There were apparatus for distilling water from the atmosphere,
others for manufacturing oxygen, dynamos for furnishing light to
the interior of the Annihilator, motors for working the various
small machines, and a number of other appliances.

Forward from the engine-room was a space to be used in storing
away the food supplies, and the materials necessary for generating
the force used, as well as for making a new supply of air when
needed.

Amidships was a living-room, with a plate-glass window on either
side. There was not much space to move about in it, as, owing to
the long and narrow shape of the projectile, economy of room was
enforced. Still, the place was a lengthy one, with tables and
chairs, which could be folded up out of the way when not in use.
There was provision for a library of scientific and other books,
and a piano played by electricity and brass disks, somewhat on
the order of modern player-pianos.

"What are those apertures in the sides of the living-room?" asked
Jack of Mr. Roumann, as the lad glanced over a sheet of
blue-print paper, on which was shown a plan of the projectile.

"Those," said the German, "are for the guns."

"Guns!" exclaimed Mark. "Why, they're too big for guns. They
are large enough to put a cannon through."
