This is A. J. Johnson’s fine 1862 map of the world on Mercator’s Projection.  Depicts the entire world centered on North and South America.  Offers a fascinating snapshot of the world during a period of rapid globalization and discovery.  Africa is largely “unexplored” and both Lake Victoria and Lake Tanganyika have yet to appear.  The Antarctic continent is shown only sketchily, representing the relatively primitive state of Antarctic exploration in 1862.  Shows the path of important explorers including Cook and Wilkes.  Also notes several ship routes between America and Europe as well as the path of the Atlantic Telegraph Cable.  Features the strapwork style border common to Johnson’s atlas work from 1860 to 1863. Prepared by A. J. Johnson and Ward for publication as plates no. 6 and 7 in the 1862 edition of the  New Illustrated Atlas… .
