There was always plenty to do at Tingri, so the time passed quickly. Much photographic work had to be done and much developing and printing of the many photographs that were being sent in by the various members of the party. Supplies had also to be sent out and arrangements made for the comforts of the climbing party in the Rongbuk Valley. There were also several expeditions to be made round Tingri, and these were full of interest. Anemometers were very popular in this district; they were fixed by the Tibetans above small prayer wheels, and owing to the constant winds, it was seldom that the prayer wheels were not revolving. Many yaks' horns, carved all over with prayers, were lying about on the different Chortens or Mani walls. The barley, which was only just coming up when we arrived, was now 18 inches high and coming into ear, and though we were over 14,000 feet, the crops looked very healthy and even. Every evening during this period we had heavy storms of rain with much lightning and thunder, and fresh snow used to fall during the night as low as 15,000 feet, but most of it melted again during the day. During this period the plains round Tingri were rapidly becoming marshes and the rivers quite unfordable. The storms always gathered to the North of us, along the Sipri limestone ridge, and the high mountain chain that formed the watershed between the Brahmaputra and the Bhong-chu. These storms generally worked down towards the South. Occasionally fine days came to us when there was a strong South wind to blow the rain back, and it was seldom that the Monsoon clouds brought rain directly to us from the South. The Sipri range was a very conspicuous limestone range to the North of us, the limestone being worn into the most curious shapes. It was looked upon by the Tibetans as being a holy mountain, and on its slopes were many small monasteries. Hermits also took up their abode in the limestone caves below the summit. Pilgrims used to come from great distances to make the circuit of the mountain. This took generally five days, and much merit was acquired by doing so.
