Kosdera, where we halted, is a pretty place, elevated 440 feet, with a broad stream front the hills flowing past it. These hills are of limestone, and rounded, resting upon others of hornstone and jasper. Following up the stream I came to some rapids, where the stream is crossed by large beds of hornstone and porphyry rocks, excessively hard, and pitched up at right angles, or with a bold dip to the north. The number of strata was very great, and only a few inches or even lines thick: they presented all varieties of jasper, hornstone, and quartz of numerous colours, with occasional seams of porphyry or breccia. The racks were elegantly fringed with a fern I had not hitherto seen, _Polypodium proliferum,_ which is the only species the Soane valley presents at this season. Returning over the hills, I found _Hardwickia binata,_ a most elegant leguminous tree, tall, erect, with an elongated coma, and the branches pendulous. These trees grew in a shallow bed of alluvium, enclosing abundance of agate pebbles and kunker, the former derived from the quartzy strata above noticed. On the 23rd and 24th we continued to follow up the Soane, first to Panchadurma (alt. 490 feet), and thence to Pepura (alt. 587 feet), the country becoming densely wooded, very wild, and picturesque, the woods being full of monkeys, parrots, peacocks, hornbills, and wild animals. _Strychnos potatorum,_ whose berries are used to purify water, forms a dense foliaged tree, 30 to 60 feet high, some individuals pale yellow, others deep green, both in apparent health. _Feronia Elephantum_ and _Aegle marmelos_* [The Bhel fruit, lately introduced into English medical practice, as an astringent of great effect, in cases of diarrhoea and dysentery.] were very abundant, with _Sterculia,_ and the dwarf date-palm. One of my carts was here hopelessly broken down; advancing on the spokes instead of the tire of the wheels. By the banks of a deep gully here the rocks are well exposed: they consist of soft clay shales resting on the limestone, which is nearly horizontal; and this again, unconformably on the quartz and hornstone rocks, which are confused, and tilted up at all angles. A spur of the Kymore, like that of Rotas, here projects to the bed of the river, and was blazing at night with the beacon-like fires of the natives, lighted to scare the tigers and bears from the spots where they cut wood and bamboo; they afforded a splendid spectacle, the flames in some places leaping zig-zag from hill to hill in front of us, and looking as if a gigantic letter W were written in fire.
