Many corresponding circumstances are detected by readers of which the Author did not suspect the existence.

He must, however, regard it as a great compliment that, in detailing incidents purely imaginary, he has been so fortunate in approximating reality as to remind his readers of actual occurrences.

It is therefore with pleasure he notices some pieces of local history and tradition which have been supposed to coincide with the fictitious persons, incidents, and scenery of Guy Mannering.
The prototype of Dirk Hatteraick is considered as having been a Dutch skipper called Yawkins.

This man was well known on the coast of Galloway and Dumfriesshire, as sole proprietor and master of a buckkar, or smuggling lugger, called the 'Black Prince.' Being distinguished by his nautical skill and intrepidity, his vessel was frequently freighted, and his own services employed, by French, Dutch, Manx, and Scottish smuggling companies.
A person well known by the name of Buckkar-tea, from having been a noted smuggler of that article, and also by that of Bogle Bush, the place of his residence, assured my kind informant Mr.Train, that he had frequently seen upwards of two hundred Lingtow men assemble at one time, and go off into the interior of the country, fully laden with contraband goods.
In those halcyon days of the free trade, the fixed price for carrying a box of tea or bale of tobacco from the coast of Galloway to Edinburgh was fifteen shillings, and a man with two horses carried four such packages.
The trade was entirely destroyed by Mr.Pitt's celebrated commutation law, which, by reducing the duties upon excisable articles, enabled the lawful dealer to compete with the smuggler.

The statute was called in Galloway and Dumfries-shire, by those who had thriven upon the contraband trade, 'the burning and starving act.' Sure of such active assistance on shore, Yawkins demeaned himself so boldly that his mere name was a terror to the officers of the revenue.
