THE TAGRAK-TSANGPO.
t

333
The Buser-tsangpo has to be regarded as piercing the Ngangtse Range in a transverse valley which saves us from crossing this range in a pass.
From Canep CXII, Panorama 12 5 A and B, Tab. 23, is sketched showing the
mountainous region Kapchor to the S. W., Mount Chavez-libo to the N. W., the peak Chao-tokde to the E. N. E. and Porchung to the E. S. E.; to the S. E., south and S. S. W. there is a labyrinth of mountains, though most of them seem to be of a moderate elevation.
On 7anuary 241h, we had 17 km. to Camp CXIII, Kayi-pangbuk. The first
half of this section is directed to the south, the latter half to the S. E. The differences of altitude are insignificant as we pass on undulating ground from the valley of Buser-tsangpo to that of the main river, Tagrak-isangpo. Camp CXII was at 4,959 m., the Tagrak-tsangpo, at the point where we first reached it after 8 km., was 4,914 m., and Camp CXIII 4,93o m. I On the day's march the ground thus first falls and then rises again. Camp CXIII, however, is 29 m. lower than Camp CXII.
On 7anuary 25th, we covered 12.2 km. S. S. E. As Camp CXI V, Nadsum, is
at 4,986 m., the rise from Camp CXIII, is 56 m., or as I : 2 18. The ground rises very gradually in the valley of the Kesar-tsangpo, which is a southern tributary to the Tagrak-tsangpo. The mountains to the east and west are to be regarded as primary or secondary ramifications from the main range Pabla which we are approaching on our road to the S. E.
Just a little bit east of Camp CXIII, I sketched from a low terrace a pano-
rama, 131, Tab. 24, of the broad and open valley of the Kesar- tsangpo and Naong-tsangpo. To the E. N. E. is visible the valley by which the Kung'-tsangpo comes down to join the main river, Tagrak-isangpo. To the S. 7o° E. is a mountainous region called Tsaga. S. S. E. is a region Pupchen.
Panorama I 2 I A, B and c, Tab. 2 2, from Camp CXIV, Nadsum, situated heigher
up on the Kesar-tsangpo, embraces the whole of the horizon. To the N. 70° W. the mountains are called Kokam. To the N. W. the hills have a very moderate, rounded appearance; N. N. E., on the other side of the valley, is Mount Vai. N. 20° E. is the flat group known as Tsag-a, mentioned above. To the N. E. a considerable valley called Goa, opens, indicating the grazing-grounds of the small Gazella antelopes. E. N. E. is a less conspicuous valley, Yakchung, a name indicating the existence of wild yaks in it. Gumcho is a cupola-chaped mountain to the E. S. E. To the S. 56° E. the Naong-sung valley opens out to the plain ; in this valley our road continues to the S. E. S. 35° E. is a more considerable mountain peak with snow, called Pupchen. S. S. E. the Rekur valley comes out, and to the right of it is a
I The figure of 4,910 m. on the map, Pi. 7, is wrong, as mentioned in the meteorological diary, Vol. VI, pl. 34, note.
