ON the thirteenth of May, 1770, Paris celebrated the wedding of the Dauphin or Prince Royal Louis Aguste, grandson of Louis XV. still reigning, with Marie-Antoinette, Archduchess of Austria. The entire population flocked towards Louis XV. Place, where fireworks were to be let off. A pyrotechnical display was the finish to all grand public ceremonies, and the Parisians were fond of them although they might make fun. The ground was happily chosen, as it would hold six thousand spectators. Around the equestrian statue of the King, stands were built circularly to give a view of the fireworks, to be set off at ten or twelve feet elevation.
