This handsome map of North America prominently features the mountain ranges with the Stony Mountains in Canada and the Topian Mountains in the southwestern U. S. and Mexico. Several Indian tribes are located, and there are notes concerning the recent discoveries by Mackenzie and Hearne in the Arctic. Above the Missouri River is a dotted line representing the river "according to former conjectures." Engraved by W. Miltea and published by J. McGowan.
