Next to the engine room was the kitchen. It contained an electric
range and all necessary appliances and utensils for preparing meals.
There were lockers and a large reserve storeroom which when the time
came would be well stocked with food. Forward of the kitchen was the
living and dining room. It contained comfortable seats, folding tables

how the various machines were working. There were gages, pointers and
dials, which told the direction the ship was traveling, the speed and
the distance above the earth or below the surface. Similar indicators
were in the conning tower, which had a powerful search light.

The ship was lighted throughout by incandescent lamps, and there was
even a small automatic piano worked by the electric current, on which
popular airs could be played.

If the gas and the gravity neutralizer worked as Professor Henderson
hoped they would, as soon as the ship was completed, all that would be
necessary to start on the voyage would be to fill the aluminum bag and

The gas was made from common air, chemically treated and with a secret
material added which by means of a complicated machine in a measure
did away with the downward pull of the earth. Thus all that was
necessary to carry on a long voyage was a quantity of gasolene to
operate the engine which worked the electric machines, and some of
this secret compound.

The professor and his helpers had been working to good advantage. At
