Where only few small machines

suits in Matching may be secured i'm
cellars as well as i'm rooms, and these
are more commonly used Many of
these cellars are provided with some
system of ventilation beside window,

providing good ventilation without

How 70 Operate Machine.
In setting up the machine, get it per-
fcctll level. DO not plane off the door
If it sticks, until the machine has been
heated up and thoroughly dried Run
the machine at about 1O2OI'. for a day
before putting in the eggs Afterwards
do not touch the regulator for several
hours as il takes his time for the ma
chine to come back to its regular tenn
pcraturc
Tho temperature should remain
nearly even. When tie bulb OF tn"
Thermometer rests directly ON tho EGGS
Che temperature is usually held At
lOl 20 To 1920 r. the inst week. 1920
to 1880 +, the second week, and 1880
+, the last week; while a hanging
thermometer is operated at about
1920 to lO2l2o +. the first two weeks,
and 1880 f.. the last week.
The eggs tend TO throw off more
heat as they develop, SO that OCCASION
ally the regulator needs to he changed
slightly, but it should not be changed
any moro than is absolutely necessary.
The temperature Of the egg chamber
may be lowered by lowering the flame
of the lamp in the middle of the day.
Regulate the incubator before opening
the door To tend to the eggs. Most OPP
orators tend To their machines two or
three times daily.
rho .r IL I,
discussed question. which depends on II
great variety Of circumstances y poor
hatch is more apt to be due to the con-
dition of the eggs previous to Matching
than to incubation, although improper
handling of either factor Will produce
the same results. When eggs fail t.
hatch, see whether the breeding stock
is kept under conditions which tend to
produce strong. fertile germs in the
eggs. if the eggs have been handled
properly before incubation, and
whether the conditions were right dur
ing incubation, as judged by the time
OF the hatch.
\ daily temperature record should
be kept Of each machine. The opera
tor can thus compare the temperature
at which the machines have been kept,
which may prove valuable i'm the flu
ture work, especially If the brooder
records can he checked back against
those of the incubator.
Every poultry raiser who contem-
plates setting up an incubator is adj
vised To write for the new bulletin, to
the United State department of agri-
culture. Washington, ID. G. Among
other details it has paragraphs on
moisture and ventilation, testing eggs,
and disinfecting and storing incubat-
ors.
