the touch of his finger upon a second button, the propellers whirred as his hand drew back the speed lever, and Carthoris, Prince of Helium, was off into the gorgeous Martian night beneath the hurtling moons and the million stars. Scarce had the flier found its speed ere the man, wrapping his sleeping silks and furs about him, stretched at full length upon the narrow deck to sleep. But sleep did not come at once at his bidding. Instead, his thoughts ran riot in his brain, driving sleep away. He recalled the words of Thuvia of Ptarth, words that had half assured him that she loved him; for when he had asked her if she loved Kulan Tith, she had answered only that she was promised to him. Now he saw that her reply was open to more than a single construction. It might, of course, mean that she did not love Kulan Tith; and so, by inference, be taken to mean that she loved another. But what assurance was there that the other was Carthoris of Helium? The more he thought upon it the more positive he became that not only was there no assurance in her words that she loved him, but none either in any act of hers. No, the fact was, she did not love him. She loved another. She had not been abducted—she had fled willingly with her lover. With such pleasant thoughts filling him alternately with despair and rage, Carthoris at last dropped into the sleep of utter mental exhaustion. The breaking of the sudden dawn found him still asleep. His flier was rushing swiftly above a barren, ochre plain—the world-old bottom of a long-dead Martian sea. In the distance rose low hills. Toward these the craft was headed. As it approached them, a great promontory might have been seen from its deck, stretching out into what had once been a mighty ocean, and circling back once more to enclose the forgotten harbour of a forgotten city, which still stretched back from its deserted quays, an imposing pile of wondrous architecture of a long-dead past. The countless dismal windows, vacant and forlorn, stared, sightless, from their marble walls; the whole sad city taking on the semblance of scattered mounds of dead men’s sun-bleached skulls—the casements having the appearance of eyeless sockets, the portals, grinning jaws. Closer came the flier, but
