contain at least a moderate amount of mois- 

 ture. The amount of moisture in the atmos- 

 phere should control, to some extent, the venti- 

 lation of the incubator. It is desirable that a 

 considerable proportion of the moisture of the 

 egg be evaporated during the process of incuba- 

 tion. If the air is very dry a little ventilation 

 will be sufficient to secure the desired evapora- 

 tion, while a moist atmosphere would require 

 much more ventilation to secure the same result. 

 The moist air of a wet cellar, which contains 

 decaying fruit and vegetables, is not suited to 

 incubation. 



Whenever kerosene oil lamps are kept contin- 

 ually burning for weeks at a time, as they are 

 in incubators, there is some danger from fire. 

 It is true that the modern incubator lamps are 

 well adapted to the purpose, but the element of 

 danger from fire cannot be said to be wholly 

 eliminated so long as these lamps are permitted 

 to burn in wooden buildings without the watch- 

 fulness of an attendant. 



The convenience of an incubator room is prob- 

 ably one of the least of the essentials, yet it is 

 of so much importance that it should not be 

 wholly overlooked. Everything considered, prob-

 the most desirable location for an incubator on 

 the farm. Many incubator rooms have been con-
