Of Fletcher’s earliest days little is recorded, except that he was, from infancy, of a fiery but generous nature. According to family tradition Burnet imbued his pupil ‘with erudition and the principles of free government’; and perhaps it is not mere fancy which leads us to picture the keen, eager, excitable boy reading the _Book of Martyrs_, and listening to Burnet, who describes his system of education in the account which he gives of the manner in which he taught the Duke of Gloucester in after years. ‘I took,’ he says, ‘to my own province, the reading and explaining the Scriptures to him, the instructing him in the Principles of Religion and the Rules of Virtue, and the giving him a view of History, Geography, Politics, and Government.’ History, politics, and the theory of government--these were, all through his life, Andrew Fletcher’s favourite studies; and we cannot doubt that Burnet not only drilled him thoroughly in Greek and Latin, as he certainly did, but also fostered that taste for letters from which not even the turmoil of politics could ever wean him. Fletcher also owed much to the influence of his mother; and to this he himself, in his later years, bore testimony. ‘One day,’ it is recorded in the private family history, ‘after Andrew Fletcher had entertained his company with a concert of music, and they were walking about in the hall at Saltoun, a gentleman fixed his eye on the picture of Katherine Bruce, where the elegant pencil of Sir Peter Lely had blended the softness and grace that form the pleasing ornaments of the sex. “That is my mother,” says Andrew; “and if there is anything in my education and acquirements during the early part of my life, I owe them entirely to that woman.”’ Burnet remained at Saltoun until November 1669, when he was appointed Professor of Divinity at Glasgow. It is, however, possible that Fletcher was sent to the University of Edinburgh before that date, as the name of an Andrew Fletcher occurs in the University Register for the year 1668. This may not have been young Fletcher of Saltoun; but in any case we would suppose, from the acquirements which he afterwards displayed, that he had received a University education, though this is not to be gathered from Lord Buchan, who says: ‘When he had completed his course of elementary studies in Scotland, under the care of his excellent preceptor, he was sent to travel on the Continent.’ But as Fletcher was only fifteen when Burnet left Saltoun, it seems more probable that he was sent to the University of Edinburgh for a year or two before starting on the ‘Grand Tour.’
