character, beginning from N. 60° W. and in the course of half an hour turning
over north and N. E. to E. N. E., after which it diminished in force.

On October 7th we proceeded 12.3 km. between N. E. and E. N. E. to
Camp XXXIII, where the height is 4,923 m. or 46 m. above the previous camp,
meaning a gentle rise of the ground, as 1:267. We are still following the enormous
latitudinal valley to the E. N. E. and the landscape remains extremely monotonous.
From Camp XXXII the Deasy Group was visible to the S. 44° W., and the prin-
cipal peaks of the snowy Kwen-lun Range to the S. 88° W., N. 63° W., N. 31° W. —
between these two there may well be a latitudinal valley — and N. 13° W.

Starting from Camp XXXII, we leave the main brook behind to our left,
where it makes a bend to the north and N. E., and empties into the salt marshes
of the western shore of the next lake. The lake is, however, not yet in sight.
It is hidden by a ridge of low hills situated on its southern shore. Following the
southern base of these hills, we cross a series of small erosion furrows all bound for
a very long and narrow depression, the bottom of which is covered with a sheet of
perfectly level yellow clay that has been brought down in the form of silt by the
temporary watercourses around. Slowy ascending the hills, we get a beautiful view
of the whole lake. Continuing on the top of the hills we find a spring of fresh
water. At Camp XXXIII the grass is as good as before. This part of Tibet had
indeed proved to be much more favourable than I had suspected. The only diffi-
culties are the continual hard winds, and the early cold, which last night had been
down to —24.8°.

From a point 2.5 km. S. 69° W. from Camp XXXIII, Pan. 46, Tab. 8, was
made of the horizon from S. W. over north to N. E., the other half being hidden
by near, undulating, low hills. To the S. 45° W. the highest point of the Deasy
Group is still visible in a very fine, distant perspective. From S. 84° W. to N. 50° W.
we have a brilliant view of the snowy Kwen-lun Range which now for so many
days had been in sight, and soon would disappear altogether. We had never
before had such a continuous view over the whole dark range with its white snow-
fields and small glaciers. To the north and N. E. no high mountains or peaks could
be seen. From the plain S. W. of the lake a long narrow neck of land goes out
dividing this part of the lake into two bays. To a great extent, nearest the shore,
the plain is white clay dust and salt, which is whirled up in clouds by the strong
N. W. wind. A good deal of the S. W. part of the lake was now frozen over, but
the ice was still so thin that it became broken up by the wind and drifted over
the lake. The water is salt though not of a very high percentage. On the northern
shore, there are low barren hills; on the southern, our ridge of hills falls rather
directly into the shore, though here also are some patches or stripes of flat land with
a few points of white silt or clay. We were about 60 m. above the lake, the absolute
