"However, within the hollows of the earth, When from one quarter the wind builds up, lunges,muscles the deep caves with its headstrong power, The earth leans hard where the force of wind has pressed it; Then above ground, the higher the house is built, The nearer it rises to the sky, the worse Will it lean that way and jut out perilously, The beams wrenched loose and hanging ready to fall. And to think, men can't believe that for this world Some time of death and ruin lies in wait, Yet they see so great a mass of earth collapse! And the winds pause for breath—that's lucky, for else No force could rein things galloping to destruction. But since they pause for breath, to rally their force, Come building up and then fall driven back, More often the earth will threaten ruin than Perform it. The earth will lean and then sway back, Its wavering mass restored to the right poise That explains why all houses reel, top floor Most then the middle, and ground floor hardly at all."
