arrange boxes in the form of steps, the top one being supplied
with water by a fountain, and that passing from one to the other through
all the series, and the eggs placed on willow-hurdles instead of gravel.

Another very simple method may be arranged in the house. It is a
reservoir--a barrel or cask--set perhaps two and a half feet from the
floor, and a little hatching trough a few inches lower, into which water
gradually runs through a faucet, from the reservoir. This water running
through the hatching-box, escapes into a tub a little below. Whatever
plan be adopted, great care is necessary in preventing sediment from
depositing. Cleanliness is a principal condition of success. The eggs of
the trout thus fecundated and deposited in October or November will
hatch in the spring. Young trout need no feeding for a month after
leaving the egg. There is a small bladder or vesicle under the fore part
of the body, when they first come out, from which they derive their
sustenance. After this disappears, or at the end of about a month, they
should be fed, in very small quantities. Too much will leave a portion
to decay on the bottom and injure the water. The best possible food
(except the angle-worm) is lean flesh of animals, boiled and hashed fine
for the young fish. The flesh of other kinds of fish, when they are
plenty and not very valuable, would be very good. These young fish
should be kept in the first pond until a year old. Then let them into
the second pond, closing the gate after them, to make room for another
brood in the first pond. The next year let them into the third, and
those into the second that are now in the first, and so on till the
fourth. In the last pond, those of different ages will all be large
enough to take care of themselves. But sometimes a trout two years old
is said to swallow one a year old. But when they get to be three or four
years old, this sort of cannibalism ceases. These principles can be
carried out in small streams, by constructing gates to keep sections
separate, and by forming banks and waste ways for water, with wire gates
so high, that the water will not overflow in freshets, and carry the
fish away. In taking trout use angle-worms or the fly. A fine
light-colored small line is best. They are very shy. The following is a
list of other fish, beside the trout, that are well worthy of
cultivation:--

_Black Bass._--When full grown, this fish is from twelve to eighteen
inches in lengt
