the manipulations without any thought on the part of the 
beekeeper. 
Mechanical appliances. 
Various mechanical contrivances have been advocated for 
separating the brood and the adult bees. After the queen 
has been placed in a new hive, the bees are trapped out and 
induced to enter the new hive on which has been placed the 
supers. There is no additional principle involved in these 
devices and they are serviceable only in changing the work 
that the beekeeper has to do. They often do not reduce 
the amount of time and labor needed. Among these devices 
may be mentioned the Hand bottom board (provided with 
levers so placed as to force the returning bees into the de¬ 
sired hive) and Dudley tubes for trapping out workers, all 
of which have been described in bee-journals. 
INCREASE 
It is assumed in the previous discussion that increase is 
not desired, and in comb-honey production in the North, 
where the swarming problem is most acute, increase during 
the honey-flow is usually too expensive to be justifiable. If 
the apiary has been reduced by winter losses or in some other 
way, or if an apiary is being built up, the beekeeper may 
prefer to sacrifice honey for bees. In connection with the 
operation of the various plans for controlling swarming, there 
will often be brood that can be used for increase. Another 
method is simply to divide colonies into two or more equal 
parts, preferably providing each queenless portion with a 
queen cell, or better still with a queen, as soon as possible. 
To obtain increase and to assist in swarm control without 
decreasing the crop too greatly, combs of brood with some 
adhering young bees may be removed and made into nuclei 
to be allowed to build up and to be augmented with frames 
of brood from other sources as they are available. 
In case the main honey-flow is in late summer ( e.g . buck-
