weight, picked up this stone and put it on the light load to balance the other, quite unaware of the importance of the stone. This stone was then carried from Gyantse to Shigatse, where a high and important Lama saw it, and recognising that this was a very holy stone, had it kept there. The powerful monastery of Tashilumpo was built over this stone. We passed two small nunneries called Doto and Shidag in snug little valleys to the North of the plain, and on asking why there should be so many nunneries in these parts when in the greater part of Tibet men predominated, I was told that this was due to the fact that it was close to the Nepalese frontier where there had always been much fighting, so that most of the men had been killed and only women had survived. After a short and easy march we came to a small pocket in the hills called Kheru. Here were encamped some people belonging to a nomad tribe who always lived in tents. They were very friendly, put tents at our disposal, and did their best to make us comfortable. They told us that they came here every year in the twelfth month, about January, and left again in the fifth month of the Tibetan year (June) for a place near Tuna, where they disposed of their wool, butter and cheese at the Phari market. There were altogether about twenty families here owning some 200 yaks and 3,000 sheep. Dr. Kellas was slightly better, but Raeburn was not feeling at all well, and Wheeler was suffering from indigestion, so that we were rather a sick party. Kheru lies at a height of 15,700 feet, but it had been very hot all day in the brilliant sunshine, and on the way we had passed lizards and a number of common peacock butterflies. Next morning our march was to Tatsang (Falcon's Nest), a distance of 15 or 16 miles, and over two passes 16,450 and 17,100 feet. The going was easy all the way, as the gradients both up and down the passes were very gentle. Between the two passes was a broad valley, filled with huge flocks of sheep and herds of yaks, and after crossing the second pass, we descended into a great barren and stony plain, more than 10 miles across which was Tatsang and over which the wind blew very keenly. To the South of us appeared the snowy crests of Pawhunri, Kanchenjhow and Chomiomo and the Lhonak peaks. Again I did not keep with the transport, but followed the crests of the hills, where I had lovely views; on the way I saw plenty of gazelle, and was lucky enough to shoot one of them, as they are very good eating. Our camp at Tatsang was pitched just below the nunnery there, which is on the top of a rock and where there are about thirty nuns. Our camp was on a pleasant grassy spot where some excellent springs bubble up out of the ground. These within a few yards formed quite a big stream full of small snow trout. They do not really belong to the trout family, although they have somewhat similar spots, and are very good to eat. Bullock, with his butterfly net, and the
