Discoverers and Explorers (Illustrated)

This book has been prepared for the purpose of affording material for such an interrelation. The plan of interrelation is simple. As the study of the world as a whole, in the manner already sketched, progresses, the appropriate chapters are read, discussed, and reproduced, and the routes of the various discoverers and explorers traced. No further word seems to the writer necessary in regard to the interrelation.
