And at last she goes, and wanders from comb to comb, her unsatisfied wrath finding vent in a war-song, or angry complaint, that every bee-keeper knows; resembling somewhat the note of a distant trumpet of silver; so intense, in its passionate feebleness, as to be clearly audible, in the evening especially, two or three yards from the double walls of the most carefully enclosed hive.
Upon the workers this royal cry has a magical effect. It terrifies them, it induces a kind of respectful stupor; and when the queen sends it forth, as she halts in front of the cells whose approach is denied her, the guardians who have but this moment been hustling her, pushing her back, will at once desist, and wait, with bent head, till the cry shall have ceased to resound. Indeed, some believe that it is thanks to the prestige of this cry, which the Sphinx Atropos imitates, that the latter is able to enter the hive, and gorge itself with honey, without the least molestation on the part of the bees.
For two or three days, sometimes even for five, this indignant lament will be heard, this challenge that the queen addresses to her well protected rivals. And as these in their turn develop, in their turn grow anxious to see the light, they too set to work to gnaw the lids of their cells. A mighty disorder would now appear to threaten the republic. But the genius of the hive, at the time that it formed its decision, was able to foretell every consequence that might ensue; and the guardians have had their instructions: they know exactly what must be done, hour by hour, to meet the attacks of a foiled instinct, and conduct two opposite forces to a successful issue. They are fully aware that if the young queens should escape who now clamour for birth, they would fall into the hands of their elder sister, by this time irresistible, who would destroy them one by one. The workers, therefore, will pile on fresh layers of wax in proportion as the prisoner reduces, from within, the walls of her tower; and the impatient princess will ardently persist in her labour, little suspecting that she has to deal with an enchanted obstacle, that rises ever afresh from its ruin. She hears the war-cry of her rival; and already aware of her royal duty and destiny, although she has not yet looked upon life, nor knows what a hive may be, she answers the challenge from within the depths of her prison. But her cry is different; it is stifled and hollow, for it has to traverse the walls of a tomb; and, when night is falling, and noises are hushed, and high over all there reigns the silence of the stars, the apiarist who nears these marvellous cities and stands, questioning, at their entrance, recognises and understands the dialogue that is passing between the wandering queen and the virgins in prison. To the young princesses, however, this prolonged reclusion is of material benefit; for when they at last are freed they have grown mature and vigorous, and are able to fly. But during this period of waiting the strength of the first queen has also increased, and is sufficient now to enable her to face the perils of the voyage. The time has arrived, therefore, for the departure of the second swarm, or "cast," with the first-born of the queens at its head. No sooner has she gone than the workers left in the hive will set one of the prisoners free; and she will evince the same murderous desires, send forth the same cries of anger, until, at last, after three or four days, she will leave the hive in her turn, at the head of the tertiary swarm; and so in succession, in the case of "swarming fever," till the mother-city shall be completely exhausted.
Swammerdam cites a hive that, through its swarms and the swarms of its swarms, was able in a single season to found no less than thirty colonies.
Such extraordinary multiplication is above all noticeable after disastrous winters; and one might almost believe that the bees, forever in touch with the secret desires of nature, are conscious of the dangers that menace their race. But at ordinary times this fever will rarely occur in a strong and well-governed hive. There are many that swarm only once; and some, indeed, not at all.
After the second swarm the bees, as a rule, will renounce further division, owing either to their having observed the excessive feebleness of their own stock, or to the prudence urged upon them by threatening skies. In that case they will allow the third queen to slaughter the captives; ordinary life will at once be resumed, and pursued with the more ardour for the reason that the workers are all very young, that the hive is depopulated and impoverished, and that there are great voids to fill before the arrival of winter.
[73]
The departure of the second and third swarms resembles that of the first, and the conditions are identical, with the exception that the bees are fewer in number, less circumspect, and lacking in scouts; and also that the young and virgin queen, being unencumbered and ardent, will fly much further, and in the first stage lead the swarm to a considerable distance from the hive. The conduct of these second and third migrations will be far more rash, and their future more problematical. The queen at their head, the representative of the future, has not yet been impregnated. Their entire destiny depends on the ensuing nuptial flight. A passing bird, a few drops of rain, a mistake, a cold wind-any one of these may give rise to irremediable disaster. Of this the bees are so well aware that when the young queen sallies forth in quest of her lover, they often will abandon the labours they have begun, will forsake the home of a day that already is dear to them, and accompany her in a body, dreading to let her pass out of their sight, eager, as they form closely around her, and shelter her beneath their myriad devoted wings, to lose themselves with her, should love cause her to stray so far from the hive that the as yet unfamiliar road of return shall grow blurred and hesitating in every memory. But so potent is the law of the future that none of these uncertainties, these perils of death, will cause a single bee to waver. The enthusiasm displayed by the second and third swarms is not less than that of the first. No sooner has the mother-city pronounced its decision than a battalion of workers will flock around each dangerous young queen, eager to follow her fortunes, to accompany her on the voyage where there is so much to lose, and so little to gain beyond the desire of a satisfied instinct. Whence do they derive the energy we ourselves never possess, whereby they break with the past as though with an enemy? Who is it selects from the crowd those who shall go forth, and declares who shall remain? No special class divides those who stay from those who wander abroad; it will be the younger here and the elder there; around each queen who shall never return veteran foragers jostle tiny workers, who for the first time shall face the dizziness of the blue. Nor is the proportionate strength of a swarm controlled by chance or accident, by the momentary dejection or transport of an instinct, thought, or feeling. I have more than once tried to establish a relation between the number of bees composing a swarm and the number of those that remain; and although the difficulties of this calculation are such as to preclude anything approaching mathematical precision, I have at least been able to gather that this relation--if we take into account the brood-cells, or in other words the forthcoming births--is sufficiently constant to point to an actual and mysterious reckoning on the part of the genius of the hive.
[75]
We will not follow these swarms on their numerous, and often most complicated, adventures. Two swarms, at times, will join forces; at others, two or three of the imprisoned queens will profit by the confusion attending the moment of departure to elude the watchfulness of their guardians and join the groups that are forming. Occasionally, too, one of the young queens, finding herself surrounded by males, will cause herself to be impregnated in the swarming flight, and will then drag all her people to an extraordinary height and distance. In the practice of apiculture these secondary and tertiary swarms are always returned to the mother-hive. The queens will meet on the comb; the workers will gather around and watch their combat; and, when the stronger has overcome the weaker they will then, in their ardour for work and hatred of disorder, expel the corpses, close the door on the violence of the future, forget the past, return to their cells, and resume their peaceful path to the flowers that await them.
[ 76 ]
We will now, in order to simplify matters, return to the queen whom the bees have permitted to slaughter her sisters, and resume the account of her adventures. As I have already stated, this massacre will be often prevented, and often sanctioned, at times even when the bees apparently do not intend to issue a second swarm; for we notice the same diversity of political spirit in the different hives of an apiary as in the different human nations of a continent. But it is clear that the bees will act imprudently in giving their consent; for if the queen should die, or stray in the nuptial flight, it will be impossible to fill her place, the workers' larvae having passed the age when they are susceptible of royal transformation. Let us assume, however, that the imprudence has been committed; and behold our first-born, therefore, unique sovereign, and recognised as such in the spirit of her people. But she is still a virgin. To become as was the mother before her, it is essential that she should meet the male within the first twenty days of her life. Should the event for some reason be delayed beyond this period, her virginity becomes irrevocable. And yet we have seen that she is not sterile, virgin though she be. There confronts us here the great mystery--or precaution--of Nature, that is known as parthenogenesis, and is common to a certain number of insects, such as the aphides, the lepidoptera of the Psyche genus, the hymenoptera of the Cynipede family, etc. The virgin queen is able to lay; but from all the eggs that she will deposit in the cells, be these large or small, there will issue males alone; and as these never work, as they live at the expense of the females, as they never go foraging except on their own account, and are generally incapable of providing for their subsistence, the result will be, at the end of some weeks, that the last exhausted worker will perish, and the colony be ruined and totally annihilated. The queen, we have said, will produce thousands of drones; and each of these will possess millions of the spermatozoa whereof it is impossible that a single one can have penetrated into the organism of the mother. That may not be more astounding, perhaps, than a thousand other and analogous phenomena; and, indeed, when we consider these problems, and more especially those of generation, the marvellous and the unexpected confront us so constantly--occurring far more frequently, and above all in far less human fashion, than in the most miraculous fairy stories--that after a time astonishment becomes so habitual with us that we almost cease to wonder.
The fact, however, is sufficiently curious to be worthy of notice. But, on the other hand, how shall we explain to ourselves the aim that nature can have in thus favouring the valueless drones at the cost of the workers who are so essential? Is she afraid lest the females might perhaps be induced by their intellect unduly to limit the number of their parasites, which, destructive though they be, are still necessary for the preservation of the race? Or is it merely an exaggerated reaction against the misfortune of the unfruitful queen? Can we have here one of those blind and extreme precautions which, ignoring the cause of the evil, overstep the remedy; and, in the endeavour to prevent an unfortunate accident, bring about a catastrophe? In reality--though we must not forget that the natural, primitive reality is different: from that of the present, for in the original forest the colonies might well be far more scattered than they are to-day--in reality the queen's unfruitfulness will rarely be due to the want of males, for these are very numerous always, and will flock from afar; but rather to the rain, or the cold, that will have kept her too long in the hive, and more frequently still to the imperfect state of her wings, whereby she will be prevented from describing the high flight in the air that the organ of the male demands. Nature, however, heedless of these more intrinsic causes, is so deeply concerned with the multiplication of males, that we sometimes find, in motherless hives, two or three workers possessed of so great a desire to preserve the race that, their atrophied ovaries notwithstanding, they will still endeavour to lay; and, their organs expanding somewhat beneath the empire of this exasperated sentiment, they will succeed in depositing a few eggs in the cells; but from these eggs, as from those of the virgin mother, there will, issue only males. Here we behold the active intervention of a superior though perhaps imprudent will, which offers irresistible obstruction to the intelligent will of a life. In the insect world such interventions are comparatively frequent, and much can be gained from their study; for this world being more densely peopled and more complex than others, certain special desires of nature are often more palpably revealed to us there; and she may even at times be detected in the midst of experiments we might almost be warranted in regarding as incomplete. She has one great and general desire, for instance, that she displays on all sides; the amelioration of each species through the triumph of the stronger. This struggle, as a rule, is most carefully organised. The hecatomb of the weak is enormous, but that matters little so long as the victors' reward be effectual and certain. But there are cases when one might almost imagine that nature had not had time enough to disentangle her combinations; cases where reward is impossible, and the fate of the victor no less disastrous than that of the vanquished. And of such, selecting an instance that will not take us too far from our bees, I know of no instance more striking than that of the triongulins of the _Sitaris colletes._ And it will be seen that, in many details, this story is less foreign to the history of man than might perhaps be imagined.
These triongulins are the primary larvae of a parasite proper to a wild, obtuse-tongued, solitary bee, the Colletes, which builds its nest in subterranean galleries. It is their habit to lie in wait for the bee at the approach to these galleries; and then, to the number of three, four, five, or often of more, they will leap on her back, and bury themselves in her hair. Were the struggle of the weak against the strong to take place at this moment there would be no more to be said, and all would pass in accordance with universal law. But, for a reason we know not, their instinct requires, and nature has consequently ordained, that they should hold themselves tranquil so long as they remain on the back of the bee. They patiently bide their time while she visits the flowers, and constructs and provisions her cells. But no sooner has an egg been laid than they all spring upon it; and the innocent colletes carefully seals down her cell, which she has duly supplied with food, never suspecting that she has at the same time ensured the death of her offspring.
