=Re-queening the Hive.=--As already stated, the method of working the hive with standard frames as a super necessitates re-queening every two years. There are several ways of doing this. One is to find the old queen and kill her, and allow the bees to install one of the young queens. This method, however, has many disadvantages. First of all, there is the disturbance to the hive in the search for the queen; secondly, if the queen be found and killed, there is a loss of nearly three weeks in the height of summer when no eggs are laid in the hive. Another method is to allow the hive to swarm and to return the swarm to its hive after destroying the queen. But this plan, too, has the disadvantage of checking the supply of eggs. The best method for all practical purposes is to re-queen after the honey-flow, either with a home-reared queen or one purchased from a reliable breeder. The old queen, together with any queen cells in the combs, must be removed three or four days before the new queen is introduced. The easiest way to accomplish the introduction is by means of a _queen-cage_. These are usually made of wood with three compartments, in the inner two of which the queen is imprisoned. The other is filled with soft candy. This cage is placed over the frames in the hive and the queen is liberated by the bees eating a way through the candy. By the time this is accomplished the queen will have acquired the scent of the hive and will be accepted as ruler by the community. The hive should not be disturbed for at least four days after the introduction of the new queen.

The old method of dealing with this matter was the drastic and wasteful one of putting the hive over the sulphur pit and wiping out the bees. The more economical, as well as humane, method of driving is now generally practised by the commercial bee-keeper. Driving is often accomplished immediately after the clover has finished flowering, and the bees sold to the bee-keepers in the heather districts, who are often glad to increase their stocks in readiness for the heather honey harvest. In other cases the driven bees are used to strengthen weak hives. In any case driving must be done before the autumn unless the bee-keeper is prepared to give the bees drawn-out combs and food to fill them with in preparation for the winter. When driving is to be put into operation it is always advisable to remove the hive that is to be driven well away from the other hives, for the operator is far more liable to be stung by the bees from them than by those to be driven. An empty hive should be placed in the position occupied by the removed one: this will serve to attract any stragglers and prevent their flying away.
