INSECTS THAT EAT cuRIos.

How the OHcers of the Smithsonian IN.
stitutlon Combat Foes.
Bugs are source of much anxiety and
annoyance to the curators Of birds and
mammals at the Smithsonian institution
and in the National museum. II given
a chance they would gobble up the dead
and stuffed creatures, not even sparing
the bones and the beaks. Accordingly,
those in charge have to be perpetually
on the alert to combat these small but
not contemplate foes.
If stuffed specimen" is thoroughly
poisoned with arsenic when it is pre-
pared there 10 little or no danger that it
will ever be attacked, but the collections
in charge of Secretary Langley are gath
cred together from all parts of the world
and very many of the contributions are
not properly protected in this respect
This is true particularly Of those which
come from the tropics, where peppers
and pungent spices are considered sufh-
cient for purposes Of preservation.
So they are for awhile, and then, tho
spices having lost their strength, the
enemy begins to get in its work. Not
only does this happen with stuffed birds
and beasts, but the skeletons that reach
the institution with the flesh roughly
chopped of them and folded up in the
smallest possible compass for Transports
ton are frequently so poorly protected
by poisoning that maggots get at them
and eat the ligaments which join the
bones SO as to seriously injure their use
fulness.
Three kinds of insects threaten the
stuffed collections. One is the familiar
moth, which eats the feathers or hair
down to the skin and leaves unsightly
bald patches. Another is the 'dermes-
tes." or common "lard BEETLE" which
attacks and eats holes in the fatty skins
But worse than either Of these is the
"anthrinus" "a beetle about the size Of a
No. shot. and so small therefore that it
does not render itself evident and is not
readily found when sought for.
1t is vefytfond of anything horny, and,
getting chance at bird. it will begin
by eating of the covering of the bill, de-
nuding the legs afterward and chewing
up the shafts Of the bigger feathers. Il
it has an opportunity. it will regularly
honeycomb the horns of animals fres-
coed for museum purposes
OF course it is understood that these
three bugs do all the damage in the lar
va stage Of their being-that is, while
they are yet worms. Another sort of in
sect gets into empty eggs and eats up thu
lining membranes, where careless col
lectors have left them inside, as they
should not do, but it cannot injure th'
shells and does no harm. except to MAKE
litter.
| The best remedy, or preventive, know
is bisulphide of carbon; but it has 9
horrible smell that Curator Ridgwa.
will not use it for keeping the birds un
der his charge. He prefers to employ tn
next best thing, which is naphtholine,
product of coal tar. A handful Of crys
tails of it will kill case full Of insects
It has the disadvantage of irritating th
breathing passages, producing chroni
catarrh. Curator of Mammals True pre-
fers the offensive bisulphide of carbon.
A great many things besides beast
and birds at the National museum hav
to be protected from insects; for exam
pie. the costumes of all nations and othe
dry goods of every kind, which afford a
agreeable diet for devouring bugs. It
no small task to protect these perishab
articles from the attacks of many legge
scavengers with stomachs for anythin
. short Of metal and no respect for Il
most sacred Of curios. w ashington Sta
