SIR: In compliance with your instructions, I have the honor to submit tables giving in condensed form the statistics of steam- and waterpower used in manufactures, as returned at the census of 1880. These statistics have been compiled under the direction of Professor W. P. Trowbridge, special agent in charge of the statistics of power and machinery used in manufactures, from the returns made upon the schedules used in collecting statistics of manufactures, and include the power used in all industries embraced in the manufacturing statistics, with the following exceptions: Coke, Dyeing and finishing textiles, Glass, Liquors, distilled; Liquors, malt; Mixed textiles; Shipbuilding. The classification by industries is the same as that adopted by the division of manufactures. These tables show: (1) The number of establishments which used either steam- or water-power, or both, during the whole or a part of the census year from June 1, 1879, to May 31, 1880. The number of establishments here reported is generally less than reported as engaged in manufacture for any district or industry, the difference being due to such establishments as do not use either steam- or water-power, or to such as were not in operation during any part of the census year. Thus, in the state of Massachusetts there are reported 350 flouring- and grist-mills, but only 344 of these are returned as using either steam- or water-power, the remaining 6 being driven by wind; (2) the number of water-wheels used; (3) the total power of these wheels; (4) the number of steam-boilers, not including such boilers as are used for generating steam exclusively for heating purposes; (5) the total number of steam-engines used; (6) the total power of these steam-engines; (7) the total power of all the steam-engines and water-wheels reported as used in manufacture during the census year. In Table LV are presented the statistics of power used in manufactures, first, by totals for states and territories, and second, by totals for some of the leading industries. In many cases the same steam-engine or waterwheel was reported as being used in two or more industries. Where no satisfactory division of power could be made, it was included in each industry and a deduction made from the total of all industries for such duplication, as is shown in the table. Table LVI gives the statistics by state totals of the following selected industries, viz: Carpets, cotton goods, felt goods, flouring- and grist-mill products, hosiery and knit goods, iron and steel, lumber (sawed), paper, salt, silk and silk goods, woolen goods, wool hats, worsted goods, the statistics for all other industries being grouped. |
