AMPREYS are found at certain feafons of 

 the year in feveral of our rivers, but the Severn 

 is the mod noted for them *. They are fea fifh, 

 but like falmon, quit the fait waters, and afcend 

 Place. the latter end of the winter, or beginning of fpring, 

 and after a (lay of a few months return again to the 

 ocean, a very few excepted. The bed feafon for 

 them is in the months of March., Aprils and May \ 

 for they are more firm when juft arrived out of 

 the fait water than they are afterwards, being ob- 

 ferved to be much wailed, and very flabby at the 

 approach of hot weather. 



* They are alfo found in the mofl confiderable of the Scotch 

 and Irifo rivers.
