124 FISHERIES OF THE NORTH SEA 



shore for transmission to the English 

 markets, thus warning owners of their 

 movements. 



Lying midway between Iceland and 

 Ireland, far out in the Atlantic, is the 

 submerged bank of Rockall. This range 

 of submarine mountains culminates in a 

 single point of rock, only 70 feet above 

 sea-level, of granitic formation, with a 

 circumference of 250 feet. It is, of course, 

 uninhabited, and landing is exceedingly 

 difficult. The rock is easily seen by 

 trawlers, for its sugar-loaf summit is made 

 white by birds, and the sea breaks over the 

 reefs around it with terrible force. When 

 discovered by fishermen the ground was a 

 fertile bank populated by cod-fish and 

 plaice of enormous size and very light 

 colour, the inference being that the banks 

 are composed mostly of quartz or felspar. 

 These banks have been little fished since 

 war broke up the trawling industry, and 

 should therefore be a valuable fishery 

 as soon as it is possible to recommence 

 operations.
