304 FROM MANASAROVAR TO THE SHIB RIVER.
Packen and Packung, enter the lagoon from the north, and their water leaves it to
the south and forms an affluent to the Manasarovar. The joint river now had , at the place where we crossed it, a breadth of exactly i oo m., an average depth of
0.15 m. and an average velocity of 0.35 m. The volume of water amounted to 5.25 cub. m. per second. The water was nearly clear, the bed consisted of sand and silt, partly very soft, as the animals sank deep into it.
We then followed the narrow neck of land between the lake and the lagoon. It is a terrace with slopes on both sides. Along the very edge of the lake, there
is a series of very small lagoons which will be inundated during years with an outflow to Rakas - tal. Mount Pundi was in sight the whole day, Gurla - mandata was hidden by clouds, and Kailas got rid of its clouds towards evening. Cane CCCCLIII was pitched on the left bank of the little river Gyuma-chu, on the right side of which the monastery of Lang6o-nan-goiizpa was situated. At our camp the little river was now 12.41 m. broad, its average depth being 0.39 m., and its average velocity 0.83 m., the volume of water was 4.014 cub. m. per second.
On .uly 26th, we travelled along the shore to Chiu-gompa, passing Chärgip(ompa on the way. It was the same road as in i 907 (Cp. Pl. i 2). The next day we continued N. W. at some distance north of the bed, from Manasarovar to Rakas-tal and near the latter lake, entered ground that was new to me. It was slightly undulated, partly barren but north of the lake very rich in excellent grass, where the inhabitants of Parka use to have their flocks in winter. Mount Kailas seemed to be a little more snow-covered than the previous year.
On 7uly 28th, we continued across the grass steppe, crossing the river which comes down from the Kailas and surrounding mountains. A Tibetan called it Toanhle-Machu, which, however, seems doubtful. It is obviously formed by the two rivers which come down on each side of the Kailas, the eastern being called Dopchenchaz, the western, Hlachu-chu. According to Ryder's map, Sheet No. 14 S. W., two rivers from the mountains to the N. N. E., join just a little above Parka. These two rivers are obviously identical with the two I surveyed on the Kailas. It enters the Rakas-tal at about the middle of its northern shore. I made an approximate calculation of its volume of water, the breadth being i 2 5 m., the average depth 0.3 m. and the average velocity 0.4 m. The volume would thus be about i 5 cub. m. per second, which may be considered as a large affluence. Another much smaller affluent from the north, which also is to be found on Ryder's map, may come from Khaleb. This, however, I cannot make out, as I have not followed the course of these rivers up to the mountains north of the lake, from which they come. On Pl. 12 it will be seen that I, in i 907, crossed the same river higher up and west of Parka. On my way from Parka to Khaleb, I crossed two watercourses, Sung-chu and Lashu (Hlachu `)) which seem to correspond to the two rivers on each
