 and millions are annually taken by the fishermen ; 

 and in connexion with these facts, it is admit-

 herring in all its migrations, to destroy it ; the 

 havoc made on their phalanxes by other fishes 

 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
