This evil may be prevented by the sawing

 advanced, by plugging. The decayed base, 

 too, we find in many of our woods, and we 

 find it both in dry and wet land ; this is 

 probably owing to injudicious selection of 

 trees in young plantations, or to full maturity 

 in the case of older timber trees. This 

 deserves, however, a more minute treatment 

 hereafter. 



Then we come to those indications which 

 are not so apparent. Now, the general 

 observer is satisfied if he sees the trees
