The Aberdovey Tank. 



The original scheme for the construction of this tank 

 has had to be abandoned because of objections urged by the

 the Board of Trade may prove workable. Several inspections 

 have been made at Aberdovey, and a conference between

 The condition of the mussels on this scar is not satisfactory.

 mussel purification schemes of the Lune Estuary has been 

 dropped — partly, no doubt, because of the increasing difficulty 

 of maintaining the sanitary services, and partly because the 

 musselling industry in this locality has greatly depreciated. 

 Several series of analyses have, however, been made. 



For some reason or other attention was drawn to the 

 condition of the water of the Lune Estuary. Analyses were
