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 18S7, four had a larger area of com 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 had a 

 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 lauds 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
