"When you've done that, I want you and your Velantians to design something that will scramble all the pirates' communicator beams in space, from here to the near rim of the galaxy. If you can fix things so that they can't talk, any more than we can, it'll help a lot, believe me!" "QX, chief, we'll give it the works." And the radio man called for tools, apparatus and electricians. Then throughout the great space port the many Velantians and the handful of patrolmen labored mightily, side by side, and to very good effect indeed. Slowly, the port became ringed about by, and studded everywhere with, monstrous mechanisms. Everywhere there were projectors: refractory-throated demons ready to vomit forth every force known to the expert technicians of the patrol. There were absorbers, too, backed by their bleeder resistors, air gaps, ground rods, and racks for discharged accumulators. There, too, were receptors and converters for the cosmic energy which was to empower many of the devices. There were, of course, atomic motor generators by the score, and battery upon battery of gigantic accumulators. And Nelson's high-powered scrambler was ready to go to work. These machines appeared crude, rough, unfinished; for neither time nor labor had been wasted upon nonessentials. But inside each one the moving parts fitted with micrometric accuracy and with hair-spring balance. All, without exception, functioned perfectly. At Worsel's call, Kinnison climbed up out of a great beamproof pit, the top of whose wall was practically composed of tractor-beam projectors. Pausing only to make sure that a sticking switch on one of the screen-dome generators had been replaced, he hurried to the heavily armored control room, where his little force of fellow patrolmen awaited him. "They're coming, boys," he announced. "You all know what to do. There are a lot more things that we could have done if we'd had more time, but as it is we'll just go to work on them with what we've got." And Kinnison, again all brisk captain, bent over his instruments. In the ordinary course of events the pirate would have flashed up to the planet with spy rays out and issuing a peremptory demand for the planet to show a clean bill of health or to surrender instantly such fugitives as might lately have landed upon it. But Kinnison did not--could not--wait for that. The spy rays, he knew, would reveal the presence of his armament; and such armament most certainly did not belong to this planet. Therefore, the instant that the pirate ship came within range of his detectors he acted; and forthwith everything happened at once, with furious swiftness.
