"Not a fully-formulated one at all," returned Zor Ala. "But each of us is doing whatever he can to further his knowledge of the Kralon's equipment, and all of us are trying to prepare to take advantage of any opportunity which may arise in the future."

"But," objected Malherne, "even the Kralons apparently can't control the Time sector from which they get their victims. By their own admission, they are trying to gain knowledge by picking humans from as far in the future as possible. But apparently they have been only partially successful, for some of the people they have obtained are from a Time preceding mine. It seems that Gordo Lanson and Dar Mikol and you are three of the few from a period further in the future than my time."

Gordo Lanson nodded. "That is the reason for all this," he said, gesturing toward the stack of sheets on the desk. "I am attempting to formulate a method of controlling the point from which or to which the Time Trap gleans or delivers its victims. Apparently the Kralons have never accomplished that, but I think we can succeed in doing what they could not."

"May the Lord grant that to be true!" said Malherne fervently.

"I regret," said Zor Ala, "that Randall felt it necessary to make his foolhardy attempt to invade the Hive, but of course I understand and sympathize with his reasons.

"He feels entirely responsible for the passengers of the Diamvator, and considers himself obliged to attempt their rescue. However, I am very much afraid that his attempt will be ill-fated."

Lanson nodded. "The Kralons are very intelligent," he said. "And they will have no scruples whatsoever in dealing with troublesome humans. They resent the fact that their own race is to vanish from the surface of the globe in one phase of the future, and that man has supplanted them as the intelligent, governing form of life. And they intend to do something about it!"

Malherne nodded impatiently. "Yes," he said, "but what can we do now? What can we do to help Randall and the rest of my companions? And how can we prepare to use Lanson's theories concerning the Time Trap?"

Both Zor Ala and Gordo Lanson regarded the engineer understandingly. They realized his fear concerning his companions, and sympathized with his frustration in being unable to help them.

The physicist nodded toward the pile of sheets on the desk. "If you remember your calculus," he said, "you could be of great help to us by checking my figures."
