In the valley of Lipa I met with a species of caper, apparently the same which I had collected at Rampur on the Sutlej, on hot rocky places close to the river, but which had not been met with in the intermediate parts of the journey. This little prickly shrub I afterwards found to be a common Tibetan plant, which (like most of its tribe) prefers the hottest and driest exposures, expanding its large white blossoms on dry stony ground, or among rocks where hardly any other plant will vegetate.
Lipa is situated at no great distance from the Sutlej, at an elevation of 8000 feet above the level of the sea. The next range to the eastward is that of Runang, separating the Lipa valley from that of the Ruskalan, on which is situated the village of Sungnam. As in the former instance, we divided the passage into two days' journey, encamping on the 20th of August at an elevation of 12,500 feet. The road began to ascend as soon as we left Lipa. At first we took the direction of the stream, gradually rising along the face of a rocky hill composed of a dark clay-slate, which had now taken the place of the gneiss of the lower part of the Sutlej; but turning to the left, to ascend the ridge, as soon as its crest had been gained. The surface was everywhere barren and dried up. A few scattered pine trees occurred at intervals, but nothing approaching to forest, and the parched stony ground was quite destitute of any covering of turf or of herbaceous vegetation in sufficient quantity to attract the notice of the general observer. The ascent on the ridge was steep and uninterrupted; but as the general direction of the day's journey was down the range, or towards the Sutlej, we had to pass from one ridge to the next in succession, across the ravine by which the two were separated. Here the road was nearly level, and took a long curve in the receding hollow of the hill, turning round a belt of green which occupied the middle of the hollow.
On the left hand, above the road, there was not a trace of verdure in the ravine; but just below the road a small spring burst out from the stony ground. For three or four yards the banks of the little streamlet were quite bare, but at about that distance from its source they were fringed with luxuriant marsh plants, Veronica Beccabunga and Anagallis, rushes, and several kinds of grasses, which gradually increased in abundance. Within a hundred yards of its origin a thicket of willows bordered the stream, and a rich vegetation grew under their shade. From this it would appear that the barrenness of the country cannot be ascribed to any fault of temperature or of altitude, but solely to the deficiency of moisture.
ASCENT TOWARDS THE RUNANG PASS.
August, 1847.
On the next ridge beyond this little green spot, the ascent continued steep, over loose shingly soil, among scattered trees of deodar, and occasionally a fine tree of Pinus Gerardiana; a spinous Astragalus, and several species of Artemisia, formed almost all the scanty vegetation. Higher up there was, in one place, a good view of the Sutlej to the south-east, with a very lofty snowy mountain beyond. A little further on, the pines ceased to grow, and no tree but juniper was seen, the vegetation becoming more and more wretched in appearance, though the same Astragalus and Artemisiæ predominated. Above 12,000 feet, two or three alpine species made their appearance; these were a Polygonum, a Mulgedium, and a little shrubby Potentilla. Except these, however, not one of the numerous alpine forms observed on the Werang pass two days before were to be seen.
We encamped at an elevation of 12,500 feet on the north-east slope of the ridge, overhanging a deep wide valley, in which there were several patches of cultivation still green, at an elevation which I estimated at about 1000 feet below the level of our tents. By this wide valley, (in the lower part of which, on its east side, is the village of Kanam,) we were still separated from the central range on which the Runang pass is situated. The hills all round had a desolate aspect. They were rounded in outline, and appeared quite smooth and destitute of herbage, excepting large dark-green patches of juniper, by which they were mottled. A single stunted tree of Pinus excelsa stood within a short distance of our encampment, and four or five hundred feet lower was a small grove, apparently of birch. During the afternoon a furious west wind blew without intermission. The morning had been quite calm, but before noon the wind had begun to blow, and gradually increased in violence till late in the afternoon; after dark it became calm.
The next morning was clear, with scarcely any wind, but the mountains above us were partly shrouded in mist. For the first time during our journey we had Zobos furnished for the conveyance of our tents. These animals, which are mules between a Yak bull and Indian cow, are intermediate between the two, having most of the peculiarities by which the Yak is distinguished, though in a much less degree. Their colour varies much,—black, white, and iron-grey being all common. They have coarse long shaggy hair, much shorter than in the Yak, a stout rounded body, and the tail has a small tuft at the end, quite similar in miniature to that of the Yak. These mules are exceedingly common in Upper Kunawar and Hangarang, and are much preferred as beasts of burden to the Yak, being more docile, and less sensitive to climatic influences.
THE RUNANG PASS.
August, 1847.
The first half-mile of the ascent to the pass was very gentle, till we passed round the hollow of the valley which lay below our encampment. The hill-sides were covered with stones, among which grew a few tufts of thyme, a large-leaved saxifrage, a yellow Scorzonera, a curious Polygonum, and an Oxyria, the same in appearance with that of the Alps of Europe. Two or three little rills of water trickled across the road, but their margins had no trace of green. The remainder of the ascent was more rapid, but nowhere fatiguing, and I reached the top about 9 A.M. Nothing can be conceived more dreary and bare than the aspect of the pass and the mountains all around. The hills, which at a distance appeared smooth and rounded, were now seen to be covered with loose stones piled upon one another, in the crevices of which a few plants found an attachment for their roots. The elevation was about 14,500 feet, but there was no appearance of snow. To the north-east a wide and straight valley ran from the crest, at the end of which, far below and perhaps eight miles off, was seen the village of Sungnam, beyond which another lofty range of equally rounded mountains, apparently smooth, ran parallel to that on which I stood. On this range, at a level, to the eye sensibly the same as that of the Runang pass, an evident track indicated the pass of Hangarang, over which lay the continuation of our journey.
