A very attractive and interesting comparative thematic chart uniquely arranged on concentric circles around a classic compass rose. The rivers are depicted with their relative distance from the sea, including an index of each river’s length in English miles. Associated towns and lakes are noted and respective countries are identified in capital letters keyed with an index at lower left. Two smaller, partial concentric circles located in the upper corners show additional rivers in the same fashion. This is a fine thematic map that utilizes a unique method to graphically compare the rivers of the world. Only the lakes are hand colored with a green wash, the balance of the map being uncolored. Published in London by Baldwin and Cradock.

The margins exhibit some light toning and two very small tears at upper edge. Map image is very good but for a very light area of foxing near title.
