can be conducted in the future, so long as we can secure 

 the valuable co-operation of the I'. S. Government. 



It is quite possible that the period of the runs of Shad 

 in the rivers has a close relation to the time in which the 

 young fish are originally hatched, and the early run may 

 possibly be the result of the hsh Avliich are first hatched 

 in any given season. 



The disturbance of the tish for many years by seines and 

 gill-nets has interfered materially with the production 

 of young from the earliest spawners, and from this cause 

 the early runs were gradually becoming exhausted. 

 It is possible that as by artificial prox)agation we 

 have been able to deposit young fish, produced from 

 spawn taken from the early runs, the earlier schools have 

 been increased, and we are not now de^^endent solely for 

 the supply of the future upon the limited number of fish 

 produced by the late runs, which spawn after the season 

 is so far advanced that most of the seines and gill-nets 

 have ceased their operations.
