§ V. UNITING COLONIES.
A weak colony may frequently with advantage be added to another, or three may be made into two. And not only may this be done with new swarms, but in autumn, when there is no brood in the combs, it may be carried out also with stocks, the combs that are extracted being taken care of for use when required. After working hours is the best time for this operation. It is not, however, altogether a simple one, as strange bees will not intermix unless measures are taken to overcome their natural hostility to each other. Whatever be the number of hives in an apiary, the bees of each know the smell of their own companions. A single bee that enters the wrong hive will be stung to death, unless possessed of a good booty wherewith to disarm animosity. Similarly on the admixture of entire colonies, if one has some distinct ground of advantage over the other, there must be a method hit upon to deprive it of this or else to purchase its goodwill, for otherwise there will ensue a ferocious and disastrous slaughter. If both are alike frightened all will go well, and the same if both are upon the wing in search of a home; but quite otherwise if one is self-possessed and active in its own abode, while the others are frightened strangers and gorged, and it may be still further demoralised by having lived under an unfertile queen, or with none at all. But if both are cowed alike by a good drumming on the hives, they may be sprinkled so as to possess the same scent, and then taken to a third position and shaken out on to a sheet together, when they will enter the offered hive in harmony. If each colony has a queen, one of them may be searched for and removed.
A slight variation upon this method consists in driving the bees of the one hive (see last section) straightway into the other, having first terrified the bees of the latter by drumming until by their changed note they may be concluded to be thoroughly subdued, and as a consequence gorged with honey; then, before their equanimity is recovered, the others must be joined to them. A third plan is the one usually practised with the Stewarton hive ([page 151]), and which can be imitated with other hives, by means of ekes or nadirs; this is usually carried out in the evening, when the quietude appears efficacious in settling all differences without the necessity of any other precautions. A fourth is as follows: At dusk, dislodge the bees on to a cloth, sprinkle them with sweet syrup scented with essence of peppermint (as a means of bribing their new hosts to receive them), and place the hive to which it is intended to join them over the mass; they will gradually ascend into the hive placed for them, and early next morning the hive, with its slender stock thus augmented, may be removed to its stand. Should the operator not have been successful in gaining possession of the queen, he may leave it to the bees themselves to decide which queen they will have.
Many persons feel more secure from stinging if they first stupefy the bees by fumigation. These should proceed as follows: Having used the fumigator upon the bees in one hive, as described under that article ([page 207]), place a sheet on the ground and spread the bees on it; then, with a feather, sort them over, in order to pick out the queen. As soon as she is found, pour the rest of the lethargic swarm from off the sheet back into the inverted hive again. The stupefied bees must now be sprinkled freely with a syrup made of honey and water, or sugar and ale boiled together. Some apiarians recommend a few drops of peppermint to be mixed with the syrup, in order to drown the peculiar odour which is special to each hive of bees; this is more necessary when both hives are fumigated, and whilst under the influence of smoke are well mixed together upon the sheet or board. Such course can be adopted if preferred, and no further instructions will be needed than what are here given; but we will suppose as before that only one is thus operated upon. The hive containing the non-stupefied bees must now be placed on the top of the inverted one, just as the hive was from which the bees in the latter have come. A wet cloth must be fastened round the two hives, so as to prevent any of the bees from escaping. The hives in this position must be placed where they are not likely to be knocked down or meddled with. The fresh bees in the upper hive, attracted by the scent of the bees besmeared with honey, go down and commence licking off the sweets from the sleepy ones. The latter gradually revive, when all get mingled together and ascend in company to the upper hive, where they live as if they had not been separate families. The two hives should be left undisturbed for twenty-four hours, when the upper hive may be removed and placed immediately on the spot from whence it was brought.
The removed queen should be kept alive and fed as long as she will live, in case any harm should befall the sovereign of the other community. If three hives are to be incorporated in two, the only difference will be that the stupefied colony upon the sheet is divided into two empty skeps, the one being covered securely over till the other is adjusted.
