well have a flame which will overheat the chamber; the 
latter being about 18in. by 12in. by gin. The boiler 
contains between the walls about six gallons of water, so 
that when the right temperature is once secured it does not 
vary one degree in twelve hours. The lamp is trimmed 
once in 24 hours, regularly every evening, so that there is 
no chance of the flame dropping during the night, when no 
attention is needed. 
A sponge or cloth saturated with water,.or a shallow 
tray holding a small quantity, should be placed in the 
chamber to induce the necessary moisture. 
Though the time of hatching is delayed under a 
temperature of 90°, I find queens will come out with 
perfect wings, but I prefer it regulated nearly as possible 
at 95°, so that in case of any accident there may be no 
danger resulting through slight variations. When properly 
managed, no intelligent apiarist will deny that the incubator 
or lamp nursery gives a more even temperature than can 
be obtained in the hive. That of the former is almost 
perfect, while the hive varies considerably, having its 
entrance always open to. the outer air; and when a cold 
snap occurs, the bees shrink away from the caged cells. 
The cells are not placed in the nursery until they are 
capped ; but I can take a céll before it is capped (when of 
course it is not closed at all), and relying on the perfect 
temperature maintained, can see the process of development 
gradually evolved day by day, until the young queen is 
matured ; the delicate tracing of the wings being unfolded 
from white pap-like balls almost at the last day.
