BEST INFO SOURCE : THE USCS 1848 ANNUAL REPORT TO CONGRESS PROBABLY WOULD BE BEST.
DESCRIPTION : THIS SKETCH OF THE CHESAPEAKE BAY AREA WAS ISSUED TO ILLUSTRATE THE REPORT OF THE SUPERINTENDENT OF THE U.S. COAST SURVEY SHOWING THE PROGRESS OF THE SURVEY DURING THE YEAR 1848. IT GIVES THE MAJOR AND SECONDARY TRIANGULATION LINES FOR THE BAY AND ITS RIVERS. AS OF 1848, TRIANGULATION WAS WELL ALONG TO COMPLETION FROM THE NORTH OF THE BAY TO THE MOUTH OF THE POTOMAC RIVER. THE SKETCH ALSO SHOWS THE TIDAL, ASTRONOMICAL AND MAGNETIC STATIONS AND IDENTIFIES THE PLANE TABLES AND THE HYDROGRAPHIC SHEETS (WHICH WERE DONE IN MANUSCRIPT BUT NOT PUBLISHED AND ISSUED TO THE PUBLIC). WRITER HAS NOT SEEN THE 1848 ANNUAL REPORT, WITH ITS EXPLANATORY MATERIAL, SO FURTHER RESEARCH NEEDS TO BE DONE ON THIS SKETCH.

EDITION & STATE INFO : INFORMAL REPORTS WERE MADE ANNUALLY BY THE SUPERINTENDENT OF THE COAST SURVEY FROM 1816 THROUGH 1850. THESE WERE PUBLISHED BY THE TREASURY DEPARTMENT AND WERE SENT TO CONGRESS. BEGINNING WITH 1851, THESE PROGRESS REPORTS BECAME MORE FORMAL. THEY WERE PRODUCED IN MUCH LARGER QUANTITY AND WERE MORE WIDELY DISTRIBUTED TO SCHOOLS AND OTHER INSTITUTIONS AND INDIVIDUALS IN ADDITION TO CONGRESS. THE U.S. COAST SURVEY BECAME THE PUBLISHER BEGINNING IN 1851. THE WIDER DISSEMINATION WAS AN ATTEMPT BY THE AGENCY TO BUILD A WIDER BASE OF SUPPORT FOR THE ACTIVITIES OF THE COAST SURVEY. BEGINNING IN 1844, THESE REPORTS DESCRIBED IN CONSIDERABLE DETAIL THE PROGRESS OF THE SURVEY INCLUDING IN SECTION III, WHICH PRIMARILY CONSISTED OF THE CHESAPEAKE BAY AND THE OCEAN FRONT OF DELAWARE, MARYLAND AND VIRGINIA. ANNUAL PROGRESS SKETCHES WERE APPENDED, SHOWING THE EXTENT OF THE TRIANGULATION, TOPOGRAPHY, HYDROGRAPHY AND OTHER WORK ACCOMPLISHED UP TO THAT TIME.

HFC OWNERSHIP DATA : THE HUNTINGFIELD COLLECTION HAS A GOOD COPY ON LIGHT PAPER WITH SLIGHT BROWNING AT THE FOLDS. IT HAS AN ACQ. # OF J017-DDT AND A MDHR # OF MSA SC1399-464.
