" This interesting species is more or less abundant in the 

 principal rivers of the State. In the Delaware they are numer- 

 ous, and entering the Delaware and Raritan Canal at Borden- 

 town, find their way into the basins, where they are left in winter 

 when navigation is closed and the water in the canal is drawn off."
