PREFACE.

This little book belongs to the Hand-Book series, which has been received with favor during the last few years. The success which attended the publication of these unpretentious volumes and the large number of inquiries from owners of water and steam power and other capitalists, as well as from agents of hydraulic and electric power companies, engineers of power transmission stations, motor inspectors and other persons interested in power transmission, induced the author to prepare this new handbook. As usual the author has endeavored to avoid as much as possible the use of scientific terms and has employed only simple algebraic formulæ. For those who wish to study the subject of electric power transmission beyond the compass of this hand-book the following named works are recommended: "Electric Transmission of Energy," by Gisbert Kapp, C. E; "Kritische Vergleichung der Kraftuebertragung mit den Gebrauchlichsten Mechanischen Uebertragungs Systemen," by A. Beringer; "Dynamo Electric Machinery," Ly Prof. S. P. Thompson; Electric Motors," by F. J. Sprague (late Ensign U. S. N.), a paper read before U. S. Naval Institute, Annapolis, May 16, 1887; "The Transmission of Power by Electricity," by F. J. Sprague, a lecture delivered before the Franklin Institute, Nov. 12, 1888; "Some Applications of Electric Transmission," by F. J. Sprague, a lecture delivered before the students of Sibley College and published in the Scientific American, July 20 and 27 and Aug. 3. 1889; the papers of George W. Mansfield, Richard P. Rothwell, Francis A. Pocock, H. C. Spaulding

and others, read before the American Institute of Mining
Engineers, and the paper of H. Ward Leonard, read be-
fore the Association of Mining Engineers of the Province
of Quebec, April 29, 1891. This work was almost ready
for the press, when Kapp's Cantor Lectures and CE L.
Brown's paper before the Electrical Society of Frankfort-
on the-Main were received.

Reference has been made, as far as time and space would
permit, to ideas found in these works.

Chicago, June, 1891.
