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 passage 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 semen 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 animalculæ, 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 pass 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 asserting 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 Retarded 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 retarded, 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 astonishing fact, I must call the attention of the reader, to another of the mysteries of the Bee-Hive,
