"The bee hive derives its name _alvus_, which is the same as our word for belly, from the fact that it holds food, that is to say, honey; and it is on this analogy that hives are usually shaped to imitate the form of the belly, small in the waist and bulging out below. When the hives are made of wicker work they should be coated evenly within and without with ox dung[211] so that the bees may not be driven away by the roughness of their roof. The hives should be so ordered under the shelter of a wall that they may not be disturbed nor touch one another when arranged in ranks, for it is the practice to place hives in two and some times three separated ranks, but the opinion is that it is better to reduce the ranks to two than to increase them to four. In the middle of the hive small openings are made on the right and the left to serve as entrances for the bees, and on top is placed a practicable cover, which may be removed to give access to the honey comb. This is best when made of bark, and worst of pottery, because that is strongly affected both by the cold of winter and the heat of summer. In spring and summer the bee keeper should inspect each hive at least three times a month, fumigating them lightly, cleaning and throwing out dirt and worms. At the same time he should take precautions to keep down the number of princes, for they keep the bees from work by stirring up sedition. There are said to be three kinds of royalties among the bees: the black, the red and the mottled, or, as Menecrates writes, two: the black and the mottled: and as the latter is the better it behooves the bee keeper, when he finds both kinds in a hive, to kill the black one, as he is forever playing politics[212] against the other king, whereby the hive must suffer, for inevitably one of the kings will flee or be driven out, in either case taking his party with him. "Of working bees the small round mottled variety is considered the best. The drone, or, as some call him, the thief,[213] is black with a large belly. The wasp, which has some resemblance to a bee, is not, however, a fellow labourer, but attacks the bees with his sting, wherefore the bees keep him at a distance. "Bees are themselves distinguished as wild and tame. I call those wild which feed in the forests, and those tame which feed in cultivated places. The forest bees are smaller in size and hairy but better workmen. "In buying bees it behooves the purchaser to see whether they are well or ailing. The signs of health are a thick swarm, well groomed appearance and a hive being filled in a workmanlike manner. The signs of lack of condition on the other hand are a hairy and bristling appearance and a dusty coat, unless this last is caused by a pressure of work, for under such circumstances they often wear themselves down and become thin.
