A mammoth, detailed and rare 18th-century American chart of Chesapeake Bay. From John and William Norman’s American Pilot, one of the earliest atlases published in the United States.
This impressive chart depicts the complex coast from New Jersey south to just below Cape Henry, Virginia. It provides an immense amount of detail for Delaware Bay and in particular for Chesapeake Bay, including the coastal geography, shoals, many hundreds of depth soundings, and in places information about the composition of the seabed (useful for navigators trying to confirm their location). Numerous place names are given, including both towns and hundreds of plantations along the James, York, Rappahanock and Potomac Rivers. Scattered around the chart are numerous long printed notes giving sailing directions and related information. Near the center is a certification from Osgood Carleton, noted Boston mapmaker and “mathematical practitioner,” to the effect that “I have carefully compared this chart with the Originals and find it to be an accurate copy.”
The chart was compiled from some of the best-available sources, probably by John Norman. The depiction of the Chesapeake Bay region is based very closely on Anthony Smith’s A New and Accurate Chart of the Bay of Chesapeake, (1776). This in turn had been based on Walter Hoxton’s very rare Mapp of the Bay of Chesapeack (1735), with additions from surveys by Smith (a Chesapeake Bay pilot), Fry & Jefferson’s Map of the Most Inhabited Part of Virginia (1775) and perhaps elsewhere. The only changes of substance I have found are along the Potomac River: Norman has added Washington, D.C.; simplified the place name “Belhaven or Alexandria” to “Alexandria;” and changed the label “General Washington’s” to “President Washington’s.” Norman’s treatment of Delaware Bay is derived from that in Joshua Fisher’s 1776 Chart of Delaware Bay and River. I am not however sure where he obtained the many soundings given offshore of Delaware Bay: that area is not shown on the aforementioned sources, and the information does not match that on the Delaware Bay chart in The Atlantic Neptune.
The chart first appeared in a 1794 edition of The American Pilot, a rare atlas of American waters first published in 1791 by John Norman in Boston, and was included in all subsequent editions (the last being 1816). 1794 was the year Norman’s son William took over publication of the Pilot, and his imprint also appears on this chart. Per Wheat & Brun, this is the second of two known states, with the subtitle corrected in the 1803 edition of the Pilot to read “ST MARYS” rather than “ST MAPYS” (For the sake of comparison, the Leventhal Center’s impression of the first state may be viewed here.)
In all, a rare and desirable chart of the mid-Atlantic coast and a substantial rarity of early American mapmaking.

Minor-moderate foxing and soiling, some minor mends and areas of restoration along edges, lined on verso. Withal a very good example of a chart whose size and purpose would have subjected it to much abuse.
