Originally produced by Edmund Halley (of Halley's Comet fame) in 1700, this map shows magnetic variations of the compass, with a double-line crossing just south of Bermuda indicating the line of no magnetic variation and is corrected to include improvements to Halley's method developed in 1744. Place names are focused on the coasts, with the otherwise blank interiors of the continents supporting decorative cartouches. An image of a pair of diving ducks appears near the southern tip of South America along with a note explaining that "animals of a middle species between a bird and fish" can be seen in the seas in the area. It is also interesting in that the graticule goes through the map rather than drawn on the borders.
The original cartography was based on maps from c.1713. It remained unchanged through it's various printings and states (as late as 1784) giving it a somewhat dated look as compared to other maps published of the area during the same time period.
Although Walter has a notation on the map of c.1745, research definitely marks this as the 4th State with the extension of the fishing banks to Cape Race and the added stippling of the fishing banks. This state was published unchanged in the English Pilot. 4th Book from 1753-1775.
