Bees need but little air at any time when they rob, and yet more is necessary for them when confined by compulsory means, than otherwise. When deprived of their liberty, they soon become restless, and use their best efforts to make their way out of the hive--hence the importance of leaving a small space all around the bottom, to admit air and to prevent their melting down. RULE V. ON EQUALIZING COLONIES. Hive one swarm in the lower apartment of the hive; collect another swarm in a drawer, and insert the same in the chamber of the hive containing the first. Then, if the swarms are small, collect another small swarm in another drawer, and insert the same in the chamber of the hive containing the first, by the side of the second. In case all the bees from either of the drawers, amalgamate and go below with the first swarm, and leave the drawer empty, then it may be removed, and another small swarm added in the same manner. REMARKS. It is of prime importance to every bee cultivator, that all his colonies be made as nearly equal in numbers and strength, as possible. Every experienced bee-master must be aware that small swarms are of but little profit to their owner. Generally, in a few days after they are hived, they are gone;--no one can trace their steps: some suppose they have fled to the woods--others, that they were robbed: but after all, no one is able to give any satisfactory account of them. Some pieces of comb only are left, and perhaps myriads of worms and millers finish off the whole. Then the moth is supposed to be their destroyer, but the true history of the case is generally this: The bees become discouraged, or disheartened, for want of numbers to constitute their colony, abandon their tenement, and join with their nearest neighbors, leaving their combs to the merciless depredations of the moth. They are sometimes robbed by their adjoining hives, and then the moths finish or destroy what is left. Second swarms are generally about half as large as the first, and third swarms half as large as second ones. Now if second swarms are doubled, so as to make them equal in number with the first, the owner avails himself of the advantage of a strong colony, which will not be likely to become disheartened for want of numbers, nor overcome by robbers from stronger colonies. It is far less trouble, and less expense, for the bee-owner lo equalize his colonies, than to prepare hives and drawers of different sizes to fit colonies. When colonies and hives are made as near alike as possible, many evils are avoided, and many advantages realized: every hive will fit a place in the apiary--every drawer a hive, and every bottom board and slide may in any case be used without mistakes.
