A highly detailed chart showing New York Harbor and Bay, a fine example of the output of the U.S. Coast Survey. This chart shows evidence of heavy use, perhaps being used by a ship based in New York City. Soundings and other navigational details are precisely depicted throughout the map. Also included are sailing directions and tables on tides and currents. Precise and minute interior information is given for Manhattan, Brooklyn, and Staten Island.
