50 A Modern Bee-Farm 
We have seen that eggs deposited in worker cells by such 
perfected queens, are fed to produce neuters, those in queen 
cell cups to result in fully developed virgin queens, and 
those in drone cells to become males. There is no altera- 
tion in the fertilising germs attached to the eggs intended 
to become workers or queens, but in the case of those in 
drone cells it is interesting to note that 
Workers have the means of removing the germs 
as when first deposited by the queen; thus normal males 
are the result of a very simple manipulation. I have 
repeatedly experienced this truth when preparing worker 
combs for queen-rearing purposes. The half of the comb 
given to the queenless bees, though containing only worker 
eggs, soon gave evidence of carrying workers, queens, and 
drones, at a date too early for any possible fertile worker 
eggs to result in drones. The other half of the same 
comb retained with the fertile queen had no drones in 
evidence. 
Drone Eggs exchanged for Worker Eggs. 
Since my own observations were carried out a German 
bee-keeper, named Dickel, has traversed similar ground, 
and on one occasion he removed a portion of the eggs from 
a drone comb, replacing them by worker eggs of another 
variety, when, instead of workers, the bees had so manipu- 
lated the inserted eggs that drones of the same variety (as 
the alien eggs) resulted. 
Fertilised Queens Deposit no Untainted Eggs. 
Repeatedly has it been stated that eggs laid in drone 
cells have no spermatozoa or germ attached, and therefore 
they must be unfertilised or non-impregnated. This is 
another of those amazing assumptions founded upon inde-
