be bought: (i) A Hardie Eastern Triplex power sprayer with 2oo-gallon 

 tank; a triplex pump with 2j-inch cylinders; a vertical 3 -horsepower 

 Ideal engine; two lines of |-inch hose, each 100 feet long; a 12 -foot tower; 

 two extension poles, one 20 feet and the other 12 feet long. (2) A Friend 

 Hilly-orchard Model power sprayer with 2oo-gallon tank; a large-size 

 California model pump; a 3j-horsepower engine; an 8-foot tower; and 

 other equipment the same as for the first-named machine. Each of these 



FIG. 1 66. Spraying from tower and from ground 



machines was mounted on a truck ready for the field. The price of the 

 Hardie machine is $274 f. o. b. Hudson, Michigan; that of the heavy 

 Friend machine is $300 f. o. b. Gasport, New York. At all times it was 

 possible to maintain 200 pounds pressure with either outfit, and both 

 machines gave satisfactory results. 



Bordeaux nozzles were used for all the work because these are adjust- 

 able. A solid stream could be thrown to the tops of the high trees, or 

 a fine spray could be used for the lower limbs.
