking walks in the woods
with their father and mother, or going for trips on the lake. There were
no more night scares.

"Maybe it wasn't gypsies after all," said Nan to her brother one day.

"Yes, it was," he said. "They were here, but they went away when they
found out we knew about them. But they'll come back, and then they may
try to take Flossie or Freddie. We've got to keep a good watch."

It was about a week after they had come to Blueberry Island that the
Bobbsey twins--all four of them--went for a ride in the goat wagon.
There was a good road which ran the whole length of the island, and
Whisker could easily pull the wagon al
