Fine example of this extremely scarce separately issued engraved nautical chart on 3 sheets, covering Delaware Harbor and Bay from the mouth of the harbor to Trenton.
While the map appears occasionally on the market bound into an early coast survey volume, the thin paper and browned folds invariably leaves it in problematic condition. The present example is a separately issued example on very heavy paper. Many of the coast survey maps were issued in very limited number on heavy paper for presentation purposes or use at sea. We note 3 examples on the market in the past 30 years, including a copy in Arkway Catalog XXVII, in 1986, priced at $1,500 and noted as being browned and wrinkled.
Relief shown by hachures; depths by soundings. Includes 7 coastal views and descriptive notes on the survey, sailing directions, tides and currents. Oriented with north toward upper left. Prime meridians: Greenwich and New York. In upper margin "Presented under authority of an act of Congress of the United States of June 3d 1844 by direction of the Treasury Department, A.D. Bache Superintendent Coast Survey."
