In a former bulletin these sprayers were recommended as be- 

 ing almost indispensable. With greater experience we find that 

 so much hard, dirty work is involved in their use that we do not 

 feel like recommending them except in cases where bucket and 

 barrel pumps cannot be used to advantage. 



Knapsacks may be obtained of most dealers in spraying sup- 

 plies at a price ranging from |10 to 115. 



Powder Guns. 



Powder guns are used to apply poison and repellents for 

 insects in the green-house or on small plantations of fruit or 

 vegetables. The well-known Leggett Powder Gun may be taken 

 as an example of these guns. It consists of a reservoir and an 

 inclosed fan operated by a crank, which blows the powder out 

 through a tube. It is supplied with a number of nozzles and 

 tubes which are used in the different kinds of work. It is made 

 principally of tin, and weighs about five pounds. 



.Some manufacturers assert that these guns are just the thing 

 for poisoning bugs in large potato fields, using the clear Paris 

 green. Most fungicides cannot be applied in a dry form, and 

 since it is often advantageous to use both insecticides and fungi- 

 cides it would seem to be better economy where a large amount 

 of w^ork is to be done to invest in a machine that will apply a 

 remedy for both insects and diseases at the same time. 



The Lightning Potato Bug Killer. — This little contrivance is 

 quite convenient foT applying pioison and repellents for insects 

 in the green-house or in small plantations of fruit or vegetables. 

 It consists of a small hand bellows with a funnel-shaped spout. 

 The material to be api>lied is poured into the bellows through 

 the spout, through which it is puflied out in a cloud-like form. 

 Where small amounts of tobacco dust, pyrethrum, hellebore or 

 Paris green are to be applied this bellows will be very useful. 



These implements may be obtained from dealers in florists' 

 supplies at a small cost.
