 mot system might be studied. The trees were 

 commercial northern -grown, and were set in a 

 moist and well -tilled sandy loam. They were 

 set on the 4th of May, which was as early as

 pendicularly to the plane or surface of the cut. This final pruning should 

 be done shortly before planting, so as to present a fresh surface for the 

 callus to form on. If trees are to be kept some time, or shipped by a 

 nurseryman, about two inches of root should be left, the planter to cut 

 back as directed when the tree is set. About a foot of top should be left.

 may be left without diminishing the growth much." Stringfellow in
