Their graduates elevate the standard of intelligence in the community, especially when they engage in the work of in

struction.

Both of these institutions are supported at the expense of the government. The tuition and board of cadets in one, and of the midshipmen in the other, costs them nothing.

CHAPTER XXVI.

THE NAVAL OBSERVATORY.

1. An observatory is a building erected for astronomical purposes, and supplied with the necessary apparatus for studying the heavens. A thorough knowledge of certain portions of astronomy is indispensable to the commander of a vessel, since it is by means of this alone that he can ascertain his exact position on the open ocean out of sight of land. Nautical Science and Astronomy have advanced hand in hand; and to perfect the former as much as possible the United States Government established the Naval Observatory. This institution is located in Washington, and was originated by act of Congress in 1842, and put in operation in 1844.

2. This institution owes more to that enlightened and truly patriotic President, John Q. Adams, than to any other man. He recommended it as far back as 1823, and again in his first message to Congress. But political opposition to the man prevented his recommendations from being acted upon till nearly 20 years after they were made. This opposition was finally overcome, and we, and posterity after us, will reap the fruits of Mr. Adams' suggestions and labors.

3. The observatory was built and furnished with various astronomical and philosophical instruments, and a corps of professors were appointed to watch the movements of the heavenly bodies, and to make such observations and experi

ments as would enable them to determine many unsettled questions which relate to the science of navigation; and incidentally to another great government work, having especial reference to the same subject; that is, the coast survey.

The coast survey has already been of great service to the interests of navigation-whether national or commercial vessels are regarded-and, when finished, much greater benefits are to be expected. When a sufficient number of observations and experiments shall have been made at the naval observatory, and published to the world, much valuable information will be added to what is already known. And indeed it would be disreptutable to a nation having so large a navy and such a vast number of merchant ships upon the ocean, to do nothing for or add nothing to the science of navigation. It would be an unwise policy if economy only were studied, and we would justly deserve the reproach of being penurious, short-sighted, and miserably wanting in disposition to promote the general good of the world.

4. The professors are assiduous in their labors, and publish the results of their observations and the facts they have determined. These are not only of use to our own seamen, but to those of all nations who are doing business on the great deep. Here the charts made by the coast survey are deposited, and from hence all our national vessels are furnished with them, and with all the nautical instruments they require.

The charts, instruments and books relating to astronomy and navigation, found here, make it the headquarters and depot of nautical science in the United States.

CHAPTER XXVII.

THE COAST SURVEY.

1. While the Naval Observatory is a government institution for studying the heavens in the interest of the Navy; the

the depths of the waters.

Coast Survey is an organization employed in a thorough and scientific study of the shores of our country for a sufficient distance out from the land to ascertain all the features concealed by the water that may have a bearing on the safety of our navy and commerce. One examines the heavens, the other They are both of great importance. 2. This government undertaking has not been as vigorously prosecuted as some other enterprises conducted by it. As early as 1807, Congress passed an act authorizing the President to have this work done. Much of it has been done, yet it is not finished at this day. Our acquisition of Florida, Texas, and California has greatly extended our sea coast since the work was commenced, and its accomplishment has cost more time and labor than was anticipated at the beginning, yet we think it ought to have been completed in much less than 60 years.

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 practi cal 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.

They have the control of everything relating to light houses, light ships, buoys, beacons, or other means of directing vessels in and out of port, or of guiding them while sailing along the coast in the night.

5. As foreign vessels receive the same benefits from our light houses as our own, there is nothing unfair or illiberal in requiring them to contribute something towards the expense of maintaining them. For this purpose Congress has imposed a tax, or laid a duty of 50 cents per ton on all foreign vessels entering any ports of the United States. This is called "LIGHT
