It was 8:25 (12:13 A.M. Earth Time) when our trim, swift flier rose from the landing stage on the roof of The Warlord's palace. Thuria and Cluros were speeding across a brilliant starlit sky casting constantly changing double shadows across the terrain beneath us that produced an illusion of myriad living things in constant, restless movement or a surging liquid world, eddying and boiling; quite different, John Carter told me, from a similar aspect above Earth, whose single satellite moves at a stately, decorous pace across the vault of heaven.

With our directional compass set for Duhor and our motor functioning in silent perfection there were no navigational problems to occupy our time. Barring some unforeseen emergency, the ship would fly in an air line to Duhor and stop above the city. Our sensitive altimeter was set to maintain an altitude of 300 ads (approximately 3000 feet), with a safety minimum of 50 ads. In other words, the ship would normally maintain an altitude of 300 ads above sea level, but in passing over mountainous country it was assured a clearance of not less than 50 ads (about 490 feet) by a delicate device that actuates the controls as the ship approaches any elevation of the land surface that is less than 50 ads beneath its keel. I think I may best describe this mechanism by asking you to imagine a self-focusing camera which may be set for any distance, beyond which it is always in focus. When it approaches an object within less distance than that for which it has been adjusted it automatically corrects the focus. It is this change that actuates
