hills, and flowing eastward through the native state of Palanpur, fall into the Runn of Cutch. The Sabarmati and the Mahi rise in the Mahi Kantha hills, and flowing southwards, drain the districts of Northern Gujarat, and fall into the sea near the head of the Gulf of Cambay. The streams which, rising in the Sahyadri range, or Western Ghats, flow westward into the Arabian Sea, are of little importance. During the rains they are formidable torrents, but with the return of the fair weather they dwindle away, and during the hot season, with a few exceptions, they almost dry up. Clear and rapid as they descend the hills, on reaching the lowlands of the Konkan they become muddy and brackish creeks. The Kanarese rivers have a larger body of water and a more regular flow than the streams of the Konkan. One of them, the Sharawati, forcing its way through the western ridge of the Ghats, plunges from the high to the low country by a succession of falls, the principal of which is 800 ft. in height. The Sahyadri, or Western Ghats, also throw off to the eastward the two principal rivers of the Madras Presidency, the Godavari and the Kistna. These rivers collect countless tributary streams, some of them of considerable size, and drain the entire plain of the Deccan as they pass eastward towards the Bay of Bengal. Lakes. The Manchar Lake is situated on the right bank of the Indus. During inundations it attains a length of 20 m., and a breadth of 10, covering a total area estimated at 180 sq. m. But the most peculiar lacustrine feature of the presidency is the Runn or Lake of Cutch, which, according to the season of the year, is a salt marsh, an inland lake, or an arm of the sea with an area of 8000 sq. m. It forms the western boundary of the province of Gujarat, and when flooded during the rains unites the Gulfs of Cutch and Cambay, and converts the territory of Cutch into an island. _Geology._--South of Gujarat nearly the whole of Bombay is covered by the horizontal lava flows of the Deccan Trap series, and these flows spread over the greater part of the Kathiawar peninsula and extend into Cutch. In Cutch and Kathiawar they are underlaid by Jurassic and Neocomian beds. The Jurassic beds are marine and contain numerous Ammonites, but the beds which are referred to the Neocomian include a series of sandstones and shales with remains of plants. Several of the plants are identical with forms which occur in the upper portion of the Gondwana system. Tertiary limestones, sandstones and shales overlie the Deccan Trap in Cutch, but the greatest development of deposits of this age is to be met with on the western side of the Indus (see SIND). The plain of Sind and of eastern Gujarat is covered by alluvium and wind-blown sand.
