Starting next morning at daylight, at three in the afternoon the party entered Pekin. The relief was great to leave the sandy, dusty road for one of the paved ways which radiate from the city. The first sight of the city struck the travelers as the most grandiose spectacle of the Celestial Empire. In front rose a high tower, with a five-storied roof of green tiles, pierced with five rows of large portholes, from which grinned the mouths of cannon; while to the right and left, as far as could be seen, stretched the gigantic wall surrounding the city, built partly of granite and partly of large gray bricks, with salients, battlements and loopholes, wearing a decidedly martial air. This impression was somewhat modified, however, by the discovery that the grinning cannons were made of wood. The entrance was under a vaulted archway, through which streamed a converging crowd of Chinese, Mongols, Tartars, with their various costumes, together with blue carts, files of mules and caravans of heavily-loaded camels. Pekin was built by Kublai-Khan about 1282, near the site of an important city which dated from the Chow dynasty, or some centuries before the Christian era. The city covers an enclosed space about twenty miles in circumference. It is rectangular in form, and divided into two parts, the Chinese and the Tartar cities. The walls of the Tartar city are the largest and widest, being forty to fifty feet high, and, tapering slightly from the base, about forty feet wide at the top. They are constructed upon a solid foundation of stone masonry resting upon concrete, while the walls themselves are built of a solid core of earth, faced with massive brick: the top is paved with tiles, and defended by a crenelated parapet. Bastions, some of which are fifty feet square, are built upon the outside at distances of about one hundred feet. There are sixteen gates, seven of which are in the Chinese town, six in the Tartar town, and three in the partition wall between these two. In the centre of the Tartar city is an enclosure, also walled, called the Imperial City, and within this another, called the Forbidden City, which contains the imperial palaces and pleasure-grounds. Broad straight avenues, crossing each other at right angles, run through the whole city, which in this respect is very unlike other Chinese towns. A stream entering the Tartar city near its north-west corner divides into two branches, which enter the Imperial City and surround the Forbidden City, and then uniting again pass through the Tartar and Chinese towns, to empty in the Tung-Chau Canal.
