aval people were of the opinion that she had gone down,
but others thought she had escaped to some base, which, of course, was
unknown to our authorities. We have always had a suspicion that there
was some sort of a base around here. We were cruising to-day trying to
locate it."

It was decided that the Secret Service men should take charge of
matters, and that they would sail to the nearest town on the bay so
that they might obtain additional help with which to round up all the
Germans and those in league with them.

"This will prove a very important capture," said Mr. Blarcomb, who was
the head officer of the crowd. "And you, young men, can rest assured
that you will get full credit for what you have done."

"If you don't mind, I wish you would drop us off at our camp," said
Jack. "It will save us a whole lot of tramping."

"We'll do that willingly."

It did not take the motor boat long to cover the distance to the front
of the camp where the cadets were in the habit of bathing. A few were
now in the water, and they looked in wonder at the sudden appearance
of the Rovers and Gif.

"There is Captain Dale now!" cried Jack, when they had landed and the
motor boat had gone on its way. "My! won't he be surprised at the
story we have to tell?"

"Maybe he has already heard it, from Andy and Randy and Spouter,"
suggested Gif.

But the old West Pointer had heard nothing, for the others had not yet
come in from the forest. He listened in amazement to the story the
boys had to tell.

"I would like to be at that round-up myself," he declared. "I trust
that they capture every one of the rascals." And then he added with a
smile: "This is certainly a feather in your caps, lads."

It was only a little later when the twins and Spouter came in. They,
of course, were also excited.

"Got one of the Germans and got the Secret Service men on the trail!"
declared Fred proudly.

"Good enough!" cried Andy. "But say! we have got our little story to
tell, too;" and then he and the others related what had been
discovered at the cabin in the woods.

"This certainly is important," declared Captain Dale. "Who would ever
suppose that Mr. Brown and Mr. Martell were in league with these
Germans! They certainly ought to be captured."

"And I'd like to be there when they are caught," declared Randy.

"Well, perhaps you will be," answered Captain Dale significantly.
