A long line of islands completely shelters Venice from the sea, so that the waters around its walls are very seldom ruffled into waves. The tide also rises and falls but little, not more than two or three feet, if so much. Thus no banks of pestiferous mud are laid bare at low water by the ebb and flow, and yet some slight circulation is maintained in the canals, which, were it not for this, would be as intolerable as cesspools. Small boats can find their way over most parts of the lagoon, where in many places a safe route has to be marked out with stakes, but for large vessels the channels are few. A long island, Malamocco by name, intervenes between Venice and the Adriatic, on each side of which are the chief if not the only entrances for large ships. At its northern end is the sandy beach of the Lido, a great resort of the Venetians, for there is good sea-bathing. But except this, Malamocco has little to offer; there is more interest in other parts of the lagoon. At the southern end, some fifteen miles away, the old town of Chioggia is a favorite excursion. On the sea side the long fringe of narrow islands, of which Malamocco is one, protected by massive walls, forms a barrier against the waves of the Adriatic. On the land side is the dreary fever-haunted region of the _Laguna Morta_, like a vast fen, beyond which rise the serrate peaks of the Alps and the broken summits of the Euganean Hills. The town itself, the Roman Fossa Claudia, is a smaller edition of Venice, joined like it to the mainland by a bridge. If it has fewer relics of architectural value it has suffered less from modern changes, and has retained much more of its old-world character. Murano, an island or group of islands, is a tiny edition of Venice, and a much shorter excursion, for it lies only about a mile and a half away to the north of the city. Here is the principal seat of the workers in glass; here are made those exquisite reproductions of old Venetian glass and of ancient mosaic which have made the name of Salviati noted in all parts of Europe. Here, too, is a cathedral which, though it has suffered from time, neglect and restoration, is still a grand relic. At the eastern end there is a beautiful apse enriched by an arcade and decorated with inlaid marbles, but the rest of the exterior is plain. As usual in this part of Italy (for the external splendor of St. Mark's is exceptional) all richness of decoration is reserved for the interior. Here columns of choice stones support the arches; there is a fine mosaic in the eastern apse, but the glory of Murano is its floor, a superb piece of _opus Alexandrinum_, inlaid work of marbles and porphyries, bearing date early in the eleventh century, and richer in design than even that at St. Mark's, for peacocks and other birds, with tracery of strange design, are introduced into its patterns.
