 obtained for from twenty-five to forty dollars. 



It is well to buy a standard make of pump,

 to three or four acres in size, and for larger 

 orchards where the trees are not over twelve 

 or fifteen feet in height, this kind of spray rig 

 is the most practicable and advisable, when the 

 expense is taken into consideration. This ap-

The power of a traction sprayer is developed 

 from the wheels. There is much discussion as

 spray can be supplied by this method. By ac-
