CarbOlic Acid. Dissolve six ounces
of Carbolic Acid in each gallon Of
hot water which makes approx
mately per cent solution. and
spray. Carbolic Acid, however, 10
too expensive at present and may
be substituted by Soluble. Crude
Carbolic Acid. 1t must be remem-
bered that these drugs are active
poisons and must not be sprayed on
feed.
Some other reliable disinfectants
are, Compounded Solution Of Gre
sol (U. S. P.) in a per cent solu-
tion Tor about five ounces to each
gallon of water) and Cresol in q
z per cent solution Tor about % OF.
to each gallon Of water). The lat
ter has the disadvantage of being
somewhat difficult to dissolve. 1t
disolves, however. easier in warm
water.
For the exterior of buildings,
manure piles, open sheds, stock
pens, barn yards and other grounds
a combination of Crude Carbolic
Acid and Chloride Of lime makes a
satisfactory disinfectant. 1t should
not be used on b e interior Of
build ngs or closed spaces, where
there is no suffeciency Of air, be-
cause the fumes given off by the
Chloride Of lime are irritating and
poisonous to those who attempt to
use it. In applying it bear in
mind this poisonous character.
The application of these disin.
fectants requires the use Of spray
pump, which should be equipped
with about fifteen feet of hose to
which is attached a five foot iron
pipe Of the same caliber. 1t is
advisable to add in the solution a
moderate amount of unslacked lime
which not only increases the germi-
cidal power Of the disinfectant,
but also it marks where the dlsin-
fectant has been applied.
For tight buildings such as milk
houses, cellars, granaries, barns.
ETC., there is nothing better and
more convinient to use than Form
aldehyde gas. In fumigating with
this, use the following procedure !:
Close and seal all doors. windows
and other openings, leaving open
only one door for the escape Of the
person who applies the disinfect-
,,,ant. Then place p metal container
with water ina spot preferable on
concrete, on sand or on the ground)
not distant from the open door.
Within this container place a Sec
ond metal container with the prop
er amount of Formalin. This con-
tainer should not he full. because
some Of the Formalin may escape
when it boils. Have in a bottle
with wide mouth the proper pro-
portion of Permaganate of Potash,
empty it into the Formalin contain
eras quickly as possible and run
out through the door, closing it.
The proportion used is. Formalin
five parts to two parts Of Permaga-
nate of Potash, twenty ounces of
Formalin being required to disin-
feet 1000 cubic feet of air space.
Do not place the disinfecting apar-
atus in proximity to anything in
flamable or explosive as the combin-
alton of the formalin and Permaga-
nate Of potash is attended by the
production of q tremendous amount
Of heat.
On account of the high price of
Permaganate Of Potash. the Chicago
Health Department recommends
Chloride Of Lime as a substitute,
1.-TWO parts Of Fogmalin to one part
Of Chloride Of Lime). The Chlor-
ide of Lime is made into q paste,
put in the container and over it
the Formalin is poured in the same
manner as above.
The time of exposure depends up
on the nature Of the disease. Un-
der ordinary conditions six hours
is sufficient, The efficiency Of For
malin is increased by warm and
damp weather. After six hours Of
exposure. open all doors and win
ows and let the building be we'll
ventilated.
Manure. after it has been disin-
fected, may be hauled and spread
upon field to be plowed. This
field should not be accessible to
animals.
Where this is not possible, it may
be hauled to q convenient spot and
disinfected, then strong pig-proof
fence should be built around it..
After the removal of this pile the
ground should be disinfected.
Where haymows, haystacks, and
straw stacks have been infected by
diseased animals feeding upon them,
