INJURIOUS INSKCTS OF hkm. 157 



When it begins to slack stop pouring and begin again when 

 necessary to keep up the slacking; the idea being not to allow 

 the water to drop down through the sieve or to put on enough 

 water to cause the lime to become putty. '•' * * About 3 

 quarts of water is required to properly slack the 10 pounds of 

 lime. After the lime is all slacked and has been sifted through, 

 cover the box into which the lime has fallen and allow it to 

 heat for a time. " " '■' This may be now kept indefinitely in 

 a dry place. When one wishes to spray for a biting or chew- 

 ing insect, all that is necessary is to thoroughly mix a pound of 

 Paris Green with 20 to 40 pounds of the powdered lime. Fill 

 the machine and apply." 



A more simple wa^-^ of slacking the lime may suggest itself 

 to any party intending to use the dust spray.

A TROUBLESOME MITE. 



In March we were appealed to by a firm dealing in wholesale 

 groceries, which was troubled by a small mite afifecting boxed 

 figs from California and evaporated apples from the east, stored 

 in the firm's warehouse. A visit was made to the establishment 

 and boxes of the above named fruit found swarming with this 

 pest, which is shown much enlarged in Fig. 99.
