338 MY FIRST JOURNEY ACROSS THE TRANSHIMALAYA.

by the meridional valley of the Mü-chu. The mountainous country to the E. N. E.

of the Dangbä-la is, however, too little known — i. e. not known at all — to permit

us, with any degree of certainty, to regard the Dangbä-la Range as the immediate

continuation of the high range on the southern shore of the Nam - tso. With our

present state of knowledge this seems anyhow to be the case.

On February 4th, we crossed a new pass, Ta-la, 5,436 m. high, being at

527 m. above Camp CXXII, from where the distance is i o km. in an E. S. E.

direction and the slope as I : 18.9. From the pass we had 11.8 km. S. E. to Camp

descent being as 1: 12.9. Here again the southern slope is very steep. It is difficult

to determine the orographical dignity of the range of Ta-la. Either it is a rami-

fication from the Nien-chen-tang-la, or it is a special range situated south of it.

Panorama 140, Tab. 2 5, is taken from a point not far below Ta-la, and S. E.

of the pass. In my personal narrative' is a reproduction of a panoramic sketch

drawn from the pass itself where the nearest protuberances of the crest on both

sides of the saddle only permit a view between S. 41° E. and S. 18° E. Some of

the near and distant peaks are easy to identify as appearing on the two panoramas.

The view from Ta-la unrolls three or four different ranges in front of us, or rather

ramifications from one and the same range. To the S. S. E. we behold some of the

distant, snow-covered peaks belonging to the northern-most range of the Hima-

laya. In front or north of them is the mighty valley of the Tsangpo or Upper

Brahmaputra.

Pan. 142A and B, Tab. 2 5, gives us a view of the landscape around Camp CXXIII,

Hor, with the mountain regions of Peeri to the S. W., Ayang to the W. S. W., the

Gula valley to the west, the road to Ta-la to the N. N. W., the Yamdo valley to

the N. N. E. and the Kori-yuri Mountain to the N. E.

On February 5th, our road goes 7.2 km. south in the Pema valley to Camp

The rate of descent is here as 1:40.2.

The march of February 6M shows the morphological law in a more pro-

nounced way than before. We had 7 km. S. S. E. to the pass La-rok at an altitude

of 4,44o m., only 96 m. higher than Camp CXXI V, the rate being as 1:73. From

the pass to Camp CXXV, 3,949 m. high, the distance is 8.6 km. S. E., or a descent

of 491 m. at a rate of 1:17.5. La-rok certainly is situated in a quite secondary range,

being a ramification from the nearest principal range to the north.

Pan. 145, Tab. 26, is a view from La-rok to the east, S. E. and S. S. E. The

most interesting feature on it is that a group of rather accentuated peaks are situated
