Sargent's Manual.^ — No other person so well equipped for the 

 description of North American trees as Professor Sargent could have 

 been found, nor an illustrator so expert and practiced as Mr. Faxon; 

 hence it results that no manual of our trees so good as the present 

 could have been expected from any other source. To the makeup 

 of the book the Riverside Press have brought their usual skill. The 

 total result, therefore, is a well devised, well written, well illustrated, 

 and well made book, condensing into convenient size what is neces- 

 sary for the study of our trees,. and yet not skimping the descriptions. 

 As was to be expected, the sequence (after Engler and Prantl) and 

 nomenclature (after Sargent's Silva) are rather radically modern, 

 while the treatment of species is rather conservative except in the 

 daily amplifying genus Cratfegus, to which further species are here 

 added. 



A synopsis of families with a key based on their leaves renders the 

 first placing of a given form easy, while genera and species are differ- 

 entiated in the same manner. 



If any fault is to be found with the book it will probably be with the 

 absence of synonymy, especially that referring to the new names intro- 

 duced, except for references to differing names employed in the author's 

 Silva.
