Anyway the quotation can be read via Google Books Woodbourne - A Novel of the Revolutionary Period, by Joseph Mayo
Colonel Joseph Mayo (1834-1898) was from an old Virginian family which had founded the city of Richmond. From what I can discover online he was a colonel in the Confederate Army during the Civil War, and later on State Treasurer of Virginia in 1872.

The source of Jim Dixon's quote in the London Literary Gazette was William Henry Pyne (1769-1843), writing as Ephraim Hardcastle "a Cockney Greybeard". Pyne was a water colourist who took to writing a series of reminiscences and after dinner gossip in the Gazette, later published in book form as Wine and Walnuts 1823/1824. Steve Roud in Folk Song in England points out that there are reasons to doubt Pyne's veracity. Pyne/Hardcastle claimed however that his mother, Mary Craze, had sung the song to him in his childhood, having learned it in her childhood in the hamlet of Holcombe Rogus, near Tiverton in Devon, so that possibly the original song might be a Devon hunting song of the mid-18th century.
