For some reason we found it necessary to eat a considerable amount. The theory of a simple diet, a little fruit, meat once a day and in small quantity, did not work out in practice. After midday the world is a blinding glare and the intake of air seems to burn the lungs. A comparative stillness descends on the scene. On the plain activities cease. Through the double canvas roofing of a tent the sun beats down like a giant with a leaden club. The temperature in the wards increases. At the worst moments you feel distinctly that it would be possible, by giving way to something that escapes definition, to go off your head. A spirit of indifference to everything is necessary. Any kind of worry is simply a mode of suicide. A man, for instance, who feels continually he ought to be up and doing, and that to lie still in vacancy is a sin, does not do well, unless, perhaps, he dwells in a cool stone house, under fans, with plenty of ice, as was the luck of some. There must be no inner conflicts. Cranks soon suffer. Life becomes simplified. An oriental contempt of the West, with all its preoccupations, grows insensibly. When a dripping orderly came to rouse you to see some case, you understood perfectly the attitude of mind that has produced the idea of Kismet. Why move? If the man dies, it is Allah's will. It is Allah's will that he is sick. Let him remain in the hands of Allah. It was during the afternoon and evening that heat-stroke occurred in the main when the humidity of the air began to go up. A great many of the new troops had no idea of the danger of the sun. The Tommy does not estimate a situation very quickly. The attempt to change the main meal of the day to an evening hour did not meet with success, and during the afternoon the men would sit bucking away in their tents, and refuse to adapt themselves to the idea of a siesta. Moreover, the Tommy is obstinate by nature and does not like to give in. He goes on marching in the sun, even though he feels bad, and the collapse is swift and fatal. At about five o'clock, with the temperature falling and the humidity of the air increasing, a period of intense discomfort set in. Perspiration was so profuse that clothes became wringing wet like bathing suits, even if you were sitting still. A kind of air hunger ensued. The few birds in the groves sat with their beaks wide open. It was then that the ambulance wagons began to roll in with their burden of heat-stroke cases, and continued until after sunset. It is a malady which, as I have said, is dramatic and painful to witness....
