Sir Walter Scott, notable historical novelist of the 19th century describing what were the requirements of a local tourist guide :
‘You explained to your postilion the length of your tour and the objects you were desirous it should embrace and you found him perfectly competent to fix the places of rest or refreshment with due attention that those should be chosen with reference to your convenience and to any points of interest which you may desire to visit’ ‘Walter Scott, ‘Chronicles of the Canongate’.
