After the swarm has been taken in the usual way into an empty box, or into a straw-hive, and suffered to settle and cluster therein for an hour or two, gently and with a steady hand take the box or hive, and, having a tub of clean water placed ready and conveniently for the purpose, with a sudden jerk dislodge the Bees from the box or hive and immerse them in the water. Let them remain therein two or three minutes: then drain it off through a sieve, or other strainer, and spread the now harmless Bees--harmless, because apparently half-drowned, upon a dry towel or table-cloth, and search for and _secure the Queen_. This done, and which may very easily be done, place a board or two in a slanting direction from the entrance of the parent-hive to the ground; upon this lay the cloth on which are your immersed Bees, and spread them thinly over it, in order that they may the sooner become dry; and, as they become dry, you will with pleasure see them return to their native-hive, which they will be permitted to enter without the slightest opposition from the Bees already therein. By this operation not only are the immersed Bees cooled, but their re-union with those already in the hive cools them also, and considerably lowers the temperature of the whole stock. With a late swarm from any sort of hive, as well as with an accidental swarm from boxes, this is a good method to be adopted; and, if the apiarian possess sufficient coolness and dexterity to perform it cleverly, it is a practice I would recommend whenever it is advisable to return a swarm to its native-hive. When a swarm has thus been returned to a cottage-hive an eke should be added forthwith. Before I further explain the nature of my collateral Bee-boxes, I shall briefly express my desire that my readers will attend particularly to the discovery of the effects of ventilation. I have been asked--"Of what use is ventilation in the domicil of Bees?" I answer--one of its uses has already been described, and much more of its use, I may say, of its necessity, in the humane management of Bees will be told presently. Many treatises on the management of these valuable insects have appeared, but in none of them do I find any allusion to this important point--important in my practice at least, and essentially necessary in it. Therefore-- To works of Nature join the works of man, To show, by art improved, what Nature can. Nature's great efforts can no further tend, Here fix'd her pillars, all her labours end. Dryden.
