CHAPTER XIV 

 NOTES ON THE VARIOUS SPECIES 



IN the preceding chapters trees have mainly 

 been considered in general, the different spe- 

 cies having been rarely mentioned. The various 

 kinds of trees, however, are subject to different 

 diseases and to different kinds of injury. These 

 special needs demand special treatments. The 

 present chapter consists of an alphabetical list of 

 the commonest trees, with notes on the special 

 characteristics, important in tree repair, which dis- 

 tinguish each kind. These notes are intended 

 simply to indicate additions to or exceptions from 

 the general rules previously laid down, and are in 

 no sense complete guides to the treatment of the 

 varieties concerned. If in a few cases these limits 

 seem to have been exceeded, it is because the 

 temptation was great to make this chapter a catch- 

 all for facts and opinions which did not seem to 

 fit in anywhere else.
