Part 3
The workers of _Apis_ may be capable (fig. 6, C) of laying eggs--necessarily unfertilized--which always give rise to males ("drones"), and, since the researches of J. Dzierzon (1811-1906) in 1848, it has been believed that the queen bee lays fertilized eggs in cells appropriate for the rearing of queens or workers, and unfertilized eggs in "drone-cells," virgin reproduction or parthenogenesis being therefore a normal factor in the life of these insects. F. Dickel and others have lately claimed that fertilized eggs can give rise to either queens, workers or males, according to the food supplied to the larvae and the influence of supposed "sex-producing glands" possessed by the nurse-workers. Dickel states that a German male bee mated with a female of the Italian race transmits distinct paternal characters to hybrid male offspring. A. Weismann, however, doubts these conclusions, and having found a spermaster in every one of the eggs that he examined from worker-cells, and in only one out of 272 eggs taken from drone-cells, he supports Dzierzon's view, explaining the single exception mentioned above as a mistake of the queen, she having laid inadvertently this single fertilized egg in a drone instead of in a worker cell.
The cells of the honeycomb of _Apis_ are usually hexagonal in form, and arranged in two series back to back (figs. 3, 25). Some of these cells are used for storage, others for the rearing of brood. The cells in which workers are reared are smaller than those appropriate for the rearing of drones, while the "royal cells," in which the young queens are developed, are large in size and of an irregular oval in form (fig. 25). It is believed that from the nature of the cell in which she is ovipositing, the queen derives a reflex impulse to lay the appropriate egg--fertilized in the queen or worker cell, unfertilized in the drone cell, as previously mentioned. Whether the fertilized egg shall develop into a queen or a worker depends upon the nature of the food. All young grubs are at first fed with a specially nutritious food, discharged from the worker's stomach, to which is added a digestive secretion derived from special salivary glands in the worker's head. If this "royal jelly" continue to be given to the grub throughout its life, it will grow into a queen; if the ordinary mixture of honey and digested pollen be substituted, as is usually the case from the fourth day, the grub will become a worker. The workers, who control the polity of the hive (the "queen" being exceedingly "limited" in her monarchy), arrange if possible that young queens shall develop only when the population of the hive has become so congested that it is desirable to send off a swarm. When a young queen has emerged, she stings her royal sisters (still in the pupal stage) to death. Previous to the emergence of the young queen, the old queen, prevented by the workers from attacking her daughters, has led off a swarm to find a new home elsewhere. The young queen, left in the old home, mounts high into the air for her nuptial flight, and then returns to the hive and her duties of egg-laying. The number of workers increases largely during the summer, and so hard do the insects work that the life of an individual may last only a few weeks. On the approach of winter the males, having no further function to perform for the community, are refused food-supplies by the workers, and are either excluded or banished from the hive to perish. Such ruthless habits of the bee-commonwealth, no less than the altruistic labours of the workers, are adapted for the survival and dominance of the species. The struggle for life may deal hardly with the individual, but it results--to quote Darwin's well-known title--in "the preservation of favoured races."
BIBLIOGRAPHY.--More has been written on bees, and especially on the genus _Apis_, than on any other group of insects. The classical observations of Reaumur _Memoires pour servir a l'histoire des insectes_, vols. v., vi. (Paris, 1740-1742) and F. Huber's _Nouvelles observations sur les abeilles_ (Geneve, 1792) will never be forgotten; they have been matched in recent times by J.H. Fabre's _Souvenirs entomologiques_ (Paris, 1879-1891); and M. Maeterlinck's poetic yet scientific _La vie des abeilles_ (Paris, 1901). Among writers on the solitary and parasitic species may be specially mentioned F. Smith, _Hymenoptera in the British Museum_ (London, 1853-1859); H. Friese, _Zool. Jahrb. Syst._, iv. (1891) J. Perez, _Actes Soc. Bordeaux_, xlviii. (1895); and C. Verhoeff, _Zool. Jahrb. Syst._, vi. (1892). For the social species we have valuable papers by E. Hoffer, _Mitt. Naturwissen. Ver. Steiermark_, xxxi. (1881); H. von Jhering, _Zool. Jahrb. Syst._, xix. (1903); and others. For recent controversy on parthenogenesis in the hive bee, see J. Perez, _Ann. Sci. Nat. Zool._ (6), vii. (1878); F. Dickel, _Zool. Anz._, xxv. (1901), and _Anatom. Anzeiger_, xix. (1902); A. Petrunkevich, _Zoolog. Jahrb. Anat._, xiv. (1901); and A. Weismann, _Anatom. Anzeiger_, xviii. (1901). F.R. Cheshire's _Bees and Bee-keeping_ (London, 1885-1888), and T.W. Cowan's _Honey Bee_ (2nd ed., 1904), are invaluable to the naturalist, and contain extensive bibliographies of _Apis_. D. Sharp's summary in the _Cambridge Natural History_, vol. vi., should be consulted for further information on bees generally. British bees are described in the catalogues of Smith, mentioned above, and by E. Saunders, _The Hymenoptera of the British Islands_ (London, 1896). (G. H. C.)
BEE-KEEPING
Bee-keeping, or the cultivation of the honey-bee as a source of income to those who practise it, is known to have existed from the most ancient times. Poets, philosophers, historians and naturalists (among whom may be mentioned Virgil, Aristotle, Cicero and Pliny) have eulogized the bee as unique among insects, endowed by nature with wondrous gifts beneficial to mankind in a greater degree than any other creature of the insect world. We are told that some of these ancient scientists passed years of their lives studying the wonders of bee-life, and left accurate records of their observations, which on many points agree with the investigations of later observers. As a forcible illustration of the manner in which a colony of bees was recognized as the embodiment of government by a chief or ruler, in the earliest times of which there is any existing record, it may be mentioned that on the sarcophagus containing the mummified remains of Mykerinos (now in the British Museum and dating back 3633 years B.C.) will be found a hieroglyphic bee,(fig. 8) representing the king of Lower Egypt.

Queen-rearing.
In dealing with the practical side of bee-keeping as now understood, it may be said that, compared with the methods in vogue during the first decade of the 19th century, or even within the memory of men still living at the beginning of the 20th, it is as the modern locomotive to the stagecoach of a previous generation. Almost everything connected with bee-craft has been revolutionized, and apiculture, instead of being classed with such homely rural occupations as that of the country housewife who carries a few eggs weekly to the market-town in her basket, is to-day regarded in many countries as a pursuit of considerable importance. Remarkable progress has also been made in the art of queen-rearing, and in improving the common or native bee by judicious crossing with the best foreign races, selected mainly for hardiness, working qualities and the prolific capacity of their queens. American bee-breeders are conspicuous in this respect, extensive apiaries being exclusively devoted to the business of rearing queens by the thousand for sale and export.
On the European continent queen-rearing apiaries are plentiful, but less attention is paid there to hybridizing than to keeping the respective races pure. In England also, some bee-keepers include queen-rearing as part of their business, while one large apiary on the south coast is exclusively devoted to the rearing of queen bees on the latest scientific system, and to breeding by selection from such races as are most suited to the exceptional climatic conditions of the country.
Honey as food.
Extensive apiaries have been established on the American continent, some containing from 2000 to 3500 colonies of bees, and in these honey is harvested in hundreds of tons yearly. The magnitude of the bee industry in the United States may be judged from the fact of a single bee-farmer located in California having harvested from 150,000 lb. of honey in one year from 2000 stocks of bees, and, as an instance of the enormous weight of honey obtainable from good hives in that favoured region, the same farmer secured 60,000 lb. of comb-honey in one season from his best 300 colonies. This is probably the maximum, and the hives were necessarily located in separate apiaries some few miles apart in order to avoid the evils of overstocking, but all in the midst of thousands of acres of honey-yielding flowers. Results like the above compared with those of the skeppist bee-keeper of former days, who was well pleased with an average of 20 to 25 lb. per hive, may be regarded as wonderful, but they are matters of fact. The consumption of honey as an article of food has also largely increased of late years; a recent computation shows that from 100 to 125 million lb. of honey, representing a money value of from eight to ten million dollars, is consumed annually in the United States alone. Many of the larger bee-farmers of the United States of America and Canada harvest from 50,000 to 60,000 lb. of honey in a single season, and some of them sell the whole crop direct to consumers.
State aid for bee-keeping.
It is a notable fact that in the United States, Canada, Australia, New Zealand, and indeed all English-speaking countries outside the United Kingdom, honey is far more extensively used than it is there as an article of daily food. The natural result of this is that the trade in honey is conducted, in those countries, on entirely different lines from those followed in the British Isles, where honey production as an occupation has, until quite recent years, been regarded as too insignificant for official notice in any form. The value of the bee industry is now recognized, however, by the British government as worthy of state aid, in the promotion of technical instruction connected with agriculture. On the American continent apiculture is officially recognized by the respective states' governments; and by the federal government at Washington it is taken into account as a section of the Agricultural Department, with fully equipped experimental apiaries and qualified professors engaged therein for educational work. In several Canadian provinces also, the public funds are used in promoting the bee industry in various ways, mainly in combating the bee-disease known as "foul brood." In New Zealand the government of the colony has displayed the most praiseworthy earnestness and vigour in promoting apiculture. State-aided apiaries have been established under the supervision of a skilled bee-keeper, who travels over the colony giving instruction in practical bee-work at the public schools, and forming classes at various centres where pupils are taught bee-keeping in all its branches.
Value of bees as fertilizers.
In Europe similar progress is observable; technical schools, with well-equipped apiaries attached, are supported by the state, and in them the science and practice of modern bee-keeping is taught free by scientists and practical experts. Institutions of this kind have been established in Germany, Russia, Switzerland and elsewhere, all tending in the same direction, viz. the cultivation of the honey-bee as an appreciable source of income to the farmer, the peasant cultivator, and dwellers in districts where bee-forage is abundant and, if unvisited by the bee, lies wasting its sweetness on the desert air. It may be safely said that the value of the bee to the fruit-grower and the market-gardener has been proved beyond dispute; and the technical instruction now afforded by county councils in the rural districts of England has an appreciable effect. In proof thereof, we may quote the case of an extensive grower in the midland counties--sending fruit to the London market in tons--whose crop of gooseberries increased nearly fourfold after establishing a number of stocks of bees in close proximity to the gooseberry bushes. The fruit orchards and raspberry fields of Kent are also known to be greatly benefited by the numerous colonies of bees owned by more than 3000 bee-keepers in the county. The important part played by the bee in the economy of nature as a fertilizer is shown in fig. 9.

Bee-keepers' associations.
Bee and honey shows.
Honey labels.
In the United Kingdom the prevailing conditions, climatic and otherwise, with regard to apiculture--as well as the lack of sufficient natural bee-forage for large apiaries--are such as to preclude the possibility of establishing apiaries on a scale comparable with those located in less confined lands. On the other hand, even in England the value of bee-keeping is worthy of recognition as a minor industry connected with such items of agriculture as fruit-growing, market-gardening or poultry-raising. The fact that British honey is second to none for quality, and that the British market is eagerly sought by the bee-keepers of other nationalities, has of late impressed itself on the minds of thinking men. Moreover, their views are confirmed by the constant references to bees and the profits obtainable from bee-keeping in the leading papers on all sides. This newly-aroused interest in the subject is no doubt to a large extent fostered by the grants in aid of technical instruction afforded by county councils in rural districts. The British Bee-keepers' Association (instituted in 1874) has been untiring in its efforts to raise the standard of efficiency among those who are desirous of qualifying as experts and teachers of bee-keeping on modern methods. This body had for its first president the distinguished naturalist Sir John Lubbock (Lord Avebury). Subsequently the baroness Burdett-Coutts accepted the office in the year 1878, and was re-elected annually until her death in 1906. During this time she presided at its meetings and took an active part in its work, until advancing years prevented her attendance, but her interest in the welfare of the association was maintained to the last. Branch societies of bee-keepers were established throughout the English counties, mainly by the efforts of the parent body in London, with the object of securing co-operation in promoting the sale of honey, and showing the most modern methods of producing it in its most attractive form at exhibitions held for the purpose. Nearly the whole of these county societies affiliated with the central association, paying an affiliation fee yearly, and receiving in return the silver medal, bronze medal and certificate of the association, to be offered as prizes for competition at the annual county shows. Other advantages are given in connexion with the qualifying of experts, &c., while nearly all the county associations in the United Kingdom employ qualified men who visit members in spring and autumn for the purpose of examining hives and giving advice on bee management to those needing it. Another advantage of membership is the use of a "county label" for affixing to each section of honey in comb, or jar of extracted honey, offered for sale by members. These labels are numbered consecutively, and thus afford a guarantee of the genuineness and quality of the honey, the label enabling purchasers to trace the producer if needed. The British Bee-keepers' Association is an entirely philanthropic body, the only object of its members being to promote all that is good in British bee-keeping, and to "teach humanity to that industrious little labourer, the honey-bee." Bee-appliance manufacturers are not eligible for membership of its council, nor are those who make bee-keeping their main business; thus no professional jealousies can possibly arise. In this respect the association appears to stand alone among the bee-keepers' societies of the world. There are many equally beneficial societies, framed on different lines, existing in Germany, France, Russia and Switzerland, but they are mainly co-operative bodies instituted for the general benefit of members, who are without exception either bee-keepers on a more or less extensive scale, or scientists interested in the study of insect life.
The bee-keepers' associations of the United States, Canada and most of the British colonies, are--like those last mentioned above--formed for the sole and laudable purpose of promoting the business interests of their members, the latter being either bee-farmers or bee-appliance manufacturers. Thus they make no pretension of any but business discussions at their conferences, and much benefit to all concerned follows as a matter of course. In fact, we find enthusiastic bee-men and women travelling several hundreds of miles and devoting time, money and labour in attending conferences of bee-keepers in America, while the proceedings usually last for several days and are largely attended. The extent of the industry compared with that of Great Britain is so great that it fully accounts for the difference in procedure of the respective associations.

The bee-appliance trade.
As a natural consequence of this activity, the trade in bee-appliance making has assumed enormous proportions in the United States, where extensive factories have been established; one firm--employing over 500 hands, and using electric-power machinery of the most modern type--being devoted entirely to the manufacture of bee-goods and apiarian requisites. From this establishment alone the yearly output is about 25,000 bee-hives, and upwards of 100 millions of the small wooden boxes used for holding comb-honey. The most generally approved form of this box is known as the "1-lb. section," made from a strip of wood 1/2 in. thick, 2 in. wide, and of such length that when folded by joining the morticed and tenoned ends A B (fig. 10) it forms the section of box C, measuring 4-1/4" X 4-1/2" X 2" when complete, and holds about 1 lb. of comb-honey when filled by the bees and ready for table use. The V-shaped groove D (cut across and partly through the wood) shows the joint when in the flat, and E the same joint when closed for use. All the section boxes used in the United Kingdom are made in the U.S.A or in Canada from the timber known as basswood, no native wood being suitable for the purpose.
