229 REPORT OF THE COMMISSIONER OF FISHERIES. 
Fields Point, contained B. col7, either in the juice or in the intestines. 
In one case the stomach was found sterile; in another, the stomach 
tests did not give the reactions for this organism; ina third, however, 
B. coli was isolated from tubes inoculated with material from the 
stomach. The bacillus was not found in the rectum of the one oyster 
examined in this respect. Bact. lactis aerogenes and L. sporogenes 
were observed in the tests from the juice and intestines of a number 
of the specimens. . 
The majority of the oysters, clams, and mussels taken from the Proy- 
idence River at a distance of about 2 miles from the sewer outlet con- 
tain evidences of sewage pollution. As might be expected, however, 
fewer samples from the eastern side of the river than from the western 
were found infected. About 70 per cent of the oysters from the 
Sabins Point bed contained 2. col7, while practically all of the clams 
and mussels from Pawtuxet were contaminated. 
The next batch of oysters examined was obtained from the Bullock 
Neck ground off the eastern shore of the river, not far from the Bul- 
lock Point light, about 4 miles below Fields Point. These oysters 
were dredged in from 18 to 20 feet of water and were obtained fresh 
from the boats working over the beds. Three lots were taken from 
this locality; in all 15 oysters were examined. Table XI is a record 
of this analysis.
