To allow the bees the power of making three kinds of bees from one kind of eggs, which would be virtually constituting a third sex, an anomaly not often found. The drones being males, and workers imperfect females with generative organs undeveloped, renders the anomaly of the third sex unnecessary. On the other side it might be said in reply: That if food and treatment would create or produce organs of generation in the female, by making an egg destined for a worker into a queen, (a fact which all apiarians admit,) why not food and treatment make the drone? Is the difficulty of developing _one_ kind of sexual organs greater than another? Respecting the anomaly of the eggs of some queens producing only drones, the question might be asked, Is this more of an anomaly than that of ordinary queens which are said to germinate eggs in distinct series? It is all out of the usual line. Other animals or insects usually produce the sexes promiscuously. As we are ignorant of causes deciding sex in any case, we must acknowledge mystery to belong to both sides of the question here. The stumbling-block of more than two sexes, which seems so necessary to make plain, is no greater here than with some species of ants, that have, as we are told, king, queen, soldier and laborer. Four distinct and differently formed bodies, all belonging to one nest, and descended from one mother. Whether there are four distinct kinds of eggs producing them, or the power is given to the workers to develop such as are wanted, from one kind, we cannot say. If we make two kinds of eggs, it helps the matter but very little. There is still an anomaly. There is but one perfect female in a nest to germinate eggs, and the myriads produced (being over 80,000 in twenty-four hours, according to some historians) shows that the fecundity of our queen-bee is not a parallel case by any means. And yet they are similar, by having their offspring provided for without an effort of their own. I shall leave this matter for the present, hoping that _something conclusive_ may occur in the course of my experiments, or those of others. At present I am inclined to think that the eggs are all alike, but am not fully satisfied. I am aware that this matter is of but little value or interest to many, but myself and a few others have "Yankee inquisitiveness" pretty well developed, and would like to _know_ how it _was_ managed. As for workers proving occasionally fertile, I have but little to say. After years of close observation directed to this point, I have been unable to discover anything to establish this opinion. Neither have I found the black bees described by some authors. It is true that in the middle or latter part of summer a portion will be much darker than others, and perhaps rather smaller, and some of them with their wings somewhat worn, probably the result of continued labor, peculiar food, or some incidental circumstance.
