Following the banks of the Seine, towards the west, we next come to the

PONT DE LA CONCORDE.

This bridge, which had long been wished for and projected, was begun in 1787, and finished in 1790. Its southern extremity stands opposite to the Palais du Corps Législatif; while that of the north faces the Place de la Concorde, whence it not only derives its present appellation, but has always experienced every change of name to which the former has been subject.

The lightness of its apearance is less striking to those who have seen the Pont de Neuilly, in which PERRONET, Engineer of bridges and highways, has, by the construction of arches nearly flat, so eminently distinguished himself. He is likewise the architect of this bridge, which is four hundred and sixty-two feet in length by forty-eight in breadth. Like the Pont National, it consists of five elliptical arches. The span of the centre arch is ninety-six feet; that of the collateral ones, eighty-seven; and that of the two others near the abutments, sixty-eight. Under one of the latter is a tracking-path for the facility of navigation.

The piles, which are each nine feet in thickness, have, on their starlings, a species of pillars that support a cornice five feet and a half high. Perpendicularly to these pillars are to rise as many pyramids, which are to be crowned by a parapet with a balustrade: in all these, it is intended to display no less elegance of workmanship than the arches present boldness of design and correctness of execution.

On crossing these bridges, it has often occurred to me, how much the Parisians must envy us the situation of our metropolis. If the Seine, like the Thames, presented the advantage of braving the moderate winds, and of conveying, by regular tides, the productions of the four quarters of the globe to the quays which skirt its banks, what an acquisition would it not be to their puny commerce! What a gratification to their pride to see ships discharging their rich cargoes at the foot of the Pont de la Concorde! The project of the canal of Languedoc must, at first, have apparently presented greater obstacles; yet, by talents and perseverance, these were overcome at a time when the science of machinery of every description was far less understood than it is at the present moment.

It appears from the account of Abbon, a monk of the abbey of St. Germain-des-Prés, that, in the year 885, the Swedes, Danes, and Normans, to the number of forty-five thousand men, came to lay siege to Paris, with seven hundred sail of ships, exclusively of the smaller craft, so that, according to this historian, who was an eye-witness of the fact, the river Seine was covered with their vessels for the space of two leagues.

Julius Cæsar tells us, in the third book of his Commentaries, that, at the time of his conquest of the Gauls, in the course of one winter, he constructed six hundred vessels of the wood which then grew in the environs of Paris; and that, in the following spring, he embarked his army, horse and foot, provisions and baggage, in these vessels, descended the Seine, reached Dieppe, and thence crossed over to England, of which, he says, he made a conquest.

About forty years ago, the scheme engaged much attention. In 1759, the Academy of Sciences, Belles-Lettres, and Arts of Rouen, proposed the following as a prize-question: "Was not the Seine formerly navigable for vessels of greater burden than those which are now employed on it; and are there not means to restore to it, or to procure it, that advantage?" In 1760, the prize was adjourned; the memoirs presented not being to the satisfaction of the Academy. In 1761, the new candidates having no better success, the subject was changed.

However, notwithstanding this discouragement, we find that, on the 1st of August, 1766, Captain Berthelot actually reached the Pont Royal in a vessel of one hundred and sixty tons burden. When, on the 22d of the same month, he departed thence, loaded with merchandise, the depth of the water in the Seine was twenty-five feet, and it was nearly the same when he ascended the river. This vessel was seven days on her passage from Rouen to Paris: but a year or two ago, four days only were employed in performing the same voyage by another vessel, named the Saumon.
