PROPAGATION 
dling your incubator, and you should 
observe carefully every cause and effect 
connected with it. 
For myself, I use a thermometer with 
adjustable legs. It stands on the bottom 
of the tray, adjusted so that the bulb is 
on a level with the top of the eggs, with 
the tube slanting upward. An egg or two 
is left out so that there is space all around 
the bulb of the thermometer. This ar- 
rangement causes the thermometer to reg- 
ister more accurately, at all times, the 
temperature of the machine than when it 
is placed on top of the eggs. The ther- 
~ mometer should not be moved about from 
place to place in the incubator, but should 
remain about in the same place during 
the whole period of incubation. 
The management of the incubator 
should be left to one individual of the 
family; for if two undertake it at the 
same time, they are apt to confuse one 
another and the result will not be so good. 
The brooder should, 
like the incubator, be run 
according to the instruc- 
tions of the designer or manufacturer. 
The brooder must be kept scrupulously
