As soon as he could see again he stared around at the landscape. The enormous scarlet desert extended everywhere to the horizon, excepting where it was broken by the oasis. It was roofed by a cloudless, deep blue, almost violet, sky. The circle of the horizon was far larger than on earth. On the skyline, at right angles to the direction in which they were walking, appeared a chain of mountains, apparently about forty miles distant. One, which was higher than the rest, was shaped like a cup. Maskull would have felt inclined to believe he was travelling in dreamland, but for the intensity of the light, which made everything vividly real. Joiwind pointed to the cup-shaped mountain. “That’s Poolingdred.” “You didn’t come from there!” he exclaimed, quite startled. “Yes, I did indeed. And that is where we have to go to now.” “With the single object of finding me?” “Why, yes.” The colour mounted to his face. “Then you are the bravest and noblest of all girls,” he said quietly, after a pause. “Without exception. Why, this is a journey for an athlete!” She pressed his arm, while a score of unpaintable, delicate hues stained her cheeks in rapid transition. “Please don’t say any more about it, Maskull. It makes me feel unpleasant.” “Very well. But can we possibly get there before midday?” “Oh, yes. And you mustn’t be frightened at the distance. We think nothing of long distances here—we have so much to think about and feel. Time goes all too quickly.” During their conversation they had drawn near the base of the hills, which sloped gently, and were not above fifty feet in height. Maskull now began to see strange specimens of vegetable life. What looked like a small patch of purple grass, above five feet square, was moving across the sand in their direction. When it came near enough he perceived that it was not grass; there were no blades, but only purple roots. The roots were revolving, for each small plant in the whole patch, like the spokes of a rimless wheel. They were alternately plunged in the sand, and withdrawn from it, and by this means the plant proceeded forward. Some uncanny, semi-intelligent instinct was keeping all the plants together, moving at one pace, in one direction, like a flock of migrating birds in flight.
