coolies with their hands, managed to catch quite a number of fish, and we had them for dinner that night. The ground round our tents was full of holes out of which the marmot rats kept appearing. They were very tame, and did not seem to be in the least afraid of us. Dr. Kellas had had a very trying day. He had been rather better, and had started riding a yak, but he found this too exhausting and coolies had to be sent back from Tatsang to bring him on in a litter, so that he did not arrive at Tatsang till late in the evening. Tatsang is 16,000 feet, so the night was cold, the thermometer inside the tent registering 7 deg. of frost, though it was June 4; outside there must have been quite 15 deg. as the running streams were all frozen over, but once the sun had risen everything warmed up and we had a beautiful warm day. Dr. Kellas started off in his litter at 7 a.m. in quite good spirits. I did not start till an hour later, as I had wanted to see everything off, and then went up to visit the nunnery, over which the lady abbess showed me. There were thirty nuns living there, all with shorn heads and wearing a curious wool head-dress. The place where they worshipped was full of prayer wheels, both large and small. They sat down behind these, and each nun turned one or two of them if they could manage it. The room was very dark, with a low ceiling, and at the end were several statues of Buddha covered over with gauze veils. In another room there was a large prayer wheel which they said contained half a million prayers. After leaving the nunnery we jogged along a dry and barren valley which gradually rose in about 12 miles to a pass 17,200 feet. On the way we passed Dr. Kellas in his litter, who then seemed to me to be still quite cheerful. I then rode on and at the top of the pass saw three ovis ammon, and after a chase of about a mile I shot one, which afforded plenty of food for the coolies for some days. It was a full grown ram about five years old and we had great trouble in getting the carcass on to a mule, as it was enormous and very heavy. After this I rode on down the valley for another 10 miles to Khamba Dzong. There were actually a few bushes in this valley, which was carpeted with the pretty pink trumpet-shaped flower mentioned above, also with light and dark blue iris. Suddenly the valley narrowed into a fine limestone gorge, and all at once the fort of Khamba Dzong appeared towering above us on the cliffs. It was really a very impressive sight and some of the architecture of the round towers was very fine. I found that Morshead had been waiting here for about nine days, but had employed his time in fixing the old triangulation points. Soon after I arrived the Jongpen came down to pay us a visit. He was quite a young fellow, only about twenty-four, but very pleasant and polite.
