I have seen something of the project of M. de St. Pierre, for maintaining a perpetual peace in Europe. I am reminded of a device in a cemetery, with the words: Pax perpetua ; for the dead do not fight any longer: but the living are of another humor; and the most powerful do not respect tribunals at all.
