It will be obvious that this whole process, in order to be successfully performed, requires a knowledge of the most important points in the economy of the bee-hive; indeed the same remark may be made of almost any operation, and those who are willing to remain ignorant of the laws which regulate the breeding of bees, ought not to depart in the least, from the old-fashioned mode of management. All such deviations will only be attended with a wanton sacrifice of bees. A man may use the common swarming hives a whole life-time, and yet remain ignorant of the very first principles in the physiology of the bee, unless he gains his information from other sources; while, by the use of my hives, any intelligent cultivator may, in a single season, verify for himself, the discoveries which have only been made by the accumulated toil of many observers, for more than two thousand years. The ease with which Apiarians may now, by the sight of their own eyes, gain a knowledge of all the important facts in the economy of the hive, will stimulate them most powerfully, to study the nature of the bee and thus to prepare themselves for an enlightened system of management. In giving directions for the creation of forced swarms, I advised that it should be done during the pleasantest part of the day, when the largest number of bees are foraging abroad. If the operation is performed when all the bees are at home, and they are all driven into the empty hive, the old hive will be so depopulated that many of the young will perish for want of suitable attention, and the parent stock will be greatly deteriorated in value. If only a part of the bees are expelled, the queen may be left behind, and the whole operation will be a failure, and at best it will be difficult to make a suitable division of the bees between the two hives. Indeed, under any circumstances, this is the most difficult part of the process, and it often requires no little judgment to equalize the two colonies.
