THE BOTANICAL OUTFIT 31 



quarto, $13.50, Charles Scribner's Sons, New 

 York. This is the only work which attempts 

 to give pictures of all the plants of any part 

 of North America. It covers a territory ex- 

 tending from the southern boundary of Vir- 

 ginia to the Arctic regions and west to the 

 100th meridian and has line drawings, of vary- 

 ing degrees of excellence but usually helpful, 

 of no less than 4,666 species. 



Gray's New Manual of Botany, $2.50, Amer- 

 ican Book Co., New York (edition on thin 

 paper, bound in limp leather, convenient for 

 carrying into the field, $3.00) . This, the latest 

 of the well-known series of Gray's Manuals, 

 covers about the same territory as the Illus- 

 trated Flora, except that it takes the 48th par- 

 allel as its northern boundary. It contains 

 more than nine hundred small but admirable 

 line drawings of flowers or important details 

 in the more difficult groups of plants. 



These are technical works. If you carry 

 your botanical studies very far, you will want 

 one or both of them ; but for the beginner some 

 simpler and less comprehensive book is easier 

 to use. Such are :
