AMPREYS are found at certain feafons of 

 the year in feveral of our rivers, hut \h& Severn 

 is the moft noted for them *, They are fea fifh, 

 but like falmon, quit the fait waters, and afcend 

 Placi. 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, April, and May - 9 

 for they are more firm when juft arrived out of 

 the fait water than they are afterwards, being ob- 

 ferved to be much wafted, and very flabby at the 

 approach of hot weather. 



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

 and Irijb rivers.
