One great advantage of this arrangement lies in 
this — that, at the expiration of the ten or eleven days 
after the first swarming, the Ligurian stock removed 
to Stand] IV. will have finished queen -cells, only one 
of which will be required for itself ; a surplus one 
may then be cut out and given to the black stock, 
which has just* lost its queen, and which will, in 
* It is wise, unless we take the precaution ot using a “ Doolittle 
Cage” (which see), to delay inserting the queen-cell until the day following 
the removal of the swarm, or the queen-cell may be torn open.
