the altitude is 4,756 m.; in the valley below, 4,692 m. Here we have a new view
of the *Tarok-tso*, and to the north or N. N. E. the neck of land between the two
lakes. To the east and S. E. is the range to the right of the *Buptsang* valley.
To the S. 55° E. is *Tengi-niguk*, belonging to the latter range. *Malung-gangri*
is still visible. In the foreground, to the S. E. is *Lunkar-gompa* itself. To the
N. 27° E. there is one or perhaps two islands in the *Tarok-tso* near its northern shore.

On *June 10th*, we had an interesting march up the *Lunkar* valley W. S. W.
and S. W. for 9.7 km. to *Lunkar-la*, 5,570 m. high. The rise from *Camp CCCCXXIV*
was, therefore, no less than 783 m., and the rate 1:12.4. On the other side we
had 3.4 km. S. W. and W. S. W. to *Camp CCCCXXV, Goang-shung*, 5,349 m.
high, a fall of 221 m. and a rate of 1:15.4. Here the northern slope is thus steeper
than the southern. From *Lunkar-la* Pan. 515A and B, Tab. 97, was sketched. Nearly
the whole of *Tarok-tso*, except its eastern part, was to be seen, and its islands in
its northern part. A part of the salt lake of *Tabie-tsaka* could also be seen and
the neck of land with its hills. To the N. 49° E. is *Shakangsham*, beautifully rising
above everything else. From here one gets the impression that the *Shakangsham*
belongs to a range. The snowy Mount *Amlung* to the N. 82° E., is difficult to
place. *Charko-ri*, S. 79° E., is only a few kilometers distant. The mountains called
*Mela-gangri* on Pan. 515B, Tab. 97, visible to the S. 49° W. and S. 88° W., are
certainly parts of the *Surla Range* and the *Bongba-yeke-gangri*. The name *Mela-
gangri* was given us by our guides on the *Lungkar-la*.

On *June 11th*, we covered 14.5 km. S. W. to *Camp CCCCXXVI, Gyänor-
tsangpo*, being at an altitude of 5,187 m. or 162 m. below the previous camp, the
rate of fall thus being 1:89. Pan. 516, Tab. 97, taken from the last camp, shows a
large part of the mighty *Bongba-yeke-gangri Range* with its covering of eternal
snow. To the W. S. W. the *Poru-tso* is situated, though still hidden by the low
hills in the foreground. To the S. 53° E. is Mount *Kapta*, as seen from the same
camp, Pan. 517, Tab. 97.

*Camp CCCCXXVII, Tokya*, was situated 12.7 km. S. W. of the preceding
camp. The first 10 km. took us to the *Chuka-la*, 5,320 m. high, a rise of 133 m.
at a rate of 1:75. From the pass to the camp we had 2.7 km. and a descent of
only 13 m., as the latter had an altitude of 5,307 m.; the rate is, therefore, 1:208.
Pan. 518, Tab. 97, shows, from S. 52° W. to N. 58° W., a mighty range, the one we
have mentioned above. We have here to deal with *one* very considerable and nearly
meridional range, the northern section of which is situated east of *Nganglaring-tso*
and *Shovo-tso*, whilst its middle part is west of *Poru-tso*, and its southern section
to the east of the *Pedang Range*. On my route this range, *Surla*, is crossed in
only one pass, the *Surla-kemi-la*. The orographical importance of the range *Bongba-
yeke-gangri* is, on the other hand, not quite clear. It should certainly not be
