“This has been a great summer,” said Fred enthusiastically. “There’s been something stirring every day. We have been going from one excitement to another about as fast as we could go. But now we have come to the end.”

“Oh, no,” laughed Mr. Button. “You haven’t gotten to the end by any manner of means. Go ahead boys never turn backward. I think you will find that you have still more exciting experiences before you.”

“Then we’ll go ahead and try them,” laughed John.

“But not to-night,” said Fred. “We’ll be in Mackinac in a little while.”

“It doesn’t make any difference,” declared John. “We’ll go ahead wherever we are.”

THE END
