BANDING — DESTROYING BORERS 61 
cloth serves the purpose very well. Handy covers are made by cutting 
a barrel hoop into two pieces, crossing these at a right angle, tacking 
the ends to a second hoop, and covering this frame with cloth. Such 
frames may be packed away for storage, one within another, taking 
up little room. 
Wire screening may be shaped into cones, which are used in the same 
way as the cloth-covered frames, and have a similar advantage of 
packing away in small space. If galvanized wire is used and properly 
stored when not needed, it will not rust for several years; but the first 
cost is rather heavy as compared with cheesecloth frames. 
Destroying Borers 
Cutting out borers with a knife is a remedy that seems drastic, but 
it may be the only means of putting a stop to an injury that would 
otherwise prove fatal. 
Frequently, it is possible to kill the borer by probing the burrow with 
a soft copper wire. If the end of the wire is nicked, so as to give it a 
few rough barbs, it will bring the borer or a piece of him out with it, 
and the operator may thus know whether he has succeeded in reaching 
the culprit. 
If cutting is necessary, a sharp knife should be used and the course of 
the burrow carefully followed. In this way no more real damage will 
be done to the tree than has already been done by the borer itself. It 
is well to paint the wound afterward with a mixture of lead and linseed 
oil—not with ready-mixed paint, which is apt to contain injurious 
oils added as driers. 
Removal of Dead or Dying Limbs 
There are certain species of small borers that attack especially trees 
that have been weakened. Once started, they continue to breed in 
such places, rapidly killing the tree and spreading from it to others in the 
neighborhoed that do not happen to be growing as vigorously as might 
be. By prompt removal of the infested limbs or trees the pests may 
be eliminated and other trees near by saved from attack. This, in 
fact, is the only feasible means of control in the case of some insects,
