world, over the yellow Tiber: as familiar on the Chinese tea-caddy as on Canaletto's canvas; as traditional a local feature of London as of Florence; as significant of the onward march of civilization in Wales to-day as in Liguria during the Middle Ages. Where men dwell and wander, and water flows, these beautiful and enduring, or curious and casual expedients are found, as memorable triumphs of architecture, crowned with historical associations, or as primitive inventions that unconsciously mark the first faltering steps of humanity in the course of empire: for, on this continent, where the French missionary crossed the narrow log supported by his Indian convert in the midst of a wilderness, massive stone arches shadow broad streams that flow through populous cities; and the history of civilization may be traced from the loose stones whereon the lone settler fords the water-course, to such grand, graceful, and permanent monuments of human prosperity as the elaborate and ancient stone bridges of European capitals. When we look forth upon a grand or lovely scene of Nature,--mountain, river, meadow, and forest,--what a fine central object, what an harmonious artificial feature of the picture, is a bridge, whether rustic and simple, a mere rude passage-way over a brook, or a curve of gray stone throwing broad shadows upon the bright surface of a river! Nor less effective is the same object amid the crowded walls, spires, streets, and chimney-stacks of a city. There the bridge is the least conventional structure, the suggestive point, the favorite locality; it seems to reunite the working-day world with the freedom of Nature; it is perhaps the one spot in the dense array of edifices and thoroughfares which "gives us pause." There, if anywhere, our gaze and our feet linger; people have a relief against the sky, as they pass over it; artists look patiently thither; lovers, the sad, the humorous, and the meditative, stop there to observe and to muse; they lean over the parapet and watch the flowing tide; they look thence around as from a pleasant vantage-ground. The bridge, in populous old towns, is the rendezvous, the familiar landmark, the traditional nucleus of the place, and perhaps the only picturesque framework in all those marts and homes, more free, open, and suggestive of a common lot than temple, square, or palace; for there pass and repass noble and peasant, regal equipage and humble caravan; children plead to stay, and veterans moralize there; the privileged beggar finds a standing-place for charity to bless; a shrine hallows or a sentry guards, history consecrates or Art glorifies, and trade, pleasure, or battle, perchance, lends to it the spell of fame. Let any one recall his sojourn in a foreign city, and conjure to his mind's eye the scenes, and prominent to his fancy, distinct to his memory, will be the bridge. He will think of Florence as intersected by the Arno, and with the very name of that river reappears the peerless
