Rod, Pole or Perch?
Nope. Never heard of 'Dyno-Pole' or 'Dyno-Perch' Snoops. Who are they?
Wasn't a response to your Dyno query .... merely pondering if the rods referred to were in anyway connected to the Rod, Pole or Perch as taught when I went to school.
I still remember the day in my second year of primary school... Not sure how old that made me...
Our teacher was Mr. Wise - a violent thug of a man who commanded (and got) respect... He would throw the board rubber at you for the most minor offence and I remember him beating my mate Stephen Burke senseless for some minor indiscretion...
Anyhooo...
One day we trooped into class and he was writing on the blackboard... writing out all the imperial measurements..... 1 chain = 22 yards, 1 gill = whatever that equalled, etc...
We all sat down and watched him in silence, nobody said a word (we wouldn't dare)...
After a while, somebody realised that we were eventually going to have to copy this lot down so she (dirty swat) got her book out and started scribbling....
Of course, once one started another set off and then another until we were all furiously copying this stuff down from the board and Mr. Wise was still writing it...
I can still see the bastard to this day, he was holding a red text book in his left hand, writing in chalk with his right and studiously ignoring us all... all in complete silence apart from the occasional screech of chalk on the blackboard (can you say that now?) and us all furiously scribbling and trying to catch up...
Eventually, he got to the last of the three blackboards, closed his book and turned to look at us... We were all still scribbling...
Then he said
"you don't have to learn any of that any more" and rubbed the whole lot off! Fucking bastard!
I assume it was some personal protest against the metric system...
