Usually a silent topic, the author presents a discussion on 

 the terminal groin of a system. Until a solution is devised that 

 eill end the scour of the terminal groin, it is suggested that 

 permeable lateral works, wave screens, faggoting, and groins (as 

 low as possible) be employed to keep erosion at a minimum. Faggot- 

 work groins, used to reduce irregularities caused by groins in 

 shingle banks, are given special attention.
