The late Mr. A. Hadrian Alleroft was an accomplished and
enthusiastic archaeologist who was specially interested in prehistoric earthworks and trackways and loved the South Downs. His intimate knowledge of Sussex is well displayed in a posthumous volume, Waters of Arun (Methuen, 7s. 6d.),
which is designed by the Brighton and Hove Archaeological Club as a memorial to a respected fellow-member. Here, with the aid of a score of maps, Mr. Allcroft has examined the history of the River Arun, above and below Arundel, and shown that its course and its tidal conditions have varied very considerably even within the historic period. As a piece of local research the essay is instructive ; it might serve, too, as a model =for the -leisured- antiquary, since Mr. Allcroft studied the subject both on the ground and in the library. The Sussex coast, as he reminds us, has lost many square miles to the devouring sea ; but, on the other hand, Arundel, like Lewes, once had a port and an overseas trade.
