of all ages, and does not Id jure half -grown 'corn if the fluid is 

 thoroughly aud repeatedly shaken up. Or, as a safer application, 

 an emulsion of kerosene may be made with a soap suds contain- 

 ing one pound of soap to twenty gallons of water. Two gallons 

 of kerosene oil should be boiled with a gallon of suds, and then, 

 while hot, thoroughly churned or mixed with a syringe or hand-force 

 pump until a permanent cream or butter is produced. This emulsion > 

 may be diluted with the soap suds at the rate of a gallon of the 

 former to fifteen or twenty gallons of the latter. 



9. TJie cqyplicaiion of rcpcllcni substances, to prevent the chinch 

 bugs from laying their eggs upon the crops; a measure suggested 

 only as worthy of experiment. A light coating of partly stale gas 

 lime, not too freely applied to wheat in spring, or placed by the 

 handful at the roots of corn at harvest, might possibly protect 

 these crops. 



10. Finally, the artificial cultivation of the germs of the con- 

 tacjious diseases of the chinch bug, with a view to spreading these 

 diseases at will by means of such artificial cultures. This is a 

 theoretical remedy only, and much additional study and experi- 

 ment will be required to put it on a practical basis. 



SPECIAL PROCEDUKE EECOMMENDED. 



For those parts of the State not already practically mastered by 

 the chinch bug, especially for Northern and Western Illinois, I 

 would earnestly recommend the following procedure for the com- 

 ing fall and spring: 



1. Give up w^heat, rye, barley, Hungarian, and millet, for the 

 coming year; or, 



2. If the just mentioned grains are grown, sow with them 

 timothy this fall, or clover next spring. 



3. Pick up boards, rails, and sticks along roadsides and around 

 headlands this fall, and thoroughly burn over the borders of the 

 fields and similar places, thickets, woodlands, etc., late this fall if 

 practicable, selecting for this dry days w4ien rubbish will burn 

 close to the ground. Such places as cannot be burned in fall 

 should be fired early in spring. 



4. Fertilize ground to be used next year for small grain or 

 corn, and apply to the surface next spring quickly acting fertilizers, 

 where crops become infested. 



5. Plant all the crops, except corn, at the earliest time per- 

 missible. 



6. Search carefully for the bugs next spring in their usual 

 quarters, as a means of determining the possibility of serious injury; 

 and, if this seems threatening, 



7. Kaise extensively, another year, crops not affected by the 

 chinch bug.
