Appendices to Sixteenth Animal Report 



Pollutions — 



1 and 2. The Town Council of Aberdeen are at present constructing large 

 sewers in the Reclaimed Land, Aberdeen, with combined outfall into 

 the river, by which, if their scheme were to be carried out, the sewerage 

 of extensive and rapidly growing districts of the city would be drained 

 into the Lower Dee, where it is a tidal river. The District Board and 

 the individual proprietors of fishings having objected to the proposed 

 works and intimated their intention of taking proceedings to prevent 

 same from being carried out, negotiations have been and are at present 

 going on, under which it is hoped an amicable and satisfactory arrange- 

 ment will be come to, whereby injury to the river or fishings will be 

 avoided.
