THEORY OF TRANSPLANTING. OUTLINE OF 

 THE PHYSIOLOGY OF TREES AS REGARDS 

 TRANSPLANTING, PRUNING, &C. 



The supply must be equal to the de- 

 mand; if not, scarcity will ensue. He 

 who expects that a diminished root will 

 support an undiminished head will be 

 disappointed. This is the fundamental 

 principle of transplanting. And in trans-

With the exception stated below, trees 

 imbibe from every part of them which is
