On multiplying colonies to any desirable extent, without their swarming

This large drawer, N, should always be used for this purpose. Insert slides, as in Rule 6, and remove the drawer containing bees and brood-comb; place the same in the chamber of an empty hive; stop the entrances of both the new and old hives, taking care to give them air, as in Rule 4. Give clean water daily, three or four days. Now let the bees, in both hives, have their liberty.

Remarks.

This operation is both practicable and easy, and is of prime importance to all cultivators, who wish to avoid the necessity of hiving them when they swarm; and yet it will not prevent swarming, except in that part of the divided colony which contains the Queen at the time of their separation. The other part being compelled to make another Queen, (and they generally make two or more) will be likely to swarm to avoid their battle, as explained in remarks on Rule 2. The hive containing the old Queen may swarm for want of room; but, at any rate, in performing the operation, it has saved the trouble of hiving one swarm, and prevented all danger of their flight to the woods.

Multiplying colonies by this rule is a perfectly safe method of managing them, admitting they are not allowed to swarm themselves so low as to leave unoccupied combs, which will be explained in remarks on Rule 10.
