The cell in which a queen bee is developed differs greatly from that of the worker, not only in form, but in many other respects. The cells in which workers are developed are sexangular tubes. These are arranged horizontally, or nearly so, and form one compact mass. Each of these six walls form a division between any two cells. The arrangement and the massing of these cells form what is familiarly termed brood comb or honey comb. How unlike these are the queen cells. They are circular tubes that hang perpendicularly from the workers' cells. Workers' cells are always built of new material--there are occasional exceptions ; but queen cells are always built of old material without exception. The workers' cells are used for two purposes--unversies and storage ; queens' cells as nurseries only. These are detailed contradistinctions sufficient for my purpose. Note, if the queen lays an egg in a worker cell, and within two or three days lays another in a queen cell, naturally we shall have a queen from the latter and a worker from the former cell ; but if we apply art, and transpose those eggs, we differentiate the entire creatures that are developed therefrom, checking the evolution of a queen to a worker, reducing the period by about five days by altering its surroundings and other conditions; but we extend the evolution of the worker to a queen by the same time, from the same cause, and the same altered conditions. The queen cells are, as a rule, built on the sides or base of the brood comb. Occasionally a pop-hole--that is the hole frequently seen in honey comb or brood comb to permit the bees passing from side to side of the comb--is enlarged, and the queen cell constructed on the upper edge thereof. And again, it is sometimes met with as if protruding from a worker cell. These latter are only constructed in cases of emergency. From some cause or -other the queen becomes sick, or her laying powers become deranged, or from some other cause she ceases to lay. When the bees make this discovery, their instinct naturally leads them to rectify the queen's omission. The discovery that no eggs are being deposited by the queen causes great anxiety in the hive. Instinctively they know that where there are no eggs there will be no workers, and where there are no workers there will be no food, and thus the continuation of the home must speedily come to an end. The development of queens is entirely left to the workers. After the queen has laid the egg, her duty with it ceases. The workers know that any or every egg or larva is not suitable for queen development. Occasionally, under the stress of the impossible, cases have been known where the bees have chosen a drone egg or larva with the idea of developing a queen therefrom, the reason being that every other avenue, of continuing their species had been closed against them. This is bee ignorance, caused by anxiety. Those emergency cells protruding from the workers' are constructed over a larva from a similar cause, it being the best within the hive to select for the purpose of developing a queen therefrom. The queens evolved from such cells are always far inferior to those evolved from cells constructed of the edges of the combs.
