The Marine Hospital Service has of late years been more serviceable than ever, especially in the prevention of the introduction of cholera and of yellow fever into our country.

The organization is complete and excellent. There is a supervising Surgeon-General, who has great powers and great responsibilities, a medical purveyor, surgeons, passed-assistant surgeons, and assistant surgeons. These treat an immense number of cases, and not a few have lost their lives in combating epidemics. These officers are selected by examination and entirely removed from any politics, and are bound to go wherever they are ordered, and obey regulations.

LIGHT HOUSES.

Another interesting and most exceedingly important institution connected with naval affairs is the United States Light House Establishment. From small beginnings this has grown to be one of the most important administrative branches of our government, and one which, we may say with pride, reflects the greatest honor upon us in the eyes of the world at large; for a reliable and thorough system of the kind is a blessing and a safeguard to mariners and travelers of all nationalities.

The first light house built in the country which is now the United States of America is said to have been that at Little Brewster Island, in Boston Harbor, Massachusetts, about 1715. Then followed others, all supported by the Provinces in which they were placed, of course. There were by the year 1789 twenty-five light houses on the Atlantic coast, ranging from Maine to Georgia. They were supported by a tax upon vessels which used them, and the tax was paid as part of the port dues, according to the lights the vessel must have passed in reaching her destination. In 1789, the National Government took charge of such matters, and the collectors of customs appointed by the President had charge of lights, and collected the dues. The service was often unsatisfactory, and so, in May, 1838, Congress created a Board of naval officers to determine where lights were actually needed, and to settle other points in the same connection. This led to increased usefulness, and at last, in 1852, the Light House Board was created by Act of Congress, which has usefully existed ever since, the result of their work being a light house system equal to any.

The new Board consisted of three officers of the navy, three officers of the engineer corps of the army, and three civilians, one of whom was the Secretary of the Treasury, and the remaining two persons of high scientific attainments. Such a constitution took its members out of the pale of political appointment, and enabled them to lay out plans which they could themselves hope to see carried into effect.

This Board divided the Atlantic and Pacific coasts, the Gulf of Mexico, the Great Lakes, and the great western rivers into districts, to each of which an inspector, who is an officer of the navy, and an engineer, who is an officer of the army, is assigned. These, under direction of the Board, keep up the light houses and lights, and are charged with the discipline of the light keepers. They make constant visits and report upon the condition of lights, and of the behavior of the keepers, so that the system is as nearly perfect as it can be made when we consider the exposed position and solitude of many of the lights. The great subject of light ships, of whistling buoys, of gas-lighted buoys, and other warnings to mariners, belongs to the same subject, but would require a large book to treat them properly. Our people at large do not appreciate the service of our light house establishment, not only on the sea coast, but on the great rivers and lakes, because they do not see it. If they did see it, they would see what it has accomplished, and how commerce would be hampered without it.

It is a magnificent work, and now, in our country, the immense number of lights, beacons, lightships, buoys, and fog-signals are kept up entirely by the general government, without making any charge in the way of light duties against ships of any country.
