Charter of liberties to the tinners of Cornwall and Devon… (1201)
“ Be it known that we have granted that all tin miners of Cornwall and Devon are free of pleas of the natives as long as they work for the profit of our ferm or for the marks for our new tax; for the stannaries are on our demesne. And they may dig for tin, and for turf for smelting it, at all times freely and peaceably without hindrance from any man, on the moors and in the fiefs of bishops, abbots, and earls, as they have been accustomed to do. ”
