eels crawling over the slippery rocks and squirming in the 
seething whirlpools. An estimate of hundreds of wagon-loads, 
as seen in the course of the perilous journey referred to, would 
hardly be considered excessive by those who have visited the 
spot at a suitable season of the year.’’ “At other times large 
eels may be seen on their way down-stream, although natu- 
rally they ‘are not as conspicuous then as are the hosts of the 
young on their way up-stream. Nevertheless it is now a well-

by Dr. Eigenmann. It is probable that all true eels, Enchely-
