When driving is the method resorted to, it becomes absolutely essential, in forcing a swarm, that the queen should go with the new colony; but on the other hand it is not in this case the object to drive _all_ the bees from the parent stock, but to leave, say, a quarter to preserve warmth for the brood and to raise a new queen. If therefore the queen is not observed in the ascent of the bees after the drumming, those in the swarm must be turned and shaken over in the skep in order to find her (they will not attempt to fly, but only crawl). An inexperienced eye may still fail to detect her, and in that case it will be best to set both hives upon stands for a short time--the new one on the old stand and the old on some other--when within half an hour the one which is fairly quiet may be judged to be possessed of the royal presence. Should this be the old hive it must be again drummed, or the swarm may be returned to it and the operation renewed on a following day. It is, however, only with skep hives that any difficulty of this kind need be apprehended--there is always the power of capturing and transferring the queen from movable frames. When at last she is in the desired hive the swarm is secured, and the after measures depend on the number of bees that have accompanied her. If the stock retains one-half it may be moved to a new position and the swarm take its place upon the old stand. Whichever occupies this latter post will detach largely from the strength of the other, so that the reduction undergone by the parent stock will not be more than it will probably be able to sustain.
