The Mussel Beds. 



The only mussel beds in the Lune are those at the 

 lower extremity between Glasson and Sunderland Point. 

 One of these, situated on the eastern side of the Estuary, 

 is called Crook Skear; the other "bed" really consists 

 of mussels growing on the stones forming the training 

 wall, extending along the western side of the river from 

 Bazil Point to near Sunderland Point. The shell-fish 

 here are of finer quality than on Crook Skear. There are 

 several smaller patches of mussel ground near the 

 training wall, but the shell-fish here are of very little 

 economic importance. South from Crook Skear, and in 

 the bed of the Estuary, there are also mussels, but these 

 never come adry. 



The Sewer Outfalls. 



The sewer outfalls marked on the chart are those 

 which are referred to in Dr. Sergeant's report to the 

 County Council in 1904. Those lettered A to G 

 discharge mostly domestic sewage, but some manufac- 

 turers' effluents are also carried by them. Sewers 

 H l5 H 2 , and H 3 discharge the domestic sewage and other 

 effluents produced by Messrs. Williamson's mills. 

 Sewer I carries untreated sewage from the Lancaster 

 Infectious Diseases Hospital. All these serve a popula- 

 tion of about 34,000 people. There is no other outfall 

 until Stodday is reached, where a sewer (J), serving a 

 population of about 9,000 people, discharges into the 

 river some distance above low water mark. Two other 

 sewers discharge further down : one (K) at Conder Green 

 opens into a brook which then flows across the sands into 

 the river; the other (L) at Glasson Dock opens into the 

 river directly. The first serves a population of about 

 1,000 people, the latter about 400 people.
