A couple of eels, one weighing four pounds -- I am thus particular because the weight of a fish is commonly its only title to fame, and these are the only eels I have heard of here; -- also, I have a faint recollection of a little fish some five inches long, with silvery sides and a greenish back, somewhat dace-like in its character, which I mention here chiefly to link my facts to fable.    From Wordnik.com.  [Walden] Reference
