THE PROPAGATION OF TROUT,
} The Editor Of the New York Tribune

Overwhelmed Win ietters from di paris Vi
the United States, asking further information
in the various departments OF their cultiva-
ton. This great desire for further knowi-
edge. 10 extensively manifested by large
number Of your readers, induces me TO ask
you TO print the following article, in the
different editions Of the Tribune. giving
minute answers TO the most important in
formation required in growing Trout, both
naturally and artifcially. Also a pretty
full description Of the celebrated Caledonia
Spring Creek, the vast number Of Trout it
yearly produces naturally, with Seth Green's
gigantic operations in growing Trout in it
artifcially, dc.
To cultivate Brook Trout successfully, the
water must be pure, clean spring water, free
from ell sediment but atincture Of lime, or
sulphur, does no harm, as far as l have been
able to discover in six years observation and
practice. ] have seen them hatch and four

The temperature Of the waterin thehatch-
ing races, or troughs, during the time of in
cubation must be between thirty-six to forty
eight degrees 10 insure success. The best
temperature, in my opinion, all things con-
sidered, is from forty-two 10 forty-iive de-
grees. When above this temperature they
hatch too soon, andare too weak and tender.

year round.
Trout will not do we'll where the water
rises in the summer abovesixty or sixty-four
degrees at mos.- The best temperature to
grow them TO perfection is between fifty and
ffty-eight degrees.
This fact should be always borne in mind
when constructing ponds, so as TO have the
size Of the ponds correspond with the volume
Of water in the stream supplying them.
For example: A spring that produces as
much water as will run through an inch
square hole, will supply pond twenty by
thirty feet square, or six hundred square
feet surface, and keep the water belowsixty-
four degrees through the summer, and if
covered with house or boards, so as to
shade the water efectually, it may be double
that size. / have one of this size shaded,
supplied with an inch stream, and the tenn
perature never rises above sixty-four degrees,
and the Trout are always perfectly healthy

inch square hole, the the pond may be six
teen times as large, containing 5000 square
feet, or pond eighty by one hundred and
twenty square feet, and 30 on, according to
the size Of the stream.
For growing large Trout, the water should
be from s TO Is feet deep, for small ones,
from 2 inches TO feet, according TO the
size Of the Trout. An inch stream running
through two perfectly arranged Matching
troughs, will hatch 5000 spawn, and grow
them till about inches long, when part
Of them, from lime to time, must be put into
\ other streams. This stream will grow TO-
600 Trout the first year, 1000 the second
year, and 500 the third year, thus decreas-
ing rapidly in number as they increase in
size.
A l6-inch stream might hatch 100000
Trout; grow 100000 the first year, $4,000
the second year, and 5000 the third year,
and 1900 or 1900 the fourth year that
would average one pound each.
Young Trout till from one TO two inches
long, do much the best in shallow water,
say from inches 10 inches deep, but as
they increase in size the water should be in
creased in depth. BY the first Of Novem-
Der, if we'll fed, they will be from inches
10 inches long. AT this time the water
NAV be increased to the depth Of three feet
The most difficult period in growing trout
artifcially is about the time they commence
feeding This period is from 40 to 60 days
after Matching, according TO the tempera-
ture Of the water. At this time large pro-

To obviate this, put tank twelve feet

into the tank, where they can rest in still
water from two 10 three inches deep. In
this way they will soon recover and
come into the very slight current to look for
food and, as they grow stronger, run up the
haiching-box again. BY this arrangement
