Compressed Air Sprayer Being Loaded. No. i. 



The illustration shows a gasoline engine compressing the air into one of two tanks on the waggon and 

 filling the second tank with the mixture to be used. The tanks contain about loo gallons each and it takes 

 lo to 15 minutes to fill them. The air tanks are charged up to 160 to 180 pounds pressure to the inch. 

 When this_ compressed air is turned into the tank containing the mixture the liquid is forced out in the 

 form of a fine spray. (See article by Mr. J. Tweddle, in this issue )

 This saves at least 

 25 per cent, in ma- 

 terial and enables 

 ten times as much 

 surface to be 

 sprayed as can be 

 done with the hand 

 sprayer with 3 or 

 4 nozzles. 



The horse or 

 team going at a 

 good lively walk 

 can do a large 

 amount of work 

 in a day. Twenty 

 to 30 acres of 

 average sized ap- 

 ple trees can be 

 sprayed, using 

 1,500 to 2,000 gal- 

 lons.

Power Sprayer Here to Stay 



JOSEPH TWEDDLE, ERUITLAND, ONT. 



HAVING leased some 60 acres of my 

 neighbors' apple orchards, and 

 knowing the need of thorough spraying, I 

 found the hand sprayer quite inadequate to 

 do the work in the time allowed. A com- 

 pressed air outfit, as shown in the accom- 

 panying illustration, was secured. It has 

 all the latest improvements, including the 

 Owen's spar and a hoist of my own inven- 

 tion for use on high trees. 



This hoist does away with the use of the 

 clumsy and dangerous derrick and the heavy 

 labor called for in its use. By the present 

 arrangement the nozzles, %Vhich are about 9 

 inches apart, and in a perpendicular line, can 

 be made to cover the tree thoroughly and at 



work. The opposite 

 side of the trees is covered when the wind 

 changes, which usually occurs in good time 

 to finish the work when required. 



POWER SPRAYERS. 



The power sprayer has come to stay. The 

 past two seasons have been productive of 

 much scab on apple foliage and fruit where 

 no spraying was done. It is not, however, 

 difficult to procure 80 or 90 p^r cent, of 

 strictly clean fruit by spraying three or four 

 times with Bordeaux mixture and white 

 arsenic or arsenate of lead. Fruit from 

 trees so treated has realized double to treble 

 the net price that unsprayed fruit has 

 brought. Nothing pays such handsome 

 dividends as the power sprayer. It doubles 

 both the crop and the price.
