Carp Culture.
| CONTINUED FROM LAST WEEK.

In speaking of The erection of
a breeding establishment for
carp | have in view a water ex-
tent of at least 80 to 30 acres area,
which in Central Europe would
be considered an establishment
of about one-thIrd magnitude.
The inflow of water into the
pond should never be allowed to
be direct; as, for instance, a brook
falling into It. This often causes
the water to rise at an inoppor-
tune time, carrying into the pond
other fishes, especially the rapa-
cious pike. The carp also has
the disposition to swim toward
the inflowing water, by which
means it is drawn away from its
proper feeding places. The Wa
ter should be conducted into the
pond sideways from the stream;
and if it should be a small brook
only. it may be turned off entire
Iy and carried alongside the pond
from which point the latter can
be easily supplied with water.
The inlet :, sluices from the
stream must of course be of a
strong and practical construction,
so that an overflow is impossible,
and they ought TO be provided
with gratings to prevent other
fishes from intruding.
1t is an indispensable condition
for the culture in ponds. accord
ing to established rules, that
they be so constructed as to al
low of being thoroughly drained,
so that the fishes may be taken
out without any difficulty. The
bottom of ponds should be of such
ii description as to permit their
being dried up for agricultural
purposes + necessary.
In Europe ponds Of from 10 to
2,0O0 acres extent are frequently
TO be found, which, after having
been used for tioh-culture for
time, are dried up, and some
times grass, oats, wheat, etc, are
planted on the ground. This inn
proves the soil exceedingly lOr

ply in order to show that the soil

only for fish Sculture but also for
agriculture. If the soil at the
bottom of The ponds has been
freed from the humic acid by
vegetation, after being plowed
and exposed 10 the air thorough

well ln them. This [ extend as
suggestion particularly to farmers
who would wish to establish
small pond of perhaps or 6 acres
size, to show that the soil Of their
land would not lose, but rather
gain hy doing so. Agriculture
and carp-culture go hand in hand

tries, md form a kind Of compile
ment TO one another. To-day a
piece Of ground may be field or
fertile meadow; next wear il will
be found to be productive pond,
to serve again one or TWO years
later its first parpose.
If the size of the principal and
supplementary ponds has been
decided on, the height, depth,
and width must be measured, ,
and the levels of he ground and
dams, if such are needed, should
be- carefully taken. The leveling

In the erection of the required
, dam it is most important that 1t
, be constructed of the very best
material, so as to make it secure
against the destructive influence
of the water. 1t ought to be
three times as wide at its base as
it is high, and at the top the
width should be the same as the
height. The interior or water
side should be less incliued than
the exterior one.
