last them until they gather fresh honey rapidly enough to supply their daily needs. The presence of an abundance gives the bees courage. They do not fear to draw upon their stores to supply the young that are fast developing. The combs filled with honey part with their heat only slowly when the outside temperature falls, and there is thus less danger of a check in the development of the brood through too low temperature in the hive. [Illustration: Fig. 18.--Box hive prepared for transportation. (Original.)] If the surfaces of the combs, the frames, or the inner walls of the hive are spotted with a brown, crumbly looking substance it is an evidence that the bees have bad diarrhea during the winter or spring, and if they have been badly affected not only will the combs and the whole interior of the hive be soiled, the former perhaps so as to be rendered almost worthless, but the bees will lack vitality, and will soon dwindle in numbers, not being able to survive the first arduous labors of the opening of the season. It is not always easy to determine whether a stock in a box hive is affected with foul brood or not, for the odor of decaying brood is not of itself sufficient to warrant such a conclusion, although it is well to reject any hive having any putrid odor about it. The natural odor of the hive, produced as it is largely by honey, wax, pollen, and propolis, is not unpleasant to most people, so that the presence of any disagreeable odor should arouse suspicion. If larvæ that have turned black are seen in the cells, and the capping of the sealed brood is sunken and in some instances perforated, showing brown and ropy contents in the bottoms of the cells, and the putrid odor is present, the existence of foul brood (_Bacillus alvei_ Cheshire) is pretty certain. This is a scourge much to be dreaded. Not only should no hives or colonies be purchased from the same apiary, but none in the vicinity of an apiary so affected.
