in my opinion, are not as good as they should be, then some competent 
person should make an examination of other brooks. 
I do not know at what time of the year the young salmon go down 
past the obstructions named. If they go at low water, when at several 
places the great body of water goes through mill-wheels, many of them 
may be killed ; hence my suggestion of stocking some streams lower 
down. If, however, the fish make the descent of the upper river at 
times of high water they have the choice of going over dams or through 
wheels. However this may be, some have escaped, and the stocking of 
the Hudson with salmon is one of the successes of fish culture with 
which I feel proud to have been connected.
