The vegetation in the bottom of the glen showed, as on former occasions, indications of a low elevation, but presented no novelty, except in the occurrence of Melia Azedarach, apparently wild. I have occasionally noticed this tree in the interior of the Himalaya, always at an elevation of between 4000 and 5000 feet, and invariably in the drier valleys of the mountains, but it is so commonly cultivated in India, that its occurrence can scarcely be regarded as a proof of its being indigenous, especially if we consider that it is a rare circumstance to find it in even an apparently wild state. I do not, however, know that it has a greater claim to be considered a native of any part of the world.
SERAHAN.
August, 1847.
The ascent on the east side was long, steep, and fatiguing, up well-wooded slopes. At about 6000 feet, a single tree of Hippophaë conferta, with nearly ripe fruit, was observed near a spring, and a few hundred feet higher the road gained the ridge, and continued for a mile and a half of very gentle ascent, on a broad, nearly level mountain-side, to Serahan, through beautiful forest of oak and pine. Serahan, the summer residence of the Basehir Rajah, is pleasantly situated at an elevation of 7000 feet above the level of the sea, on the northern slope of the mountain range, surrounded on all sides by pine-forest. The village is small, and occupies the lower margin of an open glade of considerable extent, on which there is a good deal of cultivation, of the same plants as I have noted at Kotgarh. The latter part of our march had been through heavy rain, which continued all the evening, and the greater part of the night, but we were fortunate enough to find an empty house, capable of sheltering our servants and baggage, as well as ourselves.
Besides the Hippophaë, which I noted on the ascent from Manglâd, several plants appeared on this day's journey, which served to chronicle a gradual alteration in the flora, notwithstanding that the forest-trees and general character continued generally the same. Of these, the most interesting, by far, was a plant discovered by Mr. Edgeworth, in the same tract of country, and by him described as Oxybaphus Himalayanus, a species of a genus otherwise entirely South American. It is a rank-growing, coarse, herbaceous plant, with tumid joints, and a straggling dichotomous habit, and has small pink or rose-coloured flowers, covered with a viscid exudation. It grows in open pastures and in waste places near villages, and is an abundant species throughout the Kunawar valley.
TRANDA.
August, 1847.
On the morning of the 12th of August we marched to Tranda, along the mountain-side, winding a little with its sinuations, and occasionally descending to cross the little streamlets which furrow its side, and separate the lateral ridges from one another. The road lay through beautiful forest, and as the day was fine we obtained at intervals a succession of superb views, of the deep and well-wooded valleys below, and the rugged mountains north of the Sutlej. The forest-trees were still the hoary and holly-leaved oak, with deodar and spruce, though in the more shady woods along the streams, the horse-chesnut, and a fine glaucous-leaved laurel, were common. The shrubby and herbaceous vegetation was in general character the same as in the denser woods of Simla, the new species being still quite exceptional.
It soon became necessary to descend, in order to gain a place on the next range in succession to the eastward, so as not to leave the river at too great a distance. Forest continued to the bottom of the descent, which showed no signs of tropical vegetation, and was therefore not to so low a level as those of previous days. The remainder of the day's journey consisted of a succession of ascents and descents, mostly long and fatiguing, with occasionally half a mile nearly level. Many of the steeper parts were very rocky and rugged, so difficult that artificial steps were required to make them practicable, and even with their aid a horse could scarcely pass. The greater part of the road lay through forest, and two considerable streams were crossed besides the one on the early part of the march. From the last of these a long and very laborious ascent led to the crest of the Tranda ridge, on the very top of which we halted for the night in a log hut, built for the accommodation of travellers, in the midst of a fine forest of deodar-trees.
The Tranda ridge has, till near its termination, an elevation of upwards of 8000 feet, and projects boldly forward towards the Sutlej, dipping at last extremely abruptly to the river. The Sutlej is here thrown to the north, in a sharp bend, and runs through a deep gloomy ravine. This ridge, therefore, more lofty and abrupt than any farther west, is considered as the commencement of Kunawar; and the valley to the eastward, as far as the Wangtu bridge, is generally called Lower Kunawar, to distinguish it from the upper and drier parts of that district. The rise of the bed of the river is so gradual, that the transition of climate takes place at first by almost insensible gradations; but as soon as the spurs retain a height of 8000 feet till close to the Sutlej, they exercise a powerful influence upon the climate, and the vegetation and physical aspect of the country change with great rapidity.
