In twenty-one days the bee emerges from the cell. The old writers were quite mistaken in thinking that the advent of these was an occasion of joy and excitement among the bees. All apiarists have noticed how utterly unmoved the bees are, as they push over and crowd by these new-comers in the most heedless and discourteous manner imaginable. Wildman tells of seeing the workers gathering pollen and honey the same day that they came forth from the cells. This idea is quickly disproved if we Italianize black-bees. We know that for some days these young bees do not leave the hive at all, except in case of swarming, when bees even too young to fly will essay to go with the crowd. These young bees, like the young drones and queens, are much lighter for the first few days.
The worker-bees never attain a great age. Those reared in autumn may live for eight or nine months, and if in queenless stocks, where little labor is performed, even longer; while those reared in spring will wear out in three, and when most busy, will often die in from thirty to forty-five days. None of these bees survive the year through, so there is a limit to the number which may exist in a colony. As a good queen will lay, when in her best estate, three thousand eggs daily, and as the workers live from one to three months, it might seem that forty thousand was too small a figure for the number of workers. Without doubt a greater number is possible. That it is rare is not surprising, when we remember the numerous accidents and vicissitudes that must ever attend the individuals of these populous communities.
The function of the worker-bees is to do all the manual labor of the hives. They secrete the wax, which forms in small pellets ([Fig, 27, a, a]) under the over-lapping rings under the abdomen. I have found these wax-scales on both old and young. According to Fritz Müller, the admirable German observer, so long a traveler in South America, the bees of the genus melipona secrete the wax on the back.
The young bees build the comb, ventilate the hive, feed the larvæ and cap the cells. The older bees—for, as readily seen in Italianizing, the young bees do not go forth for the first one or two weeks—gather the honey, collect the pollen, or bee-bread, as it is generally called, bring in the propolis or bee glue, which is used to close openings, and as a cement, supply the hive with water(?), defend the hive from all improper intrusion, destroy drones when their day of grace is past, kill and arrange for replacing worthless queens, destroy inchoate queens, drones, or even workers, if circumstances demand it, and lead forth a portion of the bees when the conditions impel them to swarm.
When there are no young bees, the old bees will act as house-keepers and nurses, which they otherwise refuse to do. The young bees, on the other hand, will not go forth to glean, even though there be no old bees to do this necessary part of bee-duties. An indirect function of all the bees is to supply animal heat, as the very life of the bees require that the temperature inside the hive be maintained at a rate considerably above freezing. In the chemical processes attendant upon nutrition, much heat is generated, which, as first shown by Newport, may be considerably augmented at the pleasure of the bees, by forced respiration. The bees, too, by a rapid vibration of their wings, have the power to ventilate their hives, and thus reduce the temperature, when the weather is hot. Thus they moderate the heat of summer, and temper the cold of winter.

CHAPTER III.
SWARMING OR NATURAL METHOD OF INCREASE.
The natural method by which an increase of colonies among bees is secured, is of great interest, and though it has been closely observed, and assiduously studied for a long period, and has given rise to theories as often absurd as sound, yet, even now, it is a fertile field for investigation, and will repay any who may come with the true spirit of inquiry, for there is much concerning it which is involved in mystery. Why do bees swarm at unseemly times? Why is the swarming spirit so excessive at times and so restrained at other seasons? These and other questions we are too apt to refer to erratic tendencies of the bees, when there is no question but that they follow naturally upon certain conditions, perhaps intricate and obscure, which it is the province of the investigator to discover. Who shall be first to unfold the principles which govern these, as all other actions of the bees?
In the spring or early summer, when the hive has become populous, and storing very active, the queen, as if conscious that a home could be overcrowded, and foreseeing such danger, commences to deposit drone-eggs in drone-cells, which the worker-bees, perhaps moved by like considerations, begin to construct, if they are not already in existence. In fact, drone comb is almost sure of construction at such times. No sooner is the drone brood well under way, than the large, awkward, queen-cells are commenced, often to the number of ten or fifteen, though there may be not more than three or four. In these, eggs are placed, and the rich royal jelly added, and soon, often before the cells are even capped—and very rarely before a cell is built, if the bees are crowded, the hives unshaded, the ventilation insufficient, or the honey-yield very bountiful—some bright day, usually about ten o'clock, after an unusual disquiet both inside and outside the hive, a large part of the worker-bees—being off duty for the day, and having previously loaded their honey-sacks—rush forth from the hive as if alarmed by the cry of fire, the queen among the number, though she is by no means among the first, and frequently is quite late in her exit. The bees, thus started on their quest for a new home, after many uproarious gyrations about the old one, dart forth to alight upon some bush, limb, or fence, though in one case I have known the first swarm of bees to leave at once, for parts unknown, without even waiting to cluster. After thus meditating for the space of from one to three hours, upon a future course, they again take wing and leave for their new home, which they have probably already sought out.
