lines carrying passengers to this district, the population in this district on certain days 

 may reach as high as 125,000 to 150,000. 



Twenty-nine public sewers discharge sewage from this varying population directly 

 into Jamaica Bay. 



By studying the accompanying maps and illustrations (PL 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

On January 25, 1912, an inspection was made of the Hendrix 

 Street sewage disposal plant, located at the foot of Hendrix Street,
