OYSTER-CULTURAL PROBLEMS OF CONIvTECTICUT, 5 



In general,* conditions became so bad that the planting of oj^^sters 

 in harbors and rivers was no longer profitable except as to such 

 set as might be produced; so bad, in fact, that it was difficult even 

 to maintain oyster beds in these places, and the chance of set pro- 

 duction was very poor. Indeed, water collected in 1918 at various 



locations in one of the more highly industralized harbors was found 

 by Dr. E. P. Churchill, formerly in charge of the bureau's oyster 

 investigations, to be quickly fatal to oyster larvae even when diluted 

 one-half with unpolluted water. This means that to get any ap- 



* New Haven is the principal exception,, but even there much trouble is experienced.
