Cape Cod Lighthouse

From my house in Dennis on Cape Cod, when the weather is clear, I can see the flash of the Cape Cod Lighthouse at Highland (often referred to as the Highand Light) on the back shore of the Cape, 19 miles across the bay. It's a comforting sight for any sailor who has wandered the world's oceans. In fact those who go "in peril on the seas" have owed their lives to the faithful keepers of lighthouses.
