187 Eckenstein and Knowles came up on the eleventh. Another fine day. I was still very ill; my temperature 39.4° Centigrade. I did not at all realize the cause at first, simple as it was. The true explanation was very far-fetched in the actual sense of the word. My symptoms became unmistakable before long and I had to admit that I was suffering from malaria. The hardships of the journey had removed my physiological protection and the bug stated to buzz about. I was thus the proud possessor of another world's record; the only man who had had malaria at over twenty thousand feet! Incidentally, I was also the only poet at that altitude. I have always been very amused at Shelley's boast that he had "trodden the glaciers of the Alps" --- the Mer de Glace and the Glacier des Boissons! But I was actually writing poetry in these camps. Better poetry. Like the man who committed suicide when he learnt that the was unable to move his upper jaw, I had been annoyed by reading somewhere that it was impossible to find a rime to "silver". I spent my spare time in thinking up all the most impossible words in the language, finding rimes for them --- good rimes, not mere assonances --- and introducing them into "Ascension Day" and "Pentecost". In that poem will therefore be found rimes for refuge, reverence, country, virgin, courtesan, Euripides, Aristophanes, Aeschylus, Aischulos, Sophocles, ARistobulos, Alcibiades, fortress, unfashionable, sandwich, perorate, silver, bishop (eight rimes for this word), Sidney (three rimes for this), maniac, Leviticus, Cornelius, Abra-Melin, Brahmacharya, Kismet, Winchester, Christ Church, worship, Chesterton, Srotápatti (two rimes to this), Balliol, and so on. I have mentioned hardships. It may be interesting to mention the nature of these. The first and greatest was malaise, which was mostly due to lack of food and exercise. The latter complaint seems rather ridiculous; but it is an absolute fact. One must not bring damp things into the tent; if one does, it practically destroys the efficacy of one's protection against cold. One must therefore stay cooped up in one's tent as long as the weather is bad. I was in charge of the kitchen and had to go out in all sorts of weather; but that was hardly exercise. I often found that by the time I had filled and lighted the stoves and got the snow melted, I could not stand the cold any longer. I had to rush back to my sleeping-bag and warm up while someone else prepared the food. {318} We kept warm with kangri, of a sort, when things got too bad. We had brought up a number of Japanese instras, but they would not burn; there was not enough oxygen. The cartridges could however be used if left loose in empty biscuit tins. For a similar reason pipe-smoking was impossible; the only way to do it was to relight the pipe from the flame of the candle at each puff. We had a few cigars and we could smoke these quite comfortably. (It appears that the altitude is not wholly responsible for this. At greater heights on Kangchenjunga I smoked my pipe as comfortably as at sealevel.) This same is true about food. We found it difficult to eat anything but what may be called delicacies from the standpoint of people in our position. I felt a certain distaste for food. I had to be "tempted" like an invalid or a fastidious child. It became obvious that Eckenstein's German army theories were inapplicable to Himalayan exploration. We suffered little from cold in the acute way, but rather from a chronic effect. The problem of cold has not been scientifically stated by any explorer so far as I know. It is thus: The normal temperature of the body is 37° centigrade. If therefore the temperature of the air is 30° one has to make up the difference by the heat disengaged by the combustion of food. If the temperature is 23° one requires theoretically twice as much food, if 15° three times as much, if 8° our times as much, if 1° five times as much, if -6° six times as much, if -13° seven times as much, if -30° eight times as much. There temperatures are very much less hot and less cold than those actually experienced. The maximum and minimum thermometers proved altogether unreliable; and the observations on the chart refer to more or less arbitrary times. Other thermometers showed temperatures of over 40° and under 30° centigrade. Unfortunately, simple arithmetic is not the only consideration. The digestive apparatus is calculated for dealing with an amount of food corresponding to, I don't know what temperature, but we might say at a guess 1°. If the average temperature is less than this, it means that you have to eat more than you can digest; and that means a gradual accumulation of troubles.
