Within the second wall lay the royal arsenals and the deer-park, with meadows and handsome groves, and in the interior rose a third wall of great thickness, each side of which was a mile in length, while its height was twenty-five feet. This last enclosure, one square mile in area, contained the palace, which reached from the northern to the southern wall and included a spacious court. Though its roof was very lofty, it was but one story in height, standing on a paved platform of several feet elevation, from which extended a marble terrace seven feet wide, surrounded by a handsome balustrade, which the people were allowed to approach. Carved and gilt dragons, figures of warriors and animals, and battle-scenes ornamented the sides of the great hall and the apartments, while the roof was so contrived that only gilding and painting were to be seen. On each side of the palace a grand flight of marble steps ascended to the marble terrace which surrounded the building. The interior contained an immense hall, capable of serving as a banqueting-room for a multitude of guests, while the numerous chambers were all of great beauty and admirably arranged. The roof on the exterior was painted red, green, azure, and violet, the colors being highly durable, while the glazing of the windows was so neatly done that they were transparent as crystal. In the rear of the palace were arranged the treasure-rooms, which contained a great store of gold and silver bullion, pearls and precious stones, and valuable plate. Here also were the family apartments of the emperor and his wives. Opposite the grand palace stood another, very similar in design, where dwelt his eldest son, the heir to the throne. On the north side, between the palace and the adjoining wall, rose an artificial mound of earth, a hundred paces high and a mile in circuit at its base. Its slopes were planted with beautiful evergreen trees, which had been transported thither, when well grown, by the aid of elephants. This perpetual verdure gave it the appropriate name of the Green Mount. An ornamental pavilion crowned the summit, which, in harmony with the sides, was also made green. The view of the mount, with its ever-verdant trees and the richly decorated building on its summit, formed a scene delightful to the eyes of the emperor and the other inmates of the palace. This hill still exists, and is yet known by its original title of Kinshan, or the Green Mount.
