Of all the historic highways of England, the story of the old Road to Dover is the most difficult to tell. No other road in all Christendom (or Pagandom either, for that matter) has so long and continuous a history, nor one so crowded in every age with incident and associations. The writer, therefore, who has the telling of that story to accomplish is weighted with a heavy sense of responsibility, and though (like a village boy marching fearfully through a midnight churchyard) he whistles to keep his courage warm, yet, for all his outward show of indifference, he keeps an awed glance upon the shadows that beset his path, and is prepared to take to his heels at any moment.
