These, perhaps the most conspicuous of our native bees, certainly the largest, and probably the most generally known after the domestic bee, have their scientific generic name fromβόμβος, an imitative word, made to indicate the sound of the hum of the insects themselves. They have many popular names such as bumble bees, dumbledors, humble-bees, and in Scotland they are called foggie bees. They consist of three sexes, males, females, and neuters, which differ considerably in size, the females being very much the largest, and the neuters the smallest. Of course, individually, like all other insects, there is much variation among them in the intensity or diversity of the colouring of their pubescence, from which it is chiefly that they derive their specific distinctions; in the relative sizes of individuals also there are great differences. It is the males, as is usual among the bees, which are the gayest in their attire, and take the widest range of variation, and sometimes so much exceed the typical specific character in their markings as to require experience to identify them, and to place them correctlywith their true species, which can only be ascertained with certainty by the examination of the male organs of generation, which differ in the various species, but are undeviating in their specific uniformity. Of this character, which I was the first to discover as being of specific value for critical determination in the separation of the species of very difficult insects, I was enabled to make important use in the genusDorylus, in a monograph on theDorylidæ, an exotic family proximate to the ants, and which was published in Taylor’s ‘Annals of Natural History’ for May, June, and July, 1840. The females and neuters ofBombusare less subject to such extensive dissimilarity, and may be usually associated, by their pubescence, in their legitimate groups. Form also frequently lends its aid as subsidiary to their specific identification.
These andApis mellificaare our only social bees, which live in numerous communities under a kind of municipal government which is considerably less perfectly organized in the present genus than in the domestic bee, and thence they are called “villagers,” in contradistinction to the citizenship of the hive bee, earned by its comparatively metropolitan institutions, and the centralization of its government, which wholly emanates from the pervading influence of the queen upon the labours, and, indeed, upon the existence of her subjects. But theBombiare under much less social restraint, and admit of several co-regents in the same community, without its being productive of any disturbance of social harmony. In the account of the genusApathus, the last described, we have seen that theBombiare subject to bee-parasites, which in some closely resemble the species they infest, and we have also shown there how these are distributed. The hive bee is not exposed tosuch intrusion, although, like these, they have many enemies. In the very earliest spring months theseBombiare abroad; for as soon as the catkins of the sallow are ripe for impregnation, they are on the wing. But it is now that the large females only are at work, for they have to create their companions before they can be surrounded by them. Their fruition is the result of the previous autumn’s amours, at a period too late to form sufficient stores for the numerous brood they will produce, and accordingly, after revelling in a brief honeymoon, they resort, like staid matrons, to a temporary domicile, some cavity just large enough for themselves. In this retirement they pass the cheerless wintry months, requiring perhaps the incubation of time thoroughly to mature their fruit. Whether this be the case or not, as soon as the earth begins to feel the warmth of the sun upon its return from its far southern journey, and to respond to the renewed vitality it gives to vegetation, these bees feel its active influence and come forth. With the progress of the spring and summer most flowers are exposed to their rifling, but they revel upon the elegant flowers of the Horse-chestnut, and their hum is the music of the lime when it is in blossom. According to the species, they select a cavity for their nest, or construct it upon the surface of the ground, this being the case with theCARDER-BEES, which gather moss to construct their residence. In those which inhabit beneath the surface, the selection of an already formed cavity greatly abridges their labour, and their instinct prompts them to choose one sufficiently large for the prospective community, but the nest itself is gradually extended in size suitable to their progressive increase in numbers. All that the parent female does at first is to form areceptacle sufficiently large for her first gatherings of pollen and honey, whereon to deposit her first eggs, and to form a waxen cruse or two to contain the honey requisite for the nest operations of keeping these masses moist enough for the nurture of the larvæ. The material of these pots although called wax is not properly so, but is an agglutination of collected vegetable matter, for it is not plastic to the fingers like wax, and it burns, leaving a carbonaceous residuum very attractive to moisture. The larvæ hatched from the eggs now deposited produce the first neuters, which spin a cocoon wherein they rapidly undergo their transformations. They are, in the first instance, aided to emerge from their silken cot by the parent gnawing off its top, but subsequently this duty is performed, as the family increases, by the neuters then developed. The young bee, on emerging from its cocoon, is not thoroughly hardened in its integument, and its pubescence also acquires by degrees only its proper colouring; all this is not long in being effected, but, until they are thoroughly able to fly forth, they continue to be fed by their elder sisterhood, for the neuters are properly abortive females. Males, and further productive females are produced later in the spring, and are smaller than the normal sizes of those sexes; the autumnal brood, consisting also of males and females, again resume the full size of the complete insect, and it is these females which, after impregnation, hibernate and reappear in the following early spring to be each the parent of a new progeny. The population of these nests varies considerably in the several species: in some, as in that ofBombus terrestris, there are more than two hundred, and in that ofB. senilisthere are about a hundredand forty; but it is in those that construct their nests above the ground that the fewest are found. As with the general population, so with the relative proportions of the sexes, the several species vary. Of course all these numbers are approximative only, as under certain conditions they will necessarily differ, nor are the general or relative numbers identical, even in the same species, in the same season, and in the same locality. The proportions are usually somewhat like this, about double the number of neuters to females, and nearly the same number of males as of females. In some of the communities there are even as few as twenty neuters, and these, of course, comprise those species which are most rarely found by collectors. The most pugnacious of all, and the fiercest in their attacks and most painful in their stings, are those which live underground or in cavities formed of accumulations of stones, and it is these which are the least constructive in their habitations, as if their truculent nature rejected the concomitants of incipient civilization; for it is those which build moss-nests, requiring a certain amount of skill, that are the most gentle in their habits. With the increase of numbers in the habitation, the rapidity of the labours progresses, and the accumulations quickly increase; but there is always opportunity for the entire community to find employment, either in enlarging their nests, when they build them, or in securing them from the intrusion of water, or repelling enemies, or feeding the young, and accumulating stores. In collecting pollen they are often covered as if they had rolled themselves in it, and this they brush from their hairy bodies chiefly with their posterior legs; sometimes they return in this disguised condition, and free themselves from it only at home; inother cases they bring it home collected in little masses upon the corbiculum, or basket, of the posterior shanks. They may be often caught thus laden, and I once captured a large female ofB. terrestris, with the shanks and plantæ of both intermediate and posterior legs covered with masses of thick clay, required doubtless at home for some domestic repairs. The instinct of these bees teaches them that where the tube of the flower is too narrow for the introduction of their body, and too long for even their long proboscis to reach the nectarium at the bottom, they may get at the honey by piercing a hole near that organ, which they know where to find, and thus they readily get at the treasure that they seek, lapping it through the aperture and carrying it off. If, in their collecting excursions, they are intercepted by heavy rains, or loiter far away too long until the twilight closes, they will pass the night away from home, and return laden with their gatherings as soon as the warmth of the sun reanimates them to activity; thus they will often sleep in flowers, and a nest therefore taken at night is not always a sure indication in those found within it, of its complete population. In their amours, the autumnal females evince considerable coquetry to attract their partners: they place themselves upon some branch in the most fervid sunshine, and here they practise their cajoleries in the vibrations of their wings, and allure them by their attractive postures. The males are simultaneously abroad, and soon perceive them. The seduction is complete, and they pounce down upon them with impetuosity, but their brief indulgence terminates in death, for with his abating vigour the female repulses him, and he falls to the ground never to take wing again. Amongst their insect enemiestheDipterousgenera,VolucellaandConops, are very destructive to their larvæ,—the first of these genera in its colouring greatly resembling the species upon which it preys. Foxes, weasels, field-mice, all prey upon them, and, like schoolboys, often destroy the bee for the sake of its honey-bag, an instance of which I have before recorded as illustrative of their endurance of the loss of a considerable portion of the body without its being fatal.
The most interesting part of their history is perhaps that upon which I have not yet enlarged, namely, the structure of their nests. This is particularly the case with the carder-bees, which felt and plait the filaments of moss to form its whole enclosure. Such species select a spot close to an abundant supply of the material; this they bite off and form pellets of. To these nests a moderately long arched passage is formed of the same material, of sufficient size to permit the free passage of the bees to and fro. This necessarily is shorter at first and leads to a smaller receptacle when the parent bee works alone. But as her offspring of workers increases, the passage is lengthened and the nest enlarged. To construct it, when in full activity, the bees form a chain, one behind the other, extending from the growing material to the entrance of their passage to the nest, all their heads being turned towards the moss and their backs to the nest. The first bites off the raw material, rolls it and twists it, and passes it to the second, by whom and the succeeding ones it undergoes further manipulation, and where the chain terminates at the commencement of the passage another bee receives it and conveys it along this into the interior, and then applies it itself or passes it to others thus employed where it is required.A vaulted covering and sides is thus formed or extended within the cavity by the plaiting or wreathing together of these sprigs of moss, and the inside of which is further strengthened by being plastered with a coating of the pseudo-wax, which, however, smells much like true wax, and with which the lower loose filaments of the moss are intermingled, that one cannot be separated from the other without tearing the whole to pieces. Thus ingeniously do these insects enclose their home. These nests are not always on the surface, but often cavities of the necessary size are thus lined, and then they are doubly secure. Within these nests, with the increase of the population the number of the cocoons of course increases, as they are never used twice over, excepting that when they are conveniently situated for the purpose they are converted into honey pots. Thus sometimes several layers are formed of these irregularly-placed cocoons, of which the longest diameter is, however, always perpendicular to the horizon. In this wayB. muscorum,senilis,fragrans, and others build. Some use a naked cavity, and merely secure it in its crevices from the filtering intrusion of rain or other water, the closing patches being formed of the usual waxy material. This is the practice ofB. terrestris, which associates the largest communities of all; andB. lapidariusseeks cavities among stones or in the earth, and forms a nest of a regular oval, but merely clothes the sides, which is done by bits of moss and grass carried carefully home. The domestic arrangements within are much the same in all, the prolific females and the neuters being the labourers, which perform all the duties of building, the collecting and caring for the young, the function of the males being limited to the perpetuation of the species.

GENERAL OBSERVATIONS.
The name of this genus,Apis, adopted by Linnæus as the classical generic name of the bee, although with him it comprised the whole modern family of these insects, but which, as now restricted, in accordance with its limitation exclusively to the congeners of his adopted type, is the ancient Latin vernacular name of the honey-bee, and to which it has been ever since uniformly attached. This name, as shown by its derivative meaning, was originally imposed with direct reference to the insect’s constructive habits, as was the case with the names given to it in the more primitive languages before referred to, and which is also the origin of its Teutonic and Scandinavian appellations—Biene,Bie, andBi, whence our own common name for it is obtained through the SaxonBeo, and we have beside Bye or bee, signifyinga dwelling. From this circumstance it would seem that a very early and universal discernment existedof its ingenuity and skill, its significant name being everywhere analogous.
The habits and economy of these industrious little creatures have been a source of greater wonder and admiration the more closely and accurately they have been observed. They have attracted the thoughtful speculation of minds of the largest compass throughout all ages, which, reasoning upon themodus operandiof these insects, have endeavoured to define, and determine the differences between instinct and reason, with their precise limitations. But baffled in their attempt to settle whether these be affinities or analogies, it should rather have persuaded them to adopt the motto of Montaigne, and exclaim,Que sais-je?Into these metaphysical discussions it is not necessary to enter, and I confine myself to the natural history of the insect.
Although the description of the three sexes which comprise the population of the hive are technically given above with scientific precision, it will be as well, perhaps, to recapitulate them briefly, with their distinctive attributes, in a more popular form.
They consist of a queen, or productive female, whose function is thought to be exclusively to lay eggs, but who may perhaps have some hitherto undiscovered control over the executive of the hive, to be implied by the confusion invariably following her death or her removal from the community, and which becomes totally destructive to its organic constituency unless stayed by another monarch being improvised, or by one extraneously supplied; one monarch alone rules without a coadjutor, and without any equal being tolerated, for the presence of a second queen, or the immature larva of one, even of her own progeny, maddens her to murderous aggression,or to the impulse of emigration accompanied with a host of adherents. She never leaves the hive when once her duties have fully commenced, for by distinction of structure she is rendered incompetent to execute any of the labours that devolve upon the workers; her tongue is formed only to lap nutriment; she has no cysts for the secretion of wax, she is without the honey-bag for conveying that liquid home, and her posterior shanks are convex externally, and thus deficient in the concave basket for carrying home the stores of pollen or propolis, whilst their plantæ are without the little earlet at the top externally, or the close dense brush arranged in rows within, which aid these workers in their many manipulations. Her wings are too short to convey her ponderous body through the air, and her sting becomes stronger by being curved. Thus she is exonerated from labour by the incapacity of her structure to execute it, although her duties are quite as incessant and as arduous, being indispensable to the perpetuation of the species.
Her consort, theDRONE, is the male of the hive, and although the queen is monandrous or single-spoused, and although the hive during the season rarely throws off more than three swarms, usually restricted to the accompaniment of a single queen, and thus but three males are absolutely required, nature is so provident of the great design of perpetuation, that to provide against the possibility of its frustration, the hive usually produces about a thousand drones. A peculiarity in the structure of the drone which facilitates his discovery of the virgin queen when she issues from the hive on the bridal excursion, which she makes preliminary to her heading a swarm of emigrants, or assuming monarchyat home, consists in the vertical enlargement of his compound eyes, which meet over the brow, and in the posterior expansion of the inferior wings, which take a broad backward sweep, giving the insect larger powers of flight, but perhaps required as much by its own bulkiness and weight as for the purpose of ascending above his bride in the upper regions of the air; but that its weight cannot be the sole reason is testified by the analogous structure in the male of the genusAstata, one of the fossorialHymenoptera, where a similar expansion of the inferior wing is concomitant with a similar development of the compound eyes, yet in which the abdomen is very small, and this power is therefore evidently given to these merely to increase the velocity or the duration of their flight. The rest of the structure of these drones disables them, like all other male bees, for any labour; and as they must be sustained as long as they may be of service, the possibility of which terminates with the last issue of a swarm from the hive, a period appreciated by the instinct of the workers, they are then driven forth, but it is in dispute whether the workers destroy them, or whether their destruction is effected by exposure and hunger, or by the natural limitation of their lives, for although their tongues are formed upon the same type as that of the worker, it is considerably less developed, and appears to be adapted only to obtain nutriment from the honey already collected in the cells, as they seem even deficient in the instinct to gather it for themselves from flowers, never being observed to visit them.
The last inhabitant of the hive is theWORKER, or abortive female, whose labour has several phases. A difference of size amongst them has been supposed tohave been noticed by observers as varying with their occupation and duties, but as they are all constructed in the same manner, with precisely the same organs, which are of the same form and in the same situation, this must be a mere imaginative surmise. Their similarity of structure permits them, collectively, to apply themselves to the same occupations which the needs of the community may at any moment demand. Taking them separately with their distinctive occupations at any given time, without implying by it a permanent separation of classes, we find them to consist of wax secreters, builders or cell-sculpturers, honey collectors, pollen collectors, propolis collectors, nurses of the young, ventilators, undertakers to carry off the dead, who are perhaps also the scavengers which cleanse away any occasional dirt, sentinels to guard the hive outside and inside, and attendants upon the queen, or as the “‘Times’ Bee Master” very aptly designates them “ladies in waiting,” and at all times many slumberers are reposing from their toils. That all these duties are transferable, and consequently are transferred indifferently from one to the other, is implied by their general capacity for fulfilling them resulting from this identity of structure, which will be understood as not at all infringed by the separate capacities I unfold as devolving from their temporarily limited functions, all being simultaneously in action, but distributed amongst the several individuals.
The first important occupation of the worker is the secretion of wax for the structure of the cells, and, to effect this, honey must be collected, for it is solely from the digestion of honey that the wax is produced. This in due course passes from the first stomach or honey-pouchwherein it is collected, thence to the second stomach, and then on to the cysts or little bags which run along on each side from the second to the fifth ventral segments, and correspond and communicate with eight trapezoidal depressions placed externally upon the plates of the ventral segments—four on each side, through the concavity of which the secreted wax exudes in a liquid, transparent, hot state, forming a thin scale within each, which the air hardens into a white substance, as the pulp of paper is hardened upon the form into which it is introduced, or like salt crystallizing into flakes from sea-water in shallow salines. This, however, is not yet wax, although its essential constituent, but to become so these scales are removed by the scopulæ of the posterior plantæ and their auricle, to the intermediate feet and by these transferred to the anterior pair, which pass them to the mandibles, where they are masticated and mixed with a saliva issuing from the mouth, and thus intermingled they consolidate into a white opaque mass, which issues from the mouth like a thin strip of riband, and constitutes true wax, plastic to their manipulation. To form this secretion, the bees having collected the honey themselves in the first instance, or having consumed sufficient before leaving the hive with the swarm, but which they subsequently obtain from the supplies stored in the present hive, hang themselves in festoons in all directions about its cavity, each festoon being formed by two parallel chains of bees clinging together; the top bee on each side hangs by its anterior claws to the top of the hive, and the next in succession grasps with its fore claws the hind claws of that and so on, until the depth of the festoon they find to be sufficient, when the bottom bees of each chain swingthemselves together, and cling to each other in the same manner by their hind claws only. These festoons are speedily suspended, and with a fresh swarm are in immediate active operation. The secretion requires about twenty-four hours to complete, and as this is accomplished the festoons break up, and these secreters convey it to where the sculpturer bees or builders are moulding the cells, to whom it is successively supplied by the secreters themselves as wanted, for none is stored, although the wax of old or dilapidated parts of the hive, or of the vacated cells of the new-born queens are reconverted to use. These builders are very rapid in their construction of the hexagonal cells, which, as they are progressively completed, are stored with honey, this being during the time assiduously gathered by the honey collectors, and these cells are interspersed occasionally with those wherein pollen or propolis is stored, each of which, as the bees collecting them successively return, is cast into the selected cell by the bee collecting it, who returns at once to the same employment, whilst the store thus deposited is immediately compactly pressed in and warehoused by other bees who fulfil that duty, or who cover it in when the cells are filled, with a waxen covercle formed of concentric circles; or, in the case of the honey-cells, to keep the thickened operculum deposited upon it in due position and repair, after the retiring of the bee which brought home the fresh store of honey, and which had displaced it to regurgitate her addition into the cell. This operculum or cover is of a thicker consistency than the honey itself, and prevents its oozing from the cells, which would often take place from their uniformly horizontal position, were it not for the sagacity which prompts them to introduce this preventive,and which is not removed until the cell is filled; it is then covered hermetically with its waxen top.
A sufficient number of cells being ready, and sufficient stores of honey, pollen, and propolis for the progressive labours of the hive, and a great number of empty cells all finished for the use of the queen, she begins to lay her eggs. As these are hatched the duty of the nursing-bees commences, which is to feed the young, who crave for food like young birds, and are as diligently supplied by these nurses with a material called bee-bread, which consists of masticated pollen, the pollen being exclusively stored and used for the purpose. This is mixed with some secretion from the mouth, which converts it into a sort of frothy jelly. These bees are never negligent of their duties, and with their feeding the larvæ rapidly grow.
To keep up a necessary supply of air in the hive, and to prevent suffocation from heat, a certain number of the community are employed in fanning the passages between the cakes of comb and the whole interior of the hive, by the vibration of their wings, which thoroughly ventilates it, and the accumulation of deleterious air is prevented; some, for this purpose, being posted at the aperture to the hive, where, this vibration causing a temporary vacuum, the external air rushes in, and the chain of succession of bees within becoming thus vibrating air-valves completes the ventilating arrangement. While all these operations are progressing, a certain number are acting as a militia of citizens, who have substitutes only in the succession and change of duties. These act as sentinels, who guard the entrance and patrol the interior and courageously intercept all inimical intrusion, for the bees have many enemies, but who are merely so to benefit themselves, and are not parasites of the natureof the bee-parasites of the solitary kinds; and where they cannot individually avert it, they obtain collateral aid from others of their staff. The next class is the attendants upon the queen: these vary in number from twelve to twenty; they invariably accompany her wherever she proceeds throughout the hive, for the purpose of laying her eggs; and whether their custom gave rise to the etiquette which attends human royalty, that a subject may never turn the back upon the sovereign, these attendant bees surround her with the head always turned towards her, and seem to caress her with their antennæ and pay her every kind of deferential homage, those in front moving backwards as she advances, and those on each side, laterally, so that they ever face her; and as they tire others succeed them in their duties. Another set fulfil the office of keeping the hive thoroughly clean, for the transit of such large numbers will inevitably collect occasional dirt, as will the drift of the wind at the entrance of the hive and the action of the ventilators themselves. Their duty it is also to remove any extraneous organic body that has forcibly entered and which may have succumbed to the vindictiveness of the bees. Where they are not strong enough, even collectively, to effect the removal, as in the case of a mouse or anything else as large or larger, they then call to their aid the wax workers and the repairers; these enclose the obnoxious body, which they have the judgment to know will become dangerous from putrefaction, to aid in its prevention, by a cerement of wax or propolis, which prevents any offensive exhalation, and thus secures the wholesomeness of the hive.
Here is completed, with the enumeration of those which successively repose from their toil, the several labours of the community which inhabits the hive.
The structure of the workers, which enables them to carry on all these operations with the requisite facility, is very different from that of the two sexes we have just described. As before said, they are abortive females, but, as I shall have occasion to explain lower down, capable of having this special incapacity removed, if the necessary process requisite to be adopted for the purpose be applied within three days of their being hatched into the larva state. The acquisition of the faculty of fertility entails, however, the loss of all power of pursuing any of the other occupations of the hive practised exclusively by the workers in general. The nurture that gives it them converts them into queens, and moulds them to the structure of this sex described above. As a remarkable and rare exception, some one or other of these workers will occasionally have power of laying a few eggs, but which are always those of drones. The other peculiarities of their structure are its adaptation to the secretion of wax above described; and their power of throwing up the honey they have collected in the first stomach or honey-bag, before it passes on by digestion, somewhat in the way the ruminant quadrupeds bring up the cud, of course by muscular action, without the convulsion of vomiting. Their next distinction is that their mandibles are edentate and more like spoons, and are often so used, or as the plastering-trowel of masons is for smoothing surfaces. Their legs remarkably differ from those of the other sexes, all of their limbs being somewhat adapted to the collection and conveyance of pollen and its manipulation, as well as that of propolis; but it is the posterior shanks which are specially constructed for the conveyance of these materials, by being framed externally like a little basket; beinghollowed longitudinally and their lateral edges fringed with recurved hair, which retains whatever may be placed within the smooth and hollow surface, and the apical extreme edge has a pecten or comb of short stiff bristles. The first joint of the posterior feet have also their distinctive form, adapted to special branches of their economy. These are oblong, wider than the shank, and about two-thirds its length, and consequently powerful limbs; at the outer angle of the edge, nearest the shank, is a little projection called the auricle or earlet, the inner surface is clothed with ten parallel transverse rows of close dense hair, and its apical edge has along its whole width a pecten similar to that of the apex of the shank. This shank being without spurs, which only the domestic bee is deficient in, gives the pecten a freedom of action it would not otherwise have, and enables it to be used together with the earlet opposite to it on the foot, as an instrument for laying hold of the thin flakes of wax upon the venter, and to bring them forward to the intermediate legs to be passed on to the mouth, and there to be converted into wax. The pecten of the foot and also its brush aid in their removal in case of need, and help as well both in the manipulation and the storing the materials collected. Thus, this whole structure, exclusively possessed by the worker, is pre-eminently designed for the manifold operations of the hive; and the bee itself and its works are but one closely linked chain of wonderful contrivances.
The entire economy of the hive seems to emanate exclusively from the two most prominent attributes of instinct, that of self-preservation, and that other more important axis of the vast wheel of creation, the secured perpetuation of the kind by the conservativeστοργὴ, orabsorbing love of the offspring. The latter is more eminently developed in the social bees than in any other group of the family of these insects. In the solitary bees it presents itself as a blind impulse, unconscious of its object; for did we admit the consciousness of the purpose of their labours, we should evidently endow them with reason. How could they know, without reflection, that the food they store in the receptacle they form for the egg they will deposit, and which receptacle is exactly adapted to the size that the larva which will be hatched from it will take, is to nurture a creature they will never see, and whose wonderful transformations they will not therefore witness? In the hive bee the maternal instinct exhibits itself as an energy diffused through a multitude of individuals, but these witness the results of their solicitude, and exclusively promote its successful issue; and in these also the instinct of self-preservation is a diffused impulse, which likewise includes the preservation of the society.
As male and female conjunctively make up the species, thus do the queen-bee and the neuters collectively make up one sex,—the mother,—for the functions performed by the female alone in the case of the solitary kinds of bees are, in the genusApis, separately executed. The cares and labours of maternity devolve upon these neuters, while the queen-bee’s maternal function is limited to merely laying the eggs with which she is replete, with the instinctive power of selecting for them their proper depository,—each of which is adapted in size to that of the sex which will be produced. Her maternal instinct stops abruptly here, without the development of an afterthought or care for their future thriving. The instinct of the neuters, like the anticipative promptings of thehuman mother, to prepare the clothing and other necessaries for her expected infant, has forecast the queen’s needs in its intermittent urgency, by progressively constructing cells fitted severally in size for the growth and nurture of neuters, the first developed; of drones, the next produced; and lastly, of queens, which soon afterwards appear; she instinctively knowing the proper time and the suitable use of them, having the faculty of distinguishing them with a view to the deposit of the particular kind of eggs of which she is for the moment parturient.
The drones, or male bees, appear to receive life for one substantial purpose only, which is soon accomplished, but during the short space of time its successive performance requires, it is incidentally accompanied with assistance to the general community whilst they remain permitted occupants of the hive, by aiding in heating and ventilating it,—a labour repaid by the food, which they obtain from the stores kept open for daily consumption. Although uncontributive to the acquisition of the riches of the hive, yet are they indispensable to the perpetuation of the species, and their murder as supposed by some apiarians, or their expulsion as thought by others, in either case equally terminating in their destruction, seems an unworthy return for the important service performed, although this is restricted to the number of individuals required by the equal number of queens that may be produced. To this number their production might be limited, but for the chance of either or all of these queens failing by some casualty to obtain a prince consort. To baffle the possibility of this mischance, a very superfluous number of these drones is hatched, as above stated, which are on the alert, wheneach queen successively issues forth upon her bridal morn, to catch her favouring glances, and be the accepted groom. That they are not further conducive to the well-being of the hive is the fault of their structure and of their instinct, which are correlative, they being as little fitted either in their tongue or their legs for the uses of the hive as the queen herself. The physiology of their intercourse is a mystery of mysteries, and would seem to partake of the principle, modified, of that developed in the aphides, where the vital power passes on through successive generations by the efficiency of the energy of one ancestral intercourse. In the hive bee this is not the case, but in these the one espousal fertilizes eggs to the number of often a hundred thousand, yet undeveloped and even indiscernible by the aid of the microscope in the ovaries of the queen, and which become bees progressively in the course of a couple of years, the supposed duration of her existence, during the whole of which time she is laying. The accepted male is destroyed by the effects of the amour, and when all the queens which are to be the heads of independent communities are successively fertilized, and have led forth their colonies, the remaining drones issue compulsively from the hive and are lost in the wideness of nature, and die by the natural limitation of their existence, or become the prey of their numerous enemies.
The neuters or workers are, as it were, emanations of the queen, or the organs whereby her several functions as a mother are performed, considering the species as restricted to two sexes, and thus they comprise with her, collectively, one organic whole. That this is a consistent view of their condition is further proved by the circumstance that from their larvæ, upon the failure of a queen,a new queen is produced upon one being supplied with a certain nutriment that developes the capacity that would remain inert and abortive, were it not thus promoted from its primary state. It may be questioned whether the eggs deposited by the queen in the royal cells are other than neuter eggs, their subsequent nature being changed by the different quality of the sustenance they are fed with when hatched, as is the case in the above noticed defection of a queen. This then would limit the queen’s eggs to the eggs of neuters and of drones, thus further corroborating the idea of the existence of but two sexes.
I have stated above the supposition that the queen’s office may be restricted to the laying of eggs, but it must be inferred that it has a wider compass, and possibly comprises some administrative function in the regulation of the hive, from the circumstance that with her loss the entire community loses its self-possession and self-control. Labour then ceases and the hive becomes the scene of turmoil and confusion, and unless the loss be repaired in the way named above, which their instinct teaches them to adopt, if any eggs have been already deposited, or if supplied by the surreptitious introduction of another queen which they immediately raise to their superintendency, paying her the same deference they had done to their lost monarch, or would do to a legitimately native birth, it disperses and destroys the community. Such a loss in its natural course must necessarily, to be effectively repaired, take place in the interval after the laying of the drones’ eggs, and before those of the queens are deposited, for otherwise she would remain unimpregnated. Having thus shown reasons for supposing that the hive actually contains but two sexes, and having alsoshown that the first phase exhibited of this distributed maternal instinct by which the neuters form conjunctively with the queen a many-headed and many-hearted mother, is their preparation of the cells for all the purposes required,—the next and most important, and the one perhaps which elevates them vastly higher in the scale of social intelligence and affection, is the absolute development in them only of maternal solicitude for the well-being of the offspring. This certainly proves the existence of the diffused maternity urged, for they feed the hatched young as the bird does its callow, from hour to hour, and which, when full grown, they enclose in its formative cell, to undergo its changes and become one amongst themselves. It is not absolutely determined whether the functions performed within the hive are restricted to distinct sets of the workers, but it may be presumed that the duties are transferable, for the most plausible supposition is, that all the offices are interchangeably performed by the entire population, possibly merely limited to daily alternation of individuals taled off each morning for the day’s duties. That an administrative regulation must exist under some executive authority, emanating doubtless from the centralization of all in the queen, and communicated to the rest by her relays of attendants, may be conclusively inferred, otherwise all might similarly employ themselves from day to day, and thus overwhelm with one work the multiplicity of labours required for the well-being of the hive. For whilst some are secreting the wax from the honey they have consumed, others are moulding it into shape, others are harvesting the bee-bread to feed the voracious larvæ, others are gleaning the propolis for the security of thedomicile, others are collecting honey to store as needful supplies, others are either ventilating or heating the interior, others act as sentinels and guard the approaches or patrol the passages within, and will die in that defence like genuine patriots, and others are in attendance upon the queen in her progresses through her dominions, and who may individually act asaides-de-campto convey her commands to the rest. All these are not fanciful embellishments of the narrative, but substantial and well-authenticated facts, supported by the repetition on many sides of careful observations, but perplexing to human intelligence, for not the least wonder of this conventicle of wonders—the hive—is that it confounds the astute reason of man to comprehend it in all its significancies.
The first necessity of a new colony is the selection of a locality for habitation, which is usually effected by preliminary trustworthy intelligencers determining upon a site suitable from its concurrent conveniences. A sufficient supply of sustenance must be conveyed by the emigrants to accompany the preparatory construction of the settlement, until land can be cleared, grain grown, etc., and a year at least will pass, even under the most favourable circumstances of the exertion of the greatest industry, concurrently with the most propitious succession of the seasons, before it can become self-sustaining. But when once the wheel is fairly on the move, round it spins without interruption or relaxation. The colony thrives, increasing rapidly in its population; and where all have put the shoulder to the wheel it climbs the steep and rugged hill of prosperity, whilst those who are carried onward by its evolutions, from each of the many successive terraces of this noble height, survey a broad, cheerful, and fertile landscape, extending itself with theirelevation, spread out to a distant horizon, which many of the more venturous spirits amongst them, urged by the teeming increase of their compatriots, have already traversed, and who themselves are now rejoicing in the establishment of offshoots, which speedily rival, in successful fruitfulness, the wide-branched productiveness of the parent stock.
This is strictly the history of the hive, and the parallelism is complete, even to the conveyance with them of the preliminary needful stores. Before a swarm issues from the hive, some fly forth to select a dwelling-place, and return, it is presumed, to make their report.
The population of the hive becoming so dense that there is no longer room for the free and unrestrained circulation of the ordinary processes of the community, and so hot from the inconvenient accumulation of such numbers,—for they extend sometimes to as many as fifty thousand,—instinct prompts a portion of the community to migrate. This disposition is further promoted by the progressive, or completed development of some of the young queens. The inveterate and internecine animosity of these—anticipated rivalry, suggesting, it is surmised, the murderous desire, but being prevented from its indulgence by the defensive guardianship of several of the workers—urges the old queen to abandon at this conjuncture her royal metropolis. The inclination to do so, it would appear, is already foreseen by a very large body of her subjects, for if her departure be delayed by her successor’s protracted incapacity for undertaking the sovereign rule, the intending emigrants, having already abandoned all the labours of their old domicile preparatory to their issuing forth, will cluster in groups about the bee board until she is ready to emerge.This condition will sometimes last a day or two, and thence of course all is confusion both within and without the hive, for her subjects have suspended their labours and she has suspended her egg-laying, and roams wildly about within, striving, whenever she approaches a royal cell, or a fully developed young queen, to attack the latter, and destroy her by stinging her to death, or, to tear the former to pieces to get at the imago within, which indicates its apprehension by a shrill piping sound. But she is forcibly dragged back from this apicidal purpose by the working bees which surround each, and who now intermit their usual deference to prevent this destruction, and bite her and drag her back. The future queen of the abdicated throne having, during this turmoil, returned from her wedding tour, and being still protected from slaughterous aggression, the old queen indignantly issues forth. This exodus takes place usually on a brilliant and warm day, between twelve and three,—accordingly during the hottest hours. This is the first swarm of the year, and if the season be very genial it will take place in May. In this migration she is accompanied by all her most faithful lieges, which comprise, to the honour of beehood, by very much the largest majority of the inhabitants, to the number usually, in a well-stocked hive, of several thousands,—say from ten to twenty, depending on the population of the hive.
Having thus issued forth in a body, they shortly alight upon and about the branch of some adjacent tree, clustering, in as close proximity as they can, to their royal leader. In a natural state, when duly organized to proceed, they would thence start for the domicile that had previously been selected by the emissaries above noted;but, as their natural habits are not at all perverted by their subjugation to man, we will pursue their history under his dominion. This will be the more convenient, for in the comfortable hive to which they have been transferred by his agency, we shall have every opportunity of exactly watching their manœuvres by the facilities yielded in its being glazed for the purpose. We shall thus be enabled to see and follow the wonderful economy of the hive and its many mysteries, which it would not have been possible to accomplish in an abode of their own choice,—some cavity presented by Nature herself, the hollow of a tree, or an excavated rock. They are, therefore, now housed, and after the survey of the capacity of their abode, which is a short affair, with all the prompt energy peculiar to them they at once commence their labours. The queen is already matured, and ready to lay eggs. In a natural abode the gathering of propolis would perhaps be a first necessity to make their home water-and-wind-tight, for they abhor the inconveniences of the intrusion of wet or cold. It is with this material that they make repairs, fill crevices, and strengthen the suspension of their combs, which are hung vertically; and they apply it also to other purposes, which we shall see hereafter. This material is of a resinous nature, it has a balsamic odour, and is of a reddish-brown or darker colour, and is supposed to be collected from fir or pine trees, or from the envelopes of the buds of many plants, or their resinous exudations, especially that of the blossoms of the hollyhock. It is exceedingly clammy, and they have been observed ten minutes moulding it into the lenticular pellets in which they carry it home in the corbicula, or little basket, of the posterior tibiæ. They gather it likepollen with the fore feet, and pass it to the intermediate ones, whence it is taken by the posterior plantæ, kneaded into shape, and deposited upon the hind shanks. It dries so rapidly that often, upon arriving home, the bees which store it have much difficulty in tearing it from the legs of these collectors. The hottest days only are propitious to its gathering, for all moisture is injurious to it, and the hottest period of the day, also, is alone occupied in its collection. It is said that they have been known to fly as many as from three to five miles for it, from the circumstance that suitable plants were not to be found within a lesser radius; but this may be a mistake, for their ordinary excursions are not supposed to range wider than a single mile or something more, and bees may be able to find it where we may suppose it not to occur. In the abode with which we have provided them it is not so urgent a necessity, this being already wind-and-water-tight, although in the progress of their labours they find it indispensable, and use it to fasten the crevices that intervene between the bottom of the hive and the bee board, and, as before noticed, to strengthen the support of the cakes of comb which hang from the roof. The name it still retains is that which was applied to it by the ancients, and signifiesbefore the city, as indicative of its use in strengthening the outworks.
Conjoined herewith is the imperative need for the construction of cells for every purpose of the hive, namely, for the storing of the propolis, and that of the pollen, as also the collected honey, as well as for the reception of the young brood, for the mature queen is waiting impatiently to deposit her eggs. Simultaneously, therefore, is the wax being secreted and elaborated bythe processes previously noticed. The community is already late, and all are at once in active operation, but four-and-twenty hours must elapse before the cells can he commenced, for it takes that time to secrete the first batch of wax. Festoons, as before described, of these wax secreters are hanging in every direction within the cavity of the hive, and as soon as the process is completed by the first festoon, this dissolves itself by the several bees unlinking their feet, and a leading bee proceeds to the top of the centre of the hive, where she makes herself room from the lateral pressure of other bees, by turning herself sharply about and agitating her wings, and there she collects the scales from the surface of her ventral segments, manipulates them as before noticed, and thus converts them into wax. The rest follow her, and she collects it from them into a little oblong mass of about half an inch; whilst other bees from other festoons are continually arriving to deposit their produce; and as soon as the mass is sufficiently large, which is speedily the case, a sculpturer bee succeeds, and the first cell is laterally commenced. On the opposite side to where this is being framed, two other bees are at work, moulding the bottoms of two cells in apposition to the basis of the first one. The wax keeps constantly increasing by fresh deposits, and the rudiments of more cells are as rapidly formed. These all emanate laterally, in a horizontal direction or with a very slight incline towards their base. They gradually form the vertical cake of comb, for the bottom of one entire range of cells suffices for both sides and inevitably they are so adjusted that the bottoms of those on either side are each covered by one-third of the bottoms of each cell on the opposite side, and so conversely, receiving and communicating strengthby three thus supporting one. Here comes the great wonder of the hive; here in this fragile structure abides a mystery that has perplexed man’s keenest sagacity. Is it accident or is it intelligence that instructs the bee, or is it the impulse of the instinct implanted by that Supreme Intelligence which gives man his reason and moulds all things to their most fitting use?
Ray’s view is precisely this; he says:—“The bee, a creature of the lowest forms of animals, so that no man can suspect it to have any considerable measure of understanding, or to have knowledge of, much less to aim at, any end, yet makes her combs and cells with that geometrical accuracy, that she must needs be acted by an instinct implanted in her by the wise Author of Nature.” To support this idea of the geometrical skill of the bee, he cites “the famous mathematician Pappus,” the Alexandrian, of the time of Theodosius the Great, who “demonstrates it in the preface to his third book ofMathematical Collections.” “First of all (saith he, speaking of the cells), it is convenient that they be of such figures as may cohere one to another, and have common sides, else there would be empty spaces left between them to no use but to the weakening and spoiling of the work, if anything should get in there, and therefore though a round figure be most capacious for the honey, and most convenient for the bee to creep into, yet did she not make choice of that, because then there must have been triangular spaces left void. Now, there are only three rectilineous and ordinate figures, which can serve to this purpose, and inordinate, or unlike ones, must have been, not only less elegant and beautiful, but unequal. [Ordinate figures are such as have all their sides and all their angles equal.] The three ordinatefigures are triangles, squares, and hexagons; for the space about any point may be filled up either by six equilateral triangles, or four squares, or three hexagons; whereas three pentagons are too little, and three heptagons too much. Of these three, the bee makes use of the hexagon, both because it is more capacious than either of the others provided they be of equal compass, and so equal matter spent in the construction of each. And, secondly, because it is most commodious for the bee to creep into. And, lastly, because in the other figures more angles and sides must have met together at the same point, and so the work could not have been so firm and strong. Moreover, the combs being double, the cells on each side the partition are so ordered that the angles on one side insist upon the centres of the bottoms of the cells on the other side, and not angle upon or against angle; which also must needs contribute to the strength and firmness of the work.”
Each cell therefore is in shape a hexagon, that is to say, a figure with six equal sides, to each of which six other hexagons attach, for each wall forms also one wall of another hexagon. The basis of each hexagonal cavity is of an obtuse three-sided pyramidal shape inverted, and consisting of three rhomboidal plates, each forming one-third of the basis of the three opposite cells; thus the edges of these three basal plates of one side support three lateral walls of three hexagons on the other side. The inverted triangular pyramid thus made by these three equal rhomboidal plates, form, at one extremity and at each pair of their posterior edges a re-entering angle, and at the other extremity a salient angle. From these edges spring the lateral walls of the hexagonal cell, this shape being superinduced by the form of the edges ofthe basal cavity. That the bees should have been thus guided to elect a form which combines conjunctively the advantages of strength and capacity evidently proves that it is their instinct which guides them, which, being an afflation from the highest source, ensures the most complete perfection in its result. That it cannot be the effect of simultaneous lateral pressure is proved incontestably by the whole superstructure resulting from the design of the base; and this is further corroborated by the base of one cell on one side forming invariably equal portions of the base of three cells on the opposite side,—all clearly the result of preconceived design impressed upon their sensorium. From this combination of forms results the security procured to the fragile tenement, which consists of the very smallest quantity of material that will cohere substantially, for the bees are exceedingly parsimonious of their wax, as if the production of it were attended with pain or inconvenience, and it is only upon the construction of the royal cells that a profusion of this choice material is squandered. As soon as these cohorts of bees are in active operation, it is astonishing with what pertinacity and rapidity they labour, for within the space of four-and-twenty hours they will construct a cake a foot deep and six inches wide, containing within its double area some four thousand cells. Other cakes parallel to each side of the original are being at the same time carried forward with an interval between each sufficient for two bees to pass each otherdos à dos, and further to promote the convenience of traffic within the hive, and ready communication to its several parts, passages are left through these cakes from one to the other, so that the means of transit are opened, which of course saves much time. The queenis already making her progresses from one side of each comb to the other, and depositing her eggs as rapidly as she can, and is constantly attended by heraides-de-camp, as I have suggested, which act, as they evidently sometimes are, as the emissaries of her commands. They consist of ten or twelve or sometimes more, and have been previously described. They are replaced by others as they quit to obey orders, or as they retire fatigued, so that she is always surrounded. The number of eggs she will lay in a day is about two hundred. In doing this she first thrusts her head into a cell to ascertain its fitness, which having done, she withdraws it, and then curving her body she thrusts the apex of her abdomen, which tapers to the extremity for the purpose, into the cell, wherein by means of the sheaths of her curved sting, which act as an ovipositor, she places the egg at the bottom of the cell. It is possibly from some taction of this instrument that she discerns the sizes of the eggs, and thence their respective sex. This process she continues repeating, passing from one side of the comb to the other by means of the passages perforated through it, making the numbers as nearly as possible tally on each side and as opposite to each other as may be, and she will then go forward to further cakes of comb. In this way she lays about ten or twelve thousand in six weeks, depending much upon the propitiousness of the season, but the rapidity of this laying intermits according to the months; the above estimate is based upon what April and May produce, as it slackens during the summer heats and again revives in the autumn, but totally terminates with the first cold weather. She thus will lay from thirty to forty thousand or more in a year.
Apiarians do not state whether the same queen headsanother swarm on the following year, which perhaps she does in those cases of excessive fertility where her abundance is estimated at one hundred thousand, when by her sole individual capacity she populates three hives. In the more usual and ordinary case of her teeming with about seventy thousand, or fewer, she evidently heads but one swarm. With the described rapidity of the production of the cells, although the majority are store cells and not brood cells, conjunctively with her prolific laying, the population of the hive rapidly increases, which, added to the large original colony, will enable it in a propitious year to throw off a swarm of its own; but ordinarily she does not again lay drone eggs and royal eggs until the following season. The period at which to do this is taught her by the condition of the hive, as urgent for relief to its oppressive population by an exodus. The drone eggs are then laid, and are speedily succeeded by the laying of the royal eggs, so that the males of the season and the new queens may be hatched almost simultaneously, the drones slightly preceding the development of the queens. As soon as the egg of a worker is hatched, which, by means of the high temperature, is effected in four days after the laying, it, from its birth, is sedulously attended by the bees called nurse-bees. The little vermicle is very voracious and is heedfully supplied by these careful attendants, when it has consumed the quantity of bee bread already deposited in the cell by some of these nurses as soon as the egg was laid. This bee bread consists of pollen, taken from the cells by the nurses, where it is garnered for the purpose, being therein mixed with a slight quantity of honey. This, in masticating, the nurses intermingle with some secretion of their own, which gives it a sortof gelatinous frothy appearance, and upon this the young thrives so rapidly, greedily opening its jaws to receive it, that in four more days it is full grown, and fills the whole cell. The nursing-bees then cover this in with a light brown top, convex externally, and within it the larva spins for itself a cocoon to undergo its subsequent transformations. This cocoon is spun of a fine silk, which issues from the organ of the larva called the spinner, in two delicate threads, which, as they pass out, cohere together. It works at this labour for thirty-six hours, and then changes into the pupa or grub; thus it lies quiescent for three days, when it gradually undergoes its transformation into the imago, and it issues as a perfect insect about the twenty-first day after being deposited as an egg. The cocoon it has formed exactly fills the cell it has left, which still continues to serve as a brood cell until the succession of cocoons with which it is thus lined renders it too small for the purpose, it is then cleaned out by the scavengers of the hive and changed into a honey depository, but the honey stored in such a cell is never so pure as that which comes from the exclusively waxen cell. Thus is effected the transformation of the working bee, which, upon the very day of its emancipation from its nursery, commences its duties as an active member of the community, in the successive and several labours undertaken for the benefit of the commonwealth, and these it assiduously follows for the period of its natural life, which extends to about six or eight months.
The hive is now in the liveliest activity. The swarm which entered with the queen, and the large addition to the population which has already been produced from her incessant laying, are all at their several avocations.The whole hive, its entrance and the immediate vicinity, and far around is jocund with the bustle and the buzz of the busy little creatures going and coming; those returning are all laden, although some do not appear so, but these are conveying riches home within them, as they are returning from their excursions with their honey-bag well filled. There is welcoming recognition at the entrance to the hive, where, on its broad platform, they all alight, and there many are to be seen touching each other with their antennæ, or refreshing themselves by the vibrations of their wings, and in doing this they often raise themselves on the hind legs, or they are resting for a few seconds before they enter. Others are to be seen arriving unrecognizable from a coloured envelope of pollen which mantles them. The incessant hum that accompanies these proceedings is like the mildest tones of the surge of the distant sea, or the inarticulate buzz of the voice of large crowds. In this seeming confusion all obey the strictest order, for each attends to his own business only; there is no collision or loss of time or labour, each one fulfilling precisely its own mission. At this period the hive is a perfect model of order, neatness, and beauty. The combs we have seen so rapidly growing are to be filled, and fresh cells are being constantly constructed. The honey there stored from the gradual gatherings of these active harvesters is partly to be reserved for the winter’s needs, and is carefully husbanded, for each of these cells is, when filled, closed by a covercle of wax moulded as it is supplied to the operator in concentric circles, commencing at the edge, and each circle being completed before another is begun, and not in a spiral twist towards thecentre. To prevent the trampling of the discharging bees from injuring the delicate structure of the walls of the cell, each edge is furnished with a strengthening rim of wax. The bulk of these stores is never broken, except in bad wet seasons, in times of great dearth, or upon any suspension of torpidity during their hibernation. For the ordinary and daily consumption of those of the community whose labours confine them to the hive, open stores are left. As of course it occupies the excursions of several bees for some time to fill one of these vases, and to prevent the liquid flowing out, as it might do from its exceeding tenuity through the influence of the summer heat, and the then increased temperature of the hive, as well as from its inclined horizontal position,—this is guarded against by the precautional sagacity of the little creatures placing upon it from the deposit of the very first supply a sort of operculum, as before described, of a thicker consistency, which lies upon the top of its progressive increase, and thus prevents its oozing. It lies upon the honey across the transverse diameter of the cell, and consequently in a vertical position. Its purpose, like that of the flat pieces of wood which are placed upon the water of full pails when carried by the yoke, is to prevent its spilling or overflowing. This small cover has to be partially removed upon the arrival of a bee with fresh store, which she herself does by tearing aside a portion of it to enable her to regurgitate into the cavity the portion she has brought home; upon freeing herself from this she does not wait to restore the dilapidation she has caused, but proceeds on a fresh harvesting. Another bee, whose duty it is, then readapts this cover to its purpose, and repairs it. Their excursions to collect arevariously estimated at from one to three miles, and they make about ten a day. The bees, in their temporary distribution of labour, are something like the Indians which have caste, among whom each service has its special servitor, who never undertakes or interferes with the duties of another. The collection of pollen is almost as needful to the well-being of a hive as honey, this being used exclusively as the basis of the sustenance of the new brood in their larva state, in all their conditions of worker, drone, and queen, the perfect bee itself never partaking of it. It is variously commingled upon its application to use with secretions of their own, which convert it into bee bread or royal jelly, as the case may be, to fit it for its special employment, which is done by the nurse-bees, who diligently attend to the nurture of all the young. The cells for storing this material are not so numerous as the honey-cells, and they are jotted about without any distinct order, amongst them. When a bee arrives with her store of pollen on the edge of one of these cells, she turns round with her back to it and thrusts it in as fast as she can free it from her legs, both by their aid and the twisting about of her abdomen, and then, like the honey-gatherer, commences another journey. As soon as she is gone, another bee manipulates it with a small stock of honey, and packs it closely in. Whilst all this is doing, the set which watch the condition of the hive, like surveyors, to apply repairs where necessary, or to add strength and further support to the suspended cakes of comb, impatiently await the return of the collectors of propolis; this they tear from their shanks as fast as they arrive and as quickly as they can, for it rapidly hardens, especially in fine hot weather, and they convey it away for their requirements, whilstthose which collected it fly off for fresh supplies, should more be needed. Concurrently with the execution of all these things, wax is still being secreted by festoons of bees suspended wherever there is space, the sculpturer bees are still moulding cells, the queen is still laying eggs, deferentially attended, as usual, by her maids of honour; the young brood is still being fed; other bees are ventilating the hive at its entrance and within its streets and lanes by the rapid vibration of their wings; the sentinels are diligently keeping guard to repel the inimical intrusion of wasps or snails or woodlice, or the moth which is so destructive to the interior in her larva state, from the covered moveable silken retreat which she constructs impervious to the sting, and thence with impunity gets at the silk of the cocoons and consumes the wax, making, when once fairly domiciled, such fearful havoc in the hive that the bees are fain to desert it,—and the many other numerous enemies which lust for the luscious honey, or whose voracity is attracted by the poor little diligent bees themselves, but who in such contingencies exhibit invincible courage, which, if not always successful in its efforts, is always meritorious. Where self-preservation is not the prompter, or the rivalry of love the instigator, but the duration of which is limited to a season, the feuds of the animal world all seem to proceed from the urgency of their gastronomic suggestions, the acrimony of which urges craft and strength to their most powerful exhibition. To allay hunger, destruction is perpetrated and order despoiled, and thus our bees become the victims of the imperativeness of this universal law. But sometimes they are triumphant over a very large enemy; for instance, an intrusive mouse, or a slug that has slimed itsway through the arched portal. They have been known to kill these enemies within the hive as they could not make them withdraw, but perplexity results from their success; they are, however, gifted with the sagacity to know that the putridity of these masses will poison with its effluvia the atmosphere of their city which no ventilation can purify, and they convert that part of their metropolis into a mausoleum, covering the carcases with a coating of propolis, alone or mixed with wax, as before noticed. Those which execute this summary martial law are the sentinels—the armed police of the hive—which guard its entrance and avenues, and patrol its streets and lanes and passages. Concurrently with all these doings, scavengers are heedfully conveying away any particles of dirt or other undesirable superfluity which may have accidentally found its way in. That all these labours produce fatigue and exact rest is proved by the circumstance that many bees are always observed in a state of repose,—perhaps only forty winks during the day just to restore exhausted energy,—for they are soon seen again to resume their toil, this inactivity never being idleness. Whether they proceed with the same kind of employment upon the renewal of their work is not known, nor how long lasts a particular kind of labour, but the change of occupation may be one of frequent occurrence, and it may be presumed that each bee severally and successively undertakes each task, that the faculty for exercising it may not be extinguished. It is very possibly a daily change, which circulates through the entire civic population of workers.
