"Those long thin white lines in South America are the tops of the Andes, and the big, dark patches to the right of them are the forests and plains of Brazil and the Argentine. Not a bad way of studying geography, is it? If we stopped here long enough we should see the whole earth spin right round under us, but we haven't time for that. We shall be in the moon before it's morning in New York, but we shall probably get a glimpse of Europe to-morrow." Zaidie stood gazing for nearly an hour at this marvellous vision of the home-world which she had left so far behind her before she could tear herself away and allow her husband to shut the slides again. The greatly diminished weight of her body destroyed the fatigue of standing almost entirely. In fact, on board the _Astronef_ just then it was almost as easy to stand as it was to lie down. There was of course very little sleep for the travellers on this first night of their wonderful voyage, but towards the sixth hour after leaving the earth, Zaidie, overcome as much by the emotions which had been awakened within her as by physical fatigue, went to bed, after making her husband promise that he would wake her in good time to see the descent upon the moon. Two hours later she was awake and drinking the coffee which he had prepared for her. Then she went on to the upper deck. To her astonishment she found, on one hand, day more brilliant than she had ever seen it before, and on the other hand darkness blacker than the blackest earthly night. On the right was an intensely brilliant orb, about half as large again as the full moon seen from the earth, shining with inconceivable brightness out of a sky black as midnight and thronged with stars. It was the Sun; the Sun shining in the midst of airless Space. The tiny atmosphere enclosed in the glass-domed deck-space was lighted brilliantly, but it was not perceptibly warmer, though Redgrave warned her not to touch anything upon which the sun's rays fell directly, as she might find it uncomfortably hot. On the other side was the same black immensity which she had seen the night before, an ocean of darkness clustered with islands of light. High above in the zenith floated the great silver-grey disc of earth, a good deal smaller now. But there was another object beneath them which was at present of far more interest to her. Looking down to the left, she saw a vast semi-luminous area in which not a star was to be seen. It was the earth-lit portion of the long familiar and yet mysterious orb which was to be their resting place for the next few hours. "The sun hasn't risen over there yet," said Redgrave, as she was peering down into the void. "It's earth-light still. Now look at the other side."
