Prof. A. J. Cook, in Rural New Yorker, recommends Paris green 

 (one tablespoonful to two gallons of water), or the kerosene emulsion^ 

 as a. certain remedy for the grape flea beetle {Graptodera chalylea)^ 

 and the apple flea beetle {G. foUacea)^ and their grubs Pyrethrum^ 

 if fresh and used persistently, will also destroy the insects. 



THE doctor's PRESCRIPTION, 



"Nothing but a garden will do it. The pills and powders this- 

 medicine-case holds are no such panaceas for bringing the roses tO' 

 your cheeks or strength and activity to your system.-' 



COPPERAS AS A PREVENTIVE OF GRAPE ROT. 



I have reason to believe that copperas is a preventive of the grape' 

 rot. In a small vineyard in Massillon, Ohio, where a quart to the 

 square rod has been sown in July for three 3?ears, there has been no 

 rot, while other grapes in the same neighborhood have rotted more or 

 less every year. They formerly rotted in this vineyard. 



M. Crawford, Summit Co., Ohio. 



Salicylic Acid should not be used for preserving fruit in tin but 

 only in glass cans, so says the Philadelphia Press. We say, don't use 

 it at all either in tin or glass. Put the fruit in glass cans; scald them 

 well and seal them tightly, and it will keep till doom's day, and when 

 you eat it it will not turn your stomach into a drug shop. Be sure 

 that every chemical that will preserve fruit is not good for the human- 

 stomach, or for that of any other animal either, for that matter. 



KEROSENE EMULSION. 



Writing from Iowa a correspondent writes that last summer he saw 

 frequent mention of kerosene emulsion as an insecticide, and that he 

 has a curiosity to know how it is made. In answer we would say that 

 the simplest form is one-third kerosene and two-thirds milk. An- 

 other form is eight parts kerosene, one part soft soap and eight parts 

 water. Heat the soap and water to a boiling point, add the ker- 

 osene and remove the mixture from the fire. Add twenty parts of 

 water to this, and it is ready for use. It is applied with a syringe. For 

 many insects nothing is better, and it is neither expensive nor difficult 

 of application. 



HOW TO CRYSTALIZE GRASSES. 



Take one pound of alum to one quart of water and set it back of 

 the stove to dissolve, but do not boil, and when thoroughly dissolved
