MOTHS.
J. F. Magennis, A. G. T. of Fort Dodge, Iowa,
writes me as follows: "Editor, Technical De-
partment, Dear Sir: Will you advise me as to
the best method of preventing moths from set-
tling in pianos? Also, what is the best way of
getting moths out of pianos; that is, to say, what
preventatives should be used?"
The questions are simple enough, but they
cover, for all that, an amount of controversial
ground that is amazing. Frankly, I do riot know
a single topic coming within the purview of this
department concerning which there are more
varied and heated opinions.
The ravages of
moths within pianos are serious.
The annual
amount of moth damage, if it could be computed,
would undoubtedly turn out to be immense. A
certain preventive and cure are, without doubt,
among the immediate necessities of piano mak-
ing. But I fear that no panacea is likely to be
discovered for a while.
The common house moth is a boring insect.
It lays eggs in all sorts of woolen fabrics, furs,
and similar substances. To find a place for these
it tunnels its way through the fabric and thus cuts
out the fires of the latter until the interior is
entirely disintegrated and is ready to fall to pieces.
Now, it is obvious that possible preventive
measures must consider means for (1) keeping
the moth away from the piano, so that it will
not attempt to lay its eggs there, or (2) for kill-
ing the eggs before they can come to maturity.
The experience of those who deal with furs and
clothing in large quantities seems to point to the
fumes of camphor as being a more or less ef-
fective preventive to the laying of moth eggs.
Furs, of course, are generally stored away at
very low temperatures, which apparently have
much the same effect.
I know nothing better than the fumes of cam-
phor as a preventive of moths. In my opinion,
the use of camphor does more or less effectually
keep moths away. I do not know anything else
of which the same thing may be said, and which
is practical for the particular case of the piano.
With regard to the destruction of moths in a
piano that has been invaded by them, the problem
is not less uncertain. If I read Mr. Megennis
aright, he wants to know how to keep moths out
of pianos and also how to destroy them when
they are in. The preventive measure is equally
necessary in both cases, since after a piano has
been cleared of moths, it must be treated so that
the same trouble will not occur later. When a
piano is found to be damaged by moths, it should
be very carefully examined with a view of dis-
covering how far the insects have bored into the
hammers, the dampers, and such felts as are per-
manently glued on to the various parts of the
action. Moth-eaten punchings can be removed
and burned, but the job of re-hammering or of
putting on new damper and action felt is by no
means easy or agreeable. When I have had a
case like this, I have always, first, carefully
cleaned the action and key-frame of all remains
of moth eggs and have then brushed a strong
solution of corrosive sublimate over the wood ad-
jacent to the affected felts. The latter should
always be removed and burned up. Even if the
affected felts are in the action itself, it is far
