“Please say yes, Mother!” begged Bert.

“We’d like to go!” added Nan.

“Well,” answered Mrs. Bobbsey slowly, “it sounds as if it would be a nice trip. That is it will be nice if we can rescue this poor boy from the lonely island. Yes,” she said to her husband, “I think we ought to go. But it is strange that Cousin Jasper could not get any one from here to start out before this.”

“They did not believe the tale he told of the boy having been left on the island,” said Mr. Bobbsey. “They thought Cousin Jasper was still out of his head, and had, perhaps, dreamed this. He was very anxious to get some one started in a boat for the island, but no one would go. So he had to send for me.”

“And you’ll go!” exclaimed Bert.

“Yes, we’ll all go. Now that I have told you Cousin Jasper’s strange story I’ll go down and talk to the sea captain. I want to find out what sort of motor boat he has, and when we can get it.”

“When are we going to start for the island?” asked Bert.

“And what’s the name of it?” Nan questioned.

“Is it where Robinson Crusoe lived?” queried Freddie.

“I’ll have to take turns answering your questions,” said Mr. Bobbsey with a laugh. "In the first place, Bert, we’ll start as soon as we can—that is as soon as Cousin Jasper is able to leave the hospital. That will be within a few days, I think, as the doctor said a sea voyage would do him good. And, too, the sooner we start the more quickly we shall know about this poor boy.
