3. This work, like that relating to light houses, is under the management of a board, consisting of a superintendent, two principal assistants, two naval officers, and four officers of the army. These nine constitute the board. Then there are as many officers of the army and navy employed in the execution of the work as are deemed necessary. And the public vessels, by direction of the President, may be used in order to facilitate the work, for much of it must be done at sea. The survey extends 20 leagues from the shore. The surveyors must make accurate charts of the whole coast, in which are laid down all the islands, shoals, roads or anchorage grounds within twenty leagues of any part of the shore of the United States. The courses or distances between the principal capes or headlands must be laid down, together with the soundings (depths of water) and everything else necessary to make a complete and accurate chart of every part of our coasts.
4. An annual report of this work must be made to Congress in December of each year, accompanied with charts, showing the progress of the work, the number of persons employed, the expenses incurred, the amount of work finished, and what is unfinished. These reports and charts are carefully preserved, and copies of them may be had at Washington for the use of our naval and merchant ships, to which they are of great service, as guides, whenever they are on or near the coast. This work, in its utility, is not confined to ourselves; but the important information obtained by it is of great use to the navigators of all nations who come into our ports or cruise on our coasts. They derive the same benefits from this work that we derive from theirs of the same kind. It is creditable to any nation to do such things as are beneficial to the world, such acts as contribute to the welfare of humanity. Shipwrecks belong to the list of terrible calamities which often befall those “who go down to the sea in ships, that do business in great waters.” Whoever diminishes these is a public benefactor.
CHAPTER XXVIII.
LIGHT HOUSES.
1. These, with Buoys, and Beacons, are a necessary practical supplement to the labors of the Coast Survey. Buoys and Beacons indicate the shoals, or dangerous rocks and reefs beneath the surface of the water, in the daytime; while light houses indicate the same, and show the mariner the bearings of the land, in the night; and, by studying, in connection with these, the charts of the coast supplied by the Coast Survey, he may make his way as securely in the night or day through the concealed dangers of the treacherous waters as a landsman along a beaten highway. They are way-marks along the sea coast, at the entrance of harbors, and on lakes and rivers. They speak a language very well understood by the seaman; and are invaluable for the protection of his vessel from the dangers of the Deep.
2. Keepers are appointed by the government to keep them in repair, and to see that they are properly lighted every night. We have no means of knowing the number of these useful establishments, but there must be several hundred of them; for we have more sea coast than any other nation upon the globe, with a still greater length of lake and river shore. They are located at prominent points, and at dangerous places, all along the extensive lines of coast and shores.
3. To the end that light houses should be constructed and kept in repair, and that competent men might have the whole matter in charge, a law of 1852 authorized the President to appoint two officers of the navy of high rank, one officer of the corps of engineers of the army, one officer of the topographical engineers, and two civilians of high scientific attainments, to form a light house board for the United States. This board is attached to the Treasury Department, and the Secretary of the Treasury superintends its operations. The board has in charge the building, illumination, and inspection of light houses, light vessels, buoys, beacons, sea marks, and their appendages.
4. The Secretary of the Treasury is president of the board, and may convene them whenever he deems it necessary.
The law makes it the duty of the board to divide the whole of the sea, gulf, and lake coasts, into light house districts; not exceeding 12 in number. An officer of the army or navy is assigned to each district, as a light house inspector.
