A thick mist came on and enveloped us, which considerably added to our trials. Our efforts to get on after we left Kachi at 21,000 feet were desperate, our lungs in convulsion as if about to burst, our pulses hastened, our hearts throbbing (mine being ordinarily very regular) as if they would beat themselves out of our bodies. Exhausted and seized by irresistible drowsiness, the Rongba and I nevertheless at last reached the top. It was a satisfaction to have got there, to have reached such an altitude, although I had long realised the impossibility of getting my men over by this way. It served me also to ascertain the amount of snow on the other side of the range, which, when the fog lifted somewhat, I found to be greater on the northern slope than on the southern. Although almost fainting with fatigue, I registered my observations. The altitude was 22,000 feet, the hour 11 P.M., and there was a strong, cutting North-East wind. I had stupidly forgotten to take my thermometer out of Kachi's pocket when I left him, and was unable to register the temperature, although I had done so only a few minutes before I left Kachi at 21,000 feet. The cold was intense. The stars were extraordinarily brilliant and the moon shone bright for a while over the panorama around me, and though it was a view of utter desolation, it had nevertheless a curious indescribable fascination. Below me, to the south, were mountainous masses buried in snow, and to the South-West and North-East were peaks even higher than the one on which I stood. To the north stretched the immense, dreary Tibetan plateau with undulations and intricate hill ranges, beyond which a high mountain range with snow peaks could just be perceived in the distance. I could see very little snow near by, except on the northern slope of the range I was standing on, and on the hill-tops which dotted the plateau. I had barely taken it in, barely realised the wonder of nature asleep when the mist again rose before me and I saw a gigantic phantom rising out of it. It stood in the centre of a luminous circle, a tall, dark figure in the folds of an enormous veil of mist. The effect was overwhelming, and it was only after some moments that I realised that the spectre wore my features, was a liquid presentation of my own proportions colossally enlarged; that I stood in the centre of a lunar rainbow, and that I was gazing on the reflection of myself in the mist. As I moved my arms, my body, or my head, the ghostlike figure moved, and I felt myself irresistibly changing my postures--oddly and nervously at first--then, with an awakening sense of the ridiculous in my actions--so as to make my image change and do as I did. I felt like a child placed for the first time in front of a mirror.
