"Map Showing the Position of Chicago in Connection with the North West & the Principal Lines of Rail Roads, Canals, Navigable Streams and Lakes…",

This very rare, pre-fire map of Chicago shows the extensive railroad network, establishing the city as the transportation hub of the Midwest. The upper peninsula of Michigan is noted as "inexhaustible mines of the finest copper and iron in the world." A key identifies coal formations, lead mines and salt works. At lower right is an inset of Illinois. There appears to be only one record of this map per WorldCat, which is housed in the Library of Congress. Engraved by Edward Mendel.
