are, as a rule, of rather poor quality. The mussels taken 

 from the river at Hambleton are well-known and fetch 

 a very good price. Those raked from the bed of the river 

 are very fine shell-fish, hut those on the foreshore are 

 rather poor in quality. 



The Sewer Outfalls. 



Formerly all the sewage of Fleetwood, representing 

 a population of about 15,000 people, was discharged into 

 the Wyre between the Ferry and Docks, through various 

 outfalls. At the present time it is diverted from these 

 old outfalls and taken across the Fylde peninsula to a 

 pumping station near Rossall. The outfalls 6 and 7 on 

 the chart are near Rossall Landmark, much further 

 seawards than is shown on the chart, and is thus com- 

 pletely removed from any influence upon the shell-fish 

 beds of the Wyre. There are, however, several other 

 sources of pollution. There are several small drains on 

 the Knott-End side of the Estuary, near to the Ferry, 

 but these need not concern us here. On the Fleetwood 

 side there are two sewers (1) a small drain from an ice 

 factory, and (2) a storm overflow from the main system. 

 Further down the estuary, near the Docks, are three 

 drains conveying manufacturing effluents ; (3) comes 

 from a fish-oil works ; (4) from a fish-curing house ; and 

 (5) from a " fish-meal" works. There are iron pipes 

 terminating well above low water mark, on the beach, 

 so that the effluent reaches the estuary by little brooks 

 flowing right through the mussel beds — at this point, 

 however, the shell-fish are very small and are rarely 

 fished. 



The sewage from Hambleton appears to drain into 

 the small becks entering the estuary here. That from 

 Poulton-le-Fylde enters into a little brook called Peg's 

 Pool : this is the outfall marked (8) on the chart.
