the lever to work freely in. This is to 
prevent too much air escaping from incu- 
bator at this point. These pieces are not 
shown in cut. A small piece of glass 
should be placed over holes in door on the 
inside. It can be fastened on with large- 
headed tacks. 
The heater pipe F should have the 
corrugations straightened out of its lower 
end so that lamp chimney will fit. You can 
use conductor pipe that has no corruga- 
tions, but I think the corrugated is the best. 
First level the incu- 
bator. Set two shallow 
pans of water over the 
holes in the bottom of the 
incubator, one under each tray. These 
pans should be 10” in diameter and set on 
four small blocks 14” thick. 
These blocks are for the purpose of 
holding the pans up so air can pass under 
them and out through the holes in the 
bottom of the machine. This is important, 
for if the holes are closed, by setting the 
pans flat down over them, the incubator 
would not get proper ventilation. If other 
moisture-pans are needed, they can be set 
flat down on the bottom of the incubator.
