[Footnote 1: The Champ de Mars was the scene of the famous "fête de la fédération," which took place in 1790, on the 14th of July, the anniversary of the taking of the Bastile; when the king, the representatives of the people, and the other public functionaries, the commandant of the National Guard, and delegates sent from each of the eighty-three departments of the kingdom, took an oath to preserve the new constitution. A splendid altar, called "l'autel de la patrie," was erected in the middle of the field, around which was an amphitheatre which held four hundred thousand spectators; in the centre of this was the throne of the king. All the people of Paris assisted in making these preparations, that they might be completed by the appointed time. The Bishop of Autun (Talleyrand) was the ministering flamen of the solemnities. At the celebration an incident occurred, illustrating the far seeing sagacity of this man, who thus early discerned the frail and transient nature of that constitution, which its founders had decreed should be "une, indivisible, et impérissable." Lafayette, as commandant of the National Guard, was the first to take the oath; and as he approached the altar for that purpose, Talleyrand in an under tone exhorted him to keep his countenance and not to laugh! thus indicating that he considered the whole scene a solemn farce. I had this anecdote from an American lady to whom Lafayette told it.] I found as I had expected, these embankments covered throughout their whole extent with an innumerable crowd, eager at once to behold the spectacle and to convince the king that Frenchmen could be silent when there was an occasion for it, however unnatural the restraint. I found also the troops to be reviewed, twenty-five thousand in number, drawn up in beautiful array, and arranged on the plain between the embankments, in separate divisions, according to their various designations; the whole forming two lines looking to the centre of the field, and of course facing each other. Here were the famed Cuirassiers, arrayed in triple steel--each one looking the impersonation of war--men and horses forming a dense, motionless, terrific mass. There, were the "Chevaux-légers," less imposing in appearance, but dazzling the eye by the brilliancy of their dress and the rapidity of their evolutions. On one side frowned the "Sappeurs Pompiers," with their ample caps of black fur, their white leather aprons, their glittering axes, their grim moustaches, and beards like Egyptian sheiks. On the other were displayed the regular infantry, with their brilliant pieces and bristling bayonets, at whose points they had so often compelled victory. The elder superior officers were conversing in groups--while the younger paid court to the ladies; whose nodding plumes and wreathed smiles were displayed in covered stages erected temporarily for the purpose, and arranged at the inner foot of the embankment on either side of the field.
