COMSTOCK] LEAF-PORTFOLIO AN AID IN TREE-STUDY 



199 



Another and more elaborate portfolio is made by water color 

 drawings of the leaves and fruits. This is a rather extensive 

 imdertaking and usually results in an unfinished portfolio. A less 

 difficult method and more easily accomplished is to simply trace 

 or draw the leaves with a pencil or pen ; and this is quite as valua- 

 ble pedagogically as the more elaborate drawings. 



Still another method is that of making blue prints of leaves ; this 

 is a favorite with young photographers. The blue print paper is 

 cheap, the prints are easily made and are clear and satisfactory. 

 These prints should be carefully trimmed and mounted on uniform 

 sheets of paper.
