Tracing the effect of the development of agriculture in Illinois 
upon the various classes of corn insects, the important differences 
seem chiefly due to two causes; the cessation of the prairie fires of 
the Indians and the general substitution of corn for the prairie 
grass. In the face of these autumnal fires no insect which by its 
habits was thus exposed to great diminution could possibly main¬ 
tain itself, unless, like the chinch bug and army worm, it had 
a high rate of multiplication. Such insects inevitably became the 
worst pests of agriculture.

Aery heavy rains in southern part of the State. Wheat on light 
clays materially damaged by chinch bugs last fall.

Says to newspaper reporter that chinch bugs in the county seem 
to have come through the winter in good condition, and that unless 
the weather should prove unfavorable they will probably do much 
damage. He urges burning over headlands and grassy tracts 
where they are collected in their winter quarters.

Danger of chinch-bug ravage has by no means passed. Where 
corn was generally destroyed last year, the second brood was cut 
short for lack of food; but where the damage was less serious the 
bugs have hibernated in threatening numbers. No unusual nat¬ 
ural check upon their increase has been detected. Quick, stimu¬ 
lating fertilizers are recommended for infested small grain not ab¬ 
solutely overwhelmed by attack, and a formula furnished by the 
chemical department of the University is given for trial; viz., “one 
hundred pounds each of nitrate of soda, superphosphates, and muri¬ 
ate or sulphate of potash, to be thoroughly mixed, and sown at the 
rate of from 150 to 300 pounds to the acre, the mixture costing
