{p.128} Mr. Murray, gladly embracing this offer of an article for his journal on the Tales of my Landlord, begged Scott to take a wider scope, and dropping all respect for the idea of a divided parentage, to place together any materials he might have for the illustration of the Waverley Novels in general; he suggested in particular, that, instead of drawing up a long-promised disquisition on the Gypsies in a separate shape, whatever he had to say concerning that picturesque generation might be introduced by way of comment on the character of Meg Merrilies. What Scott's original conception had been I know not; he certainly gave his reviewal all the breadth which Murray could have wished, and, _inter alia_, diversified it with a few anecdotes of the Scottish Gypsies. But the late excellent biographer of John Knox, Dr. Thomas M'Crie, had, in the mean time, considered the representation of the Covenanters, in the story of Old Mortality, as so unfair as to demand at his {p.129} hands a very serious rebuke. The Doctor forthwith published, in a magazine called the Edinburgh Christian Instructor, a set of papers, in which the historical foundations of that tale were attacked with indignant warmth; and though Scott, when he first heard of these invectives, expressed his resolution never even to read them, he found the impression they were producing so strong, that he soon changed his purpose, and finally devoted a very large part of his article for the Quarterly Review to an elaborate defence of his own picture of the Covenanters.[51]
