1889 Sea Chart Map of Delaware Bay by George Eldridge, Chart No. 11

Presented is an original Eldridge's Chart No. 11, Delaware Bay and River, from The United States Coast and George Eldridge's Surveys, published in 1889. The sea chart shows the Delaware Bay from its mouth up to just north of Philadelphia.

The sea chart is dense with hydrographical information, including soundings, shoals, lighthouses, buoys, compass roses, and shoals. It also offers sailing directions and notes on tides and currents. Dotted lines on the chart give sailors the distance and sailing directions between ports and numerous buoys or other intersections. Some towns and cities appear inland as block plans, among them Philadelphia, Wilmington, Delaware City, and Greenwich.

The map was published by S. Thaxter & Son, whose stamp appears on the chart, dated 1889. Another vintage stamp, for Charles A. Harriman, a dealer of charts and other nautical goods based in Maine, is located in an unengraved area at top.

Large-scale nautical charts are generally rare on the market today due to the fact that they were used in a damp, rough environment and generally discarded as updated versions became available.
