SUCCESS IN POULTRY CULTURE 
that time, that the plan the machine was 
built on was one of fuel conservation, for 
I could not see any possible way for the 
heat to escape through all of that great 
thickness of sawdust. 
The next thing I did, being something 
of a mechanic, was to put a glass door on 
it; I thought I wanted to see what was 
going on in there during the hatch that I 
contemplated making. It had no door nor 
trays; but, instead of these, it had a big, 
heavy drawer that slid in and out with 
a heavy, awkward turning-rack in it; this 
turning-rack took up lots of room that I 
thought could just as well be used for 
eggs; so I discarded the old, heavy drawer 
and turning-rack and put four nice, light 
trays in their place. I put nice screen 
wire bottoms on the trays, and the four 
of them together held five hundred eggs. 
The new glass door and the nice, light 
trays made a great improvement on the 
old incubator, and I began to hear old 
Mr. Success knocking at my door; but 
alas! alas! alas! he got shy and foxy and 
disappeared before I had time to open 
the door and let him in. 
The incubator was now ready to heat
