In modern life and experience there has been no near
 parallel to the catastrophe, of Tuesday, January 10th, 1860,
 when this mill, in full operation, fell in a moment without
 warning, in an indescribable and utter ruin. On that
 memorable day an observant citizen was walking on Canal
 street at 4.45 o'clock p.m. As he stood before this modern
 mill he saw it outlined against the winter sky, a perfect,
 complete and symmetrical whole. Within its walls, six
 hundred and seventy people were working, each with his or
 her duties, hopes and expectations. . . .He had not gone six
 rods away when there was a roaring sound, a tremor of the
 earth and a simultaneous crash. He turned and saw in
 place of the stately walls that stood but a moment before
 perfect in every outline, only a mass of ruins, shapeless
 and huge, from which bewildered men and women were
 here and there escaping, some unhurt, some wounded and
 bleeding...
 The tidings flew like wildfire throughout the city and,
 without delay a sturdy corps of volunteer mechanics and
 workers, of every occupation, covered the ruins, clearing
 away the debris and rescuing those confined therein.
