Hives found to be queenless may be supplied either with matured queens or with queen cells. If the latter are sufficiently numerous, their introduction may easily be effected by exchanging a comb in each hive; if they have to be cut out and placed loosely in the new hive, a triangular piece of comb should then be removed with them, to be used as a block in preventing any pressure coming on them. A space must be cut out of the middle in the centre combs of the hive into which they are to be introduced. Special care must be taken not to bruise the royal embryos, as they are particularly sensitive to pressure. A very great advantage that the Woodbury bar and frame-hive possesses, is the safety and convenience with which a stock of bees can in it be transported to any part of the kingdom; and, by a few additional arrangements, stocks have been sent in it to distant countries. In many districts hives are removed to moors and heaths in autumn, for the purpose of gathering heather honey. In this operation the frames are a great support to the combs, very much lessening the risk of a break down and consequent loss. From a hive that has been inhabited all the winter, we have not unfrequently lifted out the frames and removed the stock to a clean hive, and we believe that the change has always been useful. The bees find a clean floorboard and a clean hive to breed in, free from insects that may have harboured in crevices about the hive. When the change has been made, the old hive can be thoroughly cleaned, and used in the same way for making the exchange with another stock. The process for handling will, of course, be the same as before described. We have found that where this plan has been carried out, that the bees seem to progress faster. Perhaps a little stirring up may be useful in arousing them from the winter doze; the time we recommend for doing this is the beginning of April, but a fine warm day should be chosen. 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 floorboard; 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.
