Efficiency of operation 



Spraying on the 40 farms was not an identical task. (Figure 13.) 

 The number of sprays varied from 4 to 1 1 and the gallons applied ranged 

 from 10 to 50 gallons per mature tree equivalent. The equipment ranged 

 from small horse-drawn 100-gallon tanks to large 350-gallon, high- 

 pressure, tractor-drawn outfits. In addition, the hill orchards some dis- 

 tance from the buildings, and without a near-by water supply, repre- 

 sent special difficulties as compared to the orchard on level land, near 

 the buildings.
