THE PROBLEM IN DETAIL. 



EXPLANATION OF DIAGRAMS. 



To illustrate the actual application of the methods of cutting which 

 have been recommended, a series of diagrams has been sketched 

 from nature for t^^pical problems in second-growth woods. The 

 sketches were made in Massachusetts, Connecticut, Rhode Island, and 

 southern New York. Their purpose is to shovv for typical stands of 

 various ages and conditions exactly which trees should be cut. In 

 each case a strip has been taken 15 to 30 feet wide and from 20 to 200 

 feet long. The exact length is stated on each diagram. To give some 

 idea of how the trees are placed with reference to each other, the 

 ground is shown in rough perspective, but the crowns are drawn only 

 in outline, so as to keep them distinct without obscuring their vertical 

 relations. The variation in the shape of crowns, so far as it indicates 

 the relative vigor of the trees, is also represented. The name of the 

 species is printed on each tree, and the condition, whether top-diy, 

 lire scarred, or unsound, is designated by conventional features which 

 explain themselves. The individual trees are referred to in the text 

 by name and number. In each sketch the trees to be cut are marked 

 with a heavv line at the base.
