Sex of bees.
Loss of queens.
A prosperous bee-colony managed on modern lines will in the height of summer consist of three kinds of bees: a queen or mother-bee, a certain number of drones, and from 80,000 to 100,000 workers. With regard to sex, the queen is a fully-developed female, the drones are males and the workers may be termed neuters or partially developed females. These last possess ovaries like the queen, but shrunken and aborted so as to render the insect normally incapable of egg-production. The relative importance of the three kinds of bees, differs greatly in a degree and in somewhat curious fashion. For instance, the queen (or "king" of the hives as it was termed by our forefathers) is of paramount importance at certain seasons, her death or disablement during the period when the male element is absent meaning extinction of the whole colony. Fecundation would under such conditions be impossible, and without this the eggs of a resultant queen will produce nothing but drones. During the summer season, however (from May to July), when drones are abundant, the loss of a queen is of comparatively little moment, as the workers can transform eggs (or young larvae not more than three days old), which would in the ordinary course produce worker bees, into fully-developed queens, capable of fulfilling all the maternal duties of a mother-bee. The value of this wonderful provision of nature to the bee-keeper of today may be estimated from the fact that bees managed according to modern methods are necessarily subject to so much manipulating or handling, that fatal accidents are as likely to happen in bee life as among human beings.
Authorities differ with regard to the age during which the queen bee is useful to the bee-keeper who works for profit. Under normal conditions the insect will live for three, four or sometimes five years, but the stimulation given together with the high-pressure system followed in modern bee-management, exhausts the period of her greatest fecundity in two years, so that queens are usually superseded after their second season has expired and egg-production gradually decreases. This can hardly cause wonder if it is borne in mind that for many weeks during the height of the season a prolific queen will deposit eggs at the rate of from two to three thousand every twenty-four hours.
The drone.
Drones (or male bees) are more or less numerous in hives according to the skill of the bee-keeper in limiting their production. It is admitted by those best able to judge that the proportion of about a hundred drones in each hive is conducive to the prosperity of the colony, but beyond that number they are worse than useless, being non-producers and heavy consumers. Thus in times of scarcity, which are not infrequent during the early part of the season, they become a heavy tax upon the food-supply of the colony at the critical period when brood-rearing is accelerated by an abundance of stores, while shortness of food means a falling-off in egg-production. The modern bee-keeper, therefore, allows just so much drone comb in the hive as will produce a sufficient number of drones to ensure queen-mating, while affording to the bees the satisfaction of dwelling in a home equipped according to natural conditions, and containing all the elements necessary to bee-life. The action of the bees themselves makes this point clear, for when the season of mating is past the drone is no longer needed, the providing of winter stores taking first place in the economy of the hive. So long as honey is being gathered in plenty drones are tolerated, but no sooner does the honey harvest show signs of being over than they are mercilessly killed and cast out of the hive by the workers, after a brief idle life of about four months' duration. Thus the "lazy yawning drone," as Shakespeare puts it, has a short shrift when his usefulness to the community is ended.
The worker-bee.
Longevity in bees.
Finally we have the aptly named worker-bee, on whom devolves the entire labour of the colony. The worker-bee is incapable of egg-production and can therefore take no part in the perpetuation of its species, so that individually its value to the community is infinitesimal. Yet it forms an item in a commonwealth, the members of which are in all respects equally well endowed. They are in turn skilled scientists, architects, builders, artisans, labourers and even scavengers; but collectively they are the rulers on whom the colony depends for the wonderful condition of law and order which has made the bee-community a model of good government for all mankind. Then so far as regards longevity, the period of a worker-bee's existence is not measured by numbering its days but simply by wear and tear, the marvellous intricacy and wonderful perfection of its framework being so delicate in construction that after six or seven weeks of strenuous toil, such as the bee undergoes in summer time, the little creature's labour is ended by a natural death. On the other hand, worker-bees hatched in the autumn will seven months later be strong with the vigour of lusty youth, able to take their full share in the labour of the hive for six weeks or more in the early spring, which is the most critical period in the colony's existence; hence the value to the apiarist of bees hatched in the autumn.
The mission of the worker-bee is _work_; not so much for itself as for the younger members of the community to which it belongs. We cannot claim for it the virtue of strict honesty with regard to the stranger, but for its own "kith and kin" it is a model of socialism in an ideal form, possessing nothing of its own yet toiling unceasingly for the good of all. The increasing warmth of each recurring spring finds the bee awake, and full of eagerness to be up and doing; its sole mission being apparently to accomplish as much work as possible while life lasts. The earliest pollen is sought out from far and near, and has its immediate effect upon the mother bee of the colony. If healthy and young she begins egg-laying at once, and brood-rearing proceeds at an ever-increasing rate as each week passes, until the hive is brimming over with bees in time for the first honey flow. Then comes the almost human foresight with which the bee prevents the inevitable chaos created by an overcrowded home. There is no cell-room either for storing the abundant supply of food constantly being brought in, or for the thousands of eggs which a prolific queen will produce daily as a consequence of general prosperity; therefore unless help comes from without an exodus is prepared for, and what is known as "swarming" takes place.
Swarming.
Hiving swarms.
It would be difficult to imagine anything more exhilarating to a beginner in bee-keeping than the sight of his first hive in the act of swarming. The little creatures are seen rushing in frantic haste from the hive like a living stream, filling the air with ever-increasing thousands of bees on the wing. The incoming workers returning pollen-laden from the fields, carried away by the prevailing excitement, do not stop to unload their burdens in the old home, but join the enthusiastic emigrants, tumbling over each other pell-mell in the outrush; among them the queen of the colony will in due course have taken her place, bound like her children for a new home. It soon becomes apparent to the onlooker when the queen has joined the flying multitude of bees in the air, for they are seen to be closing up their ranks, and in a few moments begin to form a solid cluster, usually on the branch of a small tree or bush close to the ground. When this stage of swarming is reached the bee-keeper has but to take his hiving skep, hold it under the swarm, and shake the bees into it, preparatory to transferring them into a frame-hive already prepared for their reception. The process of hiving a swarm is very simple and need not occupy many moments of time under ordinary conditions, but so many unlooked-for contingencies may arise that the apiarist would do well to prepare himself beforehand by carefully reading the directions in his text-book.
[Illustration: FIG. 25.--Honeycomb, Metamorphoses of the Honey Bee.
(From Cheshire's _Bees and Bee-keeping, Scientific and Practical_.)]
The illustration given in fig. 25 will serve more readily than words to enlighten the would-be bee-keeper. It shows a portion of honeycomb (natural size) not precisely as it appears when the frame containing it is lifted out of the hive, but as would be seen on two or more combs in the same hive, namely, the various cells built for--and occupied by--queens, drones and workers; also the larvae or grubs in the various stages of transformation from egg to perfect insect, with the latter biting their way out of sealed cells. It also shows sealed honey and pollen in cells, &c. To familiarize himself with the various objects depicted, all of which are drawn from nature, will not only help the reader to understand the different phases of bee-life during the swarming season, but tend to increase the interest of beginners in the pursuit. "Early drones, early swarms" was the ancient bee-man's favourite adage, and the skilled apiarist of to-day experiences the same pleasurable thrill as did the skeppist of old at the sight of the first drone of the year, which betokens an early swarm. As the drones increase in number queen-cells are formed, unless steps be taken to turn aside the swarming impulse by affording additional room beforehand in the hive. The above brief outline of the guiding principles of natural swarming is merely intended as introductory to the fuller information given in a good text-book.
Bee-forage in U.S.A.
_Management of an Apiary._--The main consideration in establishing an apiary is to secure a favourable location, which means a place where honey of good marketable quality may be gathered from the bee-forage growing around without any planting on the part of the bee-keeper himself. It is impossible to deal here with the varying conditions under which apiculture is carried on in all parts of the world, but, as a rule, the same principle applies everywhere. The bee industry prospers greatly in America, where amid the vast stretches of mountain and canyon in California the bee-forage extends for miles without a break, and the climatic conditions are so generally favourable as to reduce to a minimum the chances of the honey crop failing through adverse weather.
The bee-keeper's object is to utilize to the utmost the brief space of a worker-bee's life in summer, by adopting the best methods in vogue for building up stocks to full strength before the honey-gathering time begins, and preparing for it by the exercise of skill and intelligence in carrying out this work.
Value of pollen.
The queen of bee-plants.
In the United Kingdom there is a difference of several weeks in the honey season between north and south. Swarming usually begins in May in the south of England, and in mid-July in the north of Scotland, the issue of swarms coinciding with the early part of the main honey flow. The weather is naturally more precarious in autumn than earlier in the year, and chances of success proportionately smaller for northern bee-men, but the disadvantage to the latter is more than compensated for by the heather season, which extends well into September. With regard to the British bee-keeper located in the south, the early fruit crop is what concerns him most, and where pollen (the fertilizing dust of flowers) is plentiful his bees will make steady progress. If pollen is scarce, a substitute in the form of either pea-meal or wheaten flour must be supplied to the bees, as brood-rearing cannot make headway without the nitrogenous element indispensable in the food on which the young are reared. But the main honey-crop of both north and south is gathered from the various trifoliums, among which the white Dutch or common clover (_Trifolium repens_) is acknowledged to be the most important honey-producing plant wherever it grows. In the United States, Canada, Australia, New Zealand and in many other parts of the world honey of the finest quality is obtained from this "queen of bee-plants," and in lesser degree from other clovers such as sainfoin, alsike (a hybrid clover), trefoil, &c.
British and American methods.
Before undertaking the management of a modern apiary, the bee-keeper should possess a certain amount of aptitude for the pursuit, without which it is hardly possible to succeed. He must also acquire the ability to handle bees judiciously and well under all imaginable conditions. In doing this it is needful to remember that bees resent outside interference with either their work or their hives, and will resolutely defend themselves when aroused even at the cost of life itself. Experience has also proved that, when alarmed, bees instinctively begin to fill their honey-sacs with food from the nearest store-cells as a safeguard against contingencies, and when so provided they are more amenable to interference. The bee-keeper, therefore, by the judicious application of a little smoke from smouldering fuel, blown into the hive by means of an appliance known as a bee-smoker, alarms the bees and is thus able to manipulate the frames of comb with ease and almost no disturbance. The smoker (fig. 26) devised by T.F. Bingham of Farwell, Michigan, U.S.A., is the one most used in America and in the United Kingdom. No other protection is needed beyond a bee-veil of fine black net, which slipped over a wide-brimmed straw hat protects the face from stings when working among bees; as experience is gained the veil is not always used. The man who is hasty and nervous in temperament, who fears an occasional sting, and resents the same by viciously killing the bee that inflicts it will rarely make a good apiarist. The methods of handling bees vary in different countries, this being in a great measure accounted for by the number of hives kept. Very few apiaries in the United Kingdom contain more than a hundred hives; consequently the British bee-keeper has no need for employing the forceful or "hustling" methods found necessary in America, where the honey-crop is gathered in car-loads and the hives numbered by thousands. It naturally follows that bee-life is there regarded very slightly by comparison, and the bee-garden in England becomes the "bee-yard" in America, where the apiarist when at work must thoroughly protect himself from being stung, and, safe in his immunity from damage, cares little for bee-life in getting through his task, the loss of a few hundred bees being considered of no account. There are, however, other reasons, apart from humanity, to account for the difference in handling bees as advocated in the United Kingdom. The great majority of apiaries owned by British bee-keepers are located in close proximity to neighbours; consequently a serious upset among the bees would in many cases involve an amount of trouble which should if possible be avoided; therefore quietness and the exercise of care when manipulating are always recommended by teachers, and practised by those who wisely take their lessons to heart.

Chosing a location.
Bee-keeping for profit.
Having made himself proficient in practical bee-work and chosen a suitable location for his apiary, the bee-keeper should carefully select the particular type of hive most suited to his means and requirements. This point settled, uniformity is secured, and all loose parts of the hives being interchangeable time will be saved during the busy season when time means money. Beginning with not too many stocks he can test the capabilities of his location before investing much capital in the undertaking, so that by utilizing the information already given and adopting the wise adage "make haste slowly" he will realize in good time whether it will pay best to work for honey in comb or extracted honey in bulk; not only so, but the knowledge gained will enable him to select such appliances as are suited to his needs. As a rule, it may be said that the man content to start with an apiary of moderate size--say fifty stocks--may realize a fair profit from comb-honey only; but so limited a venture would need to be supplemented by some other means before an adequate income could be secured. On the other hand, the owner of one or two hundred colonies would find it more lucrative to work for extracted honey and send it out to wholesale buyers in that form. By so doing a far greater weight of surplus per hive may be secured, and extracted honey will keep in good condition for years, while comb-honey must be sold before granulation sets in. At the same time it is but fair to say that bee-culture in the United Kingdom, if limited to honey-production alone, is not sufficiently safe for entire reliance to be placed on it for obtaining a livelihood. The uncertain climate renders it necessary to include either other branches of the craft less dependent on warmth and sunshine, or to combine it with fruit-growing, poultry-rearing, &c. Under such conditions the bees will usually occupy a good position in the balance-sheet.
Need of forethought.
Another indispensable feature of good bee-management is "forethought," coupled with order and neatness; the rule of "a place for everything and everything in its place" prepares the bee-keeper for any emergency; constant watchfulness is also necessary, not only to guard against disease in his hives, but to overlook nothing that tends to be of advantage to the bees at all seasons. Among the many ways of saving time nothing is more useful than a carefully-kept note-book, wherein are recorded brief memoranda regarding such items as condition of each stock when packed for winter, amount of stores, age and prolific capacity of queen, strength of colony, healthiness or otherwise, &c., all of which particulars should be noted and the hives to which they refer plainly numbered. It also enables the bee-keeper to arrange his day's work indoors while avoiding disturbance to such colonies as do not need interference. In the early spring stores must be seen to and replenished where required; breeding stimulated when pollen begins to be gathered, and appliances cleaned and prepared for use during the busy season.
Length of bee season.
Swarm prevention.
The main honey-gathering time (lasting about six or seven weeks) is so brief that in no pursuit is it more important to "make hay while the sun shines," and if the bee-keeper needs a reminder of this truism he surely has it in the example set by his bees. As the season advances and the flowers yield nectar more freely, visible signs of comb-building will be observed in the whitened edges of empty cells in the brood-chambers; the thoughtful workers are lengthening out the cells for honey-storing, and the bee-master takes the hint by giving room in advance, thus lessening the chance of undesired swarms. In other words, order and method, combined with the habit of taking time by the forelock, are absolutely necessary to the bee-keeper, seeing that the enormous army of workers under his control is multiplying daily by scores of thousands. As spring merges into summer, sunny days become more frequent; the ever-increasing breadth of bee-forage yields still more abundantly, and the excitement among the labourers crowding the hives increases, rendering room in advance, shade and ventilation, a _sine qua non_. It requires a level head to keep cool amongst a couple of hundred strong stocks of bees on a hot summer's day in a good honey season. Moreover, it will be too late to think of giving ventilation at noontide, when the temperature has risen to 80 deg. F. in the shade; the necessary precautions for swarm prevention must therefore be taken in advance, for when what is known as the "swarming fever" once starts it is most difficult to overcome.
The well-read and intelligent bee-keeper, content to work on orthodox lines, will be able to manage an apiary--large or small--by guiding and controlling the countless army he commands in a way that will yield him both pleasure and profit. All he needs is good bee weather and an apiary free from disease to make him appreciate bee-craft as one of the most remunerative of rural industries; affording a wholesome open-air life conducive to good health and yielding an abundance of contentment.
_Diseases of Bees._--It is quite natural that bees living in colonies should be subject to diseases, and only since the introduction of movable-comb hives has it been possible to learn something about these ailments. The most serious disease with which the bee-keeper has to contend is that commonly known as "bee-pest" or "foul brood," so called because of the young brood dying and rotting in the cells. This disease has been known from the earliest ages, and is probably the same as that designated by Pliny as _blapsigonia (Natural History_, bk. xi. ch. xx.). Coming to later times, Della Rocca minutely describes a disease to which bees were subject in the island of Syra, between the years 1777 and 1780, and through which nearly every colony in the island perished. From the description given it was undoubtedly foul brood, and the bee-keepers of the island became convinced, after bitter experience, that it was extremely contagious. Schirach also mentioned and described the disease in 1769, and was the first to give it the name of "foul brood." Still later, in 1874, Dr Cohn, after the most exhaustive experiments and bacteriological research, realized that the disease was caused by a bacillus, and--nine years later--the name _Bacillus alvei_ was given to it by Cheyne and Cheshire, whose views were in agreement with those of Dr Cohn.
The illustration (fig. 27) shows a portion of comb affected with foul brood in its worst form. The sealed cells are dark-coloured and sunken, pierced with irregular holes, and the larvae in all stages from the crescent-shaped healthy condition to that in which the dead larvae are seen lying at the bottom of the cells, flaccid and shapeless. The remains then change to buff colour, afterwards turning brown, when decomposition sets in, and as the bacilli present in the dead larvae increase and the nutrient matter is consumed, the mass in some cases becomes sticky and ropy in character, making its removal impossible by the bees. In course of time it dries up, leaving nothing but a brown scale adhering to the bottom or side of the cell. In the worst cases the larvae even die after the cells are sealed over; a strong characteristic and offensive odour being developed in some phases of the disease, noticeable at times some distance away from the hive.
[Illustration: FIG. 27.--Foul Brood (_Bacillus alvei_).
(From Cheshire's _Bees and Bee-keeping, Scientific and Practical._)]
Two forms of foul brood have been long known, one foul smelling, the other odourless; and investigations made during 1906 and 1907 showed that the etiology of the disease is not by any means simple, but that it is produced by different microbes, two others in addition to _Bacillus alvei_ playing an important part. These are _Bacillus brandenburgiensis_, Maassen (syn. _B. burri_, Burri: _B. larvae_, white), and _Streptococcus apis_, Maassen (syn. _B. Guntheri_, Burri). The first two are found in both forms of foul brood, whereas the last is only present with _B. alvei_ in the strong-smelling form of the disease, in which the larvae are attacked prior to the cells being sealed over.
