The Tuileries are certainly very magnificent, and, to walk across from the Seine to the Rue Rivoli, and look up the endless walks and under the long perfect arches cut through the trees, may give one a very pretty surprise for once--but a winding lane is a better place to enjoy the loveliness of green leaves, and a single New England elm, letting down its slender branches to the ground in the inimitable grace of nature, has, to my eye, more beauty than all the clipped vistas from the king's palace to the _Arc de l'Etoile_, the _Champs Elysées_ inclusive. One of the finest things in Paris, by the way, is the view from the terrace in front of the palace to this "Arch of Triumph," commenced by Napoleon at the extremity of the "Elysian Fields," a single avenue of about two miles. The part beyond the gardens is the _fashionable drive_, and, by a saunter on horseback to the _Bois de Boulogne_, between four and five, on a pleasant day, one may see all the dashing equipages in Paris. Broadway, however, would eclipse everything here, either for beauty of construction or appointments. Our carriages are every way handsomer and better hung, and the horses are harnessed more compactly and gracefully. The lumbering vehicles here make a great show, it is true--for the box, with its heavy hammer-cloth, is level with the top, and the coachman and footmen and outriders are very striking in their bright liveries; but the elegant, convenient, light-running establishments of Philadelphia and New York, excel them, out of all comparison, for taste and fitness. The best driving I have seen is by the king's whips, and really it is beautiful to see his retinue on the road, four or five coaches and six, with footmen and outriders in scarlet liveries, and the finest horses possible for speed and action. His majesty generally takes the outer edge of the _Champs Elysées_, on the bank of the river, and the rapid glimpses of the bright show through the breaks in the wood, are exceedingly picturesque.
