MECHANICAL AREANGEMENTS. 



These are intended to act as barriers to keep away in- 

 sects, or as traps to capture them. They will be described 

 under the special insect which can thus be best treated. 



Machines For Applying Poisons. 



There are a great many kinds of machines and devices 

 manufactured and sold by dealers for applying insecticides 

 and fungicides, some of which are very good, and every 

 farmer, fruit grower and gardener should have at least one. 

 In order to save the purchaser time and trouble in making 

 a selection, a few of the more important machines are here 

 fio-ured, together with the price and manufacturers address. 



It is of course important, whenever possible, that one 

 provide himself with two machines, one for using a powder, 

 the other for syraying a liquid; but in case only one can be 

 purchased, a force pump and spraying nozzle should be se- 

 lected, since one can often mix the powder with the water 

 and apply it in this way. 



One of the best machines for dusting a powder on plants 

 is Leggett's Powder-gun. It works by turning a crank, and 

 throws the powder in a fine dust constantly and evenly, and 

 the supply can be easily regulated so that one or one-half 

 pound of Paris green or London purple can be evenly dis- 

 tributed over an acr^. This instrument has been highly 

 recommended by all who have tried it. The price of this 

 gun delivered complete with four extra tubes, shoulder 

 strap, oil can and all necessary attachments for distributing 

 the powder is $7.50. This machine can be purchased from 

 the makers, Leggett & Bros., 301 Pearl St., New York. See 

 fig. 1, 2, 3.
