The building of lighthouses has chiefly developed during the present century, although a few lighthouses were known to the ancients. The full history of lighthouses, if we could trace it, would be very interesting. If you were asked where the first lighthouse was built you would be quite likely to guess right the first time, because you know that the first ships and the first sailors were around the eastern part of the Mediterranean Sea. You would certainly say somewhere along the eastern coast of that sea. Now as a matter of fact there was a lighthouse on the island of Pharos, just in front of the city of Alexandria, which was built over three hundred years before Christ. This was one of the most celebrated towers of antiquity; in fact, it is classed among the Seven Wonders of the World. It is quite likely, however, that this was not the first lighthouse. Probably there were towers on the Dardanelles, the Sea of Marmora, and the Bosphorus which may have preceded the Pharos of Alexandria. The Romans built lighthouses at Ostia, Ravenna, Puteoli, and other ports. All these ancient lighthouses were towers on the top of which wood was burned at night, and the blaze of the burning wood furnished the light which was to guide the mariner. Two or three centuries ago many lighthouses were built along the shores of France and England. The first lighthouse on the coast of our country was Boston Light, at the entrance to Boston harbor, which was erected in the year 1716. Ever since the United States government has been established, much attention has been paid to our system of lighthouses. In 1852 a lighthouse board was established within the department of the United States Treasury. Great skill and engineering ability are needed in the construction of lighthouses. Our country has long Atlantic, Pacific, and lake coasts to be protected, besides numerous rivers extending over thousands of miles. All along these coasts and rivers our government has established and maintains lighthouses. We have nearly a thousand lights on the Atlantic coast, nearly two hundred upon the Pacific, and several hundred along the shores of the Northern Lakes. The United States has also many fog signals and almost innumerable buoys. Great sums of money are necessary to build these lighthouses, many of which are now of iron. Twelve of our most famous lighthouses have cost a total sum of upward of $3,000,000 for their construction. Each year witnesses a steady improvement in the method of construction and of lighting this multitude of lighthouses.
