Sometimes the swarm will contain more than one queen and consequently will split up into several clusters. In such a case each cluster has to be "shaken" separately. Occasionally it becomes necessary to "shake" a swarm two or three times if the queen is not hived. It sometimes happens, too, that the queen will come out again if the hive is objectionable to her, and almost certainly so if she be a virgin. As a rule, though, the old queen comes out with the first swarm, but I have known cases in which swarming has been delayed, when as many as five queens, including the old one, have come out with the first swarm. In a very strong hive a virgin queen will sometimes come out with a first swarm, but in such cases the swarm, as a rule, is a very small one. The hive used for a swarm should be scrupulously clean and contain sufficient frames and combs for the requirements of the swarm. It is usual to place only one thin quilt over the frames for the first few days after a swarm has been given possession. Hives containing newly placed swarms are usually allowed to stay until the evening of the day before they are removed, but, of course, if the situation is an inconvenient one, or if the hive is liable to be a nuisance to the public, it should be taken away at once. If allowed to remain it must be sheltered from the rays of the sun or the heat will cause the bees again to issue forth. Should a swarm not be required by the bee-keeper he must return it to the hive whence it issued very early on the morning following the day of swarming. Each bee in a swarm usually carries sufficient food to meet its requirements for one day, so that should a bee-keeper receive a swarm from a distance he should feed it as soon as it arrives. All swarms should be fed if the natural supply of nectar be scanty. _Excessive Swarming._--Where bees are given to excessive swarming some bee-keepers trim one of the wings of the queen to hinder her flight,--a method also adopted to distinguish the ages of queens: the right wing of one year's queens being cut, and the left of those of the following year. Of course, the wings of a virgin queen should never be trimmed, for mating is thereby prevented. _Swarm Preventing._--The bee-keeper who works for surplus honey does all he can to prevent his bees from swarming, and thus increases both his stock of bees and supplies of honey.
