“If I knew what an equilibrimotor is I might be in a better position to judge the merits of the plan,” I replied. “However, I am satisfied to abide by the judgment of Gor Hajus. I can assure you, Bal Zak, of our great appreciation, and as Gor Hajus has put the stamp of his approval upon your plan I can only urge you to arrange that we may put it into effect with as little delay as possible.” “Good!” exclaimed Bal Zak. “Come with me and I will conceal you until I have lured the watchman to the jetan game within my cabin. After that your fate will be in your own hands.” We followed him from the ship on to the deck of the landing stage and close under the side of the Vosar opposite that from which the watchman must approach the ship and enter it. Then, bidding us good luck, Bal Zak departed. From the summit of the landing tower I had my first view of a Martian city. Several hundred feet below me lay spread the broad, well-lighted avenues of Toonol, many of which were crowded with people. Here and there, in this central district, a building was raised high upon its supporting, cylindrical metal shaft; while further out, where the residences predominated, the city took on the appearance of a colossal and grotesque forest. Among the larger palaces only an occasional suite of rooms was thus raised high above the level of the others, these being the sleeping apartments of the owners, their servants or their guests; but the smaller homes were raised in their entirety, a precaution necessitated by the constant activities of the followers of Gor Hajus’ ancient profession that permitted no man to be free from the constant menace of assassination. Throughout the central district the sky was pierced by the lofty towers of several other landing stages; but, as I was later to learn, these were comparatively few in number. Toonol is in no sense a flying nation, supporting no such enormous fleets of merchant ships and vessels of war as, for example, the twin cities of Helium or the great capital of Ptarth.
