"You think so, Earthling?" And a seething sphere of mental force encompassed the Tellurian's brain. Kinnison's senses reeled at the terrific impact; but he shook off the attack and smiled.

"Come again, Worsel. That one jarred me to the heels, but it didn't quite ring the bell."

"You flatter me," the Velantian declared in surprise. "I could scarcely touch your mind—could not penetrate even its outermost defenses, and I exerted all my force. But that fact gives me hope. My mind is, of course, inferior to theirs, but since I could not influence you at all, even in direct contact and at full power, you may be able to resist the minds of the Delgonians. Are you willing to hazard the stake you mentioned a moment ago? Or rather, I ask you, by the Lens you wear, so to hazard it—with the liberty of an entire people dependent upon the outcome."

"Why not? The spools come first, of course—but without you our spools would both be buried now inside the cliff of the Catlats. Fix it so that your people will find these spools and carry on with them in case we fail, and I'm your man. There—now tell me what we're apt to be up against, and then let loose your dogs."

"That I cannot do. I know only that they will direct against you mental forces such as you never even imagined. I cannot forewarn you in any respect whatever as to what forms those forces may appear to assume. I know, however, that I shall succumb to the first bolt of force. Therefore, bind me with these chains before I open the shield. Physically, I am extremely strong, as you know; therefore, be sure to put on enough chains so that I cannot possibly break free, for if I can break away I shall undoubtedly kill both of you."

"How come all these things here, ready to hand?" asked VanBuskirk, as the two patrolmen so loaded the passive Velantian with chains, manacles, handcuffs, leg irons and straps that he could not move even his tail.

"It has been tried before, many times," Worsel replied bleakly, "but the rescuers, being Velantians, also succumbed to the force and took off the irons. Now I caution you, with all the power of my mind—no matter what you see, no matter what I may command you or beg of you, no matter how urgently you yourself may wish to do so—do not liberate me under any circumstances unless and until things appear exactly as they do now and that door is shut. Know fully and ponder well the fact that if you release me while that door is open it will be because you have yielded to Delgonian force, and that not only will all three of us die, lingeringly and horribly, but also, and worse, that our deaths will not have been of any benefit to civilization. Do you understand? Are you ready?"

"I understand. I am ready," thought Kinnison and VanBuskirk as one.

"Open that door."
