 teristics of the various "stations" will accompany this section, and 

 should be consulted in connection with the text.

 detail, as most of the time was devoted to the beaches which are being 

 formed at the heads of the coves and bays. Quite a variety of condi-

 blocks lowered by sapping, to a shore line with a low angle strewn with
