J oiiriial of Agric/illiire, Victoria. 



[lo Feb., 1911. 



The larger machines were charged with 40 gallons of the copper-soda 

 mixture and the application of the spray, together with its regular distribu- 

 tion over tlu; crop, was closely followed by over 200 farmers. Each 

 machine sprayed five rows at a time and 100 gallons would cover from 

 I to i|- acres. Of course, more extended trials would be necessary to 

 test the capabilities of each machine for spraying cheaply, quickly and 

 effectively and no attempt was made to place them in order of merit, 

 although the performances of each were keenly discussed. 



The following machines were exhibited in action and the accompanying 

 photographs will give a good idea of their general structure and mode 

 of working. 



I. Knapsack Sf ravers. — A copper Knapsack Sprayer is shown, capable 

 of holding 5 gallons and is to be preferred to one made of galvanized iron, 

 because the iron extracts the copper from the mixture and thereby renders 

 it less efficacious. The cost is from ^3 upwards. 



The other represented is known as the ' ' Auto ' ' Safety Sprayer and is 

 made of galvanized steel, with asphaltum paint inside. The cost is jQt, 

 for 2 -gallon size and ^6 for 5-gallon size. 



L. B. &. D. AUTOMATIC HORSE SPRAYER. 



2. Forhes-Chislwlni Horsc-poivcr Sprayer.- — This machine is made at 

 Bungaree and when barrel is full, containing 100 gallons, weighs 11 cwt. 

 It is built on steel wheels with steel axle adjustable, also fitted with ratchet 

 gear for turning and driven with chain from centre of axle off sprocket 

 wheel. The pump is driven with eccentric and can be used to fill the 

 barrel instead of bucketing, thus saving time and extra help. The pump 

 is brass lined, double action and fitted with air-chamber, a continual stream, 

 of water being forced back into the barrel ; the solution is thus kept well 

 agitated. The machine is adapted to do 5 or 7 drills at a time and the 

 nozzles are adjustable. The spray is circular and can be regulated to any 

 angle. The droppers of the sprayer are fitted with swivel joints and are 

 not injured by striking any obstacle. 



Every machine is thoroughly tested before being sent from the factory 

 and the complete cost is ^25. The machine has been iminrned upon 

 since photograph was taken. 



3. Fleming^ s Horse-power Sprayer. — This is a comparatively light 

 machine as the weight is about 10 cwt. when the barrel is full. The
