much faith in the regulator, relying upon it too implic- 

 itly, and often fail in consequence. Other incubators 

 regulate the heat very well, but cannot do away with 

 the work of watching the flame of the lamps. The 

 flame must be regulated according to the temperature 

 of the outside atmosphere. To be successful the oper- 

 ator must determine that he will do the work himself, 

 and he must watch, the incubator, whether it regulates 

 or not. He who attempts to raise chickens artificially 

 by using a self -regulating incubator without expecting 

 to do anything except to trust to the machine, will 

 always be of the opinion that incubators are humbugs. 

 It means work and attention every time, but it is work 

 that pays if well bestowed. 



In Harnmonton we do not use any self-regulators at 

 all. Our incubators are simply tanks surrounded by 

 sawdust, made by placing the sawdust between an inner 

 and larger box, the tank being in the top of the inner 

 box. The tank for a hundred- egg incubator is 15x30 

 inches, 7 inches deep, and rests on strips around the 

 edges, with half-inch rods under it every six inches to 

 support the weight of water. The egg-drawer is 15x36 

 inches, 6 inches fitting in the space at the opening when 

 the drawer is shut. This space in the front of the egg- 

 drawer is also boxed off and filled with sawdust. The 

 ventilator is six inches deep, the egg-drawer three inches 

 deep inside. Two tin tubes, one inch in diameter, are 

 placed at the bottom of the ventilator to admit dir. 

 Four inches of sawdust surround the inner box. A tube 

 on top of the tank, which passes through the boxes, 

 allows water to be poured in, while a spigot in front, 

 over the egg-drawer, permits it to be drawn off. This 

 tank is filled with boiling water. The eggs are hatched 

 at 103 degrees. The heat is regulated by drawing off a 

 bucket of water night and morning. The eggs are 

 turned twice a day. Moisture is supplied with boxes of
