The study of earthworks has been one of the most neglected subjects in English archæology until quite recent years. It may even be said that during the first half of the 19th century, less attention was paid to earthworks than by our older topographical writers. Leland, in the reign of Henry VIII., never failed to notice the “Dikes and Hilles, which were Campes of Men of Warre,” nor the “Hilles of Yerth cast up like the Dungeon of sum olde Castelle,” which he saw in his pilgrimages through England. And many of our 17th- and 18th-century topographers have left us invaluable notices of earthworks which were extant in their time. But if we turn over the archæological journals of some fifty years ago, we shall be struck by the paucity of papers on earthworks, and especially by the complete ignoring, in most cases, of those connected with castles.
