 control of the Lancashire Sea-Fisheries Committee, extend 

 from a little way south-east of the town of Morecambe, to 

 a considerable distance beyond the village of Heysham 

 and are partly continuous with the shore. In front of 

 Heysham, they are separated at low water into three sep- 

 arate banks, the outer one tailing off into the deep-water at 

 the entrance to Heysham Lake. The Mussel scar separates 

 the deep-water into two distinct channels, the outer being

 mussel rakes. At the time the examination was made no
