To follow the various phases of the secretion and employment of wax by a swarm that is beginning to build, is a matter of very great difficulty. All comes to pass in the blackest depths of the crowd, whose agglomeration, growing denser and denser, produces the temperature needful for this exudation, which is the privilege of the youngest bees. Huber, who was the first to study these phenomena, bringing incredible patience to bear and exposing himself at times to very serious danger, devotes to them more than two hundred and fifty pages; which, though of considerable interest, are necessarily somewhat confused. But I am not treating this subject technically; and while referring when necessary to Huber's admirable studies, I shall confine myself generally to relating what is patent to any one who may gather a swarm into a glass hive. We have to admit, first of all, that we know not yet by what process of alchemy the honey transforms itself into wax in the enigmatic bodies of our suspended bees. We can only say that they will remain thus suspended for a period extending from eighteen to twenty-four hours, in a temperature so high that one might almost believe that a fire was burning in the hollow of the hive; and then white and transparent scales will appear at the opening of four little pockets that every bee has underneath its abdomen. When the bodies of most of those who form the inverted cone have thus been adorned with ivory tablets, we shall see one of the bees, as though suddenly inspired, abruptly detach herself from the mass, and climb over the backs of the passive crowd till she reach the inner pinnacle of the cupola. To this she will fix herself solidly, dislodging, with repeated blows of her head, such of her neighbours as may seem to hamper her movements. Then, with her mouth and claws, she will seize one of the eight scales that hang from her abdomen, and at once proceed to clip it and plane it, extend it, knead it with her saliva, bend it and flatten it, roll it and straighten it, with the skill of a carpenter handling a pliable panel. When at last the substance, thus treated, appears to her to possess the required dimensions and consistency, she will attach it to the highest point of the dome, thus laying the first, or rather the keystone of the new town; for we have here an inverted city, hanging down from the sky, and not rising from the bosom of earth like a city of men.
