"There is one thing that I believe you can do," Eight put in. "Your barrier wall should be able to free me from this intolerable condition of eternal life!" And he hurled himself forward with all his prodigious force against that nullifying wall. Instantly the screen flamed into incandescence; converters and generators whined and shrieked as hundreds of pounds of power uranium disappeared under that awful load. But the screens held, and in an instant it was over. Eight was gone, disrupted into the future life for which he had so longed, and the impregnable wall was once more merely a tenuous veil of sixth-order vibrations. Through that veil Seaton's projection crept warily; but the inhuman, monstrous mentality poised just beyond it made no demonstration. "Eight committed suicide, as he has so often tried to do," One commented coldly, "but, after all, his loss will be felt with relief, if at all. His dissatisfaction was an actual impediment to the advancement of our entire group. And now, feeble intellect, I will let you know what is in store for you, before I direct against you forces which will render your screens inoperative and therefore make further interchange of thought impossible. You shall be dematerialized; and, whether your minds are strong enough to exist in the free state, your entities shall be of some small assistance to me before you pass on to the next cycle of existence. What substance do you disintegrate for power?" "That is none of your business, and since you cannot drive a ray through this screen you will never find out!" Seaton snapped. "It matters little," One rejoined, unmoved. "Were you employing pure neutronium and were your vessel entirely filled with it, yet in a short time it would be exhausted. For, know you, I have summoned the other members of our group. We are able to direct cosmic forces which, although not infinite in magnitude, are to all intents and purposes inexhaustible. In a brief time your power will be gone, and I shall then confer with you again." * * * * * The other mentalities flashed up in response to the call of their leader, and at his direction arranged themselves all about the far-flung outer screen of the _Skylark_. Then from all space, directed inward, there converged upon the space ship gigantic streamers of force. Invisible streamers, and impalpable, but under their fierce impacts the defensive screens of the Terrestrial vessel flared into even more frenzied displays of pyrotechnic incandescence than they had exhibited under the heaviest beams of the superdreadnought of the Fenachrone. For thousands of miles space became filled with coruscantly luminous discharges as the uranium-driven screens of the _Skylark_ dissipated the awful force of the attack.
