Certain kinds of fruits — apples, pears, &c. — may \^ checked and

 able distance from the base of the trunk, and then working beneath the 

 same as if lifting the tree with a massive ball of earth. When performing 

 this operation, care should be exercised that the roots are cleanly severed, 

 and that no top r;:Gts are left uncut. The distance of opening out the

 tree with surface spreading roots requires to be opened out a greater 

 distance away than one having its r<x)ts growing downwariis.
