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.

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-
