 obtained from the thatch near by. Perhaps it may be repeated that the 

 beach on the southern exposure of Fields Point, for a distance of more 

 than a quarter of a mile from the sewer outlet, is covered with foul-

 the rising tide is charged with sewage matters, and leaves a deposit 

 of slime on the rocks and shore below the low-water mark and a trail 

 of filth and organic refuse along the high-water line. 



The results of the analysis of these shellfish are given in the follow- 

 ing table:
