Setting the Plants. In preparation for planting trees 

 and shrubs the holes should be dug at least four feet 

 in diameter and two feet deep. If the soil is hard 

 and poor, it should be replaced by good earth, and 

 the tree should be mulched with coarse litter, after 

 the earth has been firmed well about the roots of tho 

 tree. Do not use water in planting unless the soil is 

 very dry. The cut ends of all roots should be smooth- 

 ly re-cut before planting. Probably one-half of the 

 top should be pruned from the tree or shrub in order 

 to give balance to the roots.
