The very important and interesting information in regard to the present condition of European seacoast illumination, and its cognate aids to com- merce, which is found in the following pages, was collected by Major Elliot, of the United States Engineers, in 1873. and appearing soon afterwards in the form of a report to the Light- house Board, it attracted much attention and commendation. It will be observed that Major Elliot had extra- ordinary and excellent facilities, and that he made the most of them in obtaining a knowledge of the immense improvements which, in later years, have been made in one of the most important of Govermental services. His report, which may be considered to be a complete exhibit of the state of the lighthouse service at the present time, has not been accessible to the public, and in order to satisfy the demand both in this country and in Europe, from en- gineers, scientists, persons interested in commerce, and general readers, the Publisher issues the pre- sent edition. Kew Yoek, June, 1875. EXTRACT FROM THE REPORT OF THE LIGHT-HOUSE BOARD TO THE SECRETARY OF THE TREASURY FOR THE FISCAL YEAR ENDING 30in JUNE, 1H73. The Ligbt-House Board, during the past year, desirous of acquainting itself minutely with any improvements which of late years may have been introduced into the light-house service in Europe, obtained the sanction of the honorable the Secretary of the Treasury to commission Major Elliot, of the Corps of Engineers of the Army, and engineer- secretary of the Board, to visit Europe and report upon everything which he might observe relative to light-house a^jparatus and the man- agement of light-house systems.
