One morning, near Piolaine, the ground was found cracked above the north gallery of Mirou which had fallen in the day before; and on the following day the ground subsided within the Voreux, shaking a corner of a suburb to such an extent that two houses nearly disappeared.
Un matin, pres de la Piolaine, on trouva le sol fendu au-dessus de la galerie nord de Mirou, éboulée de la veille; et, le lendemain, ce fut un affaissement intérieur du Voreux qui ébranla tout un coin de faubourg, au point que deux maisons faillirent disparaître.
