is unheard of. Practically the same state of affairs existed in 1888, 
both as to crop and bugs. In the twelve counties more or less infested 
with bugs in 1887, four had a larger area of corn than of small grain, 
and all but seven showed a greater area of corn than wheat. In 1888 
only three had a greater area devoted to wheat than corn, and six hada 
greater area of corn than of small grains. It will be observed that Sul- 
livan County, which probably suffers from Chinch Bug injury as bad as 
any portion of the State, is one of these. It appears therefore that the 
nature of the crop has of itself nothing to do with the distribution of 
the Chinch Bug in Indiana.

Neither can this unequal distribution be attributed to the interspersion 
of timber Jands among the cultivated fields, as the northern and south- 
ern portions are about equally wooded, and, besides, the treeless 
prairies of the State are not particularly subject to invasions of Chinch- 
bugs. Low temperature can hardly be held responsible for the phe- 
nomenon, as the ravages in more northern localities like Nebraska, 
northern Iowa, and in Minnesota will attest. Coming northward from 
the Ohio River, during the season of drought which has occurred each 
year since 1886, one can not help but admit that the effects of dry
