ARTIFICIAL INCUBATION. %3 
look at the thermometer as quickly as possible, as it varies 
quickly. The drawer should be at 103 degrees, and if 
warmer than that leave the drawer out a little while 
until it cools down, always shutting it up first, in order 
to let the heat accumulate a moment or two before look- 
ing at the thermometer. Never try to cool it with cold 
water, for the heat is in the packing, and you can never 
tell what the effect will be for several hours. Should 
you add hot water, it will be from two to four hours be- 
fore the increased heat appears. It is due to this fact 
that the incubator is so reliable, as the heating and cool- 
ing is gradual. When the thermometer reaches 110° 
put in the eggs. The eggs will cool the drawer, but do 
not be alarmed. Let them remain for an hour or two, 
and if the temperature is then below 100°, add a kettle- 
ful of water (nearly a bucketful), which will return the 
heat to about 103° in an hour or two. Ifthe weather is 
moderate, once a day will only be necessary for adding 
water, but the better way to work the incubator is to 
divide the twenty-four hours into three periods of eight 
hours each, say 6 o’clock a.M., 2-P.M., and 10 P.M., when 
a gallon of water may be added at each time, and the 
eggs turned. This avoids late night work, and gives 
but little trouble. 
Be sure and practice with the incubator for three or 
four days before putting in the eggs, for by so doing you 
will know just how much water to use. 
The colder the weather the more hot water. All in- 
cubators do best in an even temperature. 
Keep a pan of water in the ventilator, changing it to 
fresh water daily. 
Keep the heat as near 103° as possible, and the last 
three days not over 102°. 
Take the drawer out in the morning and letit remain 
out for the eggs to cool down to 70°. Then turn the 
eggs half way round, and place the drawer back. Make
