The first navigational lights in the New World were probably lanterns hung at harbor en-trances. The first lighthouse was put up by the Massachusetts bay Colony in 1716 on Little brew-ster Island at the entrance to boston Harbor. Paid for and maintained by "light dues" levied （征收） on ships， the original beacon was blown up in 1776. Until then there were only adozen or sotrue lighthouses in the colonies. Little over acentury later， there were 700 lighthouses.

The first eight lighthouses erected on the West Coast in the 1850s featured the same basicNew England design:aCape Cod dwelling with the tower rising from the center or standing closeby. In New England and elsewhere， though， lighthouses reflected avariety of architectural styles.

Since most stations in the Northeast were set up on rocky eminences （高处）， enormous towerswere not the rule. Some were made of stone and brick， others of wood or metal. Some stood onpilings or stilts; some were fastened to rock with iron rods. Farther south， from Maryland throughthe FloridA．Keys， the coast was low and sandy. It was often necessary to build tall towers there——massive structures like the majesticlighthouse in Cape Hatteras， North Carolina，which was lit in1870. 190 feet high， it is the tallest brick lighthouse in the country.

Not withstanding differences in construction appearance， most lighthouses in Americasharedseveral features : alight， living quarters， and sometimes abell （or， later， afoghorn）. They alsohad something else in common: akeeper and usually the keeper"s family. The keeper"s essentialtask was trimming the lantern wick （灯芯） in order to maintain asteady， bright flame. The earli-est keepers came from every walk of life， they were seamen， farmers， mechanics， rough millhands and appointments were often handed out by local customs commissioners as political plums.

After the administration of lighthouse was taken over in 1852 by the United States Lighthouseboard， and agency of the Treasury Department， the keeper corps gradually became highly profes-sional.
