"Steady down, kids. We'll be QX as soon as the whistle blows—I hope."

"P-s-s-t!" Kathryn hissed. "Listen!"

"Lensmen of the Galactic Patrol!" Mentor's resonant pseudovoice filled all space. "I, Mentor of Arisia, am calling upon you because of a crisis in which no lesser force can be of use. You have been informed upon the matter of Ploor. It is true that Ploor has been destroyed; that the Ploorans, physically, are no more. You of the Lens, however, already know dimly that the physical is not the all. Know now that there is a residuum of nonmaterial malignancy against which all the physical weapons of all the Universe would be completely impotent. That evil effluvium, intrinsically vicious, is implacably opposed to every basic concept and idea of your Patrol. It has been on the move ever since the destruction of the planet Ploor. Unaided, we of Arisia are not strong enough to handle it, but the massed and directed force of your collective mind will be able to destroy it completely. If you wish me to do so, I will supervise the work of so directing your mental force as to encompass the complete destruction of this menace, which I tell you most solemnly is the last weapon of power with which Boskonia will be able to threaten Civilization. Lensmen of the Galactic Patrol, met as one for the first time in Civilization's long history, what is your wish?"

A tremendous wave of thought, expressed in millions of variant phraseologies, made the wish of the Lensmen very clear indeed. They did not know how such a thing could be done, but they were supremely eager to have Mentor of Arisia lead them against the Boskonians, whoever and wherever they might be.

"Your verdict is unanimous, as I had hoped and believed that it would be. It is well. The part of each of you will be simple, but not easy. You will all of you, individually, think of two things, and of only two. First, of your love for and your pride in and your loyalty to your Patrol. Second, of the clear fact that Boskonia must not and shall not triumph over Civilization. Think these thoughts, each of you with all the strength that in him lies.

"You need not consciously direct those thoughts. Being attuned to my pattern, the force will flow at my direction. As it passes from you, you will replenish it, each according to his strength. You will find it the hardest labor you have ever performed, but it will be of permanent harm to none and it will not be of long duration. One hour will suffice. Are you ready?"

"WE ARE READY!" The crescendo roar of thought must have bulged the Galaxy to its poles.

"Children—strike!"


The Unit struck. The outermost Eddorian screen went down. It struck again, almost instantly. Down went the second. The third. The fourth.
