Then came the discussion of weapons. There was pitifully little to discuss. The interplanetary patrol fleet was a mere police force, designed to destroy meteors, turn comets or asteroids. There was no real naval fleet. But mechanical devices had reached a great peak of perfection and the little space ships were so cheap, so easily operated, and so eminently safe, that nearly every family had several, and new ones were always in demand. There were mighty factories to meet this demand. Twenty billion people can absorb a tremendous number of machines. That was the greatest protection we had, and it was that quantity production, developed by the American, Ford, that made Waterson's campaign possible. But we were to learn much of quantity production methods before that war was over! * * * * * Orders were issued that evening to all the great plants over all three planets to begin work on a great quantity of ten-man-high speed ships. They were to be arranged with mountings for machine guns firing explosive bullets loaded with material explosive, each one equal to 100 tons of the old fashioned Dynamite, with special mountings for Dis ray machines. The disintegration ray machinery was to be built by the companies employed ordinarily in making private power plants, hand lights, and the jumping belts. These belts had small projectors that threw a directional beam of force that tended to deform the curvature of space, at that point, and the result was a force that pulled the projector forward, for the space before it acted like a spring. If a magnet be held near a steel watch spring, the spring will bend, but it will try to straighten out and pull the magnet forward. If the magnet could pass through the spring it would progress, as the space curver apparatus was pulled through space. This was the principle of every ship now built, from these tiny two-kilogram (nearly five pounds) machines capable of lifting a man into the air, to the titanic new passenger-freight liners carrying as high as three quarters of a million tons. The principle of the disintegration ray was not greatly different, and so the machines designed for turning these out in quantities were used to make the Dis ray apparatus with no great changes. The heat ray projectors were made in quantities for every purpose, they were used for cooking, for welding metals, for warming the home, for melting down cliffs to make way for a building or a tunnel for water, for heating the mighty space ships, for anything to which heat might be applied to advantage. These would make very effective weapons but for the fact that heat rays could be reflected. They would bounce off the car of the enemy without doing any damage if it were polished, as no doubt it would be.
