"That last outburst of Sitsumi's explains a lot of the reported activity in the Lake Baikal region, beyond the Gobi," swiftly dropped from Jeter's lips. "The materials which Sitsumi uses in the preparation of his light-ray-bending substance are found near there somehow. And that means that the Japanese guards--which may be Eurasian guards, after what Sitsumi told us--and employees of this unholy crowd, are easily engaged in the preparation of other space ships." "Does this thing seem to have any armament?" asked Eyer. Jeter signified negation with a swift movement of his head. "Their one weapon seems to be the apparatus which causes that ray. You know, the ray which lifts buildings, pulling them up by the roots." "Have you any idea what it is?" "Yes. That last stuff of the Three which you translated for me gives me a clue. At first I thought that they had perfected some substance, perhaps with unknown electrical properties, which nullified gravity. But that won't prove out. If the ray simply nullified gravity, the buildings down there, while weightless, would not rise as they did. They might sway if somebody breathed against them. A midget might lift one with his finger; but they wouldn't fly skyward as they did--and do!" For a moment the partners ceased their whispering and talked together naturally to disarm suspicion. The fact that the space ship and its ruthless denizens still engaged in the awful work of devastation was amply being proved. In the main room it was possible, through the use of telescopes and audiphones--set into the walls so that they were invisible, yet enabled any one in the room to see everything, and hear everything that transpired on the far earth below--to keep close watch on the work of the destroyers. Anything close enough could be seen with the naked eye through the walls of the globe. * * * * * Now the space ship was systematically destroying buildings the length and breadth of Manhattan Island. The river-front buildings were destroyed in a single sweep, from north to south, of the ghastly ray. Farther back from the Hudson, however, after the water-front buildings had been reduced to mere piles of rubble, the most beautiful, most modern buildings were left standing. "Can't you just imagine those beautiful structures filled with the monsters created by the genius of Sitsumi and the Three--and their as yet unknown lieutenants back at Lake Baikal?" Eyer gritted his teeth. His hands closed atop the table at which they were seated. The knuckles went white with the strain. The lips of both men were white. They realized to the full the dreadful responsibility which they had assumed. They knew how abysmally hopeless was their chance of accomplishing anything. And without some gigantic effort being made, the world as they knew it would be destroyed. In its place would be a race of strange beings, of vengeful hybrids endowed from birth with the will to conquer, or destroy utterly.
