“Have you a boat?” asked Jerry, quickly.

“Certainly, although I use it but sparingly, and then only at night.”

The hermit led the way to the lower end of the island. Here in a water-cave rested a long, round-bottomed row boat, containing two pairs of oars.

“Just the thing!” cried Jerry. “Come on, Harry!”

He and his chum leaped in. Blumpo looked at his newly found father.

“I will go along if you wish,” said the hermit.

In five seconds more all four were in the boat, which was then shoved out into the lake.

With Jerry and Harry at the oars, they made good progress in the direction of Si Peters’ yacht.

All were armed, and Blumpo occupied the time in seeing that every weapon was ready for use.

“The wind is dying out,” said Harry. “That is in our favor.”
