concrete cleansing tank of 40,000 gallons capacity. 

 The mussels are first thoroughly hosed with water at 

 high pressure to remove all adherent mud, etc. The 

 tank is then filled with sterilized sea-water and the 

 mussels are allowed to remain in it for 24 hours. During 

 this period the mussels effectually free themselves from 

 bacteria. The tank is then emptied, the mussels are 

 hosed again, the tank is again filled with sterile water 

 and after a further 24 hours is emptied. The mussels 

 are once more flushed with the hose. After this treat- 

 ment the mussels reach a high standard of purity. 

 The scheme has proved to be a complete success, not only 

 from a scientific point of view, but also as a commercial 

 proposition. The sum of Is. per bag of mussels (140 Ibs.) 

 is charged to the fishermen for this treatment.
