mischief, that the father did it this time.

"Oh, the turtle will eat him up! The turtle will eat Freddie up!" cried
Flossie.

Freddie, too, after the first shock of surprise, was frightened, and as he
clung with both hands to the edges of the turtle's shell he looked over
his shoulder, toward his father and the others, and cried:

"Oh, get me out, Daddy! Get me out!"

The cries of the children, and the call of Mr. Bobbsey, had drawn a crowd
around the turtle pool, and among the throng were some of the attendants
on duty in the Aquarium.

"What's the matter?" asked one, elbowing his way through the crowd to the
side of Mr. Bobbsey, who was trying to climb over the rail to go to the
rescue of his little boy.

"Freddie fell in," explained Bert. "He's on the back of the big turtle!"

"Good land!" cried the man. "What will happen here next? Come back, sir,"
he went on to Mr. Bobbsey, "I'll get him out for you."

"Then please be quick. He may fall off and the turtle may bite him or
drown him," said Freddie's father.
