ALONG THE UPPER TSANGPO TO THE MANASA tOVAfi.

   

On 7une t 7th, we had first 7 km. W. S. W. to Särchung-la, 5,188 m. high, or 459 m. above Konak. The rate is thus i : 15. On the other side we had 12.5 km. S. W and west to Camp CLXXVIII, Dambok-rong, 4,657 m. high, or

a descent of 531 m. from the pass, being a rate of i : 23.5. From Särchung-la Pan. 228, Tab. 41, was drawn, showing to the N. E. some of the magnificent Lunpogangri peaks, and a group of mountains to the E. N. E. also belonging to the same system and being the S. E. continuation of the Lunkar Range. To the S. W. and W. S. W. on Pan. 229, Tab. 42, we have also a fine view of the water-parting Himalaya Range south of the great Tsangpo.

Pan. 2 2 3A and B, Tab. 4o, from Damôok-rong gives an idea of the mountains all around the place. S. 66° E. is the valley by which we arrived. S. 53° W., and round the corner, our road proceeds to Tradum.

The next march, 7une i 8th, takes us 12.1 km. west to Tradum, 4,591 m.

high, or a descent of 66 m., at I : 183. From a point a few kilometers east of Tradum, at a »hla» near the base of a northern rocky promontory, Pan. 2 2 4A and B, Tab. 41, was drawn, showing comparatively low hills, but many names. The word Tasang S. S. E. is obviously no name, but simply tasang or tasam, the great road.

From Tradum itself Pan. 2 2 5A and B and Pan 227, Tab. 41, were drawn, all three belonging together without interruption. From S. 2 I ° W. to S. 58° W. they show a considerable snowy range, the water-parting Himalaya. Just in front of this range and turning to the left, we had to travel towards S. 21° W. the next days. To the N. 67° W. is the valley of the great Tsangpo. To the N. 4o° W. is the valley of the Tsa-chu-tsangpo. To the N. E. is the monastery of Tradum and to the S. E. a solitary chorten. This panorama was taken some Boo meters west of the camp.

On 7une 20th, our road goes due south for 10.6 km. to the Tsangpo, or Upper Brahmaputra, at Liktse-gompa where the altitude is 4,565 m. or 26 m. below Tradum, a rate of fall of I:408. Here the Tsa-chu-tsangpo comes in from the N. W. From this place Pan. 23 1 A and B, Tab. 42, was drawn to show the entire horizon. To the N. W. is the broad, open valley of the Tsangpo. N. 6o° E. the Tsangpo turns to the east. N. 76° E. is the hill of Liktse with its gompa, also seen on a photo between p. 318 and 319 of Vol. II, and S. 68° W. is the Peak Rungona.

On Tune 2 ist, we travelled 33.8 km. S. W. and south to Camp CLXXXI where the altitude is 4,595 m., or 3o m. above Camp CLXXX on the Tsangpo. The rise is, therefore, extremely gradual, or as I : 1127. In the first section of this road the low thresholds, Tsasa-la, Dorap-la and Ngurkung--la were crossed. From the second of these Pan. 23o, Tab. 42, was sketched showing the third threshold, Ngurkung-la to the S. 33° W., and to N. 88° W. Dikpa-nakchir, a small peak, at the western side of the broad entrance to the JVachalak Plain. The Pan. 237, Tab. 43, from Camp CLXXXI is interesting so far as it gives an idea of the
