Scarcely had Fielding bent his genius to these new responsibilities of examining Westminster suspects and sending the rogues of that city to prison, than he appears preparing for an extension of those duties over the county of Middlesex. To be a county magistrate in 1750, however, necessitated the holding of landed estate worth £100 per annum; and Fielding's estate, for many years, seems to have been his pen. In this difficulty he turned to the Duke of Bedford, whose public virtues, and private generosity, were so soon to be acknowledged in the Dedication of _Tom Jones_.
