of the tank. H. W. Henry of Laporte, Incl., makes the Utica high- 

 pressure sprayer. This consists of two cyHnders in connection with 

 an air pump attached on the outside. 



The Wallace Machinery Co., of Champaign, 111., makes a com- 

 pressed-air power-sprayer for use in connection with a common 

 wagon tank. The machine consists of a pump and large air 

 tank mounted on an oak frame. The pump is geared to a sprocket 

 wheel on a wheel of the wagon. Air is pumped into the tank to forty 

 or fifty pounds pressure, after which the liquid is pumped in and 

 additional pressure thus secured, the pressure being thus brought 

 up to TOO to 125 pounds. Pressure is also obtained in driving to the 

 orchard, and is maintained by driving from one row to the next, or 

 if the trees are large, by driving to alternate rows. The pump is of 

 brass and adapted for pumping either air or liquid. Power is thrown 

 on or ofif by a lever clutch. The outfit weighs only 275 pounds. 



The Pierce-Loop Sprayer Co. of Northeast, Pa., has recently 

 placed on the market a compressed-air rig (Fig. 45) that has been in 

 use for several years. It consists of a boiler, engine and air-com- 

 pressor centrally located, and two or three carts each carrying two 

 fifty-gallon galvanized iron tanks, one of which is filled with the 

 spray mixture, the other with compressed air, and the two tanks are 

 connected with a pipe fitted with a valve. The cart outfit, which only 

 is taken into the orchard, weighs but a few hundred pounds. One 

 horse has no difficulty in handling it even over muddy or stony land 

 or on a steep hillside. The rig has no working parts to be interfered 

 with by low limbs or low-headed trees. As many lines of hose as the 

 operator chooses to work may be used at the same time. 



Of the practical working of this outfit Mr. A. I. Loop writes us 

 as follows : " Of course our pressure is more even and better than 

 can be had by any machine that pumps the liquid. It is steady, no 

 jerks or sudden changes. We usually start with 130 to 150 pounds 

 in the air tank and if there are no leaks in the air connections (we
