wind much. It runs S. E., and is, therefore, like an accumulator for the snow that is driven by the S. W. wind across the hills. Sometimes it was hard work for us to force our way through these snow-drifts. Just below Camp CCCXXX, the living rock was dark greyish green schistous quartzite. About halfway, it consisted of grey quartz-biotite-diorite (hornblendegranite). Near Cana, CCCXXXI it was grey, phyllitic schist. The latter formed perpendicular walls, about I o m. high, at the sides of the valley, and above them were the screes from the mountains above. The bed of the watercourse in the valley is, therefore, sharply eroded, and has a breadth of from 3o to 5o m. As the bed occupies most of the valley, this is, therefore, rather narrow. Finally the valley opens up a little and in its background to the S. E., a more isolated mountain group is seen. On both sides of it, the country appeared to be rather open. At Camp CCCXXXI, there was some poor grass and the yellow moss which could be used as fuel. A path was seen on a slope, probably worn by wild yaks. Of human beings, we saw no signs. Looking up the valley one would think that no nomads ever use this horrible way and this high pass. Probably there are other, more comfortable passes in the neighbourhood leading from the east to the drainage area of Sliemen-tso.
On February 1 7th, our march continues for 15.9 km. to the E. S. E. and S. E. .ELI
The ground falls 147 m. or to 5,275 m. which is the height at Camp CCCXXX/1;r the rate of slope is thus as I : i o8. The figures show how very slowly the great
and broad protuberance on which we had travelled for such a long time slopes down .f
to regions of the Chang-tang with a more moderate height. It is, of course, very tiring to men and animals to remain for a long lapse of time on heights which
exceed the altitude of Mont Blanc by several hundred meters.,;,
The night temperature went down to —24.1°. The whole day the sky remained Tai
perfectly clear. In the morning the wind was S. E. but soon went over to S. W.
and blew with the violence of nearly a full storm. Heaps of snow had been accu- 68,
mulated in the lower part of the valley, and sometimes it was hard work to force
,
our way through the drifts. The valley was full of sharp-edged gravel and blocks.
Here and there the snow had been swept away from the ice-sheets in the bed. At one place along the left terrace, some mounds of gravel proved that gold-diggers had been at work. Such a place as this has, of course, a name, though as the whole country now was uninhabited, we could not ascertain any geographical names at all. Below this place, we went up on the top of the left terrace and the flat slopes of the left side-hills, gradually leaving the bed at an increasing distance, and finally seeing the last of it where it disappeared to the S. E. In its lower part, it became broader and shallower, and its terraces, lower. It would be impossible to tell in what direction the great open arena across which we now travelled, is sloping, for to the naked eye it seemed to be perfectly level. Judging from the situation of
A LATITUDINAL VALLEY STRETCHING EAST-SOUTH-EAST.
