on Pan. 2 54A and B, Tab. 46, is drawn from Chärok. It unrolls only to the south considerable mountains, being probably the eastern continuation of the Kubi-g-angri Range. To the S. 63° E., where the country is very low, the Tsangpo flows down. If Chärok is at 4,657 m., and Camp CLXXXVIII at 4,583 m., and the distance between the two camps 90 km., the difference of height, 74 m., would mean a rate of descent of the river of I: I216. At Camp CCI, S'zapka, 66 km. higher up, the altitude is 4,841 m., or 184 m. higher than at Chärok. Here the rate of descent is thus 1:359. The fall of the river along its long course does not form a regular parabola, but changes from one section to another.
On 7uly 7th, we travelled 8.8 km. north and N. W. to Can CXCVI, Sham-sang, at an altitude of 4,697 m., or 4o m. above the preceding camp, the rate being 1:220. The next day we had 6.7 km. W. N. W. rising only 5 m., or to 4,702 m., which was the altitude at Umboo, Camp CXCVII. The rate was thus only 1:1340. On 7uly yth, we travelled 14.8 km. west to Camp CXC VIII, Tokjonsufg, at an altitude of 4,732 m., or a rise of 3o m., and a rate of i:493.
Pan. 2 5 5A and B, Tab. 46, drawn at the confluence of the Maryum-chu from Maryum-la and the Chema yundung- (or yungdung) River, is of a certain interest. It shows to the S. 6o° W. a distant mountain called Kubri. This cannot be any other than Kubi-gangri, though I have heard the name given as Kubri when I heard of it for the first time, and wrote it down as Kubri. In this form it appears on the panorama. To the N. 5 5° W. is the valley by which the Maryum-chu comes down. To the N. E. and E. N. E. are mountains and ridges obviously belonging to the Pedang Range of Transhimalaya. From a terrace close to Camp CXC VIII, Pan. 257, Tab. 47, was drawn. On this sketch we find the first reliable perspective of the mighty mountains amongst which the source, or sources, of the Bralzmaputra are situated. To the S. 49° W. is a peak that may be the Absi. To the S. 68° W. is a fine view of the Chema yundung-pu, and to the S. 86° W. are other peaks belonging to the Chema yundung. To the north and N. E. is a sea of mountains.
On 7uly ioth, the road is directed to the W. S. W. and S. W. to Shäryak, Camp CXCIX, at an altitude of 4,874 m., or a rise of 142 m., and a rate of i:88.
On 7uly i iM, we approach the Kubi-g-angz-i in a south-westerly direction, marching 6.5 km. to the pass Tso-nili-karg-ang, 5,138 m. high, or 2 64 m. above the last camp, being a rise of 1:24.7. The descent to Camp CC, Hlayak, at 4,861 m., is 5.5 km. in length and 277 m. in height, being a fall of 1:20.
From the pass Tso-niti-kargang I had the first opportunity to make a sketch of all the peaks of the Kubi-gangri, Pan. 2 58A and B, Tab. 47. To the S. 3o° E. and S. I° E. are two peaks, Lung-yung and Karg-am-nakbo, belonging to the same Himalaya Range as the Kubi. To the S. i 6° W. is Ngomo-dingding, then the Absi and its glacier, the Mukchung jungu, Mukchung-tseun, Langla-then, Gaveling,
ALONG THE UPPER TSANGPO TO THE MANASAROVAR.
