return until they mature. They remain in the rivers 

 only three months, and thus nature intervenes to pro- 

 tect them. It is gratifying to know that fish culture 

 in the rivers has annually renewed the shad. The 

 great obstacle to-day that is met with in almost every 

 direction is the hand of man, there cannot be a better 

 exemplification of the value of fish culture than the 

 results with such fish as the shad and salmon. I think 

 Mr. Mather's plaii is an excellent one and his reference 

 to the fact of the increase and poor maintainance of 

 the stock in our waters, by reason of the distribution 

 is right. In our great lake system, we have another 

 thing to contend with, which is that a man has a right 

 to fish throughout the year whenever he can, and this 

 is a great obstacle to the propagation of the fish."
