Numerous factors influence the cost of spraying. The variety and 

 size of trees and their distance apart, the character and the contour 

 of the land on which the spraying is done, the convenience of facili- 

 ties, the purpose of the spray, condition and kind of material used, 

 the thoroughness of the work, and whether the trees are dormant, 

 partly or wholly in foliage, all have their bearing on the time re- 

 quired for the spraying operation. The average cost for spraying 

 where all records are considered is $13.15 per acre for material and 

 $9.86 for labor, or a total of $23.01 per acre. , (See Tables XVI 

 and XVII.)
