ground here, depends on the fact that Serlep yung is situated at the old bed of the Satlej, whereas Chukta-lungfta is on a tributary to the right of the main river. The first 5.5 km. of our road, followed along the left bank of the old bed, which gradually became more and more distinctly cut out in the ground and its erosion terraces became more clearly developed. Sometimes the latter even made the impression of still being under the influence of erosion. Now, the bed contained more water than the previous year, though practically only pools of stagnant rain-water. From the slopes of the hills to the S. W. of the bed, several erosion furrows and ravines came down, joining the Sallej bed, now all of them dry. During and after rain they bring their tribute to the Satlej, the course of which, therefore, becomes regenerated already a short distance west of the threshold and after the interruption of its course by the Rakas-tal. To avoid the tributaries , we cross the bed of the main river, and begin slowly to rise S. W. towards a secondary threshold, leaving to our left the rocky gate by which the Sallej enters into the first of its narrow gorges.

A road to Gyanima coming from Parka and other places, here crosses the .Sallej and leaves the gorge to the right, ascending to another threshold on the left side of the river. The mountains south of the river, were called Arnar. Chuktayogma and Chukta-kongna were said to be transverse valleys in the mountains to

the N. E. of the road to Gartok. Davngong-lungpa is a little valley in the nearest hills to our right. Lamchuger-tsangj5o is a brook, and then Ninchung-lungfta a valley also to our right. Rong-chung was said to be the name of the Sallej gorge. I cannot regard these names as reliable as they were given by the single guide we had and there were no inhabitants or wanderers to ask.

Our road slowly rises to the little, flat threshold, Ninchung--la, with a cairn

at the height of 4,645 m. The ground is traversed by several small furrows going down S. W. to the Sallej, all without water. At Chukta-lungfta, our camp, there was a brook with water, about o.I cub. m. per second. It pierces the rock in a deep-cut gorge down to the Sallej. Only a caravan of sheep on its way to Gyanima, had been seen. Kyangs were grazing here and there. It had rained the whole night as in the afternoon the day before.

On :icly 3 olh, our road goes W. N. W. for I o km., falling to 4,517 m. at Lamp CCCCL VIII, Dölchu -gomma. The fall is 98 m. in this distance or at a rate of I : 102. The road crosses a little insignificant threshold beyond which it goes down to the sharply marked valley of Chukla - kongma. There is some tussock-grass. To the left is a hill called Naga-nakbo. West of the valley, the ground again rises to a very low threshold, after which we have a plain to the south and low hills to the north. The whole country falls southwards to the valley of the .Sallej which is out of sight. Several small beds go down to the

FROM MANASAROVAR TO THE SHIB RIVER.
