The data for this highly important subject are unsatisfactory. In “Estimated Valuation of National Wealth” under the head of “ Manufacturing Machinery, Tools and Implements” it is said: “For 1900 and 1904 data for the value of manufacturing machinery, tools and implements were secured from the reports of the census of manufactures. The census of 1910, based on the operations of 1909, did not, however, show these values separately, but included them with capital, so that it was necessary to prepare the estimate for 1912 on a different basis. A study of the reports of 1899 and 1904 shows that the increase in the value of manufacturing machine » tools, and implements for that period was in approximately the same ratio as the increase in all capital. The estimated value of capital in 1921, including machinery, etc., was obtained by applying the annual rate of increase from 1904 to 1909. It was then assumed that machinery, tools, and implements increased in value at the same rate as the total capital.”

The figures arrived at in the above way and actually given in the census tabulation are the following:

1904 $3,297,754,180 1912 $6,091,451,274
