Jurgens turned and opened the door through which he and his companion had just come. Matt followed him through the door, Whistler bringing up the rear with a drawn weapon.

Matt was bewildered by the trend of recent events. The quickest way for getting at the nub of the difficulty was by finding Townsend, otherwise Captain Nemo, Jr., and hearing what he had to say.

But how was Matt to be sent to the surface?

That was the point which, just then, was causing him the most wonder.


[CHAPTER V.]

THROUGH THE TORPEDO TUBE.

Motor Matt was conducted along a narrow steel corridor. Two or three ruffianly looking men were passed. They were all in greasy overclothes and paid the prisoners little attention. A door finally admitted Matt and the two with him into a chamber in the very bow of the boat. Here there were a couple of torpedo tubes, although, so far as Matt could see, there were no torpedoes.

"We'll put him out of the starboard tube," said Jurgens. "Close the bow port, Whistler, and blow the water out of the tube. I'll take the gun while you're busy."

Whistler handed over the revolver and pulled a lever at the side of the chamber. Matt could hear a muffled sound as the port closed. Thereupon Whistler, by means of another lever, turned compressed air into the tube, and there came a stifled swishing sound as the water was ejected. Finally the sound ceased, and Whistler opened the breech door and stepped back.
