GENEVA Lake. This lake is in the shape of a crescent. Switzerland forms the hollow, and Savoy the convex part, the greatest breadth being about twelve miles. The country on the side of Savoy is full of high and craggy mountains; but from Geneva to the environs of Lausanne it slopes to the margin of the lake, and is very rich and fertile. The banks rise considerably in the neighbourhood of Lausanne, and form a most beautiful terrace, with a rapid descent a few miles beyond the town. In the neighbourhood of Vevay a plain begins, and continues for a great way beyond the end of the lake, but is contracted towards the water by the approach of the mountains. The lake itself appears at a distance of a beautiful blue colour, and the water is very clear and transparent. Near Geneva the coast of the lake abounds with pebbles; between that city and Lausanne it is sandy; from thence to Chillon it is bounded by hard calcareous rocks; and the extremity of the shores is a marsh formed by mud collected from the river Rhone. The greatest depth of this lake found by M. de Luc is a hundred and sixty fathoms.
