"Could any one ever have dreamt of such a lovely place?" said Zaidie, after their wondering eyes had become accustomed to the marvels about them, "and yet--oh dear, now I know what it reminds me of! Flammarion's book, 'The End of the World,' where he describes the remnants of the human race dying of cold and hunger on the Equator in places something like this. I suppose the life of poor Ganymede is giving out, and that's why they've got to live in magnified exposition buildings, poor things!" "Poor things!" laughed Redgrave. "I'm afraid I can't agree with you there, dear. I never saw a jollier-looking lot of people in my life. I daresay you're quite right, but they certainly seem to view their approaching end with considerable equanimity." "Don't be horrid, Lenox! Fancy talking in that cold-blooded way about such delightful-looking people as these, why, they are even nicer than our dear bird-folk on Venus, and of course they are a great deal more like ourselves." "Wherefore it stands to reason that they must be a great deal nicer!" he replied, with a glance which brought a brighter flush to her cheeks. Then he went on, "Ah, now I see the difference." "What difference? Between what?" "Between the daughter of Earth and the daughters of Ganymede," he replied. "You can blush, and I don't think they can. Haven't you noticed that, although they have the most exquisite skins and beautiful eyes and hair and all that sort of thing, not a man or woman of them has any colouring? I suppose that's the result of living for generations in a hothouse." "Very likely," she said; "but has it struck you also that all the girls and women are either beautiful or handsome, and all the men, except the ones that seem to be servants or slaves, are something like Greek gods, or, at least, the sort of men you see on the Greek sculptures?" "Survival of the fittest, I presume. These are probably the descendants of the highest races of Ganymede; the people who conceived the idea of prolonging the life of their race and were able to carry it out. The inferior races would either perish of starvation or become their servants. That's what will happen on Earth, and there is no reason why it shouldn't have happened here." As he said this the car swung out round a broad curve into the centre of the great square, and a little cry of amazement broke from Zaidie's lips as her glance roamed over the multiplying splendours about her. In the centre of the square, in the midst of smooth lawns and flower-beds of every conceivable shape and colour, and groves of flowering trees, stood a great domed building, which they approached through an avenue of overarching trees interlaced with flowering creepers.
