SUCCESS IN POULTRY CULTURE 
open end of heater pipe at left end of 
machine should be partly closed with a 
piece of tin. Do not close enough to make 
the lamp smoke. If lamp chimney is a 
conical one, it should extend as far up 
into heater as it will go; it should be large 
enough at top of mica to fill heater pipe. 
Turn the eggs before caring for the 
lamp. A little coal-oil or soot on your 
hands will injure them. 
Adjust regulator so 
_ that damper will not rise 
until temperature is 102° F., then adjust 
it so that damper will just start to rise. 
Run the machine for a day or two before 
putting in the eggs and watch it closely, 
and if temperature does not rise above 
103° nor fall below 102°, your regulator 
is properly adusted, and your machine is 
ready for the eggs. Do not turn lamp 
high enough so that damper will rise over 
¥,”; to do so is a waste of oil. Hold tem- 
perature at 102° to 103° the first week, 
and then at 103° for the remainder of the 
time. Regulator will have to be adjusted 
from time to time on account of increas- 
ing heat given off by the eggs as hatch 
proceeds.
