The young fish for the first few days
need no food, but after the contents of the

they begin to feed, and are then supplied
with clabber, curds, blood, liver aud the
yoIks of hard-boiled eggs, on which they
soon become very lively. IN a few weeks
the young trout need more room, and are
then let into the first pond where, free

to carry home a string.
The plan of artificial breeding used in
regard to fishing has also been employed
with success to promote the growth of
the succulent oyster. The oyster is a
traveller only once in his life. When very
young he floats about seeking some place
where he may find local habitatiOn.
and when he finds it, settles down and
travels no more. To detain the spat of
the oyster almost any sort Of barricade or
restlng-place will serve the purpose.
Posts, fences, screens, chains hung in the
water, brush, stone walls have all been
employed with success. On the Italian
coast the oyster beds are on mounds of
stone which are inclOsed by posts and
close fences. By these the spat are ar
rested and afterward removed to suit
able places of abode. While most of the
oysters used in this country are of arti-
hclal production, the care of their breed
ing has not gone so far as to provide for
the spat, young oysters being brought
from localities where they are known to
abound, and transplanted into water
favorable for their development.
The principal French breeding station,
formerly established in AIsace. is now
owing to the change In ownership, Ger
man training school for fish, and many
German rivers have been restocked from
this establishment; but in lieu of the one
they lost the French have set up a nuTn-
Der on the coast, and all the French
rivers are now well stocked with food
hsh. In Germany, beside the great
ponds already mentioned in Alsace there
are extensive breeding stations at HeideI-
burg, at various points on the Rhine the
Elbe, the Weser, the Main, and num-
Der on the coast, while in Ireland, at the
Skerkin Abbey Lake, large hatcharies
have been established.
One of the largest salmon hatcheries in
the world is on the Tay in Scotland
where 1t has been in operation many
y CebAo w hAtA1 ssOONA 1CSll1G over OUO ndlCh-
ing troughs are in continual use, the fish
as soon as possible being dismissed from
the hatcheries to large ponds connected
with the river. From this hatchery
thousands of fish are sent to market
every year, and great numbers of fry de-
posted to stock the mountain streams of
England and Scotland.
In Norway experiments have been con-
Quoted on a grand scale, which more
nearly than elsewhere approaches the
conditions of nature. Whole tiorCs. or
bays, have been inclosed with wire net
ting, and natural lakes, found high lp i'm
the Norway hills, have been cleared of
their former finny inhabitants and turned
into breeding ponds. One such breedinp
basin covers an area of over 800 acres. and
millions of young fry are hatched, and
in this, and the lower ponds, and the
arms Of the sea, are brought to full deyel-
Opment.
In Canada, near Newcastle. Ontario
there is one of the most successful sal
mon hatcheries in the world. So exten-
sive has been the fishing through the
lakes and the mountain streams to the
north and south that during late wears
the salmon had almost completely disnD-
peared, but by means OF this hatchery
not only the streams, but even the lakes.
were resuppled with excellent fish, and
now the fishing is good where ten wears
ago not fin cut the surface.
Experiments in tish-hatching in this
country have been extensive, and meas
urably successful, though not in pecuni-
airy way. In a matter Of this kind, how
ever, a little expenditure iudiciouslv
made is often amply rewarded in few
years. If he is deserving of credit who
makes two blades OF grass grow where
only one grew before, much more entitled
to the praises of his feilowmen is he who
stocks the otherwise useless streams with
cheap and excellent article of food.
The results of the labors of our Fish
Commissioners, while not eaualing
those attained in Europe, are neverthc-
less highly creditabIe, and it is but a
question of time when from our Govern
ment ponds and hatcheries every stream
in the United States will be provided
with an ample supply Of excellent food
