The adventures of an amateur in search of a picture, of a foundling in search of his father, and even of a dog in search of his master, have been severally recorded by skilful pens for the amusement of the public. But, however entertaining or romantic these narratives may be considered, they can hardly surpass in interest the curious history which has just been disclosed of the adventures of an antiquary in search of a ballad-hero. We owe our knowledge of the facts to one of a series of _Critical and Historical Tracts_, by the Rev. Joseph Hunter, now in course of publication. Mr Hunter is an assistant-keeper of the public records, and is well known, by his other publications, as one of the most laborious and most judicious elucidators of mysterious passages in our national history. But the evidences of industry, of minute knowledge, and of logical acuteness, contained in his little treatise concerning 'the ballad-hero, Robin Hood,' are really surprising. The story of an obscure outlaw, who chased deer and took purses in a northern forest five hundred years ago, has been investigated with the painstaking sagacity of a Niebuhr; and a strong light has been unexpectedly thrown on the state of public sentiment and manners existing at that period. Mr Hunter, it is proper to say, dwells in his treatise chiefly upon results, and says little, and that very modestly, of the labours by which they were obtained. He even seems to fear that his subject may be considered trivial, and that he may possibly receive 'the censure of being one who busies himself with the mere playthings of antiquity.' Dr Percy, when he compiled his invaluable Reliques, had similar apprehensions, which were then not altogether groundless; but it may reasonably be hoped, that the race of pedants, who wondered how a man of learning could be interested in a bundle of old ballads, is now extinct.
