It was built of stone he did not know, as he found when he came down to the broad, paved esplanade before it. But the substance seemed to be between a marble and an onyx, so nearly as he could judge. It stretched for the best part of an earth-mile and housed the entire working force of the Aphur government as he came to know in the following days. Now, however, he gave more attention to his immediate surroundings--the vast towers on either side of the monstrous entrance, heavy and imposing and each flanked by guardian figures of what seemed winged dogs, whose front legs supported webbed membranes from body to paw. Croft passed between them through the entrance where flowed counter streams of Palosians, on foot or dashing past in gnuppa-drawn chariots, trundling on two wheels, and driven by men clad in cuirasses and belted with short swords. He entered a vast court, surrounded by colonnades, reached by sloping inclines and stairs and paved with a dull red stone. Here stood more of the chariots before the doors of this or that office of state. Blue porters moved about it, sprinkling the pavement with cooling streams of water from metal tanks strapped to their shoulders and fitted with a curved nozzle and spraying device. It made a splendid picture as the sun struck down on the red floor, the gaily trapped gnuppas, the metal of the chariots and the flashing armor on the bodies of those who rode them, or the men at arms who stood here and there about the court, armed with sword and spear. This was the heart of Aphur's life, Croft thought, gave it a glance, and set off in quest of Aphur's king. * * * * * He passed through vast chambers of audience, of council, or banqueting and reception, as he judged from the furnishing of each place. He passed other courts, marveling always at the blending of grace with strength in the construction of the whole. Also, he marveled at the richness of the draperies with which various rooms and doorways and arches were hung. Much of it seemed to possess a metallic quality in texture. It seemed like thin-spun gold. Yet it was everywhere about the palace as he passed. Finally he paused. He was getting nowhere. He decided there was but one means of attaining his desire. He put it into force. He _willed_ himself into the presence of Jadgor without further search. Thereafter he was in a room, where, beside a huge wine-red table, two men sat. The one was Prince Lakkon, whom he knew. The other was even a larger man--heavy set, dark of complexion, with grizzled hair, and a mouth held so tightly by habit that it gave the impression of lips consciously compressed. His eyes were dark as those of a bird. His nose high and somewhat bent at the middle of the bridge. The whole face was that of a man of driving purpose, who would brook small hindrance between himself and a predetermined goal.
