After DuQuesne had made sure that the small compartment in the prow of the vessel contained nothing of use to them, the body of one of the Fenachrone was thrown carelessly into it, the air-tight bulkhead was closed and securely locked, and the chief marauder stepped into the airlock. "As soon as I get her exactly on course and velocity, I'll step out into space and you can pick me up," he directed briefly, and was gone. In the _Violet's_ engine room DuQuesne released the anchoring attractor beams and backed off to a few hundred yards' distance. He spun a couple of wheels briefly, pressed a switch, and from the _Violet's_ heaviest needle-ray projector there flashed out against the prow of the scout patrol a pencil of incredibly condensed destruction. Dunark, the crown prince of Kondal, had developed that stabbing ray as the culminating ultimate weapon of ten thousand years of Osnomian warfare; and, driven by even the comparatively feeble energies known to the denizens of the Green System before Seaton's advent, no known substance had been able to resist for more than a moment its corrosively, annihilatingly poignant thrust. And now this furious stiletto of pure energy, driven by the full power of four hundred pounds of disintegrating atomic copper, at this point-blank range, was hurled against the mere inch of transparent material which comprised the skin of the tiny cruiser. DuQuesne expected no opposition, for with a beam less potent by far he had consumed utterly a vessel built of arenak--arenak, that Osnomian synthetic which is five hundred times as strong, tough, and hard as Earth's strongest, toughest, or hardest alloy steel. Yet that annihilating needle of force struck that transparent surface and rebounded from it in scintillating torrents of fire. Struck and rebounded, struck and clung; boring in almost imperceptibly as its irresistible energy tore apart, electron by electron, the surprisingly obdurate substance of the cruiser's wall. For that substance was the ultimate synthetic--the one limiting material possessing the utmost measure of strength, hardness, tenacity, and rigidity theoretically possible to any substance built up from the building blocks of ether-borne electrons. This substance, developed by the master scientists of the Fenachrone, was in fact identical with the Norlaminian synthetic metal, inoson, from which Rovol and his aids had constructed for Seaton his gigantic ship of space--_Skylark Three_. * * * * *
