After looking at these powerful stocks in what may be called log-cabin hives, let us examine some in the most costly hives, which have ever been constructed; in what have been called real "Bee-Palaces;" and we shall often find them weak and impoverished, infested and almost devoured by the worms. Their owner, with books in his hand, and all the newest devices and appliances in the Apiarian line, unable to protect his bees against their enemies, or to account for the reason why some hives seem, like the children of the poor, almost to thrive upon ill-treatment and neglect, while others, like the offspring of the rich and powerful, are feeble and diseased, almost in exact proportion to the means used to guard them against noxious influences, and to minister most lavishly to all their wants. I once used to be much surprised to hear so many bee-keepers speak of having "good luck," or "bad luck" with their bees; but really as bees are generally managed, success or failure does seem to depend almost entirely upon what the ignorant or superstitious are wont to call "luck." I shall now try to do what I have never yet seen satisfactorily done by any writer on bees; viz.: show exactly under what circumstances the bee-moth succeeds in establishing itself in a hive; thus explaining why some stocks flourish in spite of all neglect, while others, in the common hives, fall a prey to the moth, let their owner be as careful as he will, I shall finally show how in suitable hives, with proper precautions, it may always be kept from seriously annoying the bees.
