be drawn by means of a hose. They have a cylinder that is lined with 

 porcelain, which gives it a wearing power and enables it to withstand the 

 action of the fungicides. The piston has an adjustable and very durable 

 rubber packing. The water is forced into the large air chamber and is 

 forced out in a continuous stream by the compressed air. This air 

 chamber is of riveted steel and is galvanized upon the inside. In the 

 various sizes of pump, the air chamber varies in size from twenty to fifty 

 inches in height and from two and one half to eight inches in diameter, 

 The size known as No. 1^ is suited to orchards of medium size and sells 

 for about twenty dollars, including hose and nozzles. 



The Field Force Pump Company of Lockport, N. Y,, were among the 

 first to place spraying pumps upon the market. Their 'Standard' spraying 

 outfit (pump, hose, and nozzle) costs with iron cylinder, plunger, etc., $8, 

 and if brass $10. Their * Perfection ' outfit is more powerful and the cost 

 is $9.50 and $12 respectively. It has a long discharge hose and also a 

 return hose for keeping the spraying materials in suspension. These 

 pumps have their cylinders above the barrel and on this account are less 

 desirable than the Empire Spraying Pumps (Fig. 52) made by the same 

 firm. 



The single Empire with suction pipe, return pipe (agitator), 10 ft. of 



discharge pipe, graduating spray 

 nozzle, and with iron cylinder, 

 plunger, and rod costs $8, or $10 with 

 brass cylinder, plunger rod, and valve- 

 seat. The double Empire (Fig. 52) 

 is heavier, with a larger air chamber, 

 etc., and has two discharge pipes 

 and Vermorel nozzles. The price of 

 this pump is $10 and $12.50 respect- 

 ively for iron and brass cylinders, 

 etc. As will be seen from the illus- 

 tration, these pumps have their air 

 chambers within the barrels, thus 

 doing away with the objection urged 

 against the * Standard ' and ' Per- 

 fection' outfits. They also have 

 quite a long handle and are sup- 

 plied with brass strainers over the 

 suction pipes. The Field pumps 

 use leather valves and have stuffing- 

 boxes. 



The Gould Manufacturing Corn- 

 Fig. 52.-Empire Spray Pamp. pany of Seneca Falls, N. Y., are also 

 well and favorably known. They make the * Standard ' Double Acting 

 spray pump with brass-cased plunger and brass-lined cylinder which they 

 furnish as shown in the cut (Fig. 53) with suction pipe and two discharge 

 pipes with nozzles, for $16.50, or with one discharge hose and nozzle for 

 $18.50. This is a very powerful pump, and as it is arranged to be fitted to 

 the side of a barrel there is less necessity for having the cylinder inside. 

 This pump is also made without the air chamber shown in the illustration, 

 for one dollar less than the above prices. It, however, has a hollow 

 plunger which to a certain extent serves as an air chamber. In a general
