"Mighty low. We had about decided to hop over there after some. I want some of your textbooks on electricity and so on, too. I see you brought a load of platinum with you." "Yes, a few hundred tons. We also brought along an assortment of books I knew you would be interested in, a box of radium, a few small bags of gems of various kinds, and some of our fabrics, Sitar thought your Karfediro would like to have. While we are here, I would like to get some books on chemistry and some other things." "We'll get you the Congressional Library, if you want it, and anything else you think you'd like. Well, gang, let's go places and do things! What to do, Mart?" "We had better drop back to Earth, have the laborers unload the platinum, and load on the salt, books, and other things. Then both ships will go to the 'X' planet, as we will each want compasses on it, for future use. While we are loading, I should like to begin remodeling our instruments; to make them something like these; with Dunark's permission. These instruments are wonders, Dick--vastly ahead of anything I have ever seen. Come and look at them, if you want to see something really beautiful." "Coming up. But say, Mart, while I think of it, we mustn't forget to install a zone-of-force apparatus on this boat, too. Even though we can't use it intelligently, it certainly would be a winner as a defense. We couldn't hurt anybody through it, of course, but if we should happen to be getting licked anywhere, all we'd have to do would be to wrap ourselves up in it. They couldn't touch us. Nothing in the ether spectrum is corkscrewy enough to get through it." "That's the second idea you've had since I've known you, Dicky," Dorothy smiled at Crane. "Do you think he should be allowed to run at large, Martin?" "That is a real idea. We may need it--you never can tell. Even if we never find any other use for the zone of force, that one is amply sufficient to justify its installation." "Yes, it would be, for you--and I'm getting to be a regular Safety-First Simon myself, since they opened up on us. What about those instruments?" * * * * * The three men gathered around the instrument-board and Dunark explained the changes he had made--and to such men as Seaton and Crane it was soon evident that they were examining an installation embodying sheer perfection of instrumental control--a system which only those wonder instrument-makers, the Osnomians, could have devised. The new object-compasses were housed in arenak cases after setting, and the housings were then exhausted to the highest attainable vacuum. Oscillation was set up by means of one carefully standardized electrical impulse, instead of by the clumsy finger-touch Seaton had used. The bearings, built of arenak and Osnomian jewels, were as strong as the axles of a truck and yet were almost perfectly frictionless.
