It was a brown conical tower on a black cylindrical pier located on Crabtree Ledge, about one mile off Crabtree Neck at the north end of Frenchman Bay. Crabtree is named after the American privateer Captain Agreen Crabtree, the first settler of Hancock.

	Frenchman Bay Frenchman Bay is a bay in Hancock County, Maine, named for Samuel de Champlain, the French explorer who visited the area in 1604. Frenchman Bay may have been the location of the Jesuit St. Sauveur mission, established in 1613. In a 1960 book titled, "The Story of Mount Desert Island", Samuel Eliot Morison wrote, "Frenchmans Bay was so called because it became a staging point for French warships preparing to fight the English." The bay is bounded on the east by the Schoodic Peninsula, and on the west by Mount Desert Island; parts of both are in Acadia National Park. It contains numerous islands, the largest of which is Ironbound Island. The highest elevation of the islands in the bay is found on Jordan Island. The largest town on the bay is Bar Harbor, on Mount Desert Island Mount Desert Island (MDI; french: Île des Monts Déserts) in Hancock County, Maine, is the largest island off the coast of Maine. With an area of it is the 52nd-largest island in the United States, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Sparkplug Lighthouse A caisson lighthouse (also referred to as a sparkplug lighthouse, or bug light) is a type of lighthouse whose superstructure rests on a concrete or metal caisson. Caisson lighthouses were developed in the late nineteenth century as a cheaper alternative to screwpile lighthouses. The caisson design was also more efficient as it could better withstand harsh weather, and was not as fragile. Caisson lighthouses usually have living quarters made of cast iron Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impuriti ..., although some brick examples are known. The two American nicknames were later coined because of the structure's shape. Gallery See also References Lighthouses Marine architecture Caissons {{pharology-stub ...

picture info	Lighthouses Completed In 1890 A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
