addition to these, there is a scar at the extreme northern 

 end of Barrow Channel, at the place known as Scarth 

 Hole. This bed is not shown in the chart. 



The Conishead Priory mussel bed, which is not 

 shown on the chart, is situated about seven miles to the 

 north of the Roosebeck Scar. A shallow-water channel, 

 Ulverston Channel, extends from Roosebeck right up to 

 Ulverston, and this never dries. It varies in width at 

 low water from about 50 to 70 feet. The Conishead 

 Priory bed is situated on the foreshore locally known as 

 Cope Scar, on the western side of the channel, and about 

 one mile below Ulverston. It is a bed of very little 

 economic importance and is not fished at the present 

 time. 



None of the Barrow Channel beds is regularly fished. 

 At very rare times mussels have been taken from the 

 foreshore near Piel, and from the bed in Scarth Hole. 

 Such occasional fishing may occur, during periods of 

 unemployment, by persons who are not fishermen : for 

 instance, during the winter of 1908-9, when there was 

 much unemployment in Barrow. There is always, of 

 course, the possibility of these mussels being taken by 

 trippers, or by local people, for other purposes than 

 marketing. But so far as the public food supply is 

 concerned, the only one of this group of mussel beds that 

 matters is that at Roosebeck, and a proper fishery only 

 occurs here rather infrequently. 



The Sewer Outfalls. 



All the sewage of Ulverston, representing a 

 population of about 10,000, enters the sea, practically 

 untreated, by an outfall situated at the head of a little 

 creek. This creek opens into Ulverston Channel about 

 a quarter of a mile south of the sewer outfall, and about
