This, of course, brought up the question of what would happen if cylinder met cylinder—if the Black strategists should also have arrived at the same solution—and this question remained unanswered. Or, rather, there were too many answers, no two of which agreed; like those to the classical one of what would happen if an irresistible force should strike an immovable object. There would be a lot of intensely interesting by-products!

Even Rularion of Jove did not come up with a definite solution. Nor did Bergenholm; who, although a comparatively obscure young Lensman-scientist and not a member of the Galactic Council, was frequently called into consultation because of his unique ability to arrive at correct conclusions via some obscurely short-circuiting process of thought.

"Well," Port Admiral Kinnison had concluded, finally, "If they've got one, too, we'll just have to shorten ours up, widen it out, and pray."

"Clayton to Port Admiral Kinnison," came a communication through channels. "Have you any additional orders or instructions?"

"Kinnison to Admiral Clayton. None," the Port Admiral replied, as formally, then went on via Lens: "No comment or criticism to make, Alex. You fellows have done a job so far and you'll keep on doing one. How much detection have you got out?"

"Twelve detets—three globes of diesels. If we sit here and do nothing the boys will get edgy and go stale, so if you and Virge agree we'll give 'em some practice. Lord knows they need it, and it'll keep 'em on their toes. But about the Blacks—they may be figuring on delaying any action until we've had time to crack from boredom. What's your idea on that?"

"I've been worried about the same thing. Practice will help, but whether enough or not I don't know. What do you think, Virge? Will they hold it up deliberately or strike fast?"

"Fast," the First Lensman replied, promptly and definitely. "As soon as they possibly can, for several reasons. They don't know our real strength, any more than we know theirs. They undoubtedly believe, however, the same as we do, that they are more efficient than we are and have the larger force. By their own need of practice they will know ours. They do not attach nearly as much importance to morale as we do; by the very nature of their regime they can't. Also, our open challenge will tend very definitely to force their hands, since face-saving is even more important to them than it is to us. They will strike as soon as they can and as hard as they can."

Grand Fleet maneuvers were begun, but in a day or so the alarms came blasting in. The enemy had been detected; coming in, as the previous Black Fleet had come, from the direction of Coma Berenices. Calculating machines clicked and whirred; orders were flashed, and a brief string of numbers; ships by the hundreds and the thousands flashed into their assigned positions.

Or, more precisely, almost into them. Most of the navigators and pilots had not had enough practice yet to hit their assigned positions exactly on the first try, since a radical change in axial direction was involved, but they did pretty well; a few minutes of juggling and jockeying were enough. Clayton and Schweikert used a little caustic language—via Lens and to their fellow Lensmen only, of course—but Samms and Kinnison were well enough pleased. The time of formation had been very satisfactorily short and the cone was smooth, symmetrical, and of beautifully uniform density.
