One of the grandest figures that ever frequented Eastern Yorkshire was William Smith, the distinguished Father of English Geology. My boyish reminiscence of the old engineer, as he sketched a triangle on the flags of our yard, and taught me how to measure it, is very vivid. The drab knee-breeches and grey worsted stockings, the deep waistcoat, with its pockets well furnished with snuff-of which ample quantities continually disappeared within the finely chiselled nostril-and the dark coat with its rounded outline and somewhat quakerish cut, are all clearly present to my memory.
