geous not to attempt to use remedial measures until neces¬ 
sary. 
In the literature on swarm control, there are dozens of 
plans for accomplishing this end, and it is neither desirable 
nor necessary to give all of them or even all of the successful 
ones, for to attempt to do so would only be confusing. 
Unbalanced condition of swarming colonies. 
If the conditions which are found in natural swarming are 
examined, it will be recalled that, after the swarm issues, it 
receives no additional young bees for a period of at least 21 
days (unless they are given by the beekeeper in accordance 
with some of the plans previously outlined). If, as seems 
not unlikely, one of the most important factors in the cause 
of swarming is a preponderance of young bees, this condition 
is rectified for the swarm and the bees become “satisfied.” 
On the other hand, the parent colony rapidly increases the 
percentage of young bees (unless, again, they are removed 
by the beekeeper) and after-swarms are- not uncommon, 
unless the beekeeper manipulates to prevent them. It thus 
appears that the restoration of the balance of the colony is 
important in bringing it to a condition in which the swarm¬ 
ing tendency is lost and in which the storing instinct becomes 
dominant. 
Break in the emergence of brood. 
Whether this speculation is justified must be determined 
by future investigations, which are greatly needed. At any 
rate, and this is the point of importance to the beekeeper, 
those practical manipulations which are successful in the 
control of swarming, whether applied before or after queen 
cells are built, have for their result a single factor in common 
— a reduction or temporary cessation in the continuity of 
the daily emergence of brood. There have been numerous 
discussions of the principles of swarm control, for this is a 
problem which has attracted the attention of modern bee¬ 
keepers to a marked extent, but so far as the author is aware
