Book excerpt: Excerpt from Memoir Upon the Light-House Illumination of the Coasts of France The entrances to ports and the mouths of navigable streams were for a long time regarded as the only places at which it was needful to establish lights for the benefit of the mariner, and the chief object and effort then was to give as great a range as possible to the lights thus placed to mark those points. It is now, and has been for some time, quite different; the requirements of navigation having become so much greater, it follows, as a necessary consequence, that they should be more amply and fully met, and, in being more fully developed, the illumination of maritime coasts rests upon very different laws from what it formerly did, as it is now recognized that the greater number of the localities hitherto considered of primary importance need only be provided with lights of a secondary character, while the primary lights are assigned to positions where they will render better service to the mariner.
