Now, beyond the buildings in the foreground they could see the tops of giant structures in the distance, their great white walls showing resplendent in the clean atmosphere and bright sunlight. It was certain that they were entering a very large city. They afterward learned that this city, called Parang, was next to the largest one on Mars, having a population more than four million souls. * * * * * Little conversation passed between Robert and the professor as they both eagerly studied the mysteries of Martian life passing before their eyes. Neither could yet quite bring himself to a full realization of the fact that they were actually viewing life upon the planet which had caused so much conjecture upon Earth. “I wonder whether we shall pull in on the ‘elevated’ or the ‘subway,’” grinned Robert. His question was answered a few minutes later as they plunged into the darkness of a tunnel. For ten minutes or more they roared swiftly through the darkness, dimly illuminated by the incandescents in the ceiling of their car. Then they emerged suddenly into a vast, brilliantly lighted underground chamber, filled with the din of noisy bustle, and came to a stop before a large barred area. Here their hosts politely signified that they should get out. News of their arrival had probably preceded them. A great, curious crowd thronged the area. Half of their body of guides led the way through one of the gates, forcing a passage for them through the dense, curious crowd. It was here that Robert caught his first sight of the Martian women. Unconsciously he was expecting to find the golden-haired type of his dream. But in this he was disappointed, for, without exception, they were dark-haired, and with complexions of a pale, olive tint, as were the men. The women’s garments did not differ greatly from those of their men folk, in that they wore a variety of loose trousers like those worn by our Turkish women. Perhaps their garb is best described by stating that it was strikingly similar to that, of the women in the Mohammedan harems, without the face veil. Passing through a massive archway, they walked up a few steps leading into a large waiting room not unlike one of ours. Through the throng they continued and entered a roomy elevator which whisked them upward. Emerging from this they found themselves once more in the daylight, and in a great vestibule leading to the street. Outside, several closed conveyances waited, evidently engaged by prearrangement. Robert and Professor Palmer entered one of these with two of their beaming hosts, sinking down into the luxurious upholstering gratefully. As they rolled along, Robert and the professor studied the scenes around them in suppressed excitement.
