Casco Bay, Maine

DESCRIPTION: SOLD.

Original old, rolled antique sea chart of the inside passages for Casco, Bay Maine that has seen usage afloat based on the light pencil course plot lines. This large old navigation chart on heavy paper, first published in 1870 by the U.S. Coast and Geodetic Survey, carries the patina of age while retaining almost all its original beauty. Numerous lights and aids to navigation are captured along with a host of nautical hazards: Temple's Ledge, Ram Island Ledge, Halibut Rocks, Dick's Shoal, Sisters Ground, and many more. Lots of opportunity to run aground… or worse.

Coverage includes the geographical features of Cape Elizabeth, Peak's Island, Cushing Island, Luckse's Sound, Presumscott River, Fort Gorges, Fort Preble, Fort Scammel, Portland Head Light, Whaleboat Island, Great Chebeag Island, Quohog Bay, Crotch Island, Cape Small, Maquoit Bay, Bald Head, Sebascodegan Island, Harpswell Neck, New Meadows River. Poulation centers include: Portland, Maine, Falmouth Corner, Yarmouth, Freeport Landing, and South Freeport. Chart number 315.

This chart (Electroype copy No. 2) was printed on or after 1901 from an electrotype plate of the original hand-engraved copper plate, a process the U.S. Coast Survey adopted around 1850. As a soft medium, copper plates could only withstand print runs of perhaps 200 copies before the plates wore down. To enable larger print runs, a mold of the original plate was created in wax or another soft medium. Then, using an electro-chemical processs ( electrotyping ), the mold was coated with a metal layer, typically copper. Printers were then able to produce output from the new electrotype copper copy, while preserving the original.
