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 admonitions mingled with the whirring of motors and the subdued noises of the city.
Yet with all the swift movement and the countless thousands rushing hither and thither, the predominant suggestion was that of luxurious ease and soft noiselessness.
Martians dislike harsh, discordant clamour. The only loud noises they can abide are the martial sounds of war, the clash of arms, the collision of two mighty dreadnoughts of the air. To them there is no sweeter music than this.
At the intersection of two broad avenues Vas Kor descended from the street level to one of the great pneumatic stations of the city. Here he paid before a little wicket the fare to his destination with a couple of the dull, oval coins of Helium.
Beyond the gatekeeper he came to a slowly moving line of what to Earthly eyes would have appeared to be conical-nosed, eight-foot projectiles for some giant gun.
In slow procession the things moved in single file along a grooved track. A half dozen attendants assisted passengers to enter, or directed these carriers to their proper destination.
Vas Kor approached one that was empty. Upon its nose was a dial and a pointer. He set the pointer for a certain station in Greater Helium, raised the arched lid of the thing, stepped in and lay down upon the upholstered bottom. An attendant closed the lid, which locked with a little click, and the carrier continued its slow way.
Presently it switched itself automatically to another track, to enter, a moment later, one of the series of dark- mouthed tubes.
The instant that its entire length was within the black aperture it sprang forward with the speed of a rifle ball.
There was an instant of whizzing--a soft, though sudden, stop, and slowly the carrier emerged upon another platform, another attendant raised the lid and Vas Kor stepped out at the station beneath the centre of Greater Helium, seventy-five miles from the point at which he had embarked.
Here he sought the street level, stepping immediately into a waiting ground flier. He spoke no word to the slave sitting in the driver's seat. It was evident that he had been expected, and that the fellow had received his instructions before his coming.
Scarcely had Vas Kor taken his seat when the flier went quickly into the fast-moving procession, turning presently from the broad and crowded avenue into a less congested street. Presently it left the thronged district behind to enter a section of small shops, where it stopped before the entrance to one which bore the sign of a dealer in foreign silks.
Vas Kor entered the low-ceiling room. A man at the far end motioned him toward an inner apartment, giving no further sign of recognition until he had passed in after the caller and closed the door.
Then he faced his visitor, saluting deferentially.
"Most noble--" he commenced, but Vas Kor silenced him with a gesture.
"No formalities," he said. "We must forget that Iam aught other than your slave. If all has been as carefully carried out as it has been planned, we have no time to waste. Instead we should be upon our way to the slave market. Are you ready?"The merchant nodded, and, turning to a great chest, produced the unemblazoned trappings of a slave. These Vas Kor immediately donned. Then the two passed from the shop through a rear door, traversed a winding alley to an avenue beyond, where they entered a flier which awaited them.
Five minutes later the merchant was leading his slave to the public market, where a great concourse of people filled the great open space in the centre of which stood the slave block.
The crowds were enormous to-day, for Carthoris, Prince of Helium, was to be the principal bidder.
One by one the masters mounted the rostrum beside the slave block upon which stood their chattels.
Briefly and clearly each recounted the virtues of his particular offering.
When all were done, the major-domo of the Prince of Helium recalled to the block such as had favourably impressed him.
For such he had made a fair offer.
There was little haggling as to price, and none at all when Vas Kor was placed upon the block. His merchant-master accepted the first offer that was made for him, and thus a Dusarian noble entered the household of Carthoris.
