296 THE PI.ANT WORLD 



growing within the area under description. Perhaps the most marked 

 and valuable feature of the book are the numerous high-grade illustrations 

 with which its pages are profusely embellished. These, to the number of 

 more than two hundred, are all from original drawings and photographs 

 by the author, and consist of full-page plates showing the species as they 

 appear in their native haunts, of individual plants, and what is of especial 

 value, enlarged photographs of the fructification. The student should 

 have little difiiculty in identifying any species of fern found in the north- 

 eastern States. The closing chapter is devoted to fern photography, in 

 which Dr. Waters tells how it is possible to attain the results with the 

 camera that his illustrations show to be possible. In the matter of book- 

 making only praise is due the publisher, for the typography and printing 

 are superb. If we were to offer any criticism it would be that the ex- 

 ternal appearance of the book does not compare with the interior. 

 Altogether we do not hesitate to pronounce it the ideal fern -book.
