176 DESTRUCTIVE INSECTS OF VICTORIA: 



of each of the cross arms to the dasher below, to which it gives a cradle 

 motion, thus moving the solution throughout at each motion of the 

 pump handle. The working of the disturber entails a little extra 

 labour, but it does not at all effect the pressure at the sprays. The 

 improved strainer is fitted, as shown in sectional view of the 

 Challenge. It is made of brass gauze, and the mesh is fine so as to 

 prevent small crystals or foreign matter from entering the pump, and 

 thus choking the sprays. The spray caps are movable so as to allow 

 of the easy removal of foreign matter should any possibly find its way 

 there.

The Challenge Spray Pump is exactly the same in detail as the 

 Deluge Spray Pump, but is of smaller size throughout. We have 

 brought this pump out mainly for orchardists and fruit-growers, for 

 whom the Deluge Pump is too large, and many of our other pumps too 

 small. We have spared no effort to make this pump a thorough success, 

 and the appreciation that it has already been met with is sufficient 

 proof to us that our efforts have not been in vain. It is fitted with two 

 lengths of hose, each 15 feet long, with treble sprays. Cocks are pro- 

 vided on the air chamber, so that either one or both hoses may be used 

 at the same time. The pump is made of hard gun metal, with gun- 

 metal valves ; it is of the double-action type, so that the spray is con- 

 tinuous ; it is fitted with a proper-sized copper air chamber. The suction 

 pipe is of copper. Our improved cradle agitator is fitted to this pump, 

 the motion being given by every movement of the handle by means of 

 rods connected to cross arms firmly fastened to the spindle of the pump. 

 It is also fitted with a large brass wire gauze strainer for straining the 

 liquids. The capacity is about 30 gallons. 



Price : £10 10s.

Knowles' Victoria Spray Pomp. 

 {See Fig. 9.) 



This pump — an improvement on the Excelsior — is now made with 

 a galvanized wrought-iron lever handle, which greatly increases its 

 power and ease in working. It will be appreciated by those who have 

 up to 5 acres of fruit trees under cultivation. It is fitted with a cover.
