To account for these and other hairbreadth escapes, popular superstition freely alleged that Yawkins insured his celebrated lugger by compounding with the Devil for one-tenth of his crew every voyage. How they arranged the separation of the stock and tithes is left to our conjecture. The lugger was perhaps called the _Black Prince_ in honour of the formidable insurer. Her owner’s favourite landing-places were at the entrance of the Dee and the Cree, near the old castle of Rueberry, about six miles below Kirkcudbright. There is a cave of large dimensions in the vicinity of Rueberry, which, from its being frequently used by Yawkins and his supposed connection with the smugglers on the shore, is now called “Dirk Hatteraick’s Cave.” Strangers who visit this place, the scenery of which is highly romantic, are also shown, under the name of the “Gauger’s Leap,” a tremendous precipice. “In those halcyon days of the free trade,” says Scott, “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.” This condition of affairs prevailed until peace had come, after the final defeat of Napoleon at Waterloo. The Government then, as always, sadly in need of new sources of revenue, was impressed with the idea that a fine sum might annually be obtained by placing these shy Highland distillers under contribution. But there were great difficulties in the way. The existing laws were a mere dead letter in those regions, and it was scarce likely that any new measures, unless backed up by a display of military force, would secure obedience. The Duke of Gordon, at that period a personage of exceptionally commanding influence with the clansmen, was appealed to by the Government to use his authority for the purpose of discouraging these practices; but he declared, from his place in the House of Lords, that the Highlanders were hereditary distillers of whisky: it had from time immemorial been their drink, and they would, in spite of every discouragement, continue to make it and to consume it. They would sell it, too, he said, when given the opportunity of doing so by the extravagantly high duty on spirits. The only way out of the difficulty with which the Government was confronted was, he pointed out, the passing of an Act permitting the distilling of whisky on reasonable terms. The result of this straightforward speech was the passing of an Act in 1823 which placed the moderate excise duty of 2_s._ 3_d._ a gallon on the production of spirits, with a £10 annual license for every still of a capacity of forty gallons: smaller stills being altogether illegal.
