THE NATURE LIBRARY is the 

 only group of b >oks on natural 

 history that gives scientifically 

 accurate information in simple, narra- 

 tive style, and in a way that makes it 

 equally available for studious reference 

 or casual entertainment. 



It represents the first attempt made 

 to illustrate a work of such magnitude 

 and importance with direct photogra- 

 phic reproductions of living subjects 

 of the animal, bird, fish, insect, and 

 floral worlds in their native conditions. 

 Additional to this photographic literal- 

 ness, the fidelity to nature has been 

 greatly heightened by color plates, 

 which are so perfectly treated that the 

 exact tint or tone of the living original 

 is preserved through all the varieties 

 of color. Thus the identification of 

 any bird, flower, moth, etc., is easy, 

 and its classification becomes a matter 

 of the utmost simplicity, an advantage 

 of inestimable value to the student or 

 general lover of nature hitherto per- 

 plexed and discouraged by old- 

 fashioned so-called "keys." 



This is the first time a systematic 

 effort has been made to bring the read- 

 er into an intimate knowledge, free 

 from fanciful invention, of the lower 

 world. The difficulties of photograph- 

 ing wild animals in their native en- 

 vironment, birds on their nests, and 

 timid creatures in their hidings, are 

 sometimes insuperable; but the success 

 that rewarded the fatigues and hard- 

 ships of tne makers of the Nature 

 Library, and which is . attested 

 throughout the pages of the ten beauti- 

 ful volumes, makes this set of books 

 not only unrivaled, but absolutely 

 unique in the field. 

 Besides the 450 half-tones from

photographs taken especially for this 

 work in all regions of the country, and 

 the 300 extraordinary and remarkably 

 lifelike color plates, there are about 

 1,500 text-cuts, such as are usually re- 

 garded as all-sufficient illustrations of 

 theses on natural history. 



In the actual value of the pictorial 

 matter, the purchaser gets more than 

 the price of the ten volumes: and yet 

 the information, charmingly, familiar- 

 ly presented in the 4,000 pages; is a 

 treasury from which the most careless 

 reader may extract a sort of riches he 

 would not willingly lose again. 



But the Nature Library is not hav- 

 ing careless readers. One point more 

 frequently emphasized than any other 

 by those who write in voluntary ac- 

 knowledgment of their satisfaction 

 with the purchase is the "entertaining" 

 quality of the books. 



Entertaining they most unquestion- 

 ably are — entertaining to old and 

 •young alike; and that was the great 

 object aimed at by the makers of The 

 Nature Library, who believe that 

 the secret of all education is to 

 make instruction entertaining 

 and inspiring. We believe 

 nothing better suited to the 

 double purpose than thest 

 ten handsome and beau- 

 tifully illustratedbooks 

 has been offered to 

 the public in many 

 years. ^^ v/ c °V
