"Right you are, ace--that's a sound idea. But say, Dunark, it wouldn't be good technique for you to eat our food for any length of time. While we're figuring this out you'd better hop over there and bring over enough to last you two until we get you home. Give it to Shiro--after a couple of lessons, you'll find he'll be as good as any of your cooks." * * * * * Faster and faster the _Skylark_ flew, pulling behind her the mass of wreckage, held by every available attractor. When the calculated velocity had been attained, the attractors were shut off and the vessel darted away toward that planet, still in the Carboniferous Age, which possessed at least one solid ledge of metallic "X," the rarest of all earthly metals. As the automatic controls held the cruiser upon her course, the six wanderers sat long in discussion as to what should be done, what could be done, to avert the threatened destruction of all the civilization of the Galaxy except the monstrous and unspeakable culture of the Fenachrone. Nearing their destination, Seaton rose to his feet. "Well, folks, it's like this. We've got our backs to the wall. Dunark has troubles of his own--if the Third Planet doesn't get him the Fenachrone will, and the Third Planet is the more pressing danger. That lets him out. We've got nearly six months before the Fenachrone can get back here...." "But how can they possibly find us here, or wherever we'll be by that time, Dick?" asked Dorothy. "The battle was a long way from here." "With that much start they probably couldn't find us," Seaton replied soberly. "It's the world I'm thinking about. They've got to be stopped, and stopped cold--and we've got only six months to do it in.... Osnome's got the best tools and the fastest workmen I know of...." his voice died away in thought. "That sort of thing is in your department, Dick." Crane was calm and judicial as always. "I will, of course, do anything I can. But you probably have a plan of campaign already laid out?" "After a fashion. We've got to find out how to work through this zone of force or we're sunk without a trace. Even with rays, screens, and ships equal to theirs, we couldn't keep them from sending a vessel to destroy the earth; and they'd probably get us too, eventually. They've got a lot of stuff we don't know about, of course, since I took only one man's mind. While he was a very able man, he didn't know all that all the rest of them do, any more than any one man has all the earthly science known. Absolutely our only chance is to control that zone--it's the only thing they haven't got. Of course, it may be impossible, but I won't believe that, until I've exhausted a lot of possibilities. Dunark, can you spare a crew to build us a duplicate of that Fenachrone ship, besides those you are going to build for yourself?" "Certainly. I will be only too glad to do so."
