The Limits of a Market
" For the benefit of those who are not cognoscenti in such matters,
let me explain that in the middle ages 20 miles was
considered to be the distance
covered by a journeyman in a day. The day was divided into three parts -
six and two thirds miles to travel to the market, one
third of the day -
equivalent to another six and two thirds - at the market ,
and another six and two thirds back that is the reason for the restrictions "
