I was in this camp for five days; most of them spent huddled under rocks waiting for the clouds to lift. I had one beautiful day, my only one in six weeks, and got some very nice photographs of Mount Everest and its West ridge. It is surprising how a little good weather and the feeling of having really done some work affects one's spirits! On August 21 I moved back to my base camp at the glacier snout, again trying for a station at the corner--and failing. I had not done nearly as much as I wanted to do; but there seemed to be no end to the bad weather, and only a month or a bit more remained in which to map the whole of the East side of the mountain: and I had heard from Colonel Bury that there would be a considerable amount of work on that side. Originally, I had hoped not only to return to the bridge over the R[=a] Chu to complete the work in the Kyetr[=a]k Valley, but also to take several stations in the valleys running North from the 23,000-foot group North of Everest. But again apart from shortage of time, the weather made it out of the question, and I went through to Kh[=a]rta, via the Doya La, arriving there on August 27. The change in scenery immediately one crosses the Doya La is most marked, both as regards rock and vegetation. The former--mostly gneiss--is far more rugged and interesting, and there is infinitely more of the latter. The Headquarters camp at Kh[=a]rta, in a little poplar grove, was pleasant indeed after the bleak, uninteresting Rongbuk Valley; and I thoroughly enjoyed my five days there, developing and printing; busy days, but very different from lying on one's back on the sharp boulders of the Rongbuk moraines. Mallory, Bullock and Morshead were in Kh[=a]rta when I arrived; Colonel Bury and Wollaston returned from their excursion to the Popti La soon after, and Raeburn arrived on September 1. It was a great treat to me to be able to "swap lies" with so many people, after two months almost wholly alone! On September 3 Morshead and I started up the Kh[=a]rta Chu in the wake of Mallory and Bullock, who had gone up to get the "bundobust" for the final fling going. As usual, bad weather dogged my footsteps, and although the weather while I was in Kh[=a]rta had been glorious, Morshead and I spent seven days in taking two very indifferent stations in the lower part of the Kh[=a]rta Valley, before joining the remainder of the expedition at the "Advanced Base" on September 11. A further eight days were spent there, waiting for the weather; but in that time I was able to get two very useful stations, one on either side of the valley.
