pass we had 1.6 km. to Camp CCCXCIX, being a fall of 206 m. at a rate of i : 8.
had 4.8 km. up to Sangmo-bertik-la, situated in the Laachung Range at an altitude
On May 7th, we had 6 km. N E. to being a rise of 376 m. at a rate of i : 16.
north to Can CCCC, where the altitude was 5,333 m., or a fall of 157 m. and a rate of i : 53.5. The southern side is thus more than three times as steep as the northern side. In this pass the Lombo Range is crossed; its western continuation is called Kanchung-gangri, like the range north of it. From Camp CCCC Pan. 484A, Tab. 90, is drawn, embracing moderate mountains and no very high peaks.
On May 8th, the road goes 4.4 km. N. N. W. to Damche-la, 5,418 m. high, being a rise of 85 m. at a rate of i :52. On the northern side the distance to Camp CCCCI, Lajcliung, at an altitude of 5,193 m., was 10.7 km. to the N. N. W. and N. N. E., the fall being 225 m. at a rate of i : 47.5. Here the northern slope was somewhat steeper than the southern.
From Camp CCCCI the important panorama, 488A and B, Tab. 91, was drawn, showing two high peaks of Kanchung-gangri to the S. 30° W. and S. 39° W., obviously being the same as those to the N. 37° W. on Pan. 483 , Tab. 90, and to the N. 1° E. on Pan. 2 I OA , Tab. 38. In Vol. III, p. 3o8, there is a watercolour sketch of the same Kanchung-gangri peaks. From the same camp the mountainous regions Luma-nakclien-nakchung, Salung-nakchung- and Salung-nakchen and the valley and pass of Gyandar-ngundor are to the W. S. W., W. N. W. and N. W. In the foreground is Lapchung-tso, the lake from which Chaktak-lsangj5o comes.
On May 9th, we travelled 15.2 km. north, ascending to an altitude of 5,245 m. at Camp CCCCII , Sang-bertik; a rise of 52 m. and a rate of I: 292. From this camp Pan. 485A, B and c, Tab. 90, was taken all around the horizon.' To the N. 61° W. it shows the flat threshold of Dicha-la, obviously situated in the latitudinal valley between the Lapchung and the Kanchung Ranges. To the N. N. E. is Sangmobertik-la with the continental water-parting. To the S. 62° E. the Nakbo-gongronggangri with its snowy peaks is visible, being a part of or a ramification from the Kanchung-gangri. To the S. i 3° E. the Chomo-uchong group is still visible in an opening between nearer hills. A part of the Kanchung-gangri Range is now visible from the northern side to the S. S. E., S. W. and west. To the S. 14° W. we see the same peak as the one to the S. 3o° W. on Pan. 488A, Tab. 91.
On May 'Ilk, we travelled 12.2 km. N. N. E. to Camft CCCCIII, Sangmobertik, where the altitude is 5,586 m. The rise is 341 m. and the rate 1:35.8.
