She mates once in her life, when she is a few days old, with a single drone, and on the wing. That is the only occasion of her leaving the hive, except when she leads forth a swarm. Her grand function is to lay eggs, and every part of her structure and every power she has is more or less related to this all-important duty. She is, as we have implied, freed from every other office. The hatching, the tending, the rearing, the instruction of her progeny, are entirely taken out of her hands, and it is doubtful whether she has any affection for her children. She is constantly attended by a retinue of ten or twelve "maids of honour," who all keep their heads turned towards her, clear the way for her, prevent all crowding round her, and supply her with the most nutritious food, previously half digested by themselves. They caress her with their antennæ, and seem to find a real joy in mere proximity to their monarch. Should she, by more rapid movements than usual, outstrip her retiring attendants, the bees with whom she thus unexpectedly comes in contact appear excited and alarmed, and move hastily from her path. So long as she remains sound and well in the hive, all the varied works go on peacefully and incessantly. Should she die or be removed, immediate consternation is manifested. Her subjects rush about in excitement and distress. They buzz around the neighbourhood of the hive, but all active and productive work ceases. They know that unless the disastrous loss can be repaired, their community must perish for lack of new progeny, and when despair seizes them, they seem to act upon the motto, "Let us eat and drink, for to-morrow we die." But the skilled bee-keeper comes to the rescue when he has ascertained the death or loss of a queen, and introduces another monarch to the distressed community. Care and caution, however, have to be exercised in this operation; for, until convinced that there is no hope of the restoration of their rightful sovereign, the workers will not tolerate a substitute for her. Even when their hopes are extinguished, it is much safer to cage the new queen, for thirty-six or forty-eight hours, on a comb, so that a gradual acquaintance with one another may be formed before free intercourse is allowed. Otherwise, it will frequently happen that the introduced mother-bee will come to grief by stings or by suffocation. Cases, indeed, have occurred in which it has been found impossible to induce a hive to receive a stranger queen, and it has become necessary to amalgamate such a community with another already possessed of a monarch.
