Swarm Control. BT 
of a queen-excluder. (Fig. 8, (.) Place the supers directly above 
the queen-excluder and finally place the hive bodies recently occu- 
pied by the queen on top of the supers. Conditions now are similar 
to those present when a swarm is hived on frames containing none 
but emerging brood together with pollen and honey and the parent 
colony is placed on top of the supers (p. 26). Ten days later the 
queencells that have been built in the meantime usually should be 
destroyed, though this is not always necessary (p. 26). This plan is 
useful in extracted-honey production provided the honey-flow is not.

swarming during a prolonged honey-flow, since the colonies may later

brood-chamber from which she has been excluded at beginning of honey-flow. In the 
illustration it is assumed for convenience that the queen was confined to 2 when the 
excluder was inserted, which is here shown at the right as a separate hive supplied 
with a ripe queencell. The queen may have been confined to 1 instead, in which case 
she is transferred to 2, which is left on the old stand, and the queencell is given to 1, 
which is placed at one side. D, The brood-chamber containing the young queen (2)

again prepare to swarm. For a long honey-flow plan No. 3 may be 
preferable. 
This plan does not lend itself readily to comb-honey production, 
because bees usually do not begin work well in comb-honey supers 
when two hive bodies are used for the brood (fig. 9, 4), and the queen 
therefore may not abandon the lower hive body, as she does when 
extracting combs are used in the supers. For comb-honey produc- 
tion, however, a queen-excluder may be inserted between the two 
hive bodies 10 days previous to the time of putting on the comb- 
honey.supers, the queen being in this way excluded from one of them. 
(Fig. 9, B.) After 10 days, by removing and examining a single 
comb for eggs and larvae, it can be determined which hive body con- 
tains the queen. The queen should then be transferred to the hive
