 into Jamaica Bay. 



By studying the accompanying maps and illustrations (PI. II and 

 fig. 5) it will be seen that Jamaica Bay is located dangerously near a 

 large city and into it many million gallons of sewage empty daily. 



In addition to the published report of the New York State Board of
