Wild game is plentiful in the Upper Bhong Valley. I shot numerous hares, some ramchakor and a bar-headed goose during the trip; while Gujjar Singh caught a young, week-old burhel lamb on the summit of the Lungchen Pass, which, however, died after three weeks in captivity. Gazelle are common on the Sutso Plain. By the end of June, Lalbir Singh had finished the inking of his previous surveys, and was ready for fresh work. Accordingly, after spending a couple of days in examining his board, and checking the spelling of his village names with the aid of the local Tibetan officials, I despatched him on a lengthy programme of work in Pharuk and Kharta. It was three months before I saw him again. About this time a messenger arrived from the Dzongpen of Nyenyam, inviting us to visit his district, which lay four marches to the Southwest, in the valley of the Po Chu or Bhotia Kosi R. Although Nyenyam was not one of the districts specifically mentioned in our passport, Wollaston and I decided, with the concurrence of Colonel Bury, to avail ourselves of the opportunity of visiting this little-known area. Leaving Tingri on July 13, with the interpreter Gyalzen Kazi and Surveyor Gujjar Singh, who had now returned after completing his work on the Lungchen Pass, we camped that evening at Langkor, a small village at the Western edge of the Tingri Plain. A cantilever bridge which spans the Gya Chu opposite the village had been carried away by floods shortly before our arrival, and the whole population of the hamlet, male and female, were busily engaged in its reconstruction, working in relays to the accompaniment of prolonged and vigorous blasts on a "conch" which a monk was diligently blowing in order--as it was explained to us--to avert further rainfall until the bridge should be completed. His efforts were rewarded with tolerable success, as the rain held off all day in spite of the threatening storm-clouds which loomed up from the South-west. The most interesting feature of Langkor is an ancient temple, an appanage of the great Drophung monastery of Lhasa. This building, which is said to be over 1,000 years old, contains a sacred stone alleged to have been hurled across the Himalayan Range from India, and to have pitched in the Tingri Plains. The name Tingri is said to be derived from the noise ("ting") made by the falling stone. The stone is carefully preserved inside a wooden box, which is opened with much ceremony on the first day of the Tibetan new year. The temple, which is managed by a committee of fifteen civilian monks (nyakchang), also contains a library of 4,400 books, and an image of the Indian saint Tamba Sanye which is popularly believed to have grown by itself from the ground _in situ_.
