Remarks. 



Road round the northern end of the 

 Lake, and thence through a gap by 

 which the lake formerly had an exit, 

 as is proved by the millions of shells 

 still existing in the ancient lacustrine 

 formations, at a level of at least 150 

 feet above that of the present lake. 

 From this gap the road ascended the 

 plain of Kyung to the foot of the 

 Tunglung Pass. 



Snow fell during the night, and we 

 found the ascent of the Tunglung Pass, 

 about 1500 feet, extremely fatiguing. 

 The cold was intense, and the wind 

 high ; and the snow and sleet were 

 very annoying. The descent was rough, 

 steep and slippery for about 3 miles. 

 Thence for the rest the road was down 

 a gentle descent along the left bank of 

 the Giah rivulet, passing at 13 miles 

 the village of Rumchi. 



We found it absolutely necessary to 

 halt after the last three long marches 

 which had prevented us from taking 

 any observations. 



Road good and broad along the left 

 bank of the Giah rivulet. Rocks 

 throughout this day's march of a hard 

 compact greenish sandstone, alterna- 

 ting with a silicious greenish conglo- 

 merate, and standing in almost per- 

 pendicular dykes. The conglomerates, 

 although extremely hard, are generally- 

 worn smooth. If they could be cut 

 and polished they would form beauti- 

 fully variegated slabs. 



Road good down the Giah rivulet 

 which was crossed four times by good 

 bridges of poplar spars. Ukshi stands 

 at the junction of the Giah rivulet with 

 the Singhi-chu, or Indus. 



Road along the left
