The distribution of lake-dwellings in Italy is confined to the Po Valley, and as the course of the river is practically from west to east, it is convenient in describing its chief lacustrine remains to follow the order thus suggested, more especially as those in the eastern portion of the basin have certain characteristics which are not found in those of Western Lombardy. Accordingly we begin with Lake Varese, the settlements of which appear to have been the most important among the western group.
Lake Varese.
Lake Varese is irregularly shaped, about 5^ miles in length, and less than half that in breadth. It occupies a somewhat shallow basin, its greatest depth being 85 feet, and, although bounded on the north by high hills, its banks are generally flat or shelving. Its surface is 770 feet above sea-level, and 134 feet above that of Lake Maggiore, to which its surplus water is carried by the Bardello, a stream which has its outlet at the north end of the lake. The district around is rich and well cultivated, except on the south side, where the lake becomes contiguous with an extensive peat-bog, called "torbiera della Brabbia." When Stoppani and his illustrious friends, along with Desor's experienced fisher, Benz, commenced their lacustrine explorations in Lombardy, they selected Lake Varese to start with, on account of the suitability of its shores for such
