When the moon shall have faded out from the sky, and the sun shall shine at noonday a dull cherry red, and the seas shall be frozen over, and the icecap shall have crept downward to the equator from either pole… when all the cities shall have long been dead and crumbled into dust, and all life shall be on the last verge of extinction on this globe; then, on a bit of lichen, growing on the bald rocks beside the eternal snows of Panama, shall be seated a tiny insect, preening its antennae in the glow of the worn-out sun, the sole survivor of animal life on this our earth – a melancholy bug.
