The government maintains a number of courier roads, which, like the main trade roads, keep approximately to a straight line. These courier roads are sometimes cut in the steep sides of mountains or run through them in tunnels. They are, in the plains, 20 to 25 ft. wide and are occasionally paved. The chief courier roads starting from Peking go to Sze-chu'en, Yun-nan, Kweilin (in Kwang-si), Canton and Fu-chow. Canals are numerous, especially in the deltas of the Yangtsze and Si-kiang.
In the centre and south of China the roads are rarely more than 5 ft. broad and wheeled traffic is seldom possible. Bridges are generally of stone, sometimes of wood; large rivers are crossed by bridges of boats. In the north carts drawn by ponies, mules or oxen are employed; in the centre and south passengers travel in sedan-chairs or in wheelbarrows, or ride on ponies. Occasionally the local authorities employ the corvée system to dig out the bed of a canal, but as a rule roads are left to take care of themselves.
_Posts and Telegraphs._--Every important city is now connected by telegraph with the capital, and the service is reasonably efficient. In 1907 there were 25,913 m. of telegraph lines. Connexion is also established with the British lines in Burma and the Russian lines in Siberia. The Great Northern Telegraph Company (Danish) and the Eastern Extension Telegraph Company (British) connect Shanghai by cable with Hong-Kong, Japan, Singapore and Europe. An imperial _postal service_ was established in 1896 under the general control of the maritime customs.[25] By an edict of November 1906 the control of the postal services was transferred to the Board of Communication. The Post Office serves all the open ports, and every important city in the interior. There were in 1910 some 4000 native post-offices, employing 15,000 persons, of whom about 200 only were foreigners. The treaty powers however, still maintain their separate post offices at Shanghai, and several other treaty ports for the despatch and receipt of mails from Europe. During the years 1901-1908 mail matters increased from ten millions to two hundred and fifty-two millions of items; and the 250 tons of parcels handled to 27,155 tons. In postal matters China has adopted a most progressive attitude. The imperial post conforms in all respects to the universal Postal Union regulations. (G. J.; X.)
