REMEDIAL AND PREVENTIVE MEASURES. 65 
run down the outside and reach such bugs as arc about the base of 
the plants. This treatment will kill the bugs clustered upon the corn, 
and in case of those on the way to the field, while it will not keep 
them out, it will cause a halt in the invasion, and thus give the 
farmer an opportunity to put other measures in operation, one of 
which will include the use of kerosene in another manner. If a deep 
furrow is plowed along the edge of (lie field, running the land-side 
of the plow toward the field to he protected, the furrow will form a 
temporary harrier to the incoming hordes. 
UTILITY OF DEEPLY PLOWED FURROWS SUPPLEMENTED BY THE USE OF 
KEROSENE EMULSION. 
In dry weather the sides of this furrow can be made so steep and the 
soil so finely pulverized that when the chinch bugs attempt to crawl 
up out of the furrow they will continually roll back to the bottom, 
where they can he sprinkled with either kerosene alone or with the 
much Less expensive emulsion, and killed. In case of showery weather, 
which prevents the sides of the furrow from remaining loose and dry, 
the bottom can he cleared out with a shovel, making it more smooth 
and the sides more perpendicular, thus rendering it so much easier to 
follow along the bottom than to attempt to climb the sides. If holes 
are (\\\<z across the bottom at distances of, say, 30 or 40 feet, the bugs 
will fall into them and can he 1 still more easily disposed of by the use 
of kerosene. That both of these measures are thoroughly practicable 
the writer has ample personal experience in evidence, and knows that 
under most conditions that are likely to obtain, prompt and efficient 
application is all that is necessary. During a few days this work 
w ill demand the closest watching and application, but fields of grain 
can he protected thoroughly and effectually if these measures are 
faithfully carried out. and the expense of time and money will be 
found to he less than in almost any other plan that has been up to 
this time discovered. In his own experience, in no case has a field 
attacked by a migrating army of chinch bugs come under the writer's 
observation, but that might have been saved from very serious injury 
by the prompt use of either of these measures, though under some 
condition- the farmer might find it advantageous to apply some of 
the other method- of protection here given. 
THE 81 RFACE AM) COAL-TAR METHOD. 
The objections made by farmers to the use of most forms of these 
barrier- is that the finest pulverized soil soon becomes incrusted by 
even the slightest rainfall and the hug- then pass over it without 
difficulty, while harrier- of hoards are expensive. J
