Adendrohahkis was particularly well inclined toward the ape-man because of the fact that it had been the king's son, Komodoflorensal, whom Tarzan had rescued from the clutches of the Alalus woman, and so it was that everything was done to make the giant's stay among them a pleasant one. A hundred slaves brought his food to him where he had taken up his abode beneath the shade of a great tree that grew in lonely majesty just outside the city. When he walked among the group of dome-houses a troop of cavalry galloped ahead to clear a path for him, lest he trod upon some of the people of the city; but always was Tarzan careful of his hosts, so that no harm ever befell one of them because of him. As he mastered the language he learned many things concerning these remarkable people. Prince Komodoflorensal almost daily took it upon himself to assist in the instruction of his colossal guest and it was from him that Tarzan learned most. Nor were his eyes idle as he strolled around the city. Particularly interesting was the method of construction used in erecting the comparatively gigantic dome-houses which towered high above even the great Tarzan. The first step in the construction was to outline the periphery of the base with bowlders of uniform size and weighing, perhaps, fifty pounds each. Two slaves easily carried such a bowlder when it was slung in a rope hammock and as thousands of slaves were employed the work progressed with rapidity. The circular base, with a diameter of one hundred and fifty to two hundred feet, having been outlined, another, smaller circle was laid about ten feet inside the first, four openings being left in each circle to mark the location of the four entrances to the completed building and corresponding to the four principal cardinal points of the compass. The walls of the entrances were then outlined upon the ground with similar large bowlders, these being a little more carefully selected for uniformity, after which the four enclosures thus formed were packed closely with bowlders. The corridors and chambers of the first floor were then outlined and the spaces between filled with bowlders, each being placed with the utmost care and nicety in relation to those touching it and those that should rest upon it when the second course was laid, for these were to support a tremendous weight when the edifice was completed. The corridors were generally three feet wide, the equivalent of twelve feet by our standards, while the chambers varied in dimensions according to the uses to which they were to be put. In the exact center of the building a circular opening was left that measured ten feet in diameter and this was carried upward as the building progressed until the whole formed an open shaft from ground floor to roof in the completed edifice.
