"The use of keroseDe can hardly be expected to prove of value 

 except when the bugs are massing on corn. At this time, appli- 

 cation to an acre or two of the field next to stubble may do much 

 to save the rest of the field." 



Prof. Osborn estimates the necessary cost of a thorough spray- 

 ing to be about seventy cents an acre — thirty cents for material 

 and forty cents for labor. 



Prof. Atkinson also reported "perfect success" with the same 

 application, reaching the conclusion that "there is no reason why 

 all should not get rid of the chinch bug on corn, for a failure to 

 kill the bugs would arise from some fault in the application, and 

 the application can be made cheaper than a dressing of the corn 

 could be made with a hoe." 



Prom the office correspondence the following items of interest 

 are taken. 



Mr. L. B. Sidway, of 182 Dearborn Street, Chicago, writes under 

 date of August 6, 1888, as follows: — 



"I have seen the kerosene emulsion, as recommended on page 

 41 of your report on chinch bugs — 1888 — tried with these results: — 



"1. F. Hultgren, Verona, Lawrence Co., Mo.: 



"At the beginning of wheat harvest the bugs went into his cornj 

 and he at once applied the emulsion. The bugs not killed left 

 he field. 



"2. G. D. Sidway, Purdy, Barry Co., Mo.: 



"The bugs had got into first four rows of corn. Applied emul- 

 sion and supposed all were killed. Two days later found them a 

 little farther in the field, and applied emulsion — beginning two or 

 three rows ahead of any bugs — and has seen no more in the field. 



"3. At my own place, Godfrey, Madison Co., 111.: 



"The bugs had gone into corn about thirty rows, and were in 

 great numbers. Applied emulsion and have seen no more bugs — 

 now two weeks. 



"I think this formula a cheap, easy, and very efiPective method of 

 killing the chinch bug in corn. Its use may easily be worth more 

 to Illinois in one year than the Agricultural Department costs the 

 State in twenty." 



A farmer of Edwards county. Dr. Bristow, living near Albion, 

 reported personally that he had protected his corn by the use of 

 the kerosene emulsion diluted to contain four or five per cent, of 

 kerosene, applying it twice a day to the four or five outer rows, 

 covered with bugs from wheat adjoining. The insecticide was ap- 

 plied at first with a wisp of broom corn, but afterwards simply 

 thrown npon the stalks with the hand.
