The balance of about 9,620,000 tons is produced by Chinese private or government mines and those worked by primitive methods- such as those in Lin-yu; Tsi-chow and Ching-shing (Chihli); I-hsien, Ning-yang and Po-shan (Shantung); Hsuan-yang, Chang-teh and An-yang (Honan); P'ing-hsiang (Kiangsi); Pao-tsin, (Shansi); Hsi-hsi (Fengtian); T'ung-shan (Kiangsu); Su-hsien (Anhui); Lui-yang (Hunan); Ta-yeh and Yang-hsin (Hupeh); Yu-kan (Kiangsi) Kan-ho (Heilungkiang); and Hsuan-hua (Chihli). Compared with the world's entire output, nineteen million tons constitute only one-fiftieth part of it, while the coal produced by purely Chinese mines is only one one-hundredth part.
