When you approach the city, you come along a liquid road, marked by rows of stakes on each side, which direct vessels, of a certain burthen, to avoid the shallows, and keep in deeper water. These shallows are a better defence to the city than the strongest fortifications. On the approach of an enemy’s fleet, the Venetians have only to pull up their stakes, and the enemy can advance no farther. They are equally beyond the insult of a land army, even in the midst of winter; for the flux and reflux of the sea, and the mildness of the climate, prevent such a strength of ice as could admit the approach of an army that way. The lake in which Venice stands, is a kind of small inner gulph, separated from the large one by some islands, at a few miles distance. These islands, in a great measure, break the force of the Adriatic storms, before they reach the Laguna; yet, in very high winds, the navigation of the lake is dangerous to gondolas, and sometimes the gondoleers do not trust themselves, even on the canals within the city. This is not so great an inconveniency to the inhabitants as you may imagine; because most of the houses have one door opening upon a canal, and another communicating with the street; by means of which, and of the bridges, you can go to almost any part of the town by land, as well as by water. The number of inhabitants are computed at about 150,000; the streets, in general, are narrow; so are the canals, except the grand canal; which is very broad, and has a serpentine course through the middle of the city. They tell you, there are several hundred bridges in Venice. What pass under this name, however, are single arches thrown over the canals; most of them paltry enough. The Rialto consists also of a single arch, but a very noble one, and of marble. It is built across the grand canal, near the middle, where it is narrowest. This celebrated arch is ninety feet wide on the level of the canal, and twenty-four feet high. Its beauty is impaired by two rows of booths, or shops, which are erected upon it, and divide its upper surface into three narrow streets. The view from the Rialto is equally lively and magnificent; the objects under your eye are the grand canal, covered with boats and gondolas, and flanked on each side with magnificent palaces, churches, and spires; but this fine prospect is almost the only one in Venice; for, except the Grand Canal, and the Canal Regio, all the others are narrow and mean; some of them have no keys; the water literally washes the walls of the houses. When you sail along those wretched canals, you have no one agreeable object to cheer the sight; and the smell is overwhelmed with the stench which, at certain seasons, exhales from the water.
