334 MY FIRST JOURNEY ACROSS THE TRANSHIMALAYA.
region called Lassar. Nearly south is a valley called Tokya, and S. S. W. is Toke-ri. S. W. of the camp is a large valley, Martsu, by which the upper Kesar-tsangpo seems to come down. North of the latter is another valley, without a name, and obviously carrying the upper course of the little brook flowing just west of Kesar-
tsangpo.
On 7anuary 26th, we travelled 15.8 km. E. S. E. At Camp CXV in the
valley of Naong-sung the altitude was 5,134 m., being 148 m. above Camp CXIV; the rise is thus as 1:106.7. In spite of our approaching such an important range as the Pabla the ascent of the ground, from the northern side, is very gradual, proving that the destructive and accumulating powers have accomplished during bygone ages a very energetic work in the Transhimalaya, which on the south borders the Chang-tang or the great plateau-land without an outlet to the sea.
Panorama 129, Tab. 24, does not reach very far around, as Camp CXV, from where it was taken, is situated in a valley. However, some of the mountains we had passed on the previous day were now visible to the N. W.
On 7anuary 27th, we travelled 14 km. S. E. to Camp CXVI in the valley of the Pupchung brook which is at the height of 5,344 m. or 2 I o m. above the preceding camp. The rise is at a rate of i :66.6 showing a somewhat accelerated ascent as compared with the preceding section. Just before reaching the camp we had to cross a little distinctly secondary threshold in a spur of the Pabla Range, at a height of 5,399 m., or only 55 m. above the camp.
From this threshold Panorama 12 7, Tab. 2 3, is drawn. This view is of considerable importance as it gives an idea of one of the water-parting ranges of the Transhimalaya, a watershed of the highest orographical and hydrographical dignity, viz. between the interior, self- contained regions of Central Asia, and the Indian Ocean. The panorama discloses the crest and the peaks of the Pabla Range from N. 2 5 ° E. to the east, south and S. 62° W., where the Pupche raises its snow-covered head. The observation point being at the considerable altitude of 5,399 m. the range makes no imposing impression, and as far as can be seen from here, it has no very high peaks, probably hardly any above 6,500 or 6,700 m. The panorama shows very clearly the saddle of Sela-la between E. and S. 73° E. From S. E. to S. W. there are several peaks covered with some snow. To the south is Pupchung--ri, not entered on the panorama, but appearing on the map, Pl. 7, from which the brook of Camp CXVI comes down.
On 7anuary 28th, we had 16 km. E. S. E. to the great water-parting pass of Sela-la, which has an altitude of 5,506 m. or 162 m. above Camp CXV I, being a rate of ascent as 1 :99. The rise is therefore very gradual. From the pass we had 2.9 km. S. E. to Camp CX VII which was at an altitude of 5,225 m. or 281 m. below the pass. The descent on the southern side is thus very steep, or as 1: 10.3.
