The frames now filled are placed in the hive, when the bees may be let into it in the manner Mr. Woodbury recommends for a swarm (see page 220). It may be as well to keep them confined a few hours, giving them water at the top, by means of a soaked sponge laid on perforated zinc, until they make the combs secure; the object of this being to exclude the bees from other hives, who, if feloniously inclined, might come to rob. For the same reason the operation of adjusting the combs should not be performed in the open air, or the bees from surrounding hives will be sure to come in great numbers to obtain a share of the honey necessarily exposed. It should be done inside a room with the temperature at about 70 degrees--not cold enough to chill the brood, nor yet hot enough to soften the combs. An expert apiarian could perform the operation in less than three-quarters of an hour, and with little loss. A week or so after a swarm has left the old stock is perhaps the very best time for such a removal. In some instances a routing of this kind has a beneficial effect; old stocks of hives that have previously appeared to be dwindling are often aroused to activity by their removal into a fresh domicile. After the winter's doze this is especially the case, say if done on a warm day early in April. We have ourselves frequently shifted the stock from a well-occupied frame hive to a fresh one, in which the bees find a clean floor-board and walls, as well as freedom from insects that may have harboured in crevices during the winter. § IV. DRIVING. Driving is an operation by which bees are induced to vacate an, old settled hive and to enter an empty one. Many apiarians prefer this mode of effecting an exchange of hives to the plan of fumigating the bees. The greatest success attending such a transfer will be in the case of hives well filled with combs that are worked nearly to the floor-board; and it may be remarked that bees are generally so far provident that they leave an open space in which to pass underneath their combs over all the floor of the hive. When the old hive is inverted the bees crawl up the combs, and thus more easily pass up into the new hive, which the operator places over the old one with the intent that they should enter it.
