easily. "Bring the boat here."

Clambering aboard, he directed the casting of the anchor overboard. Then,
poising himself at the bow, he made a strong dive, vanishing under the
water.

"What's he going to do now?" asked Mr. Melville, curiously.

"I'd rather wait than guess," smiled Mr. Farnum.

For just an instant Don Melville looked, as he felt, green with envy.

Some moments passed. Then, not far from the spot where the "Pollard" had
gone down, her conning tower appeared once more. That was followed by
the emergence of the platform deck and upper hull above the water. In
another moment the tower manhole was opened, and Jack Benson, with a wave
of the hand, stepped out, his bathing suit changed for his uniform. He
lifted his cap in a joyous salute to those on shore.

"By Jove, Jack, but you're a wonder!" shouted Mr. Farnum across the water.
"I'll have Dave Pollard excited when I write him about this thing. But
you have me guessing how the trick was done."

Once more Benson signaled the small boat in close, after the anchor had
been lifted. Now, the young submarine captain came in to shore.

"You come on board with me, Mr. Farnum?" invited Jack.

"Are you going to show him how you worked the trick?" demanded Mr.
Melville, quickly.
