FRESH-WATER FISHES OF NEW JERSEY. 109 
the fact of the presence of this fish in a few numbers during 
almost every month of the year. In August when the young 
shad are going down the river, we have seen single speci- 
mens of “smelt,” or “frost-fish,” as they are generally 
called. Occasionally also when fishing for White-perch 
(Morone Americana) we have caught them. In April there 
is very generally a freshet that submerges the tract of mead- 
ows bordering on the river south of Trenton. On the sub- 
sidence of this water the frost-fish are occasionally seen 
with a few herring in the small ditches, and are known then 
by juvenile anglers as the “silver pike.” Hearing frequent 
mention of silver pike, I found this to be the fish referred 
to. Herring that are thus caught in ditches and cut off from 
the creeks do not live, but the Osmerus appears to thrive very 
well. The herring is the " Alewife" (Alosa tyrannus). 
Gizzard Shad (Dorosoma Cepedianum). We gave a short 
notice of this species in the “ Geology of New Jersey,” page

“Occasionally the ‘gizzard shad’ is carried by a freshet into 
inland streams usually having very small outlets, and thus 
imprisoned they thrive very well. A pond near Trenton was, 
in 1857, stocked with them, and is now full of specimens, 
some weighing five pounds apiece.” Besides this pond
