as uniform as possible. Thus a cellar, an un- 

 used room, or a stable are all suitable. Where 

 the raising of poultry is done on a large scale 

 special cellars are built. Good ventilation is 

 necessary ; the place should never be damp, 

 nor should vegetables in a state of putrefac- 

 tion be kept in it. Nevertheless, do not 

 choose a cellar exposed to drafts, for nothing- 

 is more injurious when the eggs are turned 

 over. The temperature should never go 

 below 100° F., nor above 105°. If the tem- 

 perature falls below 100° the eggs will be 

 chilled when turned, and if remox-ed into 

 another room they will be exposed to a 

 current of air. In no case should the incu- 

 bator be placed either near a stove or near 

 an open window. 



When the incubator comes from the deal- 

 ers and is unpacked and fixed according to 

 the directions sent with it, the lamp being 

 fixed and the regulator set up, the next thing 

 to be done is to place it in a perfectly hori- 

 zontal position, and then to study and com- 

 prehend its arrangement and subdivisions. If ventilation, which in\'ol\-es the questif)n of life
