above one hundred and three degrees. If there must 

 be a variation, ninety-five degrees is far better than one 

 hundred and five. If the air in the room is constantly 

 warm and dry, place a second pan of lukewarm water 

 in the machine at the end of the second w r eek. If the 

 room is in a cellar and moisture shows on the windows, 

 one pan of water under the eggs is quite sufficient. 



"When the eggs begin to hatch don't open the door 

 for love or money. Have the thermometer fastened so 

 the chicks cannot knock it over and see that the tem- 

 perature does not rise above one hundred and three. 

 Don't remove the chicks from the chamber until they

have been hatched at least twenty hours ; then quickly 

 place them in a brooder heated to one hundred. When 

 you buy an incubator see that the egg tray fits the 

 chamber, so that newly hatched chicks cannot possibly 

 fall over its edges into the moisture pans below." 



How to Make an Incubator Scores of machines 

 have been made according to the following description, 

 and good success in hatching has resulted. This incu- 

 bator requires closer or more frequent attention than 

 do machines with a more elaborate system of heat 

 regulation, but with care and experience first-rate 

 hatches may be obtained.
