Tibetan boots. The direct way to Gumo tang was blocked with snow, so we had to make a detour by the northern and western flanks of the pass. The snow was frozen, and walking became very dangerous. I made my way as best I could, using both hands and feet. The gorge along which we advanced was so deep that the eye tired of following its windings. The snows from the pass supply the headwater of the Yong-dso chu, which runs past the Jongri (la). The descent was even more dangerous than the ascent; my coolies, used to such work, had soon left me far behind.
Leaving the snows of the Du la, we again came in sight of deep gorges filled with pines, with here and there bits of pasture-land overhung by rugged cliffs.
Again we had to cross a spur, beyond which lay Gumo tang, our next halting-place, in a deep gorge, some 2000 feet below us. We followed a glacier, and by six in the evening I reached the beautifully wooded Gumo tang gorge, and found it flooded by a torrent coming from the melting snows to the north-east. On the other side of the precipice which overhangs Gumo tang is Lachmi pokri, "The Lake of Fortune," said to contain gold and precious stones. It is a mile in circumference, deep black in colour, and in its depths are water-elephants, the people say.
November 19.—Crossing a stream, with water knee-deep, flowing eastward to feed the Ratong, we began the ascent of the Bogto la. Firs and junipers of various species overhung our way, which lay along the sides of a dry, glacial channel, with a stream flowing down it, and débris on either side. There are two tracks from here leading to the only shed on the slope of the Bogto; one follows the course of the stream which comes down from the Tso-nag lake, and is usually taken by the Yampung herdmen and the salt traders from Yangma; but the one we followed is not liked by them, as there grows along it a plant called Dug shing,[1] a deadly poison if eaten by yaks or sheep. Pheasants were feeding on the rhododendron berries, and we also saw herds of wild sheep; but before we reached the summit the rhododendrons and junipers disappeared, and we only saw now and then some lichens or moss-like vegetation in the clefts of the rocks.[2]
Reduced for the last few days to a miserable diet of rice and tea,
