Burns parted with Dugald Stewart, after this evening spent with him in Ayrshire, to meet him again in the Edinburgh coteries, amid which the professor shone as a chief light. Not less important in the history of Burns was his first introduction to Mrs. Dunlop of Dunlop, a lady who continued the constant friend of himself and of his family while she lived. She was said to be a lineal descendant of the brother of the great hero of Scotland, William Wallace. Gilbert Burns gives the following account of the way in (p. 037) which his brother's acquaintance with this lady began. "Of all the friendships, which Robert acquired in Ayrshire or elsewhere, none seemed more agreeable to him than that of Mrs. Dunlop of Dunlop, nor any which has been more uniformly and constantly exerted in behalf of him and his family, of which, were it proper, I could give many instances. Robert was on the point of setting out for Edinburgh before Mrs. Dunlop heard of him. About the time of my brother's publishing in Kilmarnock, she had been afflicted with a long and severe illness, which had reduced her mind to the most distressing state of depression. In this situation, a copy of the printed poems was laid on her table by a friend; and happening to open on _The Cotter's Saturday Night_, she read it over with the greatest pleasure and surprise; the poet's description of the simple cottagers operating on her mind like the charm of a powerful exorcist, expelling the demon _ennui_, and restoring her to her wonted inward harmony and satisfaction. Mrs. Dunlop sent off a person express to Mossgiel, distant fifteen or sixteen miles, with a very obliging letter to my brother, desiring him to send her half a dozen copies of his poems, if he had them to spare, and begging he would do her the pleasure of calling at Dunlop House as soon as convenient. This was the beginning of a correspondence which ended only with the poet's life. Nearly the last use he made with his pen was writing a short letter to this lady a few days before his death."
