ing farmer. Even a strip of plowed land, made perfectly level 
with a disk-harrow, and thoroughly rolled by a heavy roller 
and made dusty, will do wonders. All these methods have two 
ends in view: to stop the progress of the bugs, and to collect 
them in large numbers in a limited space, so that they may be 
killed. This latter can be done in various ways. If ditches 
are used, a little straw scattered in the bottom will soon be 
crowded with bugs; in fact, piles of straw seem to confuse the 
traveling bugs and retard and retain them for some time. The 
' straw can be burned by adding a little kerosine oil. Or, by 
means of a post-hole augur, holes can be made every ten or 
fifteen feet, into which the bugs will collect or into which they 
may be swept. By closing such holes where filled with bugs, 
and making other holes, or by killing the bugs in the holes 
with kerosine oil and cleaning them afterwards with the augur, 
the bulk of the army can be captured and disposed of. As the 
bugs will not cross coal :tar, the edges of furrows or ditches 
towards the fields to be protected should be covered with this — 
material, and none of the insects could leave the trap. This 
coal-tar can also be used even without a ditch or furrow, but 
will not be so effective; yet in certain and extreme cases it may 
be the only method that can be used in time. By pouring a 
broad line of this material upon the neutral zone between the 
fields, and by keeping its surface fresh, the bugs may be held 
in front and can be trapped in holes made for this purpose. If 
all such measures have been neglected, or if the bugs have 
already reached the outer few rows of corn, the plants in them 
should be cut down in such a way that they form more or less 
continuous piles upon the ground. The bugs, being starving, 
will not leave these stalks for some time, but will continue to 
find their sustenance upon them. This, for quite a while, pre- 
vents their moving to the next rows of corn. The bugs can be 
killed in very large numbers by burning dry straw between 
the piles of corn cut down. A little kerosine oil, or any other 
substance that burns well and makes a dense smoke, will make 
avery pleasing addition to the entertainment. Knowing the 
principle to be applied, every thinking farmer ought to know 
how to apply it to the best advantage upon his own fields. The 
very fact that the bugs are retarded for a long time upon the 
heated surface of the ground is sufficient to killa large number.
