ACCESSORIES AND APPLIANCES 
The lamp should now be lit and the 
temperature in the machine run up to 
103° F. and run several days at that tem- 
perature, or until it is running steadily, 
without much variation; the eggs should 
not be put in until after this preliminary 
run has been made, to see that everything 
works smoothly and all right. During this 
preliminary run the bulb of the thermom- 
eter should be as high from the bottom of 
the tray as the top of the eggs that you 
intend to hatch in the machine will be. 
The bulb should not come in contact 
with anything, but should have a clear 
air space all around it. 
I use a thermometer 
with adjustable legs that 
set on the bottom of the 
trays, but for the novice, or a person 
using this incubator for the first time, I 
would recommend a thermometer without 
legs, that will lie flat down on top of the 
eggs. After the eggs are put in, lay your 
thermometer flat down on top of them 
about 6” back from the front end of the 
tray. Put the thermometer in the tray 
nearest to the lamp and near the side of 
the tray farthest from the lamp. Keep
