belong to the last-mentioned range. The mountains to the S. S. W., S. W. and
W. S. W., amongst them the Gangchen and Gangchung, seem to form a special
range east of the north-western part of the Ding-la Range.

On July 6th, we travelled 13.6 km. W. N. W. down the Lavar-tsangpo to
Camp CCCCXLIV, Kelle, at an altitude of 4,949 m., the fall thus being 99 m.
and the rate 1:137. To the S. W. and N. W. from here, Pan. 539, Tab. 102, shows
some conical peaks of moderate elevation.

The next day our march continued westwards for 13 km. to Camp CCCCXLV,
in the upper valley of the Aong-tsangpo, and at an altitude of 5,196 m., the rise
thus being 247 m. at a rate of 1:53. From a point 4.5 km. east of the camp,
Pan. 541, Tab. 103, was drawn. To the N. 81° W., N. 60° W., N. 44° W., N. 33° W.,
N. 23° W. and N. 14° W. it shows irregular ridges and peaks of no very considerable
elevation, amongst them the Ra-taon, the Lungnak, the Tokchung and the Tok-
marbo, the latter in the direction of Damrap-tso, to which the Lavar-tsangpo and
the Aong-tsangpo stream. These mountains and peaks are situated between my
route to and beyond the source of the Indus, and the route dealt with at present.
The intermediate region, which has been crossed by Nain-Sing, has no high moun-
tains, and those existing seem to be less regular than those described in the central
regions of the Transhimalaya.

The next day, July 8th, we crossed the Ding-la Range. The direction is
S. S. W. We had 6.6 km. to the pass Ding-la or Chargo-ding-la, 5,885 m. high.
The rise is here 689 m. and the rate 1:9.6. On the southern side we had 9.8 km.
to Camp CCCCXLVI, Luma-nakpo, at an altitude of 5,138 m., a fall of 747 m.,
at a rate of 1:13. Pan. 542, Tab. 103, taken from the pass, shows to the S. E.,
considerable mountains, one of them called Shiri-marmo. To the S. S. E., south
and S. W. are ridges and moderate peaks belonging to the Surnge Range. Due
south, Argok-tso is visible.

On July 9th, we had 12.7 km. S. S. W. to a secondary pass, 5,233 m. high,
the rise being 95 m. and the rate 1:134. On the western side we had 4.6 km.
W. S. W. to Camp CCCCXLVII on the Surnge-chu where the altitude is 5,155 m.
The fall is there 78 m. and the rate 1:59. From the little threshold, Pan. 543A
and B, Tab. 103, was drawn, showing to the N. E. and E. N. E. considerable parts
of the Ding-la Range, and to the S. E. a part of Argok-tso. The mountains south
of the lake were hidden by clouds and snow.

On July 10th, our road proceeded W. S. W. for 22.2 km. up the Surnge-chu
valley to Camp CCCCXLVIII, Takche, where the altitude is 5,281 m., or a rise
of 126 m. and a rate of 1:176. The gradient is, therefore, very gradual. On
July 12th, we even had to go down a few meters to reach the continental water-
parting in the Surnge-la which is so flat that it is impossible to tell its exact
