the temperature running uni
fOrmly at 1O2 degrees That IS little
TOO low to continue very many Gays
and vet Il is dangerous TO tell an ANA
teur TO raise it. for the reason that he
is prone to raise it too much Even eN-
perts err on the side Of too hlgh tenn
perature- The hen errs on the other
extreme and, If unuSIurpeQs almost IN
variably pulls off good matches. She
will leave the nest for two or three
hours at a time and still hatch ali the
eggs, but one was never known 70 over
heat the eggs. Nature, knowing that
this would be the case, provided the
egg with resistance against chill but
not against excessive heat, ana yet the
average incubator operator IS afraid OF
chilling the eggs, but VIII allow the
Thermometer TO run for considerable
periods of time two or three degrees
higher than nature ever INTENDED shoulo
be applied TO an egg
Care Is Needed.
Great care should be taken that the
temperature at the top of the eggs
should never run higher than 1OS de-
grees. Better lower than hlgners Ihan
that mark If you would get the nlBnesI
percentage Of hardy, liVable chicks. In
q careless way I have had lncubators
TO run for brief periods as hlSn as l1V
degrees and Matched a few chicks, hut
] always felt that their vitality nad
been impaired and think know that
every time the temperature reaches
even 1O4 degrees, it means Few more
chicks dead in the shell
Ventilation Important
Another important matter frequently
overlooked IS ventilation Few machines
are properly equipped Tor II An eSS
exhales carbonic acid gas IN increasing
quantity as incubation progresses, ana
this gas must be removed and its place
supplied with pure oXygen-lauen ar.
in my opinion, lack Of ventilation IS
the cause of more dead in the sheu'
chicks than all other causes combined
All through the process Of incubation
the proper circulation Of air should De
looked after, and more especially ~nen
the eggs begin to pip and hatch Inc
moment an egg IS plppeds there IS a 1T
he nose there exhaling Vitiated air
from a pair OF little lungs, and with an
incubator ru1l of the little air poison
ers. is IT any wonder that with improper
ventilation very many OF the more Zee

Everybody knows that the chlck
nursery under the egg tray as found IN
most incubaUOrs is 10 degrees cooler
than the egg tray-much too cold Tor
the little chicks-and yet you can look
at the little fellows at any time IN TINS
nursery and you will find them with
their little bills against the glass door
painting as If they were IN a IeInpersl-
lure 10 degrees too hot instead OF that
much too cold. Truth is, they are
smothering in an atmosphere so laden
with carbOnfc acid gas and so exhaust
ed of its supply Of oxygen that candle
could hardly burn in il. Suppose an
