I did not feel the power of the Great Heat until yesterday since the hottest period began. Yesterday morning I was still working unaffected in the sun. But in the afternoon even in our flat with all the windows opened I couldn't fall asleep as before. I was naked to the waist but I perspired all the same. I took up a fan for the first time to cool me off. It proved futile in the stuffy room. There wasn't a breath of air. I could hardly lie on the bed for a rest. Then I went to the bathroom washing myself to relieve my restlessness. We were so agitated by the heat wave that I slept very badly last night.
