T. B. Lang, An Historical Summary of the Post Office in Scotland
“ In 1698, Sir Robert Sinclair of Stevenson, had a grant from King William of the whole revenue of the Post Office in Scotland, with a pension of £300 per annum to keep up the Post. The Post Office at this time appears to have been any thing but a profitable concern, as Sir Robert, after due deliberation, gave up the grant, thinking it disadvantageous. ”
