 a ragged wound nearly always follows. 



"In fall -set trees it is 

 generally inadvisable to 

 prune them before spring 

 (unless the tops are so 

 heavy and the bodies so 

 weak that they are likely

 in the soil to supply the 

 added evaporation which 

 takes place from the 

 wounds. If it seems to
