² The cash (chʼien) was the money of account, and the string its multiple of one thousand. In 738 A.D., 277,000 strings of one-cash bronze coins were minted (Wang Ying-lin, Yü Hai [Chʼeng-tu Wang Shih ed.], 180/23a. Cited hereafter as YH). In 806 A.D., the receipts from the silver tax amounted to 12,000 liang (Hsiu, Ou-yang, Chʼi, Sung, and others, Hsin Tʼang-shu [Shanghai, 1884], 54/7aGoogle Scholar. Cited hereafter as HTS). This figure represents no more than 10 per cent of the total output of silver (Shigeru, Katō, Tō-sō jidai ni okeru kin-gin no kenkyū [Tōkyō: Toyo Bunkō, 1926], p. 534)Google Scholar. The market price of silver in 938, the earliest extant, was 680 cash a liang (ibid., p. 473). Consequently, 81,600 strings of cashʼ worth of silver were produced each year in the middle of the eighth century, bringing the total annual increment in the supply of money to 358,000,000 cash.

⁴ More than six million strings of cashʼ worth of coins were minted yearly in the 1080's (Sung Hui-yao Chi-kao [Shanghai, 1936]Google Scholar, “Shih Huo,” 11/2a-3a, 6a, 8a-9a, 55/19a.

Hereafter cited as SS). By the eleventh century, a major use of gold was as a medium of exchange (Katō Shigeru, pp. 273–83). In 1078, the output of gold was 76,000 ounces, or 55,790 liang (SHY:SH, 33/7a-7b, 27a-29b), nearly twice the average annual yield of New World mines between 1503 and 1660 (Earl Hamilton, J., American Treasure and the Price Revolution in Spain, 1501–1650 [Cambridge: Harvard University Press, 1934], p. 42)CrossRefGoogle Scholar, and greater than the 70,000 ounces produced in Europe each year at the beginning of the sixteenth century (Soetbeer, Adolf, Edelmetall-Production und Werthverhältniss zwischen Gold und Silber seit der Entdeckung America's bis zur Gegenwart [Gotha, 1879], p. 107)Google Scholar. The price of gold from 1015 to the end of the eleventh century remained fairly stable at 10,000 cash a liang (Katō Shigeru, p. 473). Consequently, the value of gold output in 1078 was 557,900 strings of cash. The price of silver in 1076 was 1,500 cash per liang (Kaisaburō, Hino, “Gin, Ken no jukyu-jo hori mita Godai Hokusō no sai-hei, sai-shi,” Tōyō Gakuhō, XXXV [Sept. 1952], 8–9)Google Scholar. Consequently, the value of silver output in 1078 was 2,586,338 strings of cash, and the annual increment in the supply of money was about 9,174,238 strings of cash.

⁵ The price of rice in North China markets was 425 cash a U. S. standard bushel in 1075 (Tao, Li, Hsü Tzu-chih-tʼung-chien Chʼang-pien [Chekiang, 1881]Google Scholar, 265/5b-6a. Hereafter cited as HCP).

⁶ The population of China in 742 was slightly over 52.5 million. In calculating this total, I have used the data presented in HTS, pp. 37–43, corrected by comparisons with the statistics in Hsü, Liu, Chiu Tʼang-shu (Shanghai: Tʼung-wen shu-chü, 1884), 38–41Google Scholar. In 1078, there were about 16.5 million households in the Sung empire (HCP, 295/13b; Tsʼun, Wang, Yuan-feng chiu-yü chih ***[Wu-ying-tien, 1899 ed.], passim)Google Scholar. According to contemporary estimates, each household averaged five individuals (e.g., SHY:SH, 24/10b).

⁷ The calculations in this paragraph are based on rough data to be ultimately used in a more refined study on money, prices, and wages in China, ca. 620–1100 A.D. The argument represents a crude application of the techniques developed by Milton Friedman for using monetary data to reconstruct national income growth (“Monetary Data and National Income Estimates,” Economic Development and Cultural Change, IX [Apr. 1961], 267–86)Google Scholar. It should be emphasized that the data only suggest the possibility of growth in real per capita income. There is no way to make even a wild guess about changes in velocity; and a good proportion of the increased stock of money was certainly used in transactions transferred from the subsistence to the exchange sector of the economy.

⁹ This figure is based on the total output of iron, copper, lead, and tin reflected in the mountain-and-marsh tax (shan-tse shui) list in SHY:SH, 33, and the “annual monopoly receipt tax” (sui-kʼo) list in Tuan-lin, Ma, Wen-hsien tʼung-kʼao (Chekiang, 1882–1896), 18Google Scholar: hereafter cited as TK. Although the mountain-and-marsh tax list is not dated, the report comes from the Kuo-chʼao hui-yao and uses circuit names only established in 1059, indicating that the statistics were collected between 1059 and 1077 (for dating of the various hui-yao see Chung, Tʼang, Sung Hui-yao yen-chiu [Shanghai: Commercial Press, 1932])Google Scholar. General surveys were made of the mining industry in 997; in 1021 (TK, 18/27a; HCP, 97/20a-21b); in 1049–53 (HCP, 97/20a-21b; TK, 18/24b-26a, 28a-28b; SS, 185/11a-11b); in 1064–67 (TK, 18/27b-28a, 28a-28b; SS, 185/13a); in 1074 (SHY:SH, 33/3b-4b), and in 1078 (SHY:SH, 33/12b-14a).

Since both the 1074 and 1078 surveys were limited to the sui-kʼo paying units, the only logical date for the mountain-and-marsh lists is 1064–67. The total receipts from the taxes on iron in 1064–67 equal the national total sui-kʼo receipts listed in TK, 18/28a-28b, plus the total mountain-and-marsh iron tax returns (SHY:SH, 33/27a-29b). At the 10 per cent rate (Hartwell, Robert, “A Revolution in the Chinese Iron and Coal Industries during the Northern Sung, 960–1126 A.D.,” Journal of Asian Studies, XXI [Feb. 1962], p. 155 n.)Google Scholar, this reflects a total production of pig iron per year in 1064–67 of 90,400 tons. The annual output of copper in 1067 was 93,000 tons (TK, 18/28a-28b; SHY:SH, 33/27a-29b). This figure assumes a tax rate of 20 per cent. Although Katō Shigeru, pp. 527–28, says that the rate on the base metals was 10 per cent during the Northern Sung, SHY:SH, 34/20b implies that it was 20 per cent on copper before 1085. Otherwise the calculations are the same as above. The output of lead was 65,000 tons (SHY:SH, 33/27a-29b; TK, 18/28b) and of tin, 48,500 tons (ibid.).

In 997, pig-iron prices of 19.77, 25.55, and 34.98 cash a pound—an average of 26.77 cash a pound—are recorded for three Szechwan prefectures (Ting Fu-pao, hsia-pien/226a-226b). The average price of rice in Szechwan, 998–1003, was 4.24 cash a pound (Chʼi, Han, Chung nsien Han Wei-wang An-Yang Chi [Chou-chin Tʼang ed.], 50/15bGoogle Scholar; Chen, Fan, Tung-chai chi-shih [Shanghai: Ts'ung-shu chi-chʼeng, 1936]Google Scholar, chüan 4, p. 24). In 1080, pig iron sold at 19.77 cash a pound in Hsing-chou (Tʼao, Lü, Ching-te chi [Wu-ying-tien, 1899 ed.], 4/12a)Google Scholar, while the average price of rice in Szechwan between 1077 and 1086 was 11.20 cash a pound (Lü Tʼao, 1/2a; Chih, Liu, Chung-su chi [Wu-ying-tien, 1899 ed.], 5/12a)Google Scholar. In 1074. iron cost 15.21 cash a pound in Shensi (HCP, 256/16a-16b), while the average price of rice in North China in 1074 was 11.22 cash a pound (HCP, 251/26b).

Besides Tegengren, this statement is based on a careful study of everything published by the Geological Survey of China, and all other available reports, periodicals, and books written over the past one hundred years which discuss iron reserves in the territory of China formerly governed by the Sung emperors. For a list of Sung iron-mining sites, see Hartwell, “Iron and Industrialism” (cited in n. 8), pp. 178–95.

¹⁶ In 1078, the Ku-chen smelter at Wu-an hsien reported an annual yield of 12,812 tons of pig iron (see n. 35). By the Chʼien-lung period (1736–1795) of the Chʼing dynasty (1644–1911), the only reminder of the once flourishing industry at Wu-an was a stone tablet on the ore hill of Hung-shan stating that iron could be made from the rock (Tegengren, p. 334). From the Opium War to the establishment of the Communist regime in 1949, it would appear that not one ounce of iron was produced in this district. In addition to Tegengren, pp. 315, 333, this statement is based on a thorough survey of all publications on Chinese mining published during the past century, including the documents in Academia Sinica, Institute of Modern History, Kʼuang-wu tang (Taipei, 1960)Google Scholar, 8 vols. The important Li-kuo deposits which are later discussed (pp. 44–45) were probably not worked after the twelfth century. Between 1126 and 1883, Chinese sources are silent about these deposits. In the latter year, Chʼing provincial officials—citing Su Tung-pʼoʼs Sung memorial discussing the wealthy thirty-six enterprises at Li-kuo—leased the mines to merchants, but work was soon abandoned owing to financial difficulties caused by the Franco-Chinese War (1883–85).

¹⁷ For example, ores from important deposits at Ta-yeh, which were converted into 148,424 tons of pig iron in 1922, were only smelted into 347 tons in 1078.

Trade between outlying ports of course may take place, but it is that between the metropolitan town and the rest of the area that dominates all. This is chiefly the exchange of the raw products of the country for the manufactured or imported goods of the town. The prices of all goods sent to the metropolitan center are ‘made’ there, or, in other words, prices diminish as the distance from the center is increased.”

The mountain-and-marsh tax receipts reflect an output of 6,937 tons, which was probably produced, in the main, at Li-chʼeng in Hsiang-chou, Lin-lü (Lin) hsien where the government offices had been closed in 1055 (Hung-pʼan, Hsü, Fang-yü kʼao-teng-kao [Chi-ning Fan-shih Hua-chin-chien-kʼo ed., 1932], 29/20b-21aGoogle Scholar; SHY:SH, 33/27a-29b). If the output of the Pan-yang yeh-wu at Hsiang-chou, Lin-lü (Lin) hsien was only the average of 1,300 tons, then the minimum output for the district would be 35,175 tons. SHY:SH, 33/3b-4a.

³⁶ From 2,002 to 14,280 tons at Li-kuo and 2,600 tons at Ta-tʼung chien. The mountain-and-marsh tax statistics were collected in the period from 1064 to 1067 (TK, 18/28a-28b; SHY:SH, 33/27a-29b). At this time, the output of the works at Ta-tʼung chien was taxed as sui-kʼo, and consequently was not included in the mountain-and-marsh tax returns. The chien was abolished before 1074 to 1077, and consequently the output was also not included in the sui-kʼo returns for 1074 to 1077 or 1078 (SHY:SH, 33/12b-14a). We must interpolate in order to estimate probable production. The output of a works administered by a yeh, or smelter office, averaged 1,300 tons annually, and each yeh probably collected taxes from several smelters. Since Ta-tʼung chien administered two yeh, 2,600 tons would seem to be a fair estimate of average annual output, 1074–1078. The Ta-tʼung office administered an eastern and a western smelter (SHY:SH, 33/3b-4a).

The sui-kʼo receipts for Li-kuo chien, reflecting an annual output of 2,002 tons (SHY:SH, 33/12b-14a), are probably incomplete. This would not be unlikely. In at least eight instances out of a total of thirty-five entries, the sui-kʼo figures are completely missing from the listing of quota and receipts reflecting output from 1075 to 1078 (SHY:SH, 33/12b-14a). Evidence concerning the industry at Tʼung-shan during the seven years following the sui-kʼo receipt list of 1078 suggests that the combined output of Li-kuo and Ta-tʼung was much higher than our estimated 4,602 tons. This might have been an increase owing to the adoption of coal after the discovery at Pai-tʼu chen (see p. 51). But it seems hardly likely that such a revolution as a two- or threefold increment could take place within such a short period of time. The annual rate of growth of the smelters included in the quota and 1078 lists was no more than 2.7 per cent between 1077 and 1078, and probably somewhat less, since the quota figure is an average of output in 1075, 1076, and 1077 (Kaisaburō, Hino, “Hokusō jidai ni okeru dō-tetsu no sanshutsu-gaku ni tsuite,” Tōyō Gakuhō, XXII [1934], 109–10Google Scholar; SHY:SH, 33/12b-14a). If 2.7 per cent continued to be the annual rate of growth for all the smelters at Li-kuo Yi, at the estimated output of 4,602 tons in 1078, then the yield by 1085 would still be only about 5,655 tons. But this figure is certainly too low. In 1083, an iron-coin mint, Pao-feng chien, was established at Hsü-chou (Tʼung-shan) to cast 200,000 strings of two-cash iron coins a year (HCP, 356/15b). This number of coins required 2,340 tons of pig iron (HCP, 344/5a), and this quota was apparently estimated on the basis of the sui-kʼo returns for 1078, i.e., 10 per cent of what was supposed to be total output. In 1084, another mint, Pao-feng hsia chien, was established with a similar quota (HCP, 344/5a; 345/9a), bringing the anticipated consumption of iron for casting iron coins alone to 4,680 tons—or 78 tons more than our estimated yield in 1078. But coinage was not the only market supplied by the smelters at Li-kuo Yi during these years. In addition to Kaifeng, the products of Lai-wu and Li-kuo foundries were transported to general arsenals (Tu-tso-yüan) at Tʼung-shan (Hsü-chou), Lin-tzu (Chʼing-chou) and Tung-pʼing (Yün-chou), as well as to branch arsenals (Hsiao-tso-yüan) in other prefectures (HCP, 339/11b; TK, 18/32a). Agricultural implements were manufactured at the foundries to supply the needs of farmers in Shantung (ibid.), and siderurgical products were transported from Li-kuo to Kaifeng, Hopei, and even Korea (Shih, Su, Tung-pʼo chʼi chi [Pao-hua huicheng li-ming chʼeng-hua, 1909]Google Scholar, “Tsou-i,” 2/9b; 13/9a-9b; “Hsü-cni,” 11/21a). Moreover, the structure of enterprise at individual foundries also suggests a much higher output. Each of the thirty-six smelters employed over one hundred men full time to mine the ore, gather the fuel, and run the furnaces (ibid., 2/10a; 11/21b). One furnace man could produce 15 metric tons of iron a year, one miner could dig 30 tons of ore, and one collieryman could dig 60 tons of coal during the early years of the twentieth century with equipment similar to that in use during the Sung (Torgasheff, Boris P., “Mining Labor in China,” Chinese Economic Journal, VI [April 1930], 511, 515, 522)Google Scholar. Assume that the efficiency of labor was not much different in mining coal and in producing charcoal. A blast furnace obtained one ton of pig iron from 2.5 tons of ore and 3 tons of fuel (Tegengren, pp. 327, 338–39). Consequently, one furnaceman, 1.25 ore miners, and .75 charcoal workers, or three men would be necessary to produce 15 metric tons of pig iron a year. One hundred workmen could produce five hundred tons a year. An estimate of smelter output based on the probable equipment of the average enterprise yields a comparable figure. Before 1078, charcoal was the primary fuel (Su Shih, “Tsou-i,” 2/10a; “Shih,” 10/11b-12a), and the crucible process was probably limited to anthracite furnaces at the larger centers during the Sung (see p. 51). Moreover, the coal discovered at Pai-tʼu chen in 1078, and subsequently used in Li-kuo furnaces, was bituminous (see n. 92) and unsuitable for use in the crucible process. Small blast furnaces had a capacity to produce .5 tons of pig iron per diem, while the larger shaft furnaces yielded 1.3 to 1.4 tons daily (see p. 53). During the work year of three hundred days (HCP, 276/13a), one small furnace could produce 150 tons, and a large furnace up to 420 tons. The generally advanced character of enterprise at this district suggests that the shaft furnaces were probably used (see pp. 45 ff.). If the average of 500 tons, 150 tons, and 420 tons (357 tons) is taken as the yield of the typical smelter, then the total output at Li-kuo chien was possibly 12,852 metric tons or 14,280 short tons in 1078, a reasonable figure in light of the evidence presented in this note.

³⁷ The mountain-and-marsh tax receipts probably reflect the output of Chin-ling chen (Tzu-chʼuan) and smaller enterprises near Lai-wu that were taxed by subprefectural rather than industrial prefectural authorities (SHY:SH, 33/12b-14a; 27a-29b). At the beginning of the Sung, iron ore and loadstone were mined at Hsi-shan, which was about twenty-three miles north of the seat of Szechwan hsien (Yüeh Shih, 19/3b), almost the exact location of the deposits reported at Chin-ling chen by modern writers such as Richthofen and Tegengren (Tegengren, p. 141). Anthracite from Hung-shan (ibid.) was probably used to smelt the ore here, as was certainly the case in the eighteenth century (Chang Tʼing-tsʼai and Chang Wu-to, Tzu-chʼuan hsien chih [1776], 1/42a-43b). For a description of Sung iron mining at Lai-wu, see Yüeh Shih, 21/12a-16a.

⁴⁹ Native furnaces in early twentieth-century China ranged in per diem capacity from 0.065 tons (Tegengren, p. 355), 0.13 (ibid.), 0.17 (ibid., p. 326), 0.24 (ibid.), 0.34 (ibid., pp. 320, 326), 0.40 (ibid., p. 339), 0.47 (ibid., p. 334), 0.48 (ibid., p. 326), 0.50 (ibid., p. 339; Wertime, p. 48), 0.68 (Tegengren, p. 337), 1.3 (ibid., pp. 333–34; Wertime, p. 55), and 1.4 (ibid.). The big difference is between the crucible-stall and small blast furnaces with daily heats of less than 0.68 tons and the larger shaft furnaces with capacities of nearly one and one-half tons per diem. The latter were never used in seasonal enterprises similar to those at Teng-chou. It would take one small blast furnace, operating full time at a per diem capacity of 0.5 tons, 44 days to yield the 22.2 tons reported for Teng-chou in 1078. This was also approximately the maximum time that a furnace could be operated without being closed down for repairs (Tegengren, p. 354). We get a similar result if we calculate on the basis of the efficiency of labor. The average per diem output of a worker (mining ore, gathering charcoal, and running the furnaces) was 0.017 tons a day (see n. 36). Eighteen households were engaged in the Teng-chou iron industry (Pao Chʼeng, 7/17a). The average number of adult males per household in Teng-chou in 1102 was 2.13 (Hope Wright, Geographical Names in Sung China [Paris: Ecole Pratique des Hautes Etudes, 1956], p. 157). The thirty-eight male workers would require over thirty-four days of steady effort to produce 22.2 tons. An increase in the number of furnaces would not materially alter the time required to yield this amount of iron with the labor force at hand.

According to Needham, this is “co-fusion steel,” and the process is ancestral to that of Sieman-Martins. Wertime argues that “Needham's leap from Chinese interfusion to the modern Sieman-Martins process seems technically and geographically unjustified.” In any case, the Chinese achieved the same goal—the conversion of high-phosphorus iron (i.e., non-Bessemer iron) into steel.

¹³⁴ Coal could have been used by the smith for working up the finished product, or it could have been used for a preliminary roasting of the iron stone. But the absence of readily available wood fuel or anthracite in the immediate vicinity of the smelting works suggests that bituminous coal was used in actually smelting the ore.
