Hi 



Remarks. 



Road for 7\ miles along the left 

 hank of the Indus, the latter part very 

 rough and stony. The river in some 

 places is not more than from 30 to 40 

 feet in width ; after passing the village 

 of Mahe (on the opposite hank) the 

 road turns to the westward up the 

 Rulang-chu, a small clear stream over- 

 shadowed with tall tamarisk trees. 



Road for 2\ miles the same as yes- 

 terday, through tamarisk trees up the 

 Rulang-chu. It then crossed the 

 stream, and proceeds over undulating 

 stony ground to Puga, the site of the 

 borax and sulphur mines. The borax 

 is collected from the surface of the 

 ground on both banks of the rivulet. 

 The sulphur is dug out of the side of 

 the hill on the northern bank. The 

 bed of the stream is full of hot springs 

 varying in temperature from 80° to 

 148° the boiling point of water being 

 only 186°. The stream is full of fish. 

 Its temperature is considerably higher 

 than that of the air. k.t 8 a. m. when 

 the air was only 32° ; the water was 

 62°. This may account for the size of 

 the tamarisk trees on its banks, many 

 of which are 15 and 16 feet in height. 



Halted to observe the meteorological 

 and magnetical instruments ; and to 

 examine the sulphur and borax mines. 

 Thermr. at 5 a. m. only 13°. 



Road up the Rulaug-chu, extremely 

 stony. 



Road an easy ascent for 3^ miles to 

 the top of the Pulakonka Pass, where 

 I connected this year's survey with that 

 of last year. Then an easy descent for 

 12| miles to the northern bank of the 

 salt Lake, called Chokhar by the La- 

 hulis, and Thogji Chenms by the Tibe- 

 tans.
