_Talawas_.--In these districts of the lowlands, especially on the eastern coast of the island, and in the country watered by the Mahawelli-ganga and the other great rivers which flow towards the Bay of Bengal and the magnificent estuary of Trincomalie, there are open glades which diversify the forest scenery somewhat resembling the grassy patenas in the hills, but differing from them in the character of their soil and vegetation. These park-like meadows, or, as the natives call them, "talawas," vary in extent from one to a thousand acres. They are belted by the surrounding woods, and studded with groups of timber and sometimes with single trees of majestic dimensions. Through these pastures the deer troop in herds within gunshot, bounding into the nearest cover when disturbed. Lower still and immediately adjoining the sea-coast, the broken forest gives place to brushwood, with here and there an assemblage of dwarf shrubs; but as far as the eye can reach, there is one vast level of impenetrable jungle, broken only by the long sweep of salt marshes which form lakes in the rainy season, but are dry between the monsoons, and crusted with crystals that glitter like snow in the sunshine. On the western side of the island the rivers have formed broad alluvial plains, in which the Dutch attempted to grow sugar. The experiment has been often resumed since; but even here the soil is so defective, that the cost of artificially enriching it has hitherto been a serious obstruction to success commercially, although in one or two instances, plantations on a small scale have succeeded to a certain extent. METALS.--The plutonic rocks of Ceylon are but slightly metalliferous, and hitherto their veins and deposits have been but imperfectly examined. The first successful survey attempted by the Government was undertaken during the administration of Viscount Torrington, who, in 1847, commissioned Dr. Gygax to proceed to the hill district south of Adam's Peak, and furnish a report on its products. His investigations extended from Ratnapoora, in a south-eastward direction, to the mountains which overhang Bintenne, but the results obtained did not greatly enlarge the knowledge previously possessed. He established the existence of _tin_ in the alluvium along the base of the mountains to the eastward towards Edelgashena; but so circumstanced, owing to the flow of the Walleway river, that, without lowering its level, the metal could not be extracted with advantage. The position in which it occurs is similar to that in which tin ore presents itself in Saxony; and along with it, the natives, when searching for gems, discover garnets, corundum, white topazes, zircon, and tourmaline.
