The descent was very abrupt on the first day, from 9,500 feet to 5000 feet, and on that following to the bed of the Pemmi, at 2000 feet; and the road was infamously bad, generally consisting of a narrow, winding, rocky path among tangled shrubs and large boulders, brambles, nettles, and thorny bushes, often in the bed of the torrent, or crossing spurs covered with forest, round whose bases it flowed. A little cultivation was occasionally met with on the narrow flat pebbly terraces which fringed the stream, usually of rice, and sometimes of the small-leaved variety of hemp (_Cannabis_), grown as a narcotic. The rocks above 5000 feet were gneiss; below this, cliffs of very micaceous schist were met with, having a north-west strike, and being often vertical; the boulders again were always of gneiss. The streams seemed rather to occupy faults, than to have eroded courses for themselves; their beds were invariably rocky or pebbly, and the waters white and muddy from the quantity of alumina. In one little rocky dell the water gushed through a hole in a soft stratum in the gneiss; a trifling circumstance which was not lost upon the crafty Brahmins, who had cut a series of regular holes for the water, ornamented the rocks with red paint, and a row of little iron tridents of Siva, and dedicated the whole to Mahadeo. In some spots the vegetation was exceedingly fine, and several large trees occurred: I measured a Toon (_Cedrela_) thirty feet in girth at five feet above the ground. The skirts of the forest were adorned with numerous jungle flowers, rice crops, blue _Acanthaceae_ and _Pavetta,_ wild cherry-trees covered with scarlet blossoms, and trees of the purple and lilac _Bauhinia_; while _Thunbergia, Convolvulus,_ and other climbers, hung in graceful festoons from the boughs, and on the dry micaceous rocks the _Luculia gratissima,_ one of our common hot-house ornaments, grew in profusion, its gorgeous heads of blossoms scenting the air. At the junction of the Pemmi and Khawa rivers, there are high rocks of mica-slate, and broad river-terraces of stratified sand and pebbles, apparently alternating with deposits of shingle. On this hot, open expanse, elevated 2250 feet, appeared many trees and plants of the Terai and plains, as pomegranate, peepul, and sal; with extensive fields of cotton, indigo, and irrigated rice. We followed the north bank of the Khawa, which runs westerly through a gorge, between high cliffs of chlorite, containing thick beds of stratified quartz. At the angles of the river broad terraces are formed, fifteen to thirty feet above its bed, similar to those just mentioned, and planted with rows of _Acacia Serissa,_ or laid out in rice fields, or sugar plantations.
