Shellfish and Pollution. 



The state of the law in regard to the pollution oi 

 shell-fish beds by sewage is still a menace to the public- 

 health and a reproach to civilisation. The necessary 

 legislative reform will no doubt come sooner or later ; 

 but if the Sea-Fisheries Local Authorities can do 

 anything further to secure more immediate attention to 

 the evil and to insure its removal this year or next year 

 in place of a decade hence, their action will deserve the 

 gratitude of the community they represent and will 

 receive the approval of posterity.
