‘other river in Great Britain. Tt appears there in May, and in 
very warm feafons, in April; it continues about two months. 
At its firft appearance, it is efteerned’a very clicate ‘ftth; -efpe~ 
cially at Gloucefter, where it fells dearer than Salmon. The 
London fifhmongers diftinguifh it from that of the Thames by 
the French‘name of Alofe. Whether they {pawn in the Severn 
and Wye, is not determined, as their fry has not yet been af 
certained. The old fifth come from the fea in full roe. 
The fifhermen imagine, very erroneoufly, that the Bleak, 
which appear in multitudes near Gloucefter in the months of 
July and Auguft, are the fry of the Shad: many of thefe are 
taken in thofe months only; but none of the emaciated Shad 
are ever caught in their return. 
The Thames Shad does not frequent the river till the month 
of July, and is thought a very coarfe, infipid fifth. At that 
time, the Twaite, a vatiety of Shad which makes its appearance 
in Gloucefter, and is taken in great numbers in the Severn, but 
held in as great difrepute as the Shad of the Thames. The 
real Shad weighs fometimes eight pounds; but in general 
from four to five. The Twaite,‘on the contrary, ‘weighs 
from half a pound to two pounds, which it never exceeds. It 
only differs from the {mall Shad, by having one or more black 
{pots on its fide, which are generally placed one under the 
other.
