296 OUR JOURNEY TO CHUNIT-TSO.
4,805 m., being a rate of i :55. The minimum temperature was —14.1°. The S. W. wind was fresh at 1 o'clock p. m. and the sky cloudy, though the clouds were thin and white. The evenings and nights were usually clear.
The valley by which we now continue S. S. W., has a little brook and large ice-sheets. It is hydrographically to be regarded as a tributary from the left, to the brook we had followed down from Ladung-la. The latter brook increases in volume, by and by, as it receives many contributions from springs. Finally it turns W. S. W., and perhaps N. W. to a little lake situated west of the hills. In its lower part, where the bed is broad, shallow and exposed, it does not contain fish. In its upper reaches,
it is narrow, sometimes i or 2 m. only, and deep, sometimes ¢ m., and the banks 11
grass-covered and overhanging; there the fish are more protected.
The bottom of the valley is swampy and there is tussock-grass. Three sheepfolds were passed. At a narrow place the living rock was reddish grey porphyrite. Beyond this narrow passage, the valley again opens out to a plain between the mountains. The bed with the ice, seems to come from a comparatively high mountain to the S. E. where ice is seen in a valley. West of our route, two small, dry clay depressions are left. The surrounding hills are reddish yellow and of moderate size. In the neighbourhood of a lonely tent where snow was still left, we pitched our Camp CCCLXIX.
The information given us here agreed well with what we had heard before, and seemed to be reliable. The pass to the S. S. W., was called Salsol-la, and the lake beyond it, Chunil-lso. Five days' journey west, was the salt lake, Tabie-isaka, the distance probably calculated from the rate of the march of sheep caravans, as it is, indeed, only 45 km. Bongba-changma was said to be north of Sangchen-la, Bongba-hloma on the Buplsang-isango, and Bongba-numa at Tabie-isaka. As to Bongba-sherrna, it was placed in the region of Tsongpun Tashi, who had himself given us the name Kung-sherya of his district. Pan. 449A and B, Tab. 84, is of interest. S. 2 5° W. is the valley leading up to the pass, Salsol-la. To the west, comparatively high ridges hide the view in the direction of Tabie-isaka. N. 3o° E., Sha-kanå sham is again visible like a lighthouse above the stone waves of the highland sea. To the N. 6o-68° E., the configuration of the ranges indicate a depression in which a lake may be situated, a matter that remains unsettled, as this part of Tibet has never been visited by a European. This depression is bounded on the N. E. by a distant range of a light blue colour and with two or three snow - peaks, which may belong to the same orographical system as Sha-kangsham.
On Aftril Isl, our direction is S. S. W. for 9.8 km. We had 2 km. to Salsol-la, 4,856 m. high, the rise thus being 5 I m. or at a rate of i : 39. From the pass to Camp CCCLXX at 4,747 m., we had 7.8 km. and a fall of 109 m., being a rate of i : 72. The minimum temperature was only —7.8°, the day somewhat windy and
