The formation of one new swarm from two old colonies, may, of course, be very much simplified by the use of my hives. The two old hives are first opened and sprinkled, and the bees taken from them and put into the new hive in the same way in which the process was conducted when only one colony was expelled, some brood comb being given to the united family. There will be no difficulty in rightly proportioning the bees; one queen may always be caught and preserved, and the operation may be performed at any time when the sun is above the horizon. I have no doubt that those who have a strong stock of bees, and who are anxious to realize the largest profits in honey, will find this mode of increase, by far the simplest and best. If judiciously practiced, they will find that their colonies may always be kept powerful, and that they may be managed with very great economy in time and labor. As Apiarians may be so situated as to wish to increase their bees quite rapidly, I shall give such methods as from numerous experiments, many of them conducted on a large scale, I have found to be the best. I wish it however to be most distinctly understood, that I do not consider _very_ rapid multiplication as likely to succeed, except in the hands of skillful Apiarians; and under ordinary circumstances it requires too much time, care and honey, to be of very great practical value. Its chief merit consists in the short time which it requires to build up an Apiary. After trying my mode of management for a few seasons, a bee-keeper may find out, that he is in all respects, favorably situated for taking care of a large stock of bees. Suppose him to have acquired both skill and confidence, and that he has ten powerful colonies. If he is willing to do without surplus honey for one season, and the honey-harvest should be very productive, he may without feeding, and without very much labor, safely increase his ten colonies to thirty. If he chooses to feed largely, he may _possibly_ end the season with fifty or sixty, or even more; but he will _probably_ end it in such a manner as most thoroughly to disgust him with his folly, and to teach him that in bee-keeping, as well as in other things, "Haste makes waste."
