over 16,000 feet, we suffered more or less from mountain sickness. Some 
people seem to be under the impression that mountain sickness is more or 
less of a myth, but after a long experience of it at elevations varying from 
16,000 to 19,000 feet, I sincerely wish that I could indorse that impression, 
I know of no more miserable or enervating sensation than the awful headache, 
giddiness and nausea, which are its characteristicsymptoms. It commences 
to affect me at about 16,000 feet, and though it does not absolutely dis- 
appear, still one does get in some degree seasoned to it, and after a time 
can even sleep, with comfort. Of course any violent exercise, such as 
running, will bring it on at once and then the only cure is to sit down and rest, 
Averaging about 14 miles per diem we still kept moving east, the country 
being of a sandy undulating nature with a sprinkling of salt lakes. These 
lakes are fed by snow water from arange of hills lying to the north, and 
must at some time have been much more extensive than at present, because 
for miles back from the present high-water mark there are a series of water- 
washed ridges, which ‘undoubtedly were formed by the lapping of waves, 
The elevation at one time reached 18,400 feet, and there the Antelope be- 
came scarce and far harder to stalk, We saw occasional marks of Yak, 
and as we had now come over 100 miles east of the Thibetan frontier 
without shooting one, we began to feel anxious about our prospect of sport. 
On August 19th with our camp on the shore of Horpu Cho,a fine fresh- 
water lake at about 17,300 feet, Gerry and I started off in a piercing wind 
with occasional hail showers, to spy the adjoining nullahs, I found a solitary 
bull, and after an easy stalk got my first shot at about 150 yards, and 
promptly missed, but was lucky enough to knock him over stone dead with 
the second barrel. Iwas disappointed at finding him to be a smail beast ; 
but never having been close to one before, I had utterly misjudged his size, 
We hada lovely view of the lake from one of the hills, It must be quite 
60 miles round, and is studded with islands around which there were 
quantities of geese and duck, evidently breeding, while the whole of the 
southern shore was clothed ina luxuriant crop of grass, which was a great 
treat for our poor half-starved ponies, We had a high pass to-negotiate 
next day, 18,500 feet, before coming on to a place where a friend of mine 
had shot two Yak the year before. 
This was August 2lst,and was the red-letter day of our expedition, and 
very nearly ended in disaster. Gerry and I started very early, leaving the 
caravan to follow us, ard after going about seven miles saw two Yak graz- 
ing a long way off. It was hailing and bitterly cold ; but we managed to 
stalk up to about 200 yards of the bulls, when, having won the toss for first 
shot, I let drive with my ‘303, and broke my beast’s foreleg, hitting him again 
in the body with the left barrel, Off he went like a flask of lightning, so I
