The general reader who looks for the first time into the matter is likely to be staggered by what statistics seem to say. Apparently they contradict what he is accustomed to hear from popular economists about the waste of war. He has been told in the newspapers that business is undermined by the withdrawal of great numbers of men from "productive" consumption of the fruits of labor and their engagement as soldiers in "unproductive" consumption. But, to his astonishment, he finds that the statistics of 1861-1865 show much increase in Northern business --as, for example, in 1865, the production of 142 million pounds of wool against 60 million in 1860. The government reports show that 13 million tons of coal were mined in 1860 and 21 million in 1864; in 1860, the output of pig iron was 821,000 tons, and 1,014,282 tons in 1864; the petroleum production rose from 21 million gallons in 1860 to 128 million in 1862; the export of corn, measured in money, shows for 1860 a business of $2,399,808 compared with $10,592,704 for 1863; wheat exporting showed, also, an enormous increase, rising from 14 millions in 1860 to 46 millions in 1863. There are, to be sure, many statistics which seem to contradict these. Some of them will be mentioned presently. And yet, on the whole, it seems safe to conclude that the North, at the close of the third year of war was producing more and was receiving larger profits than in 1860.
