If you desire a more definite proof, you have but to watch a bee that shall just have discovered a few drops of honey on your window-sill or the corner of your table. She will immediately gorge herself with it; and so eagerly, that you will have time, without fear of disturbing her, to mark her tiny belt with a touch of paint. But this gluttony of hers is all on the surface; the honey will not pass into the stomach proper, into what we might call her personal stomach, but remains in the sac, the first stomach,--that of the community, if one may so express it. This reservoir full, the bee will depart, but not with the free and thoughtless motion of the fly or butterfly; she, on the contrary, will for some moments fly backwards, hovering eagerly about the table or window, with her head turned toward the room.
She is reconnoitring, fixing in her memory the exact position of the treasure. Thereupon she will go to the hive, disgorge her plunder into one of the provision-cells, and in three or four minutes return, and resume operations at the providential window. And thus, while the honey lasts, will she come and go, at intervals of every five minutes, till evening, if need be; without interruption or rest; pursuing her regular journeys from the hive to the window, from the window back to the hive.
[46] Many of those who have written on bees have thought fit to adorn the truth; I myself have no such desire. For studies of this description to possess any interest, it is essential that they should remain absolutely sincere. Had the conclusion been forced upon me that bees are incapable of communicating to each other news of an event occurring outside the hive, I should, I imagine, as a set-off against the slight disappointment this discovery would have entailed, have derived some degree of satisfaction in recognising once more that man, after all, is the only truly intelligent being who inhabits our globe. And there comes too a period of life when we have more joy in saying the thing that is true than in saying the thing that merely is wonderful. Here as in every case the principle holds that, should the naked truth appear at the moment less interesting, less great and noble than the imaginary embellishment it lies in our power to bestow, the fault must rest with ourselves who still are unable to perceive the astonishing relation in which this truth always must stand to our being, and to universal law; and in that case it is not the truth, but our intellect, that needs embellishment and ennoblement.
I will frankly confess, therefore, that the marked bee often returns alone. Shall we believe that in bees there exists the same difference of character as in men; that of them too some are gossips, and others prone to silence? A friend who stood by and watched my experiment, declared that it was evidently mere selfishness or vanity that caused so many of the bees to refrain from revealing the source of their wealth, and from sharing with others the glory of an achievement that must seem miraculous to the hive. These were sad vices indeed, which give not forth the sweet odour, so fragrant and loyal, that springs from the home of the many thousand sisters. But, whatever the cause, it often will also happen that the bee whom fortune has favoured will return to the honey accompanied by two or three friends. I am aware that Sir John Lubbock, in the appendix to his book on "Ants, Bees, and Wasps," records the results of his investigations in long and minute tables; and from these we are led to infer that it is a matter of rarest occurrence for a single bee to follow the one who has made the discovery. The learned naturalist does not name the race of bees which he selected for his experiments, or tell us whether the conditions were especially unfavourable. As for myself I only can say that my own tables, compiled with great care,--and every possible precaution having been taken that the bees should not be directly attracted by the odour of the honey,--establish that on an average one bee will bring others four times out of ten.
I even one day came across an extraordinary little Italian bee, whose belt I had marked with a touch of blue paint. In her second trip she brought two of her sisters, whom I imprisoned, without interfering with her. She departed once more, and this time returned with three friends, whom I again confined, and so till the end of the afternoon, when, counting my prisoners, I found that she had told the news to no less than eighteen bees.
In fact you will find, if you make this experiment yourself, that communication, if not general, at least is frequent. The possession of this faculty is so well known to American bee-hunters that they trade upon it when engaged in searching for nests. Mr. Josiah Emery remarks on this head (quoted by Romanes in his "Intellect of Animals "): "Going to a field or wood at a distance from tame bees with their box of honey, they gather up from the flowers and imprison one or more bees, and after they have become sufficiently gorged, let them out to return to their home with their easily gotten load. Waiting patiently a longer or shorter time, according to the distance of the bee-tree, the hunter scarcely ever fails to see the bee or bees return accompanied by other bees, which are in like manner imprisoned till they in turn are filled; then one or more are let out at places distant from each other, and the direction in which the bee flies noted; and thus, by a kind of triangulation, the position of the bee-tree proximately ascertained."
[47]
You will notice too in your experiments that the friends who appear to obey the behests of good fortune do not always fly together, and that there will often be an interval of several seconds between the different arrivals. As regards these communications, therefore, we must ask ourselves the question that Sir John Lubbock has solved as far as the ants are concerned.
Do the comrades who flock to the treasure only follow the bee that first made the discovery, or have they been sent on by her, and do they find it through following her indications, her description of the place where it lies? Between these two hypotheses, that refer directly to the extent and working of the bee's intellect, there is obviously an enormous difference. The English savant has succeeded, by means of an elaborate and ingenious arrangement of gangways, corridors, moats full of water, and flying bridges, in establishing that the ants in such cases do no more than follow in the track of the pioneering insect. With ants, that can be made to pass where one will, such experiments are possible; but for the bee, whose wings throw every avenue open, some other expedient must of necessity be contrived. I imagined the following, which, though it gave no definite result, might yet, under more favourable conditions, and if organised more carefully, give rise to definite and satisfactory conclusions.
My study in the country is on the first floor, above a somewhat lofty room; sufficiently high, therefore, to be out of the ordinary range of the bees' flight, except at times when the chestnuts and lime trees are in bloom. And for more than a week before I started this experiment I had kept on my table an open comb of honey, without the perfume having attracted, or induced the visit of, a single bee. Then I went to a glass hive that was close to the house, took an Italian bee, brought her to my study, set her on the comb, and marked her while she was feeding.
When satisfied, she flew away and returned to the hive. I followed, saw her pass over the surface of the crowd, plunge her head into an empty cell, disgorge her honey, and prepare to set forth again. At the door of the hive I had placed a glass box, divided by a trap into two compartments. The bee flew into this box; and as she was alone, and no other bee seemed to accompany or follow her, I imprisoned her and left her there. I then repeated the experiment on twenty different bees in succession. When the marked bee reappeared alone, I imprisoned her as I had imprisoned the first. But eight of them came to the threshold of the hive and entered the box accompanied by two or three friends. By means of the trap I was able to separate the marked bee from her companions, and to keep her a prisoner in the first compartment. Then, having marked her companions with a different colour, I threw open the second compartment and set them at liberty, myself returning quickly to my study to await their arrival. Now it is evident that if a verbal or magnetic communication had passed, indicating the place, describing the way, etc., a certain number of the bees, having been furnished with this information, should have found their way to my room. I am compelled to admit that there came but a single one. Was this mere chance, or had she followed instructions received? The experiment was insufficient, but circumstances prevented me from carrying it further. I released the "baited" bees, and my study soon was besieged by the buzzing crowd to whom they had taught the way to the treasure.
We need not concern ourselves with this incomplete attempt of mine, for many other curious traits compel us to recognise the existence among the bees of spiritual communications that go beyond a mere "yes" or "no," and that are manifest in cases where mere example or gesture would not be sufficient. Of such, for instance, are the remarkable harmony of their work in the hive, the extraordinary division of labour, the regularity with which one worker will take the place of another, etc. I have often marked bees that went foraging in the morning, and found that, in the afternoon, unless flowers were specially abundant, they would be engaged in heating and fanning the brood-cells, or perhaps would form part of the mysterious, motionless curtain in whose midst the wax-makers and sculptors would be at work. Similarly I have noticed that workers whom I have seen gathering pollen for the whole of one day, will bring no pollen back on the morrow, but will concern themselves exclusively with the search for nectar, and viceversa.
[48]
And further, we might mention what M. Georges de Layens, the celebrated French apiarist, terms the "Distribution of Bees over Melliferous Plants." Day after day, at the first hour of sunrise, the explorers of the dawn return, and the hive awakes to receive the good news of the earth. "The lime trees are blossoming to-day on the banks of the canal." "The grass by the roadside is gay with white clover." "The sage and the lotus are about to open." "The mignonette, the lilies are overflowing with pollen." Whereupon the bees must organise quickly, and arrange to divide the work. Five thousand of the sturdiest will sully forth to the lime trees, while three thousand juniors go and refresh the white clover. Those who yesterday were absorbing nectar from the corollas will to-day repose their tongue and the glands of their sac, and gather red pollen from the mignonette, or yellow pollen from the tall lilies; for never shall you see a bee collecting or mixing pollen of a different colour or species; and indeed one of the chief pre-occupations of the hive is the methodical bestowal of these pollens in the store-rooms, in strict accordance with their origin and colour. Thus does the hidden genius issue its commands. The workers immediately sally forth, in long black files, whereof each one will fly straight to its allotted task. "The bees," says De Layens, "would seem to be perfectly informed as to the locality, the relative melliferous value, and the distance of every melliferous plant within a certain radius from the hive. "If we carefully note the different directions in which these foragers fly, and observe in detail the harvest they gather from the various plants around, we shall find that the workers distribute themselves over the flowers in proportion not only to the numbers of flowers of one species, but also to their melliferous value. Nay, more--they make daily calculations as to the means of obtaining the greatest possible wealth of saccharine liquid. In the spring, for instance, after the willows have bloomed, when the fields still are bare, and the first flowers of the woods are the one resource of the bees, we shall see them eagerly visiting gorse and violets, lungworts and anemones. But, a few days later, when fields of cabbage and colza begin to flower in sufficient abundance, we shall find that the bees will almost entirely forsake the plants in the woods, though these be still in full blossom, and will confine their visits to the flowers of cabbage and colza alone. In this fashion they regulate, day by day, their distribution over the plants, so as to collect the greatest value of saccharine liquid in the least possible time.
"It may fairly be claimed, therefore, for the colony of bees that, in its harvesting labours no less than in its internal economy, it is able to establish a rational distribution of the number of workers without ever disturbing the principle of the division of labour."
[49]
But what have we to do, some will ask, with the intelligence of the bees? What concern is it of ours whether this be a little less or a little more? Why weigh, with such infinite care, a minute fragment of almost invisible matter, as though it were a fluid whereon depended the destiny of man? I hold, and exaggerate nothing, that our interest herein is of the most considerable. The discovery of a sign of true intellect outside ourselves procures us something of the emotion Robinson Crusoe felt when he saw the imprint of a human foot on the sandy beach of his island. We seem less solitary than we had believed. And indeed, in our endeavour to understand the intellect of the bees, we are studying in them that which is most precious in our own substance: an atom of the extraordinary matter which possesses, wherever it attach itself, the magnificent power of transfiguring blind necessity, of organising, embellishing, and multiplying life; and, most striking of all, of holding in suspense the obstinate force of death, and the mighty, irresponsible wave that wraps almost all that exists in an eternal unconsciousness.
Were we sole possessors of the particle of matter that, when maintained in a special condition of flower or incandescence, we term the intellect, we should to some extent be entitled to look on ourselves as privileged beings, and to imagine that in us nature achieved some kind of aim; but here we discover, in the hymenoptera, an entire category of beings in whom a more or less identical aim is achieved. And this fact, though it decide nothing perhaps, still holds an honourable place in the mass of tiny facts that help to throw light on our position in this world. It affords even, if considered from a certain point of view, a fresh proof of the most enigmatic part of our being; for the superpositions of destinies that we find in the hive are surveyed by us from an eminence loftier than any we can attain for the contemplation of the destinies of man. There we see before us, in miniature, the large and simple lines that in our own disproportionate sphere we never have the occasion to disentangle and follow to the end. Spirit and matter are there, the race and the individual, evolution and permanence, life and death, the past and the future; all gathered together in a retreat that our hand can lift and one look of our eye embrace. And may we not reasonably ask ourselves whether the mere size of a body, and the room that it fills in time and space, can modify to the extent we imagine the secret idea of nature; the idea that we try to discover in the little history of the hive, which in a few days already is ancient, no less than in the great history of man, of whom three generations overlap a long century?
