 to be used. Dry mixtures are therefore employed, 

 being dusted over the plants. They should be 

 put on preferably when the foliage is still damp 

 after a rain or dew; and may be applied by use of 

 a very fine sifter. Metal canisters, having finely 

 perforated bottoms, are made and sold for this 

 purpose, to be used in the same manner as an 

 ordinary pepper caster. These will answer in a 

 small way only. 



A capital implement for applying dry mixtures to 

 field crops is the Farmer's Favourite Duster. 

 In operating this device, the left hand is held firm,

Any device such as described will, however, be
