"Still, that's not the question just now, and if you are in a hurry to circumnavigate the moon we'd better begin to get a wriggle on us as they say down yonder; so come below and we'll shut up. A bit later I'll show you something that no human eyes have ever seen." "What's that?" she asked as they turned away towards the companion ladder. "I won't spoil it by telling you," he said, stopping at the top of the stairs and taking her by the shoulders. "By the way," he went on, "I may remind your Ladyship that you are just now drawing the last breaths of earthly air which you will taste for some time, in fact until we get back. And you may as well take your last look at earth as earth, for the next time you see it it will be a planet." She turned to the open window and looked over into the enormous void beneath, for all this time the _Astronef_ had been mounting swiftly towards the zenith. She could see, by the growing moonlight, vast, vague shapes of land and sea. The myriad lights of New York and Brooklyn were mingled in a tiny patch of dimly luminous haze. The air about her had suddenly grown bitterly cold, and she saw that the stars and planets were shining with a brilliancy she had never seen before. Redgrave came back to her, and laying his arm across her shoulder, said: "Well, have you said goodbye to your native world? It is a bit solemn, isn't it, saying goodbye to a world that you have been born on; which contains everything that has made up your life, everything that is dear to you?" "Not quite everything," she said, looking up at him--"at least I don't think so." He lost no time in making the only reply which was appropriate under the circumstances; and then he said, drawing her close to him: "Nor I, as _you_ know, darling. This is our world, a world travelling among worlds, and since I have been able to bring the most delightful of the daughters of Terra with me, I, at any rate, am perfectly happy. Now, I think it's getting on to supper time, so if your Ladyship will go to your household duties, I'll have a look at my engines and make everything snug for the voyage." The first thing he did when he left the conning-tower was to hermetically close every external opening in the ship. Then he went and carefully inspected the apparatus for purifying the air and supplying it with fresh oxygen from the tanks in which it was stored in liquid form. Lastly he descended into the lower hold and turned on the energy of repulsion to its fullest extent, at the same time stopping the engines which had been working the propellers.
