HERM. 



The island of Herra is situated about 3 miles from the east 

 coast of Guernsey, from which it is separated by a narrow 

 channel, the Little Russel, in which the sea presents exceed-

 than half a mile broad and nearly 2 miles in length. The 

 coast, which is nearly perpendicular to the east and especially 

 towards the south, falls with a gentle slope to the north and 

 west. On the west coast the sea in retiring lays bare an 

 immense sandy beach, which extends at spring-tides to a 

 distance of more than half a mile. Thus the surface of the
