REMEDIES. 401 



6. — Thorough ventihition is important, as I have reason to 

 believe that at least part of the wheat is infested before it 

 reaches the granary ; therefore the necessity of preventing the 

 eggs from hatching. 



D. — Clean thoroughly, as directed in Remedy No. 75, and 

 provide against a high temperature, and good results will follow. 



E. — Grain kept in bulk should be turned over occasionally 

 by shoveling, to prevent becoming heated. 



F. — Stored grain should be kept free from damp, and kept 

 perfectly covered, to prevent becoming wet from rains, etc. 



REMI5DY NO. 77. 



Coal oil or kerosene emulsions. Personally, I am o^jposed 

 to the use of mineral oils on trees or foliage, but deem it proper 

 to give Professor C. V. Riley's remedy for scale insects, known 

 as the " Kerosene Emulsion," which he reports as giving excel- 

 lent results. It is as^foUows : 



"The process of forming a perfectly stable emulsion of ker- 

 osene and milk is comparable to that of ordinary butter-mak- 

 ing, and is as follows : The oil and milk in any desired pro- 

 portions are poured together and violently dashed or churned 

 for a period of time varying with the temperature from fifteen 

 to forty-five minutes. The churning, however, requires to be 

 more violent than can be effected with an ordinary butter 

 churn. 



" The Aquapult force-pump (the Gregory pump will answer 

 this purpose. — ^I. C.) may be used satisfactorily for this pur- 

 pose where moderate (piantities are only required. The pump 

 should be inserted in a tub or pail containing the liquid, which 

 are then forced into union by continuous pumping back into 

 the same receptacle through the flexible hose or spray-nozzle. 

 * * * On continual churning through the pumps, the 

 liquid finally curdles and suddenly thickens, to form a white 

 and glistening butter, perfectly homogeneous in texture, and 

 stable. This kerosene butter mixes readily in water, care being 

 taken to thin it first with a small quantity of the liquid. * *
