the mixture begun W cOOA' O"o.
bases are cheese, corn meal, and
oil. Of rhodium; cheese, ground
fish. or meat and oil of valerian,
glucose and q small quantity OF
-four. Glucose makes an excep-
tionally good base, as when prop
erly mixed the poison thus pre-
pared ia noninfammable even
when heated. The liability to
spontaneous combustion OF phos-
phorus mixtures eliminates their
use in hay, grain, or other ware
houses or places where there Is
danger Of fire or the invalidation
Of insurance. 1t should not be
forgotten that phosphorus de-
teriorates very rapidly, especially
when it is exposed to the sun.
Arsenic Paste.
This consists of arsenious acid
combined with base Of cheese,
meal. or macerated fish. 1t may
be placed on raisins or prunes
and is to be recommended on ac-
count of its stability, the ease
with which it is handled, and the
absence Of danger from fire. IT
should, however, be distributed
with great care, every precautlon
being used to place it where 1t IS
inaccessible to children and do
nestle animals.
Barium Carbonate.
This has not proven an enec-
tive poison owing to the fact that
it is easily decomposed by the
vegetable acids, especially tactic
and oleic acid found in cheese
and oil. The poisonous effect is
not greatly altered by this change
A disagreeable metallic taste Is
produced and the rats will not
take it.
Strychnins.
Stryohnine is prepared as a
poison by soaking wheat over
night in water and subsequently
pouring off the excess fluid and
placing the wheat in = caldron
containing hot glucose and stryc'
MIA sulphate, the latter in the
proportion Of one-tenth OF l PEI
cent. After carefully stirring SC
that each grain is thoroughly
coated it is dried in shallow iron
pans over a slow FIRE with can
slant agitation of the grain, OF
by exposure on sheets or canvas
to the rays Of the sun. This mix
ture may be made much more Ell
ficient by the addition Of cyanide
Of potassium in the proportion Of
one-half Of l per cent. Poisoned
grain has not been found efficient
in the destruction Of rats, as it,
bitter taste causes them to. ea'
little or none Of it. It is how
ever, particularly efficient in poi
soning squirrels, rs it is takeI
readily by them. The chief Oh
jections to its use are its cost, dit
ficulties Of preparation, and liza
bility to its being taken by chick
ems. lAl
Carbon Bisulphide.
Carbon bisulphide is not q poi
son 80 much as an asphyxiant
As the name indicates, it is q two
to-one mixture Of sulphur ant
carbon. The resulting liqui,
preparation should be kept in air
tight cans, since it eyaporate
quickly. The principle of its ct
ficacy against rodents is that tn
fumes are heavier than air and
sinking into q rat or squirrel hole
drive out the necessary oxygen
To use bisluphide saturate
J. small pad Of some absorbent cot
| ton, jute, wool, or flannel mater
| ial with the. liquid, thrust this int
| the rodents barrow, and care
fully stop all apertures througl
which the fumes might escape
| Animal life. Of every sort in tina

In buildings the use Of carbon b
sulphids 10 greatly hsmpered b

BY stopping oil cracks and othe
Openings. Also the odors of d.
composition in animals 80 kihe'
stand againat its use anywher
but in the country.
Against rats and squirrels j
country places carbon bisulphid
has proved one Of the best Of al
weapons. Whore it kills, it kill
whole families ct Z time, not on
by one, a. must ever be the cas-
with other poisnos and with trap
or shotguns. Not only does it XII
the rodent but il also destroys tn
