An egg-drawer two feet wide and three feet long will 
hold one hundred and fifty eggs with an egg-turner. A 
drawer three feet wide and four feet long holds three 
hundred eggs. Only one drawer can be used to an in- 
cubator. 
BROODERS. 
The principal conditions necessary in a brooder are 
plenty of fresh air and_sufficient heat to prevent the 
chicks from crowding. We have a building here, now 
in operation, divided into ten apartments, each apartment 
being five by seven feet and accommodating one hun- 
dred chicks. The building is filty feet long and ten feet 
wide, and a passage way running its whole length, and 
taking up three feet of the ten, leaving the spaces for 
the chicks seven feet. ‘The yards are sixteen feet long 
and five feet wide. The chicks are all brooded with a 
stove. To describe how it is done, we will explain that 
Fig. 46 is a box six inches deep, three feet wide, and fifty 
feet long. Two-inch iron pipes are arranged as shown 
in the illustration, the top of the box being removed to 
show the interior. The hot water may be supplied by 
an ordinary stove ‘‘ water back,” or by a coil of pipe in 
astove. ‘This is heated by a piece of pipe one inch in 
diameter, coiled in a stove, holes being cut in the stove for 
the purpose of admitting pipes. The hot water flows out 
and the cold water flows in. The floor of the box is made 
close, with tongued and grooved boards. The cold air 
enters through tubes reaching to the outside of the build- 
ing. It is heated by coming in contact with the pipes, 
and enters into the tubes on the top of the floor, which 
are two anda half inches high. Over these tubes are
