 of sap, which used to feed the branch as- 

 cending in that direction. 



One of the bad consequences that usu- 

 ally follow the taking off a branch in a 

 different manner from that just mention- 

 ed, is a proof in support of the present 

 argument. The inequalities or furrows 

 on the trunks of trees, (by the carpen- 

 ters called TROUGHS,) are occasioned by 

 leaving stumps or snags, in that opera- 

 tion. In such a case, if the stump do

 that, ultimately, a furrow is formed, 

 deepest and widest at its base, and de-

 somewhat similar under the branch, and 

 both are undoubtedly occasioned by the
