tack a strip of sheet-iron around top of 
heater wide enough to come up within 
1%” of top of heater pipe F. This piece 
of sheet-iron is not shown in cuts. Put a 
little of the cement around lower end of F. 
Now fill in all around between outer and 
inner case of incubator with dry sawdust. 
Fill in on top of inner case to top of cor- 
ner posts with same. If dry sawdust is 
not to be had, dry chaff will do, but it is 
not so good. 
Now make a top out of ceiling lumber 
same as used on sides, just large enough 
to fit inside of siding and rest on corner 
posts. Fasten it together by nailing it 
to two cross-pieces placed on the under 
side 2” from each end. Now make four 
legs out of 1x4 32” long; put on two at 
each end flush with front and back as 
shown in Figs. 1, 2 and 3. Fasten them 
with screws. The swinging lamp bracket 
is so plain that it needs no description. 
It is swung to leg of machine with 
one T hinge the height to suit the 
lamp you intend to use.

out of good soft pine or
