Wednesday 23rd June, light breeze, clear and very warm. In the evening, having set aside my various struggles, I sit out on the patio re-reading "Life" so I'll know what I said about the "disappearence of the Y chromosome", should anyone ask me at the Seeing Further Cafe Scientifique next week. Balmy air. Swifts hawking and shrieking in the clear sky, those Nordic tiger moths, who seem to have settled down and colonised the gardens, batting about up in the treetops, a big white three quarter moon on the rise. It's midsummer, soon be July and time to pack up and go away. The squirrels have taken all our strawberries, it's nearly the end of another working year.
