This is an uncommon 1849 U.S. Coast Survey nautical chart or maritime map of the Buttermilk Channel in New York Harbor. Separating Governor's Island from Brooklyn, the Buttermilk Channel is approximately a mile long tidal strait in the upper New York Bay in New York City. This chart covers from Governors Island to Red Hook in Brooklyn, and includes the Atlantic Basin (Atlantic Dock and warehouses), built just two years before this chart was published.

There are many accounts on how the channel got its name. The channel, which is now flows deep, was once shallow and choppy and its waters would foam like buttermilk. Some suggest that dairy farmers delivering milk to Manhattan by boat found their milk churned into butter by the time they got across the turbulent waters. Others believe that before cargo ships, cows were driven across the channel at low tide to graze on Governors Island. Walt Whitman, in his newspaper article about Brooklyn history writes, 'as late as the Revolutionary War (when) cattle were driven across from Brooklyn, over what is now Buttermilk Channel, to Governors Island.'

The chart contains a wealth of practical information for the mariner from oceanic depths, to notes on tides and sailing instructions, positions of buoys, etc. This chart was published by the Hydrographic party of the Coast Survey under the command of Lieutenant D. D. Porter of the U.S. Navy and was compiled under the direction of A. D. Bache, Superintendent of the Survey of the Coast of the United States and one of the most influential American cartographers of the 19th century, and issued in the 1849 edition of the Superintendent's Report.


The Office of the Coast Survey (1807 - present) founded in 1807 by President Thomas Jefferson and Secretary of Commerce Albert Gallatin, is the oldest scientific organization in the U.S. Federal Government. Jefferson created the "Survey of the Coast," as it was then called, in response to a need for accurate navigational charts of the new nation's coasts and harbors. The spirit of the Coast Survey was defined by its first two superintendents. The first superintendent of the Coast Survey was Swiss immigrant and West Point mathematics professor Ferdinand Hassler. Under the direction of Hassler, from 1816 to 1843, the ideological and scientific foundations for the Coast Survey were established. These included using the most advanced techniques and most sophisticated equipment as well as an unstinting attention to detail. Hassler devised a labor intensive triangulation system whereby the entire coast was divided into a series of enormous triangles. These were in turn subdivided into smaller triangulation units that were then individually surveyed. Employing this exacting technique on such a massive scale had never before been attempted. Consequently, Hassler and the Coast Survey under him developed a reputation for uncompromising dedication to the principles of accuracy and excellence. Unfortunately, despite being a masterful surveyor, Hassler was abrasive and politically unpopular, twice losing congressional funding for the Coast Survey. Nonetheless, Hassler led the Coast Survey until his death in 1843, at which time Alexander Dallas Bache, a great-grandson of Benjamin Franklin, took the helm. Bache was fully dedicated to the principles established by Hassler, but proved more politically astute and successfully lobbied Congress to liberally fund the endeavor. Under the leadership of A. D. Bache, the Coast Survey completed its most important work. Moreover, during his long tenure with the Coast Survey, from 1843 to 1865, Bache was a steadfast advocate of American science and navigation and in fact founded the American Academy of Sciences. Bache was succeeded by Benjamin Pierce who ran the Survey from 1867 to 1874. Pierce was in turn succeeded by Carlile Pollock Patterson who was Superintendent from 1874 to 1881. In 1878, under Patterson's superintendence, the U.S. Coast Survey was reorganized as the U.S. Coast and Geodetic Survey (C & GS) to accommodate topographic as well as nautical surveys. Today the Coast Survey is part of the National Oceanic and Atmospheric Administration or NOAA as the National Geodetic Survey. More by this mapmaker...
