It is now also certain that a skilful bee-master can accustom his bees to the presence of more than one queen. Recent experiments in America on this head, although convincing enough as far as they go, need the test of time before their practical value to apiculture can be rightly estimated. To multiply its domestic deities may prove anything but a blessing to the harmony and welfare of a hive. But the fact has been well established that the old rule, of one queen at a time, may be upset—whether permanently, and for the ultimate advantage of honey-making, time alone can tell. [Picture: Drone-brood and worker-broods] A single queen, when young and vigorous and of good blood, is able to keep an entire hive filled with brood throughout the short honey-gathering season. The brood-nest of a modern frame-bar hive has a comb-surface of over 2,000 square inches, giving about 50,000 cells available for the breeding of young worker-bees. This represents, at times of greatest prosperity, an enormous floating population; but if several queens can be permanently established in one hive, and the hives enlarged to permit each her fullest scope, the figures will soon begin to stretch out into infinity. Two facts are well known to experienced bee-keepers—that a large stock gathers more honey than two small stocks containing between them the same number of individuals; and that, when the honey-crop is in full yield, there are seldom enough bees to harvest it. The whole art of latter-day bee-keeping consists in bringing up the numerical strength of each colony to its fullest in time for the great main nectar-flow. Yet, in a good district and in a good season, when huge areas of clover or sainfoin come into full blossom at the same time, and the nectar must be gathered or lost within the space of a fortnight or so, the most populous apiary is seldom equal to the task. Probably, in exceptional seasons, half the English honey-crop is lost for want of bees to gather it. If, therefore, the new system of plurality of queens both justifies and establishes itself, the near future may see a revolution in all ideas relating to beemanship. All that can be said for certain at present is that as many as five queens have been induced to occupy the same hive in peace and quiet together; but whether this portentous state of affairs can remain a lasting one is still to be proved.
