The talus begins at 575 

 feet above sea-level. It is 

 composed almost entirely 

 of basaltic debris and is 

 traversed by the water- 

 courses streaming down 

 from the rocks above. The 

 angle of this talus varies 

 with its height : for the 

 first quarter of its descent 

 it is about 44° or 45° ; for 

 the next about 38° ; lower 

 down it becomes 25° and 

 20°. It finally slopes at a 

 gentle angle on to the raised 

 beach. 



Raised beaches of various 

 heights occur at Cape Plora. 

 Thus Elmwood is situ- 

 ated on a well-marked 

 beach which slopes gently 

 from 50 to 36 feet. This 

 beach is prolonged into an 

 apron-like front having an 

 area of about 3 or 4 acres. 

 The surface is strewn with 

 large and small waterworn 

 boulders. Some portions 

 are carpeted with a rich 

 growth of moss, grass, 

 lichens, and other plants ; 

 certain parts are formed 

 of bare ground or soft- 

 tenacious mud. Many 

 other beaches besides that 

 on which Elmwood stands 

 may be recognized at Cape 

 Flora. At the north-west- 

 ern point of the Cape well- 

 marked terraces occur at 

 30, 35, and 80 feet above 

 sea-level ; and between this 

 point and Elmwood others 

 may be observed at 8, 29, 

 45, 54, and 65 feet. The 

 highest terrace is that onto 

 which the talus descends. 

 Further particulars regard- 

 ing raised beaches will be 

 given in a later part of this 

 communication (p. 638).
