RELIEF MAP OF THE TERRESTRIAL GLOBE. 



Illustrating the relations of the mountains to the sea, which has uplifted great 

 walls along the borders of the Continents, by the expulsion of lava from beneath the 

 ocean and its injection under the land. This impressive view of the Earth shows 

 at a glance that the mountains have been formed by the Sea. From Frye's Complete 

 Geography, by permission of Ginn & Co., Publishers.
