AT 1 P.M. we woke up, drenched to the skin, the sun having thawed the thick coating of snow over us. This camp was at 18,000 feet. The wind from the S.E. cut like a knife, and we suffered from it, not only on this occasion, but every day during the whole time we were in Tibet. It begins to blow with great fierceness and regularity at one o'clock in the afternoon, and it is only at about eight in the evening that it sometimes abates and gradually ceases. Frequently, however, the wind, instead of dropping at this time, increases in violence, blowing with terrible vehemence during the whole night. As we were making ready to start again, with limbs cramped and stiff, the sky once more became suddenly covered with heavy grey clouds, and fresh snow fell. There was no possibility of making a fire, so we started hungry and half-frozen, following a course of 70 deg. (b.m.). We waded up to our waists through a freezingly cold stream, and climbing steadily higher and higher for six miles, we at last reached another and loftier plateau to the N.E. of the one where we had camped in the morning. The altitude was 18,960 feet, and we were surprised to find four lakes of considerable size close to one another on this high tableland. The sun, breaking for a moment through the clouds, shone on the snow-covered tops of the surrounding mountains, silvering the water of the lakes, and making a beautiful and spectacular picture, wild and fascinating in effect. Hunger and exhaustion prevented full appreciation of the scene; nothing could stand in the way of quickly finding a suitable place to rest our weak and jaded bodies, under the shelter of the higher hills round the plateau, or in some depression in the ground. I was anxious to push across the plateau, and descend on the N.E. side to some lower altitude where we should more probably find fuel, but my men, half-starved and fagged, could go no farther. Their wet loads were considerably heavier than usual, they panted terribly owing to the great altitude, and no sooner had we come to a partially sheltered spot between the larger lake and its most eastern neighbouring sheet of water, than they all collapsed and were unable to proceed. I was much concerned about them, as they refused to take any cold food, saying it would cause their death. I was really at a loss to see how they could recover sufficient strength for the next day's marching. Eventually, by personally pledging them that they would not die, I persuaded them to eat a little _sato_ and _ghur_. Unfortunately, no sooner had they eaten some of it mixed with cold water, than nearly all were seized with violent pains in their stomachs, from which they suffered for the greater part of the night.
