As detailed in the above article on "Driving" (page 226), there is a third hive made use of in this case, which has received the bees that returned home during the operation, and these are now added to whichever hive may most require them. Should too many have gone over with the swarm, this latter may be taken away and set in a cool airy place, while the old hive is carefully restored to its old stand, when the bees which were distractedly flitting in and out of the third hive will at once rush into it, and the impression made upon them by the occurrence will be such that they will now cling to it wherever it is placed. It must be forthwith removed to its intended permanent position, but if still short of bees this must be close at hand, so that if the forced swarm is kept where it is for a day or two a good number may desert to the old stock; its entrance should be closed until sunset as a precaution against robbers, but not so as to stop ventilation. The forced swarm, if not in their permanent hive, must now be treated as an ordinary transfer, and their fixed abode be brought in the evening to the old stand. Some additional covering may be needed at first, and in very cool weather the operation should not be attempted at all. There is no fear of all the bees deserting in the arrangement just suggested, and if inconvenient to complete the operation at once the swarm may be so left, even if there appears no need on account of the old stock. The process of driving is the only method of obtaining artificial swarms from cottage hives, except in such rare cases of good fortune as the one mentioned on page 236; but even with frame hives it is often practised for the sake of its rapidity. But with an experienced operator the same result can be achieved by simply taking out the frames one by one and jerking off the bees on to the sheet in front of the new permanent hive; that on which the queen is found will be inserted therein just as it is--queen, brood, and workers. If the swarm is being collected in a skep the queen must be taken with the fingers and deposited therein, while the bees from as many frames as are needful must be shaken in after her.
