38 The number of steel furnaces in the United States in 1850 was 5> all in Pennsylvania. They employed a capital of $52,300 and 40 hands, consumed materials of the value of $133>^20, and payed for labor $23100, yielding a product valued at $172,080. In i860 returns were made of 13 steel-making establishments, of which 9 were in Pennsylvania, 2 in New York, end 2 in New Jersey. Tlieir total capital amounted to $1,640,000. The number of hands was 7^8, and the cost of labor $308,736. The materials used cost $809,17b, and produced 11,838 tons of steel, valued at $1,778,240, an average of $150 per ton.(13) In i960, by way of contrast, more than 99 million short tons of steel ingots were produced. The steel industry had a capacity to produce lb8,571,000 short tons of ingots, and steel was fashioned into a lb myriad of products. Pig iron production for all of I863, at the height of the Civil War, would have occupied domestic facilities in 195b for five days, and total steel output would have taken less than one hour to produce.^ Whatever else the economy of i860 might have been, it was not an economy based heavily upon metals nor dependent upon the consumption of great quantities of mineral fuels. But conditions were particularly appropriate for the development of what has come to be called "mass production," a process dependent upon 13 Ibid., pp. cxcil-cxcvi.
