Turning now to the particular insect with which we intend to interest ourselves, we observe that every hive or bee colony comprises in summer three distinct classes of bees, each class having functions peculiar to itself, and essential to the maintenance and well-being of the community. As each bee knows its own proper duties, they all work harmoniously and zealously together for the common weal. Certain apparent exceptions to the good-fellowship of the bees will be hereafter noticed, but these arise out of essential conditions in the social economy of the bee community. That _honey bees_ should live in society, as they do in hives, is absolutely needful. A bee in an isolated condition is a very helpless delicate little creature, soon susceptible of cold, and paralysed thereby unless able to join her companions before night comes on. By congregating in large numbers bees maintain warmth, whatever the external temperature may be. The three classes of bees are--the queen bee, or perfect female; the working bees, or undeveloped females; and the drones, or male bees. § II. THE QUEEN, appropriately styled, by German bee-keepers, the mother bee, is the only perfectly developed female among the whole population of each separate colony. Thus her majesty indisputably sways her sceptre by a divine right, because she lives and reigns in the hearts of loving children and subjects. The queen may very readily be distinguished from the rest of the bees by the greater length of her body and the comparative shortness of her wings; her legs are longer, and are not furnished with either brushes or baskets as those of the working bee, for, being constantly fed by the latter, she does not need these implements; the upper surface of her body is of a brighter black than the other bees', whilst her colour underneath is a yellowish brown;[5] her wings, which do not extend more than half the length of her body, are sinewy and strong; her long abdomen tapers nearly to a point; her head is rounder, her tongue more slender, and much shorter, than that of the working bee, and her sting is curved. Her movements in the hive are measured and majestic, though when out of her proper sphere, as at swarming time, she is distinguished, on the contrary, by the rapidity of her steps. She has a peculiar scent, which is so attractive to workers, that Mr. Mahan, of Philadelphia, states he has several times had them alight upon his fingers, a mile away from his apiary, after he had been handling the royal mother. [Footnote 5: Yellow Italian queens form an exception in point of colour. See Plate I. Fig. I.]
