“You mean the one on the Hassen?” queried a reporter. “He was—a few days after you left him. He was picked up, the vessel towed to this harbor, and he got big salvage money. Most of the passengers and crew were also saved.”

“Good!” cried Jerry. “Now give ’em our yarn, boys.”

And that it was a “yarn” well worth telling may well be believed. Columns of it were printed.

“Oh! what a time we’ve had!” cried Jerry, when he and his chums finally reached home, and were received by their tearful parents, who had almost given up hope.

“Yes, it was tough part of the time, but I’m not sorry we went through it,” spoke Ned. “I only wish we could get that submarine—or one like it—and make other trips.”

“Well, we’ll be sure to do something more—soon,” said Bob. “We’ve got to keep active!”

“Indeed—you’ll do nothing more for a long while!” cried his mother.

But the boys were destined for other adventures, and what they were will be related in the next volume of this series, to be called “The Motor Boys on Road and River; Or, Racing to Save a Life.”

The two elderly Germans left the submarine as soon as it was docked in Boston Harbor. They said they were going back to their native land. They had had enough of under-water life, they declared.
