air patrol is less suspicious and alert than that above the larger metropolis where lies the palace of the jeddak. As he moved with the throng in the parklike canyon of the thoroughfare the life of an awakening Martian city was in evidence about him. Houses, raised high upon their slender metal columns for the night were dropping gently toward the ground. Among the flowers upon the scarlet sward which lies about the buildings children were already playing, and comely women laughing and chatting with their neighbours as they culled gorgeous blossoms for the vases within doors. The pleasant “kaor” of the Barsoomian greeting fell continually upon the ears of the stranger as friends and neighbours took up the duties of a new day. The district in which he had landed was residential—a district of merchants of the more prosperous sort. Everywhere were evidences of luxury and wealth. Slaves appeared upon every housetop with gorgeous silks and costly furs, laying them in the sun for airing. Jewel-encrusted women lolled even thus early upon the carven balconies before their sleeping apartments. Later in the day they would repair to the roofs when the slaves had arranged couches and pitched silken canopies to shade them from the sun. Strains of inspiring music broke pleasantly from open windows, for the Martians have solved the problem of attuning the nerves pleasantly to the sudden transition from sleep to waking that proves so difficult a thing for most Earth folk. Above him raced the long, light passenger fliers, plying, each in its proper plane, between the numerous landing stages for internal passenger traffic. Landing stages that tower high into the heavens are for the great international passenger liners. Freighters have other landing stages at various lower levels, to within a couple of hundred feet of the ground; nor dare any flier rise or drop from one plane to another except in certain restricted districts where horizontal traffic is forbidden. Along the close-cropped sward which paves the avenue ground fliers were moving in continuous lines in opposite directions. For the greater part they skimmed along the surface of the sward, soaring gracefully into the air at times to pass over a slower-going driver ahead, or at intersections, where the north and south traffic has the right of way and the east and west must rise above it. From private hangars upon many a roof top fliers were darting into the line of traffic. Gay farewells and parting
