Well, BD, you encouraged me to look up more shearing terms on Wiki and I found one which surprised me (although it might be well known to others). And that was ‘bellwether’. As I listened to Anthony Green each election night, I fancied the ‘bellweather’ (sic) seat was the one which gave an idea of which way the electoral wind was blowing. That is largely because I had never seen it written, so was ignorant of the spelling. It also made some sense. But not so. A ‘bellwether’ is a wether considered to be a good leader of the flock, and thus a bell is placed around his neck so the shepherd can hear where the flock is. (By the way, it is snowing on my comments.)
