The next day or two was spent mostly in reading letters and newspapers. Our postal arrangements were at first rather complicated, there being no regular postal service to the provinces in Tibet. We had, therefore, to make an arrangement with each Jongpen to forward on our mail. Phari was the last post office, and the postmaster there had to arrange with the Phari Jongpen for a messenger every week to go with our posts to Khamba Dzong; we had left money with him for the purpose of paying the postman. At Khamba Dzong we had arranged with the Jongpen there that he should forward our letters to Tinki, and at Tinki we had made further arrangements for them to be sent on to Shekar Dzong and from Shekar Dzong they were to be sent to Tingri. We had left money for this purpose with the various Jongpens, and each Jongpen as he received the mail bag was to affix his seal on it and send it on as quickly as he could to the next Jongpen. This system worked very well for the first two months, but after we had moved to Kharta, partly owing to floods, and partly perhaps to the laziness of the Shekar Jongpen, our mails were all held up and we eventually had to send coolies back from our camp to Phari to bring them along. The best plan another time would be to take with the Expedition a certain number of coolies to be used purely for going backwards and forwards with the mails. On July 13 Morshead and Wollaston left to go to Nyenyam in response to a cordial invitation from the Jongpen, asking that some of the Expedition should visit the place. We were glad to accept, and this should be a very interesting part of the country botanically. CHAPTER VI THE MOVE TO KHARTA I had arrived back at Tingri on July 11, and remained there in the Chinese rest-house until July 24, when I started to move the base camp and all the stores round to Kharta. During the time I was not left always alone, for Heron came in occasionally for a night between his various geological expeditions to the North. Wheeler also came down for a change and a rest, and to develop the photographs that he had taken. He had been having a very trying and provoking time in the high camps, as the weather had been bad, with frequent snowfalls. Nearly every day he climbed up to a spur 20,000 feet or more in height, yet in spite of waiting all day there in the icy cold winds or driving snow, it was but seldom that he was able to get a photograph, and then the clouds would only lift for a few minutes.
