Oct. 1849. YEUMTSO LAKE. L63 



on the previous day, about 600 or 800 feet above 

 Yeumtso, and 17,500 feet above the sea : it is a mile and a 

 half long, and occupies a large depression between two 

 rounded spurs, being fed by glaciers from Kinchinjhow. 

 The rocks of these spurs were all of red quartz and slates, 

 cut into broad terraces, covered with a thick glacial talus 

 of gneiss and granite in angular pebbles, and evidently 

 spread over the surface when the glacier, now occupying 

 the upper end of the lake, extended over the valley. 



The ice on the cliffs and summit of Kinchinjhow was much 

 greener and clearer than that on the south face (opposite 

 Palung) ; and rows of immense icicles hung from the cliffs. 

 A conferva grew in the waters of the lake, and short, hard 

 tufts of sedge on the banks, but no other plants were to be 

 seen. Brahminee geese, teal, and widgeon, were swimming 

 in the waters, and a beetle (Mapkrus) was coursing over 

 the w T et banks ; finches and other small birds were 

 numerous, eating the sedge-seeds, and picking up the 

 insects. No view was obtained to the north, owing to the 

 height of the mountains on the north flank of the Lachen. 



At noon the temperature rose to 52° 5, and the black- 

 bulb to 104° 5 ; whilst the north-west dusty wind was so 

 dry, that the dew-point fell to 24° 2.
