The entrance through which he caught his first glimpse of the interior was rather beautifully carved in geometric designs, and within the walls were similarly treated, though as he proceeded from one apartment to another he found also the figures of animals, birds, and men taking their places among the more formal figures of the mural decorator's art. Stone vessels were much in evidence as well as ornaments of gold and the skins of many animals, but nowhere did he see an indication of any woven fabric, indicating that in that respect at least the Ho-don were still low in the scale of evolution, and yet the proportions and symmetry of the corridors and apartments bespoke a degree of civilization. The way led through several apartments and long corridors, up at least three flights of stone stairs and finally out upon a ledge upon the western side of the building overlooking the blue lake. Along this ledge, or arcade, his guide led him for a hundred yards, to stop at last before a wide entrance-way leading into another apartment of the palace. Here Tarzan beheld a considerable concourse of warriors in an enormous apartment, the domed ceiling of which was fully fifty feet above the floor. Almost filling the chamber was a great pyramid ascending in broad steps well up under the dome in which were a number of round apertures which let in the light. The steps of the pyramid were occupied by warriors to the very pinnacle, upon which sat a large, imposing figure of a man whose golden trappings shone brightly in the light of the afternoon sun, a shaft of which poured through one of the tiny apertures of the dome. "Ko-tan!" cried Dak-lot, addressing the resplendent figure at the pinnacle of the pyramid. "Ko-tan and warriors of Pal-ul-don! Behold the honor that Jad-ben-Otho has done you in sending as his messenger his own son," and Dak-lot, stepping aside, indicated Tarzan with a dramatic sweep of his hand. Ko-tan rose to his feet and every warrior within sight craned his neck to have a better view of the newcomer. Those upon the opposite side of the pyramid crowded to the front as the words of the old warrior reached them. Skeptical were the expressions on most of the faces; but theirs was a skepticism marked with caution. No matter which way fortune jumped they wished to be upon the right side of the fence. For a moment all eyes were centered upon Tarzan and then gradually they drifted to Ko-tan, for from his attitude would they receive the cue that would determine theirs. But Ko-tan was evidently in the same quandary as they--the very attitude of his body indicated it--it was one of indecision and of doubt.
