and down Channel over other scars ; earlier on the ebb 

 tide the stream will flow over the first scar. 



At Morecambe and Heysham there are in all eight 

 sewer outlets, all of which discharge some considerable 

 distance away from the principal Heysham Mussel Beds. 

 At the same time, three of them empty close to where 

 sizeable Mussels can be taken in payable quantities. I 

 understand; however, it is the intention of the Authorities 

 to turn all the Morecambe sewage out through a new pipe, 

 which is now laid down and in use, and to do away with the 

 old sewers referred to. With regard to the new sewer 

 outlet, it does not, to my mind, project far enough into the 

 channel, and should be carried about 75 yards farther out. 

 It discharges on a scar which, although not a main bed, is 

 one where sizeable Mussels can be obtained in fair 

 quantities, and this scar might easily become well stocked 

 with fish. The fishermen agree that the sewer outlet 

 should be carried farther out. I may also draw attention 

 to the fact that, at the time I refer to, the sewage was being- 

 discharged at low water, and, although some of it is 

 supposed to be treated, what we saw appeared to me to be 

 untreated. 



In the Lune the sewers discharge a considerable 

 distance up the river, above the Mussel Beds; and 

 although they join the main stream which flows alongside 

 and, in some states of the tide, over Mussel Beds, there 

 was nothing we saw that, in my opinion, exposed the fish 

 to serious danger of contamination. In the Wyre, with 

 the exception of a sewer outlet at Knott End, the sewage 

 is discharged on the Fleetwood side of the river, and some 

 distance from the Mussel Beds. In the Ribble the Preston 

 sewage is dealt with at the sewage farm ; but at Lytham 

 the sewage joins the main stream and together they flow 

 on over the Mussels attached to the training walls, and
