16 INSECTS INJURIOUS IN 1902. 
REMEDIES AND MEANS OF PREVENTION. 
We do not know of any practicable means of killing the Chinch 
Bugs in the grain at present. In this connection we will say that 
the sending out of diseased Chinch Bugs has been abandoned, it 
having been found that the results were not sufficiently practical. 
The insects however may be trapped and killed without much la- 
bor after they leave the grain and start to attack the corn. Plow 
a furrow around your corn in such a way that the steeper side is 
towards the corn; drag a small log back and forth in this furrow 
until it becomes very dusty; it must be kept dusty. With a post 
augur bore holes ten or twelve inches deep or even less, along the 
bottom of this burrow at intervals of about a rod. If the furrow 
is well made the bugs cannot cross it and finally collect in the 
post holes where they may be killed by kerosene or hot water. 
In wet weather a dust furrow is impossible. At such times the 
bugs may be stopped by means of a tar line. 
Tar can be purchased of the Minneapolis Gas Company for 
$4.50 per barrel, barrel included; for $3.75 per barrel without 
container. Pour tar to the width of two or three inches next your 
corn field or upon the side of the field attacked by the bugs. While 
this tar line remains sticky bugs will not cross it. The first tar 
applied will sink into the ground probably and the line will have 
to be renewed occasionally; that is it will have to be kept sticky. 
Bore post holes at the side of the tar line away from the corn 
and the bugs traveling along the line to find a means of crossing 
will fall into these holes where they may be killed. Even if the 
bugs have reached the outer rows of corn they may be stopped 
by the dust furrow or tar line between these outer rows and the 
remaining corn. The bugs on the outer rows may be killed with 
kerosene emulsion, one part emulsion to ten parts of water. Pure 
kerosene may also be used if one does not care to save the corn. 
It is certainly desirable to kill these bugs on the outer rows thus 
lessening the bug crop the following year. 
It has been claimed that a rope kept saturated with kerosene and 
placed on the ground on the side of the corn which is being at- 
tacked, will form an obstacle which they will not readily cross. 
Some stock will not eat the stalks covered by the bugs, and even 
if they did the majority of bugs would escape to perpetuate their
