We learn from Samuel Flanders, Esq., that a light house is to be erected at Gay Head the coming fall. It is to be located about five or six rods back of the present one. The light, at an altitude of 60 feet, will be seen by mariners over Noman’s Land, which will be of great service. A new dwelling house is also to be erected. An appropriation of $13,000 was made at the last session of Congress to cover the expense of constructing these buildings.
