324 A Modern Bee-Farm 
they have observed the temperature surrounding a queen 
cell with the bees always packed closely around it, thus 
giving greater or at least more certain heat than is required 
for the rest of the hive? If so, they will be surprised to 
find how much lower is the temperature surrounding the 
cells where no bees can cluster upon them, and where they 
do not even care to crowd upon the metal at each side 
of the little cages so many apiarists use in hanging-frames.* 
All animal life is produced by heat, varying according as 
the nature of the creature may require, and for our purpose 
the lamp nursery supplies the correct and even temperature 
desired. 
The illustration of the Author’s nursery shows the 
Opening at the side, with a double casing on all other 
sides, with about one inch between the inner and outer 
walls. The whole of this compartment is enclosed by 
wood with a closely-fitting door which closes the said 
open side. The inside is fitted with skeleton framework, 
wherein slide several drawers, each: covered on the underside 
with woven wire. The same arrangement will also take 
whole frames of comb, but I prefer to have the cells built 
that they may be removed ‘singly and so placed in the 
trays. A thermometer is fixed in a vertical position at one 
side, thus the temperature can be noted at a glance without 
exposing the cells. With my arrangement, however, the 
heat is always given from above, and even after examination 
of the interior there is not the same loss of heat as with the 
nurseries hitherto used where the whole top is opened, as 
such have no large body of heat just where most needed for 
the immediate restoration of the correct temperature. 
Under the hollow heating cylinder H C is placed the 
Jamp, which has a wick of such a size that it cannot very 
* Excluder zinc used to separate cells in a queenless colony 
largely overcomes this objection.
