BOTANICAL BOOKS AND THEIR USE 137 



describing every species of tree in North America. 

 Of a similar character is Eaton's " Ferns of North 

 America," which describes, though on a less elabo- 

 rate scale, all of our ferns. Of books designed as 

 guides to the study of particular groups, there are a 

 few of real authority. Underwood's " Our Native 

 Ferns and their Allies" is one of these, and of course 

 there are many popular works of this character, 

 whose consideration hardly belongs in the present 

 work. If the teacher is interested in other groups, 

 or wishes other information about botanical books, 

 he should consult the Professor of Botany in the 

 nearest large university.
