Baltimore, 30th March, 1818. THE FIRST MODERN SCIENTIFIC SURVEY OF THE PATAPSCO RIVER AND CHESAPEAKE BAY Single sheet (88 x 40 4/8 inches, laid down on linen, trimmed with silk). An exceptionally fine, large and beautiful original manuscript map of the Patapsco River from the City of Baltimore to the mouth of the Charles River in Chesapeake Bay, drawn in black and red ink and colour wash, noting all river outlets, points, and depths, with a long explanatory inscription, and inset of "Loading marks..." and "Table of Triangulation". Signed by Sherburne, Brantz and Wirgman. Provenance: Probable gift of Mrs Phillip T. Tyson to the Maryland Academy of Sciences in January of 1878; deposited at the Enoch Pratt Free Library, Baltimore from 1937, with their ink stamp and shelfmarks. A beautiful map of the Patapsco River and part of the Chesapeake Bay, principally to give definitive soundings of the river and the bay, which are meticulously recorded, with a red line indicating the "loading marks and ranges used for ships of heavy draft ...". These soundings were made by Sherburne, a surveyor with and a Lieutenant in the US navy from about 1813-1827. The survey was conducted by Lewis Brantz, a local merchant, who had travelled extensively and published a memoir of his travels in the western states of America: "He devoted himself, for a long time, to surveying the Patapsco river, its branches, and part of the Chesapeake Bay; the engraved map of which is now found, by expert seamen, to be the best that has hitherto been prepared" (Carnegie Library Pittsbugh). He was instrumental in achieving the building of Maryland's first lighthouse project, recommending that lighthouses be place at the mouth of the Patapsco River at Bodkin Point, North Point and Sparrows' Point. He was president of the Philadelphia and Baltimore Railroad, which he helped to complete in January of 1838, after which he died suddenly.
