pieces of old stakes thickly covered with Mussels, of all 
sizes, were removed from the scars and fixed in the struc- 
ture, but in a very short time all had disappeared. A 
further trial will, however, be given it during the present 
year, and, as soon as possible, it is intended to re-stock it.” 
NoTES ON THE SHAD. 
(By Mr. R. L. Ascrort.) 
Tuts fish, whose scientific name is ‘‘Clupea alosa,”’ 
belongs (as that appelation imports) to the Herring tribe. 
It is found in the Mediterranean and along the Atlantic 
and North Sea coasts of Europe, as far as Jutland. In 
this country it is plentiful in the Severn, and I have 
taken several on the Lancashire coast in a mackerel baulk 
at Formby. The Shad must have been numerous on the

was that one thousand Shad be delivered to the lessor by 
the lessee during the Shad season (Sceadda dagen), and,

the Shrimp nets in the Lancashire district are called Shad 
by the fishermen.

its migration up the rivers for a short distance above the 
tidal waters to spawn. It enters the rivers in Holland 
from the middle of March to the middle of June, and

above Worcester. The eggs, which are heavier than

The pair swim at night at or near the surface of the
