 from a river, making its way to it Rke a snake

 is perhaps more uncommon, we have watched an 

 eel rising repeatedly to the surface of a stream to

 young ones which migrate from those ponds every 

 year. We are assured that at nearly the same 

 day, in the month of May, vast numbers of young 

 eels, about two inches in length, contrived to get 

 through the pen-stock of the upper pond, and
