His relations with Swanson and with Ross attest the warmth and constancy of his affections; but the gentleness of his nature does not fully dawn upon us until we read his letters to Miss Dunbar, and understand the friendship which subsisted between him and that lady. She was many years his senior, and as the sister of a Scottish Baronet, Sir Alexander Dunbar, of Boath, and a Tory of the old school, we should have expected her to be shy of poetical masons. Something in Miller's verses, however, attracted her, and a singularly tender and romantic friendship sprung up between them. On his side, it was confined to affectionate appreciation and admiring esteem; but she wrote to him with the tenderness of a mother, and did not scruple to tell him that he was the dearest friend she had in the world. His letters to her are not distinguished by originality or by extraordinary power; but they abound in delineations of nature, poetic in their loveliness; they are just in thought, and faultless in feeling; and in literary style they are perhaps, on the whole, the most melodious and beautiful of his compositions. Like his other writings these letters are full of self-portrayal, and the face which, with pensive, fascinating smile, seems to beam on us from the page, is that of a right noble and loveable man. We feel that this mason is a gentleman; a gentleman of the finest strain; one whose gentleness is of the heart, and manifests itself, not in the polished urbanity of cities which often hides a bad and cold nature, but in a vigilant kindness, a manly deference, and above all a delicate sympathy. The few words of reference to Hugh Miller occurring incidentally in Dr. McCosh's recollections of Bunsen, and published in the biography of the latter--which, by the way, seem to us to cast a more vivid light upon the man than the far lengthier recollections of Miller by Dr. McCosh, printed in Mr. Bayne's biography--specify the intense sweetness and fascination belonging to his presence. Despite his rugged exterior, his shaggy head and rough-hewn features, his mason's apron, his slowly enunciated speech, and his somewhat heavy manner, this fascination was felt by all who had an opportunity of experiencing it.
