-LiAMPREYS are found at certain seasons of 

 the year in several of our rivers, but the Severn 

 is the most noted for them.* They are a sea 

 fish, but, like salmon, quit the salt waters, and 

 ascend rivers the latter end of the winter, or 

 beginning of spring, and after a stay of a few 

 months return again to the ocean, a very few 



* They are also found in the most considerable of the Scotch 

 and Irish rivers.
