"Many birds with one stone!" Haynes chuckled gleefully. "You will have a short reprieve, friends, while I take care of these intruders, whoever they are. I can't use too great a gravity on them at first. It might warn them, if they notice that their ships are accelerating too rapidly. They might as well be part of my 'accident', even if they do happen to be police. The Space Patrol has accidents now and then, just like anybody else!"

Haynes started to work the manual controls of the generator. The area in which he and his several aides stood, was shielded against the greater attraction, having been thus arranged by us for testing purposes. The shrill hum of the machines grew louder.

I felt the weight of my prone body increase suffocatingly. The heat increased too, as the great coils, gleaming in the glow of illuminators, gradually absorbed more power. And I knew that, out in space, those slender fingers of force were reaching and strengthening, invisible and treacherous. Our unknown friends were doomed.

Not only were they doomed, but our whole idea was destined to failure. The dream that Nick had died for. The vast progress that it meant. Worlds out here—worlds with largely a self-sufficient production—real colonization. Fair play. Norman Haynes would resist all that, because progress would weaken his power here. He was master of the asteroids, because he was master of their imports and exports. And unless he could control the rejuvenated asteroids himself, they would never be. With him directing, they would not represent a real improvement—only another means of robbing from the colonists. And colonists weren't rich.

I could see those same thoughts, that gouged savagely into my own brain, burning in Geedeh's cat eyes, where he sprawled near me. Being a Martian, born to a lesser gravity than the terrestrial, he was suffering more than I—physically. But perhaps my mental torture was worse. Geedeh was Irene's friend, but I loved her. She was gone—lost somewhere—maybe dead. That, for me, was the worst—much worse than that crushing weight.

I couldn't let things remain the way they were! My seething fury and need lashed me on, even in my helplessness. God—what could I do? I tried to figure something out. Could I break the gravity machinery some way? Impossible, now, certainly!

I tried to remember my high school physics. Principles that might be used to give warning signals, and so forth. And just what that awful gravity would do to things.

Close to me was the base of the domelike crystal shell that covered the gravity generator. It wasn't a vital part, certainly, just stout quartz. But it was the only thing I could reach. As I lay there on the floor, I drew my foot back, doubling my knee. I stamped down against the quartz with all my strength. The first blow cracked it. The second drove my metal-shod boot-heel through with a crashing sound. A small hole, eighteen inches long, was made in the barrier. The sounds of the great machinery went on as before. The gravity kept slowly increasing. Geedeh, suffering more, now, looked at me puzzledly. Pa Mavrocordatus stared anxiously. And Norman Haynes at the surface phone laughed unpleasantly.

"Cracking up, eh, Wallace?" he sneered. "I know who your would-be helpers on those space ships are, now. I suppose I should be surprised at their identities. They're calling to you. Want to listen? My men above have locked this surface phone to our ship radio."
