Mr. Farrsanks—They all increase very largely after 
the putting in first begins. 
Dr. Hupson—Yes; though they have been putting 
them in very large numbers of recent years ; some fifteen, 
twenty, thirty or forty millions every year up to about 
two years ago. 
Mr. BowmMan—Were those brought from other places ? ° 
Mr. Hupson—Yes. The work has been going on 
constantly. There is another reason which has been 
alleged. The fishermen allege this as one reason why the 
shad do not come into the Connecticut, namely, the 
breakwater which has been built near the mouth of that 
river by the U. S. Government for the purpose of increas- 
ing the depth of the outflow over the bar. They claimed 
that the effect of that is to send the water directly into 
the Sound instead of to the West as formerly ; therefore 
they think that may have thrown the shad into some other 
river, from the fact that further to the West towards New 
Haven some of the men take a great deal more than 
they do. 
Mr. Bowman—Can it not be that there is contamina- 
tion in the water. 
Dr. Hupson—As I was saying before, the Connecti- 
cut being a small river it may be more easily affected by 
contamination. 
Mr. JAames—Of course there is a question whether 
any contamination has been noticed along the river. 
Dr. Hupson—There never has been in regards to shad, 
but as to small fish there has been; carp and dace and 
such things, but not with the shad. 
Mr. Forp—The proof of Dr. Hudson’s remarks has 
been borne out by our experience in the Susquehanna 
and the Delaware. In the fourteen miles of the Susque- 
hanna within the State of Maryland there are hundreds 
of fishers that catch the young shad as they go down to 
the sea, and with the pound nets in the mouth of the 
river, there has been a constant and continual decrease in
