That raid was successful in that it forced the immediate return of the Sirian fleet, and very nearly destroyed the sphere. Over seventy-two thousand of the torpedo-ships were destroyed, but we lost two thousand ships and twenty thousand men. But Waterson announced that the Sirians would no longer be able to escape because of their greater acceleration. He had discovered a method for using an attractor beam of a short range but considerable power to be used with an electro-magnetic device that would automatically turn on the instruments in such a way that no matter what the accelerations might be, no matter how great, as long as they were within the limits of the ship's strength, the accelerations and centrifugal forces would be instantly neutralized, thus making possible violent maneuvers that the sudden forces had hitherto made impossible. A demonstration of his new ship had confirmed it. He took up a number of the Cabinet in his special machine, and turned hairpin turns at ten miles a second! The acceleration would have been instantaneously deadly had those neutralizers failed. They might as well have been under a half million ton freighter as it landed, as undergo those accelerations! But in that perfectly balanced room, it was not detectable. The ship's hull was made triple strength, as were the power projectors, and the generators. It was powered like a freighter, and could reach its full speed of 1,000 miles per second at an acceleration 5,000 times that of Earth's gravity. Waterson, who weighed two hundred and ten pounds on Earth would have weighed over five tons! It meant that the Solarian fleet would no longer be handicapped by the greater flexibility of the enemy ships. The plants that had been manufacturing the machines had already closed down temporarily, while the dies for these new machines were being made. But within thirty-six hours the first of the machines was being turned out.
