Presently their host touched Redgrave on the shoulder and pointed to a four-wheeled car of light framework and exquisite design, containing seats for four besides the driver, or guide, who sat behind. He held out his hand to Zaidie, and handed her to one of the front seats just as an Earth-born gentleman might have done. Then he motioned to Redgrave to sit beside her, and mounted behind them. The car immediately began to move silently, but with considerable speed, along the left-hand side of the outer street, which, like all the others, was divided by narrow strips of russet-coloured grass and flowering shrubs. In a few minutes it swung round to the right, crossed the road, and entered a magnificent avenue, which, after a run of some four miles, ended in a vast, park-like square, measuring at least a mile each way. The two sides of the avenue were busy with cars like their own, some carrying six people, and others only the driver. Those on each side of the road all went in the same direction. Those nearest to the broad side-walks between the houses and the first row of trees went at a moderate speed of five or six miles an hour, but along the inner sides, near the central line of trees, they seemed to be running as high as thirty miles an hour. Their occupants were nearly all dressed in clothes made of the same glistening, silky fabric as their host wore, but the colourings were of infinite variety. It was quite easy to distinguish between the sexes, although in stature they were almost equal. The men were nearly all clothed as their host was. The colours of their garments were quieter, and there was little attempt at personal adornment, though many wore bands of an intensely bright, sky-blue metal round their arms above the elbow, and others wore belts and necklaces of links composed of this and two other metals resembling gold and aluminum, but of an exceedingly high lustre. The women were dressed in flowing garments something after the Greek style, but they were of brighter hues and much more lavishly embroidered than the men's tunics were. They also wore much more jewellery. Indeed, some of the younger ones glittered from head to foot with polished metal and gleaming stones. There was one more difference which they quickly noticed. The men's hair, like their host's, was nearly always wavy, but that of the women, especially the younger, was a mass of either natural or artificial curls, short and crisp about the head, and flowing down in glistening ringlets to their waists.
