11. The thieves and the drones do not work, but only injure the other bees, and when taken they are killed by the useful bees. Many of their rulers are also frequently killed, and especially the bad ones, in order that the swarm may not be dispersed by their numbers. They are the more disposed to kill them when the swarm is not fruitful, and no casts are formed. At such times they destroy the royal cells, if any have been prepared, for they are the leaders of the swarm. They destroy also those of the drones, if honey is scarce, or the swarm is short of honey. They fight boldly for their honey with those that would take it from them, and drive out any drones that may be in the hive, and are often seen sitting upon the hives.

12. The small bees fight eagerly with the long kind, and endeavour to drive them from their hives: and if they prevail, it seems to be a sign of a very strong swarm; but if the others conquer, when left alone, they are idle, and do nothing that comes to good, but perish in the course of the autumn. Whenever the useful bees kill any of them, they endeavour to do so outside of the hive; and if any of them die in the hive, they carry them out. Those which are called thieves injure their own combs, and if they can do it in secret, they will enter those of other bees, but if discovered they are killed. It is, however, difficult to enter unperceived, for there are guards placed at each entrance; and if one contrives to enter unnoticed, he is unable to fly from repletion, and is rolled out before the whole swarm; so that it is difficult to escape.

13. The kings themselves are never seen out of the hives, except with a young swarm, and in young swarms all the rest appear to be collected round him. When a swarm is about to separate, a peculiar and singular noise is made for some days, and for two or three days beforehand a few bees are seen flying round the hive; and if the king is among them he is not seen, for it is not easy to see him. And when they are collected, all the rest fly away and separate themselves with their respective kings: and if a few of them happen to be near at hand, they join themselves with one of the numerous swarms. And if the king that they have left follows them, they kill him. This is the manner of their leaving the hive, and of swarming.

14. They all have their proper work to perform. Some bring flowers, others water, and others polish and erect the cells. Water is brought when they are rearing their young. None of them ever settle upon flesh, nor will they eat anything seasoned. They have no particular time for commencing work, but when they are properly supplied, and in good health, they are particularly diligent during the summer. When the day is fine they work without ceasing, and as soon as the young bees are three days old, they set to work, if properly fed. And when the swarm settles some depart for food, and afterwards return. In healthy swarms the progeny of the bees only cease from reproduction[228] for about forty days after the winter solstice. As soon as the young bees are grown, they offer them food, and smear the cells with it, and as soon as they are strong enough, the young bees rupture the covering of the cell, and so escape.

15. The good kinds of bees destroy any creatures that are produced in their hives and destroy the combs; but the other kinds from their inferiority overlook the destruction of their work. When the dealers in honey take the combs, they leave the bees some food for the winter. If sufficient is left, the swarm is preserved; but if not, they either die in the winter, or, if the weather continues fine, desert the hive. They eat honey both in summer and in winter. They also lay up another kind of food, which is as hard as wax, which some persons call sandarache.

16. Wasps are very injurious to them, and so is the bird called titmouse, and the swallow, and merops. The frogs also in marshes destroy them when they come for water, for which reason bee-fanciers destroy the frogs in those marshes where the bees come for water. They also destroy wasps' nests, and the nest of the swallow and merops, if near the swarms of bees. They avoid no animal, except those of their own kind. They fight among themselves, and with the wasps. When at a distance from their hives they will neither injure each other, nor any other creature; but when near at home they will destroy everything that they can conquer.

17. When they have stung anything they perish, for they cannot withdraw their sting from the wound without tearing their own entrails; but they are frequently saved, if the person stung will take care to press the sting from the wound: but when its sting is lost, the bee must perish. They will kill even large animals with their stings, and a horse has been known to perish, if attacked by bees. The rulers are the least cruel and stinging.

18. If any bees die in the hive, they carry them out; and in other respects the bee is a very clean creature. For this reason they also eject their excrement when in flight, for the smell is bad. It has been already observed that they dislike bad smells and the scent of unguents, and that they sting persons who use such things. They also die from other causes, as when the rulers in the hive are in great numbers, and each leads out a portion of the swarm. The toad also destroys bees, for it blows into the entrance of the hive, and watches for and destroys them as they fly out. The bees cannot inflict any injury upon it, but their keepers destroy it.

19. Some bee-keepers say that the kind of bee which makes an inferior and rough comb is the young of the others, and that it is the result of imperfect skill. They are young when a year old; young bees do not sting so severely as old bees; for this reason the swarms are carried to the apiaries, for they are those of young bees. When honey is short they eject the drones, and put figs and other sweet things near them. The elder bees work in the hives, and become hairy from remaining within. The younger ones go out in the fields, and are smoother: and they kill the drones when they have no longer any room for them, for they are placed in a recess of the hive. When a swarm has been weak, strange bees have been known to come and fight with them, and take away their honey; and when the bee-keeper killed them the others came out and defended themselves, and would not injure the man.

20. Other diseases, and especially one called clerus, frequently attack strong swarms. In this disease small worms are produced on the floor of the hive, and as these increase, the whole swarm is held, as it were, in a spider's web, and the combs decay. There is another disease, which is like a wildness in the bees, and causes a strong smell in the hives. The bees should be fed on thyme, the white sort is better than the red. In close weather they should have a cool place, and a warm one in the winter. They suffer the most when they work with materials affected with the rust.
