And, last of all, it is the spirit of the hive which decides on the hour at which the bees shall swarm; the hour, that is, when we find a whole people, who have reached the very height of prosperity and power, suddenly abandoning, in favor of the generation that is to follow, all their wealth and their palaces, their homes and the fruits of their labor, content themselves to face the perils and hardships of a journey into a new and distant country. This act will always bring poverty with it and sometimes ruin; and the people who once were so happy are scattered abroad in obedience to a law that they recognize to be greater than their own happiness. These things that happen to the bee are regarded by us in the way we regard most things that happen in the world. We note some of the bees' habits; we say, they do this, and do that, they work in such and such a way, this is how their queens are born; we observe that the workers are all females and that they swarm at a certain time. And having said this, we think that we know them, and ask nothing more. We watch them hastening from flower to flower, we see the constant movement within the hive; and we tell ourselves that we understand all about their life. But the moment that we try to come nearer the truth, to see more clearly, we find puzzling questions confronting us, questions as to what part is played by destiny and what part by will, how much is due to intelligence and how much to nature; difficult questions, these, that are never absent even from the most simple acts of our own daily life. Our hive, then, is preparing to swarm, making ready for the great sacrifice to the generation that is to come. In obedience to the order given by the "spirit of the hive," sixty or seventy thousand bees out of the eighty or ninety thousand that form the whole population, will forsake their old city at a given hour. They will not be leaving it at a moment of great unhappiness; they have not suddenly made up their minds to abandon a home that has been rendered miserable by hunger or illness, or ruined by war. No; on the contrary, preparations have for a long time been made, and the hour most favorable for departure patiently awaited. If the hive were poor, or had suffered from storm or robbery; or if some misfortune had befallen the royal family, the bees would not dream of going away. They do this only when everything is at its very best in the hive; at a time when, thanks to the enormous amount of work done in the spring, the immense palace of wax has its 120,000 well-arranged cells overflowing with honey and with the many-colored flour, known as "bees' bread," on which the larvæ are fed.
