Every ant-hill is in a strange hurry & confusion; & all the winged ants, agitated by some violent impulse, are leaving their homes; &, bent on emigration, swarm by myriads in the air, to the great emoulment of the hirundines, which fare luxuriously. Those that escape the swallows return no more to their nests, but looking out for new retreats, lay a foundation for future colonies. All the females at these times are pregnant.
