And now to return to our swarming hive, where the bees have already given the signal for flight. And at once, as though with one sudden impulse, every gate in the city is flung open wide; and the black throng issues, or rather pours forth, in a double or treble jet, in a throbbing, quivering stream, that quickly divides and melts into space, where the thousands of beating wings weave a tissue humming with sound. And this for some moments will hover above the hive, rustling like gossamer silk; then, like a veil of gladness, all stirring and quivering, it floats to and fro, from the flowers up to the sky. The radiant mantle will gather together its four sunlit corners; and, like the fairy carpet, will fly across space, steering its straight, direct course to the willow, the pear-tree or lime on which the queen will have settled. Around her each wave comes to rest, as though on a golden nail, and from it there hangs the tissue of pearls and of golden wings. And then there is silence once more; and, in an instant, this mighty tumult, this bewildering golden hail that streamed upon every object near, becomes nothing more than a cluster of inoffensive and harmless bees, that wait patiently, in thousands of little motionless groups hanging down from the branch of a tree, for the scouts to return who have gone in search of a place of shelter. This is the first stage of what is known as the "primary swarm," at whose head the old queen is always to be found. The bees will usually settle on the shrub or the tree that is nearest the hive; for the queen, who has spent all her life in the dark and has almost forgotten the use of her wings, is afraid to venture too far.
