Illustrated Flora of the Northern U. S. and Canada, Britton and 

 Brown, three volumes, XXVIII plus 2051 pages, second edition, 

 Chas. Scribner's Lons. Price $11.00. 



All students of nature-study are familiar with this book which 

 has long been a standard for plant descriptions. This second edi- 

 tion is in many particulars an improvemnent over the first edition. 

 The plants included are the Pteridophytes and the Spermatoph^^tes . 

 The thing which makes these volumes particularly valuable to the 

 nature student is the fact that every plant is illustrated with line 

 drawings which 1 ke it fairly easy for one who is not familiar with 

 the technology of botany to follow understandingly the descrip- 

 tions. The books are provided with keys by which one may 

 determine any plant. While at the outset it seems a little difficult 

 to use the books unless you are a botanist, you shortly come to find 

 them invaluable, and because of their accuracy and the explicit 

 distinctions, they soon supersede in use the popular books on plant 

 detenninations, such as, How to Know the Wild Flowers; How to 

 Know the Ferns, etc., which are written distinctly to aid the 

 uninitiated. Certainly, no school library is complete without these 

 volumes, and any individual who is interested in the higher plants 

 will possess them with delight, even if he must forego half a dozen 

 other nature books to obtain them. One is tempted to deal in 

 superlatives when you turn the pages of these volumes, — the cuts, 

 typography and subject matter are all so superior. 



There is far less difference in the scientific names used for the 

 plants now between this second edition and the recent edition of 

 Gray's Manual, than there was between the first edition and the
