 with a guide to the study of trees and shrubs from the 

 point of view of the outdoor naturalist. At the same 

 time I hope to interest them in certain methods of 

 laboratory work, which help us to amplify the results of 

 field-studies by the examination of the objects observed 

 in their native habitats, somewhat more closely under 

 the lens or microscope. 



Somewhat gloomy views have occasionally been ex- 

 pressed by botanists who deplore the neglect of natural 

 history studies in the open, the now common use of the 

 microscope and of laboratory methods having, in their 

 opinion, exercised a powerful fascination on the study 

 of plants detrimental to outdoor work. Considerable 

 experience has convinced me that the neglect of the
