190 DESTRUCTIVE INSECTS OF VICTORIA: 



Danks' Sprat Pumps. 

 {See Figs. 9, 10, 11, 12, and 13.) 



Handy Spray Pump: This pump (see Fig. 9) is strongly made. 

 The tube which forms the piston rod is arranged so as to act as an air 

 chamber, giving a continuity and evenness of spray. The pump is 

 screwed to an iron plate, the projecting portion of which forms the step 

 plate shown in Fig. 9. By this means the whole affair is made 

 thoroughly rigid, and the continual buckling to and fro of the bottom of 

 the tank is an impossibility. 



Price: £2 10s. 



Acme Spray Pump: This sprayer (see Fig. 10) is suitable for 

 medium sized orchards and vineyards, or in cases where it is not 

 convenient to take a cart. Two lengths of hose, each 15 feet, and 

 quadruple sprays. 



Price: £13. 



KnapsacTi, Lever Spray Pump : This pump (see Fig. 11) is strongly 

 placed, and the tank is constructed so as to be comfortable to the back. 



Price: £3. 



Champion KnapsacTi Spray Pump: In this pump (see Fig. 12) the 

 lever is absent, the action is readily understood from the engraving. 

 The piston is arranged to act as an air chamber. The pump itself is 

 thoroughly rigid. 



Price: £3. 



Deluge Spray Pump: This pump (see Fig. 13) has been specially 

 designed for the larger growers. The pump, which is on the semi- 

 rotary principle, is very powerful, and would, if necessary, supply more 

 jets than shown in our engraving. The air chamber is large, and the 

 arrangement for distributing the liquid is very simple. The pump, 

 which may be worked by the driver as shown, has an arrangement of 

 taps whereby the liquid may be turned on to one or both of the sprays, 

 or, when necessary, turned into the return pipe so as to thoroughly 

 disturb the liquid. Two 20-ft. lengths of hose and the necessary 

 directors and sprayers are supplied with this pump. 



Price: £17. 



Knowles' Pump and Sprays. 



{See Figs. 14, 15, and 16.) 



The "Knowlesly" Special A1 Spray Pump. 



This pump has been specially designed for those fruit-growers who

 "Improved spray pump" described on page 129 of the first volume of 

 this work. 



It may be fixed in a vessel of any shape, holding from 10 to 100 

 gallons ; but for general requirements they are sent out in a 10 gallon
