The origin of Old Mortality, perhaps the best of Scott's historical romances, is well known. In May, 1816, Mr. Joseph Train, the gauger from Galloway, breakfasted with Scott in Castle Street. He brought gifts in his hand, - a relic of Rob Roy, and a parcel of traditions. Among these was a letter from Mr. Broadfoot, schoolmaster in Pennington, who facetiously signed himself "Clashbottom." To cleish, or clash, is to "flog," in Scots.
