Part 2 (1/2)
It has been noticed that the queen bee commences laying in the latter part of winter, or early in spring, and long before there are any drones or males in the hive. (See remarks on Drones.) In what way are these eggs impregnated? Huber, by a long course of the most indefatigable observations, threw much light upon this subject. Before stating his discoveries, I must pay my humble tribute of grat.i.tude and admiration, to this wonderful man. It is mortifying to every scientific naturalist, and I might add, to every honest man acquainted with the facts, to hear such a man as Huber abused by the veriest quacks and imposters; while others who have appropriated from his labors, nearly all that is of any value in their works, to use the words of Pope,
”d.a.m.n with faint praise, a.s.sent with civil leer, And without sneering, teach the rest to sneer.”
Huber, in early manhood, lost the use of his eyes. His opponents imagine that in stating this fact, they have thrown merited discredit on all his pretended discoveries. But to make their case still stronger, they delight to a.s.sert that he saw every thing through the medium of his servant Francis Burnens, an ignorant peasant. Now this ignorant peasant was a man of strong native intellect, possessing that indefatigable energy and enthusiasm which are so indispensable to make a good observer. He was a n.o.ble specimen of a self-made man, and afterwards rose to be the chief magistrate in the village where he resided. Huber has paid the most admirable tribute to his intelligence, fidelity and indomitable patience, energy and skill.
It would be difficult to find, in any language, a better specimen of the true Baconian or _inductive_ system of reasoning, than Huber's work upon bees, and it might be studied as a model of the only true way of investigating nature, so as to arrive at reliable results.
Huber was a.s.sisted in his investigations, not only by Burnens, but by his own wife, to whom he was engaged before the loss of his sight, and who n.o.bly persisted in marrying him, notwithstanding his misfortune, and the strenuous dissuasions of her friends. They lived for more than the ordinary term of human life, in the enjoyment of uninterrupted domestic happiness, and the amiable naturalist scarcely felt, in her a.s.siduous attentions, the loss of his sight.
Milton is believed by many, to have been a better poet, for his blindness; and it is highly probable that Huber was a better Apiarian, for the same cause. His active and yet reflective mind demanded constant employment; and he found in the study of the habits of the honey bee, full scope for all his powers. All the facts observed, and experiments tried by his faithful a.s.sistants, were daily reported to him, and many inquiries were stated and suggestions made by him, which would probably have escaped his notice, if he had possessed the use of his eyes.
Few have such a command of both time and money as to enable them to carry on, for a series of years, on a grand scale, the most costly experiments. Apiarians owe more to Huber than to any other person. I have repeatedly verified the most important of his observations, and I take _the greatest delight_ in acknowledging my obligations to him, and in holding him up to my countrymen, as the PRINCE OF APIARIANS.
My Readers will pardon this digression. It would have been morally impossible for me to write a work on bees, without saying at least as much as this, in vindication of Huber.
I return to his discoveries on the impregnation of the Queen Bee. By a long course of experiments most carefully conducted, he ascertained that like many other insects, she is fecundated in the open air, and on the wing, and that the influence of this lasts for several years, and probably for life. He could not form any satisfactory conjecture, as to the way in which the eggs which were not yet developed in her ovaries, could be fertilized. Years ago, the celebrated Dr. John Hunter, and others, supposed that there must be a permanent receptacle for the male sperm, opening into the pa.s.sage for the eggs called the oviduct.
Dzierzon, who must be regarded as one of the ablest contributors of modern times, to Apiarian science, maintains this opinion, and states that he has found such a receptacle filled with a fluid, resembling the s.e.m.e.n of the drones. He nowhere, to my knowledge, states that he ever made microscopic examinations, so as to put the matter on the footing of demonstration.
In January and February of 1852, I submitted several Queen Bees to Dr.
Joseph Leidy of Philadelphia, for a scientific examination. I need hardly say to any Naturalist in this country, that Dr. Leidy has obtained the very highest reputation, both at home and abroad, as a skillful naturalist and microscopic anatomist. No man in this country or Europe, was more competent to make the investigations that I desired. He found in making his dissections, a small globular sac, not larger than a grain of mustard seed, (about 1/33 of an inch in diameter,) communicating with the oviduct, and filled with a whitish fluid, which when examined under the microscope, was found to abound in spermatozoa, or the animalculae, which are the unmistakable characteristics of the seminal fluid. Later in the season, the same substance was compared with some taken from the drones, and found to be exactly similar to it.
These examinations have settled, on the impregnable basis of demonstration, the mode in which the eggs of the Queen are vivified. In descending the oviduct to be deposited in the cells, they pa.s.s by the mouth of this seminal sac or spermatheca, and receive a portion of its fertilizing contents. Small as it is, its contents are sufficient to impregnate hundreds of thousands of eggs. In precisely the same way, the mother wasps and hornets are fecundated. The females alone of these insects survive the winter, and they begin, single-handed, the construction of a nest, in which, at first, only a few eggs are deposited. How could these eggs hatch, if the females which laid them, had not been impregnated, the previous season? Dissection proves them to have a spermatheca, similar to that of the Queen Bee.
Of all who have written against Huber, no one has treated him with more unfairness, misrepresentation, and I might almost add, malignity, than Huish. He maintains that the eggs of the Queen are impregnated by the drones, after she has deposited them in the cells, and accounts for the fact that brood is produced in the Spring, long before the existence of any drones in the hive, by a.s.serting that these eggs were deposited and impregnated late in the previous season, and have remained dormant, all winter, in the hive: and yet the same writer, while ridiculing the discoveries of Huber, advises that all the mother wasps should be killed in the Spring, to prevent them from founding families to commit depredations upon the bees! It never seems to have occurred to him, that the existence of a permanently impregnated mother wasp, was just as difficult to be accounted for, as the existence of a similarly impregnated Queen Bee.
EFFECT OF r.e.t.a.r.dED IMPREGNATION ON THE QUEEN BEE.
I shall now mention a fact in the physiology of the Queen Bee, more singular than any which has yet been related.
Huber, while experimenting to ascertain how the Queen was fecundated, confined some of his young Queens to their hives, by contracting the entrances, so that they were not able to go in search of the drones, until three weeks after their birth. To his amazement, these Queens whose impregnation was thus unnaturally r.e.t.a.r.ded, _never laid any eggs but such as produced drones_!!
He tried the experiment again and again, but always with the same result. Some Bee-Keepers, long before his time, had observed that all the brood in a hive were occasionally drones, and of course, that such colonies rapidly went to ruin. Before attempting any explanation of this astonis.h.i.+ng fact, I must call the attention of the reader, to another of the mysteries of the Bee-Hive,
FERTILE WORKERS.
It has already been remarked, that the workers are proved by dissection to be females, all of which, under ordinary circ.u.mstances, are barren.
Occasionally, some of them appear to be more fully developed than common, so as to be capable of laying eggs: these eggs, like those of Queens whose impregnation has been r.e.t.a.r.ded, _always produce drones_!
Sometimes, when a colony has lost its Queen, these drone-laying workers are exalted to her place, and treated with equal respect and affection, by the bees. Huber ascertained that these fertile workers were generally reared in the neighborhood of the young Queens, and he thought that they received some particles of the peculiar food or jelly on which the Queens are reared. (See Royal Jelly.) He did not pretend to account for the effect of r.e.t.a.r.ded impregnation; and made no experiments to determine the facts, as to the fecundation of these fertile workers.
Since the publication of Huber's work, nearly 50 years ago, no light has been shed upon the mysteries of drone-laying Queens and workers, until quite recently. Dzierzon appears to have been the first to ascertain the truth on this subject; and his discovery must certainly be ranked as unfolding one of the most astonis.h.i.+ng facts in all the range of animated nature. This fact seems, at first view, so absolutely incredible, that I should not dare to mention it, if it were not supported by the most indubitable evidence, and if I had not, (as I have already observed,) determined to state all important and well ascertained facts, without seeking, by any concealments, to pander to the prejudices of conceited, and often, very ignorant Bee-Keepers.
Dzierzon advances the opinion that impregnation is not needed in order that the eggs of the Queen may produce drones; but, that all impregnated eggs produce females, either workers or Queens; and all unimpregnated ones, males or drones! He states that he found drone-laying Queens in several of his hives, whose wings were so imperfect that they could not fly, and that on examination, they proved to be unfecundated. Hence he concluded that the eggs of the Queen Bee or fertile worker, had from the previous impregnation of the egg which produced them, sufficient vitality to produce the drone, which is a less highly organized insect, and one inferior to the Queen or workers. It had long been known, that the Queen deposits drone eggs in the large or drone cells, and worker eggs in the small or worker cells, and that she makes no mistakes.
Dzierzon inferred, therefore, that there was some way in which she was able to decide as to the s.e.x of the egg before it was laid, and that she must have a control over the mouth of the seminal sac, so as to be able to extrude her eggs, allowing them to receive or not, just as she pleased, a portion of its fertilizing contents. In this way he thought she determined the s.e.x, according to the size of the cells in which she laid them. Mr. Samuel Wagner of York, Pa., has recently communicated to me a very original and exceedingly ingenious theory of his own, which he thinks will account for all the facts without admitting that the Queen Bee has any special knowledge or will on the subject. He supposes that when she deposits her eggs in the worker cells, her body is slightly compressed by the size of the cells, and that the eggs, as they pa.s.s the spermatheca, receive in this manner, its vivifying influence. On the contrary, when she is egg-laying in drone cells, this compression cannot take place, the mouth of the spermatheca is kept closed, and the eggs are, necessarily, unfecundated. This theory may prove to be true, but at present, it is enc.u.mbered with some difficulties and requires further investigation, before it can be considered as fully established.
Leaving then the question whether the Queen exercises any volition in this matter, for the present undecided, I shall state some facts which occurred in the summer of 1852, in my own Apiary, and shall then endeavor to relieve, as far as possible, this intricate subject from some of the difficulties which embarra.s.s it.
In the Autumn of 1852, my a.s.sistant found, in one of my hives, a young Queen, the whole of whose progeny was drones. The colony had been formed by removing part of the combs containing bees, brood and eggs from another hive. It had only a few combs, and but a small number of bees.
They raised a new Queen in the manner which will hereafter be particularly described. This Queen had laid a number of eggs in one of the combs, and the young bees from some of them were already emerging from the cells. I perceived, at the first glance, that they were drones.
