AMPREYS are fotind at certain feafons of 
the year in feveral of our rivers, but the Severn 
is the moft noted for them*. ‘They are fea fith, 
but like falmon, quit the falt waters, and afcend the 
latter end’ of the winter, or beginning of fpring, 
and after a ftay of a few moriths return again to the 
ocean, a very few excepted. The beft feafon for 
them is the months of March, April, and May; 
for they are more firm when juft arrived out of the 
falt water than they are afterwards, being obferved 
to be much wafted, and very flabby at the approach 
of hot weather. 
They aretaken in the nets along with falmon and 
fhad, and fometimes in weels laid in the bottom of 
the river. 
* They are alfo found in the melt confiderable of the Sects 
and Zri/e rivers. i
