Sketch B Showing the Progress of the Survey in Section No. II From 1844 to 1855
DESCRIPTION
A triangulation chart from Delaware Bay north to New York, Long Island, Long Island Sound, Connecticut, and up to Point Judith. This chart has numerous place names and locations called out and also includes a Sub-Sketch showing the triangulation detail at the Hudson River.
IMPORTANT NOTE:
All of our United States Coast Survey (USCS), United States Coast & Geodetic Survey (USC&GS), and similar maps and charts have been professionally unfolded and flattened using humidity baths, semi-permeable membrane, and drying blotter techniques. Most others you typically see on eBay have not been, and worse, are quickly and crudely unfolded for the low-quality photos you see. Unfolding these maps in that way is damaging and weakens them. Please be aware.
