Walter Scott,
Rob Roy
(1818)
“ Beneath these fords, there was no pass of general resort until so far east as the bridge of Stirling; so that the river of Forth forms a defensible line between the Highlands and Lowlands of Scotland, from its source nearly to the Firth, or inlet of the ocean, in which it terminates. The subsequent events which we witnessed led me to recall with attention what the shrewdness of Bailie Jarvie suggested in his proverbial expression, that "Forth bridles the wild Highlandman." ”
