The eccentric engineer

I´M TOLD we´re expecting a hot, dry summer in the UK. But then I¿ve been told that before. However, on the off-chance that the skies remain blue and the sun beats down, I have been giving some thought to what to do about my vegetables. Being on a water meter, I´m loathe to spend the summer watering them with a hose, but I couldn¿t bear to see them shrivel and die. So I got to thinking about a bore hole and mediaeval robot musicians ¿ not something that will come as a surprise, I´m sure.
