THE AMERICAN NATURE SERIES 



In the hope of doing something towards furnishing a series where the 

 nature-lover can surely find a readable book of high authority, the pub- 

 lishers of the American Science Series have begun the publication of the 

 American Nature Series. It is the intention that in its own way, the new 

 series shall stand on a par with its famous predecessor. 



The primary object of the new series is to answer the questions which 

 the contemplation of Nature is constantly arousing in the mind of the 

 unscientific intelligent person. But a collateral object will be to give some 

 intelligent notion of the "causes of things." 



While the co-operation of foreign scholars will not be declined, the 

 books will be under the guarantee of American experts, and generally 

 from the American point of view ; and where material crowds space, 

 preference will be given to American facts over others of not more than 

 equal interest. 



The series will be in six divisions :
