much faith in the regulator, relying upon it too implice 
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 cpinion that incubators are humbugs. 
It means work and attention every time, but it is work 
that pays if well bestowed. 
In Hammonton we do not use any self-regulators at 
all, Our incubators are simply tanks surrounded by 
cawdust, 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 air. 
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 twicea day. Moisture is supplied with boxes of
