 and millions are annually taken by the fishermen ; 

 — and in connexion with these facts, it is admit-

 and marine monsters, — and yet their numbers 

 appearing, undiminished; — with all these facts, 

 can any man in his senses, doubt for a moment, 

 the relations of naturalists. 



In direct opposition to the foregoing remarks, 

 the migratory character of the herring is ques- 

 tioned by some very late writers, who suppose it 

 remains through the winter at no great distance 

 from the shore, or plunges into the deepest parts 

 of the ocean, or burrows in the mud, to rise at the 

 spawning season. All this appears both unphilo-
