grace of the Ponte Santa Trinita with its moss-grown escutcheons and aerial curves; the Pont Neuf, at Paris, with its soldiers and priests, its boot-blacks and grisettes, the gay streets on one side and the studious quarter on the other, typifies and concentrates for him the associations of the French capital; and what a complete symbol of Venice--its canals, its marbles, its mysterious polity, its romance of glory and woe--is a good photograph of the Bridge of Sighs! The history of Rome is written on her bridges. The Ponte Rotto is Art's favorite trophy of her decay; two-thirds of it has disappeared; and the last Pope has ineffectively repaired it, by a platform sustained by iron wire: yet who that has stood thereon in the sunset, and looked from the dome of St. Peter's to the islands projected at that hour so distinctly from the river's surface, glanced along the flushed dwellings upon its bank, with their intervals of green terraces, or gazed, in the other direction, upon the Cloaca of Tarquin, Vesta's dome, and the Aventine Hill, with its palaces, convents, vineyards, and gardens, has not felt that the Ponte Rotto was the most suggestive servatory in the Eternal City? The Ponte Molle brings back Constantine and his vision of the Cross; and the statues on Sant' Angelo mutely attest the vicissitudes of ecclesiastical eras. England boasts no monument of her modern victories so impressive as the bridge named for the most memorable of them. The best view of Prague and its people is from the long series of stone arches which span the Moldau. The solitude and serenity of genius are rarely better realized than by musing of Klopstock and Gessner, Lavator and Zimmermann, on the Bridge of Rapperschwyl on the Lake of Zurich, where they dwelt and wrote or died. From the Bridge of St. Martin we have the first view of Mont Blanc. The Suspension Bridge at Niagara is an artificial wonder as great, in its degree, as the natural miracle of the mighty cataract which thunders forever at its side; while no triumph of inventive economy could more aptly lead the imaginative stranger into the picturesque beauties of Wales than the extraordinary tubular bridge across the Menai Strait. The aqueduct-bridge at Lisbon, the long causeway over Cayuga Lake in our own country, and the bridge over the Loire at Orleans are memorable in every traveller's retrospect.
