NECESSARY OUTFIT. 



For (he small orchard, any good force pump mounted on a barrel, 

 the same placed on a sled or wagon, several feet of good hose, and 

 one or more good nozzles on the end of the bamboo rod, together 

 with a kettle, a couple of mixing tanks and the outfit is complete. 



My outfit consists of a series of platforms built against the side 

 of a hill. The lowest platform is high enough so that the material 

 runs by gravity into the spraying tank which is mounted on a wagon. 

 On the same plane with this I have a 75 gallon kettle with furnace, 

 and on this platform two mixing tanks holding IGO gallons each, 

 fitted with a gate valve (two inch) for rapid filling into the tank by 

 gravity. This avoids all slop and loss, and it will fill a 100 gallon 

 tank in a few minutes. Then above this is another platform with 

 large tanks for holding water which can be conveyed to kettle. 

 Mixing tanks or sprajang tank through hose by gravity. 



The portable part consists of a low down wagon, front wheels 

 24 inches, back wheels 30 inches, with 4 inch tread. Over this I 

 have a platform 5^ feet wide by 12 feet long. On the front end is 

 a box seat for driver. In this box is a six-cell dry battery and room 

 for necessary tools and fixtures. Back of this is a two-horse dou- 

 ble cylinder gasoline engine and on the rear end is a 100 gallon 

 tank with a good pump mounted thereon. The pump is run by be- 

 ing connected to a jumping-jack suspended overhead by means of 

 an elevated platform supported by four well braced posts. This 

 jack is connected to the engine by a three inch belt. The gasoline 

 tank is also above, out of the way. Every part is under immediate 

 control of the driver without moving from his seat. The valves 

 controlling the engine are within easy reach. The switch board of 

 battery is on back of the seat. The belt lever within easy reach 

 above his head. The pump can be stopped instantly by turning 

 to the loose pulley. The pressure is held uniform by an air chamber 

 in which pressure is maintained at 80 pounds. This is controlled by 

 a safety water relief valve which, when pressure reaches above 80 

 pounds, opens and leaves a portion flow back into the tank without 

 in any way causing any variation in the flow of the spray. This 

 pump runs 50 strokes per minute. With this I can with one hose 

 and four nozzles put on 100 gallons in a perfect mist in a very few 

 minutes. If I use two sets of hose and eight nozzles, in half the time. 

 To this pump we use a 40 or 50 foot hose. On the end of this is a 

 bamboo pole with a brass pipe through the center, a stop valve at 

 the bottom and four Vermorel nozzles at the terminal end. This 

 completes the outfit, and a very satisfactory one it proves, doing 

 away with half the terrors of spraying. The man holding the noz- 

 zles should have a pair of rubber gloves, a pair of goggles and a
