Says: The NATURE LIBRARY far surpassed my expectation. 

 1 have already made good use of the books in my work as Science 

 Instructor, and I know that I shall derive information from them for 

 many years to come. The color plates are excellent, its arrange- 

 ment scientific nnd yet simple, and its binding substantial. Fifty 

 dollars would not buy my set if I could not get another.

Says: Doubleday, Page & Co. are to be congratulated on the 

 general excellence of the books comprised in their NATURE 

 LIBRARY. It is the most valuable series I know for the use of 

 the Nature lover, whether he is interested professionally or non- 

 professionally in natural history subjects. 



Nature Library" 



OR six years we have been working steadily to build up ^fjC /|2atUtC 

 and have spent many thousand dollars to bring it to its present form of ten 

 beautiful volumes. The set has become a standard work the only one of its 

 kind in the world and the sale has increased very rapidly, more than ten times 

 as many being sold this season as last. There is no household in the land where these 

 books are not needed ; for grown people, for schools , for children, for everyone who 

 wants to know about birds, flowers, butterflies, mushrooms, insects, etc., this set is 

 absolutely indispensable. 



310|)tt IBurrOUffljS in his introduction well expresses the spirit of the books. 

 He writes: " While accurate an.d scientific, I have found them very readable. 

 The treatment is popular without being sensational.'' 



We have had made a book which to some extent expresses the beauty 

 of t!Tf)f /I^fltUrf JKbratp. It contains some of the colored plates, 

 several of the photographic reproductions, shows text pages, binding,
