Pig iron is the basis of all iron and steel manufacturing, in whatever form, and the record of production of this single article gives at least a suggestion of the growth in the other lines of the industry, the growth in production

of the finished articles ready for consumption. The pig iron production of the world in 1800 is estimated at 460,000 tons; in 1850, 4,422,000 tons; in 1895, 29,300,000 tons, and in 1903, 46,381,000 tons. The product of 1850 was thus nearly ten times as much as in 1800, that of 1895, 63 times as much, and that of 1903, 100 times as much as in 1800, while the figures for the year 1907, give a total of 50 million tons or 109 times as much as in 1800.

Great Britain was the world’s greatest pig iron producer in 1800 and in 1850. In 1800 she produced 41 per cent of the world’s pig iron, and in 1850, 50 per cent. By 1895, however, she had begun to take second place, the United States standing at the head of the list of pig iron-producing countries at that time, the product of Great Britain forming 27 per cent of the world’s total and that of the United States 32 per cent. In 1903 the United States showed a still greater lead in this industry, producing in that year 39 per cent of the world’s total product; while Germany, which held a low rank as a producer in 1800 and 1850, actually exceeded Great Britain in 1903, producing 22 per cent of the world’s total, while Great Britain produced but 19 per cent of the total. Great Britain’s production grew from 190,000 tons in 1800 to 8,935,000 tons in 1903; Germany, from 40,000 tons to 10,085,000 tons; the United States, from 40,000 tons to 18,009,000 tons; and all other countries, from 190,000 tons to 9,352,000 tons. In 1800 the United States produced but 9 per cent of the world’s pig iron; in 1903, 38 per cent; and in 1907, 41 per cent.

It will be seen from these figures that the greatest growth in the world’s pig iron production has occurred in the United States.

Turning from the comparison of growth in pig iron production in the leading iron-producing countries of the world and comparing the growth of the iron industry in the United States with that of other manufacturing industries,

we find that the development in this line has been greater than that of other leading industries. The census figures show that the value of the product of the blast furnaces, steel works and rolling mills of the United States, combined, grew from 297 million dollars in 1880 to 906 million in 1905, having thus more than trebled in value in that period, while the value of the cotton manufactures grew from 211 million to 250 million, having little more than doubled; that of the woolen and worsted manufactures, from 194 million to 308 million; lumber and timber products, from 234 million to 580 million; boots and shoes, from 166 million to 320 million; leather, from 200 million to 253 million; and flour and gristmill products, from 505 million to 713 million in the same time. In the various branches of iron and steel manufacturing there was also a remarkable growth. Foundry and modern ship products grew in value from 215 million dollars in 1880 to 800 million in 1905; structural iron work, from 3½ million to 91 million; and wire and wire work, from 19 million to 71 million.

This increase in value of the various classes of iron and steel products does not by any means show the actual increase in quantity produced, because of the fall in prices meantime. Practically all of the important classes of iron and steel products have fallen greatly in price as the quantity produced has increased. Pig iron, for example, averaged $33 per ton in 1870, and $18 per ton in 1908; steel rails, $107 per ton in 1870 and $28 per ton in 1908; bar iron, rolled, $79 per ton in 1870 and $38 per ton in 1908; and cut nails, 4.4 cents per pound in 1870 and 2.2 cents in 1908. The iron ore production in the United States grew from 3 million tons in 1870 to 52 million in 1907; pig iron, from 1.6 million tons to 26 million; and from 69 thousand tons in 1870 to 23 million tons in 1907.

Another characteristic of modern manufacturing is exemplified in the study of the iron and steel industry and the relation of capital, labor and product, as is also the concentration of industries into great establishments and groups of establishments. As has already been noted, the value of the product of the iron and steel blast furnaces, steel works and rolling mills grew from 297 million in 1880 to 906 million in 1905, having thus a little more than trebled in that time. In the same period the capital invested in these same establishments increased from 231 million dollars to 936 million; the capital having quadrupled while the product was trebling in value. During the same time the same establishments increased the number of their employes from 140,978 to 242,640, the number of employes having therefore increased but about 75 per cent while the capital was increasing 300 per cent and the value of the product about 200 per cent. The wages paid to the employes increased from 55 million dollars in 1880 to 141 million in 1905; the total wages paid having increased 156 per cent while the number of employes increased 73 per cent, indicating a marked increase in wages paid per individual.

The tendency to concentrate the production of manufactures into great establishments is also strikingly shown in the record of the iron and steel industry in the past few years. The census figures show the number of establishments in the United States in the group, “Iron and steel, including blast furnaces, steel works and rolling mills” at 1,005 in 1880, 645 in 1890, 668 in 1900, and 605 in 1905. The 1,005 establishments in 1880 produced 297 million dollars’ worth of the product; the 645 establishments in 1890 produced 431 million dollars’ worth; the 668 establishments in 1900 produced 804 million dollars’ worth; and the 605 establishments in 1905 produced 906 million dollars’ worth of the product. Thus the average production per establishment was, in round terms, in 1880, $296,000 worth; in

1890, $668,000 worth; in 1900, $1,200,000 worth, and in 1905, practically $1,500,000 worth. This gives an average product in 1905 of 5 times as much value per establishment as in 1880, while the fact that prices of 1905 were less than those of 1880 indicates that the growth in product per establishment was even greater than the above figures of value would suggest. Prices of pig iron, for example, which averaged for “No. 1 foundry” $28.48 per ton at Philadelphia in 1880, averaged but $17.88 per ton in 1905; bar iron, rolled, $62.04 in 1880 and $38.49 in 1905; steel rails, $67.52 per ton in 1880 and $28.00 per ton in 1905; and cut nails, $3.68 per keg of 100 pounds in 1880 and $2.00 per keg in 1905. It will be seen from these figures that prices in 1905 were little more than half as much as in 1880 and that the figures which give an average of five times as much value of product per establishment in 1905 as in 1880 therefore really indicate an average product of probably ten times as much in quantity per establishment in 1905 as in 1880.
