Hedge laying was always charged from the "chain" length in those days and i remember his father carried it around in the boot of his car.I mentioned this to my friend and to my surprise he still has it!.It must be over 80 years old and measures 22 yards.

On old forms of measurement. I had a jotter at school that had various tables on the back.One mentioned rod,pole and perch which were terms of length measure these must go way back.Does any one else know of these terms.
