SPRAYING APPARATUS. 37 



The " Strawson " ■sprayers, manufactured by Mackieis, 

 Ltd., Pleading, are also excellent hand-power machines. 

 One is. the "Portable Fruit Tree Sprayer," a light 

 machine, not mounted on wheels, but provided with four 

 handles to enable it to be easily moved about by two 

 men. A powerful brass pump is fitted to a horizontal 

 18-gallon barrel, mounted on an iron frame, and two 30ft. 

 lengths of delivery hose, fitted with brass lances, cocks, 

 and nozzles. This, machine is capable of delivering the 

 spray to tall standards. They also make a smaller 

 machine, to run on four small wheels to be drawn by hand 

 or a pony. This is known as the " Small Fruit Tree 

 Sprayer." 



Knapsack Sprayers.— Here we have a type of 

 machine that will suit the requirements of owners of small 

 gardens. They are made in various forms, but all are 

 constructed so as to be carried on the back, one hand 

 operating the pump and the other the delivery hose. 



Messrs. W. Weeks, Ltd., Maidstone, make what they 

 term an " Improved Knapsack Sprayer," capable of hold- 

 ing 3| gallons of fluid, and weighing when full 141b. It 

 is strongly made, is very duiable, and reasonable in cost. 



Messrs. Ph. Mayfarth and Co., Bunhill Row, London, 

 E.G., have a knapsack sprayer called the " Syphonia," 

 which autom.atically delivers the fluid without the aid of 

 a pump. It consists of two parts— the tank, or sprayer, 

 and a force pump. The latter has to be fixed to a tub 

 containing the fluid, and is then connected to the tank 

 when to be filled. First of all air is pumped in until the 

 pressure gauge registers 151b. pressure, then the fluid is 

 pumped in until the gauge indicates 451b., when the tap 

 is turned off and the delivery hose adjusted. When re- 

 quired for use it is only necessary to turn the tap slightly 

 to deliver the spray with great force. Can be used by a 

 m.an or youth.

 also make a handy and efficient machine, known as the
