“All the attempts to check the depredations of the Chinch-bugs by 
throwing offensive substances upon them, such as tarred saw-dusf salt 
or lime, have proved to be labor lost. The recommendation of ^lt a? 
plication had the run of the newspapers the past season. Both this 
and the air-slaked lime were thoroughly tried by Mr. Sells of Bloom¬ 
ington, without making any perceptible impresssion upon’the bu<*s.” 
I most heartily agree with Dr. LeBaron in regard to topical appli- 
° f somethin g that will destroy the crop P will 
fail to destroy the bugs, except water. After they have once entered 
the grain field in full force there is nothing which has yet been sug¬ 
gested that will destroy them except submerging in water unless it 
be some such agent as fire, which as a matter of course destroys the 
3rop. When they attack the corn it is possible by great ffi and

The suggestion by Dr. LeBaron to refrain from planting certain 
:rops is one no likely to be put into practice even should it appear 
y expenence to be a somewhat effectual remedy. But as it would 
:ertainly not cause the pest to become extinct, the remedy is tooco^tlv 
'hen the chances that the pest will not appear the very season the 
oeasure is adopted, are about equal to those that it will be abundant

Clean farming is the best under all circumstances, and if adopted

Iso aid m the same direction. But one of the best methods to prevent 
heir increase, is diversified farming. Massing crops in immense 
odies and cultivating the same thing year after year dm 3 
jmds to increase the insects that feed on these crops. So W as 
his violation of natural laws, and I might say the true theory of'the
