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.
"You were speaking of the levitating ray," prompted Eyer with swift change to the sidewise whispering.
"From what you heard I'm sure it is something invented by Liao Wu, Yung Chan and Wang Li. In so much they have an advantage over Sitsumi. I doubt if there is any love lost among them, beyond the fact that they need one another. Sitsumi is master of the substance which bends light rays—and thus is rendered invisible, while the Three are masters of the ray which not only propels this space ship, but is the agency by which buildings are torn up, dropped and destroyed. It's plain to me that this room is the control room of the space ship. The ray is—well, it's as difficult to explain as electricity, and perhaps as simple in its operation. The ray does more than nullify gravity—can be made to reverse gravity! Let's call the ray the gravity inverter for want of a better name. It makes anything it touches literally fall away from the Earth, toward the point whence the ray emanates!"
"And if we were to obtain control of the apparatus which harnesses the ray?"
"We lack the knowledge of the Three for its operation. No, we've got to find some simpler solution in the brief time we have."
At this point the partners had been within the white globe about ten hours and they had learned much about it. The inner globe, for example, maintained an even keel, no matter how the space ship as a whole moved on its rays that seemed like table legs. The gyroscopic principle was used. The inner globe was movable within the outer globe, or rind. If for any reason the space ship listed in one direction or the other, the inner globe, while it rose and fell naturally, remained upright, its floor always level so that, the gyroscope controlling the whole, the central, levitating, ray would always, must always, as it proved, point downward.
Try as they might, the partners could not see how the Three manipulated the ray. They guessed that there were many buttons on the table at which they sat. The table itself was not an ordinary table. What might have been called a fifth leg, squarely under the center of the table, was about three feet square. Through this, Jeter guessed, ran the wires by which they controlled all their activities, machinery to operate which had been installed under the floor in the unseen lower half of the inner globe.
