During the operation a sharp look out should be kept for the queens on the brood combs, and if one of them should be preferred for heading the new colony she should be caged by herself on a comb in the manner described above to prevent any hostile workers from attacking her. The other queen must then be found and removed, and the bee-keeper must remember to liberate the caged queen on the following day. If left to themselves, however, the workers soon learn to recognise one of the queens as their mother, so that the trouble of finding and caging the queen is not really necessary in uniting, but it is an additional safeguard which the practised bee-keeper is glad to be able to take advantage of. It was stated just now that the presence of _worker_-brood in the hive was sufficient evidence of the presence of a good queen. In some cases where there is a bad queen or no queen at all, _drone_-brood may be found in the hive. Usually the bees build a special comb with cells of a larger pattern for raising drone-brood in, but a bad queen will often lay drone eggs in worker-cells. In either case drone-brood may be known from worker-brood by its raised convex cappings, the capping over the worker-brood being almost flat. The best thing to do with a drone-raising colony is to unite it to another good colony without delay in the manner described above. Having settled the question of strength, the next thing to see about will be the food supply. If each hive does not possess the minimum weight of 20 lb. of stored honey, combs containing food must be given from another hive that can spare them, or syrup must be supplied through the feeder. Syrup for winter use must be made thicker than that used for stimulating in the summer, 10 lbs. of cane sugar being dissolved in only 5 pints of water. The syrup must be given quickly (5 or 6 lb. every day), otherwise much of it may be used for raising brood. For this purpose special rapid feeders, made to hold 6 lb. of syrup, are made. If the stock-box contains more than 30 lb. of honey, we may take and extract the surplus from the outside combs, or one of these combs might with advantage be given to a colony that stands in need of it. Bee-keepers who live in the heather districts of Scotland and the north of England will now be reaping the late honey harvest that this plant affords, getting their supers filled with the delicious heather-honey, which is so highly esteemed for its fine flavour. Persons keeping a few colonies a little distance from the moors find it worth their while to send their bees there while the heather is in bloom. Heather-honey has a deep colour. It is so thick that it is extremely difficult to remove it from the comb by means of the honey extractor. It should therefore be stored in sections, as these do not require extracting. Sections of heather-honey should fetch about threepence more than ordinary sections.
