Special Practices 37 



ing of standard full-size trees is the general practice; the 

 growing of dwarfs is the special practice and must justify 

 itself. Leaving the roots on trees when they are trans- 

 planted is general practice; cutting them off is special 

 practice, and it may work. , , 



The general practice is always the norm. It is not to be 

 discarded except for very good reasons. The burden of 

 proof is on the special practitioner. The grower may save 

 himself much confusion, as also considerable bad and 

 injudicious labor, if he keeps these distinctions in mind. 

 He should read every article and analyze every lecture 

 with this conscious discrimination. Much needless com- 

 bat is waged over special practices.
