 of the machine by means of both an incubator 

 thermometer and a registering thermometer. 

 These records will sometimes be of value in reg-

BBOODEES 



If artificial incubation is employed, some 

 provision must be made for the care of the 

 little chickens as soon as they leave the incuba- 

 tor. Various kinds of machines have been de- 

 vised for this purpose, which vary considerably 

 in regard to efficiency, but some kind of an 

 artificial brooder must be provided. From the 

 great variety of brooders on the market the 

 farmer or poultryman has an opportunity to make 

 a selection according to his wants and best judg- 

 ment. Brooders vary greatly in size, as some of 

 the smaller ones accommodate no more than fifty 

 chickens, while the larger ones are devised to 

 furnish accommodations for many hundreds of 

 young fowls. For convenience, we may separate 

 the various kinds of brooders into two classes. 

 These classes represent two entirely different 

 systems of furnishing heat and providing for 

 the comforts of the little chickens. One class 

 supplies heat by means of hot water pipes. See
