In these cells eggs will have been placed by the old queen, or more probably perhaps by one of the workers, before the departure of the swarm; the eggs will have been taken from some cell that was near, and will be exactly the same as those from which the ordinary worker-bee is hatched. And yet the bee that will in due time come out is so unlike the others that she might almost belong to an entirely different race. Her life will last four or five years, instead of the six or seven weeks that are the portion of her worker-sister. Her body will be twice as long, her color clearer, and more golden; her sting will be curved, and her eyes have only seven or eight thousand facets instead of twelve or thirteen thousand. Her brain will be smaller, and she will have no brushes, no pockets in which to secrete the wax, no baskets to gather the pollen. She will not crave for air, or the light of the sun; she will die without once having sipped at a flower. She will spend her life in the darkness, in the midst of an ever-moving crowd; and her one thought, her one idea, will be the constant search for cradles in which she can lay her eggs. It is probable that she will not, twice in her life, look on the light of day; and as a rule she will only once make use of her wings. A week has passed, let us say, since the old queen has gone, at the head of the swarm. The royal princesses who still are asleep in their cots are not all of the same age; for the bees prefer that there should be an interval between the birth of each one. The time of the eldest princess draws near; she is already astir, and has begun eagerly to gnaw at the rounded lid of her cradle, whose walls the workers have already for several hours been thinning, so as to make it easier for her to get out. And at last she thrusts her head through the lid; the workers at once rush eagerly to her, and help her to get clear; they brush her, caress her and clean her, and soon she is able to take her first trembling steps on the comb. At first, her food will be the same as that given to the ordinary workers, but after a very few days she is nourished on the choicest and purest milk, which is known as "royal jelly." The princess, at the moment of birth, is weak and pale; but in a very few minutes she gets her strength, and then a strange restlessness comes over her; she seems to know that other princesses are near, that her kingdom has yet to be won, that close by rivals are hiding; and she eagerly paces the waxen walls in search of her enemies.
