“Where are you going, children?” called Mrs. Bobbsey to them.
“Oh, just for a walk,” Freddie answered.
“An’ maybe we’ll see Jack,” added Flossie.
“I only wish they would, but it is too much to hope for,” said Cousin Jasper, and he looked worried.
Bert, Nan and the others stayed for some little time after lunch, sitting in the shade on the beach, and talking. They were just about to get up and once more start the search; when Flossie and Freddie came running back. One look at their faces told their mother that something had happened.
“What is it, children?” she asked.
“We—we found a big, black cave!” answered Freddie, somewhat out of breath.
“An’—an’ they’s a—a giant in it!” added Flossie, who was also breathing hard.
“A cave!” cried Mr. Bobbsey.
“What do you mean by a giant in it?” asked Cousin Jasper.
