Incubation

A short pipe, with a faucet attached, should be screwed into the spigot 

 opening of the barrel. The barrel may then be rolled into place, and 

 the faucet connected with 

 the pipe leading into the 

 cellar by means of a short 

 rubber hose. 



The oil faucet in the 

 cellar should be placed in 

 a convenient location, pref- 

 erably in a corner at some 

 distance from the incu- 

 bators. A pan should be 

 placed underneath the 

 faucet in order to catch 

 the dripping and to prevent 

 waste of the oil. A small table on which to place the lamps should be 

 provided near the faucet. 



THE LAMP 



The results of incubation will depend largely on the care given to the 

 lamp, for which one person should be responsible. No one else should 

 raise or lower the flame, or interfere with the lamp in any way except 



in order to prevent an accident. 

 The lamp should be filled, the 

 wick trimmed, and the burner 

 cleaned, once each day. 



Filling the lamp.- — A regular 

 hour should be assigned for filling 

 the lamp, preferably in the morn- 

 ing and never at night, and all 

 other work should be arranged to 

 conform to this time ; otherwise 

 the lamp may be neglected and 

 serious results may follow. The 

 best time in the morning for this 

 work is immediately after the eggs 

 have been cared for. If the lamp 

 is handled before the eggs are 

 turned, the hands may become 

 oily and thus the eggs may be 

 soiled. Incubator lamps should be filled to within one half inch of the 

 top, and never completely full. Only the best grade of oil should
