e shock of the electricity will kill the creatures!"

"Good for you!" exclaimed Mr. Henderson. "Quick boys, everybody lend a
hand! Washington, detach the wires and run one to the bow and the other
to the stern of the ship. Then get out the boots."

In a few minutes the dynamo was ready to send a death-dealing current
through the entire ship. The professor and all the others put on the
boots, that were a part of the diving equipment. The dynamo was started
at full speed and the purring hum told that electricity of great power
was being developed.

The professor stood with his hand on a switch, ready to close the
circuit as soon as sufficient power had accumulated. Once more the
suckers backed the ship in order to give it impetus for another impact
on the stones.

Click! The professor snapped the switch shut. There was a burst of
bluish-green flame, and the movement of the boat suddenly ceased.

"I guess that does for 'em!" shouted Andy.

"Wait a few minutes," advised the professor. "The suckers may not all be
dead yet!"

He kept the current flowing throughout the length of the ship for
several minutes, and then turned it off.

"Now to see if the plan worked," he said. The windows in the cabin were
eagerly scanned.

"Hurrah!" cried Mark. "The suckers have gone!"

"I guess the electricity killed them," spoke Mr. Henderson. "We will
venture out now in our diving suits and see what sort of a place we are
in."

Soon the adventurers were arrayed in the heavy suits. Under them they
wore thick clothing, and in each suit was placed a small flat heater,
operated by a storage battery. The heaters were made of coils of fine
wires, and the electric current, meeting with much resistance in passing
through them, heated the coils, so there was considerable warmth.

It was all needed as they found when they felt the water entering the
diving chamber, for the fluid was as cold as an ocean full of icebergs
could make it. Protected however by the heavy suits, warm clothing and
the heaters the divers were fairly comfortable.

The outer door was opened and they all started back in amazement at the
sight which met their eyes. Before them lay a forest of real trees, with
bushes growing among them, while the ground, instead of being like the
usual ocean bed was covered with grass.

As Washington had said, on getting a small view of the place from the
little window, it was real land under water.

Their first surprise at the str
