was said to be a deadly poison to horses; numbers of Alpine 
Choughs (P. @lpinus) and higher up flocks of Red-billed Choughs 
(F. graculus) were seen, and perched on a rock not far from 
the Pass, a solitary Lammergeyer (G. barbatus.) 
The pass 1 found to be a narrow ridge; with a glacier sloping 
down its north side, across which a narrow path had been 
roughened for our descent. I remained at the top for about 
an hour; read the mercurial barometer, took the temperature 
of the air and the boiling point of water (180°°8 F.) and vic- 
timised.as many of our followers as possible to find out the 
state of their pulse, respiration, and bodily temperature. At 
the end of that time I began to experience a decided feeling of 
nausea which reminded me at once of what I had felt about a 
week ago at an elevation of about 19,000 feet; so I decided to 
get to a lower level as quickly as possible. I walked over 
the glacier and mounting my Yak soon descended, over very 
rough stony ground, to a small lake near which our breakfast 
was prepared. Although I had no headache whatever, I could 
only manage a cup of tea; so discarding the Yak I mounted 
my horse and following the valley along the course of a small 
stream running from the Kardong glacier, rode on for about 
twelve miles to the village of Kardong here. On my way I 
noticed numbers of Redstarts (R. erythrogastra and R. rufiven- 
tris) near the stream, and a large flock of Pigeons, all Columba 
rupicola apparently. 
The little Tibetan village of Kardong looks very picturesque ; 
itis situated at the mouth of a side valley and has numerous 
Chortens * dotted about it as usual. I reached camp after 
six o’clock in the evening and found that many of our 
followers were suffering from the effects of the elevation of 
the march, but as we are now camping at a little less than 
13,000 feet they will soon get over their troubles. 
3rd.—A short march to-day from Kardong to the village of 
T'satti, where we are encamped ; elevation 10,589 feet. From 
Kardong the valley bends to the right and becomes a narrow 
gorge, exhibiting in places a high bed of conglomerate which 
has been deeply cut through by the small Kardong stream. The 
gorge debouches into the valley of the Shayok, nearly at right 
angles to the latter, and the small stream from the Kardong gla- 
cier there enters the Shayok River which at that point runs from 
south-east to north-west. The birds noticed near Kardong 
were flocks of Choughs, a few Ravens and Hoopoes, and a good 
number of Montifringilla hematopygia; in the steep descent 
through the gorge among the willow and tamarisk jungle were 
numerous Tree Warblers (Phylloscopus viridanus and P. tristis)
