. American farming and stock raising, with useful facts for the household, devoted to farming in all its departments. Agriculture. FISH CULTURE. 1757 and is most convenient for changing the fish from one pond to another. It is not necessary that the ponds shouki be in a straiglit hue. Where the location demands it, they may be turned so as to he in a direction nearly or quite parallel with one another. This is easily done by bending the raceways, and lengthening them if necessary, only a curved raceway is sometimes not so convenient as if it were straight. The sides of the ponds may be walled up with stones, laid without mortar, unless the soil is very sandy. Wood may be better for the sides and bottoms, but we are inclined to think is not worth its expense. If the sides of the ponds are laid up with mortar, let it dry thoroughly before letting the water in; then let the water run through it two or three weeks, or long enough to purify the pond before putting any fish in it. It is as well to tost it by putting in only a few lish at first'; if the pond is not thoroughly purified, the fish in it will turn blind. Ponds should not be built where much surface drainage will run into them; if they are so exposed, the surface water should be carried off by a ditch around them. The second and thii'd ponds should receive an additional supply of water. If tlie supply of water is small, it is best to have as much fall betwi-en the ponds as the natm-e of the ground will allow This fall aerates the water, and makes it as goud as HATCHING HOUSE, NURSERY, AND POND. Shape of Ponds. — Where the supply of water is large, it matters very little about the shape of the ponds. The best shape we believe to be the pear shape, such a shape com- bining an equable flow of water in all directions, and the greatest amount of surface with the least difference in the temperature of the water. If the nature of the ground demands other shapes, the ponds should be made long, narrow, and deep,
