The sides of the ponds may be walled upwith stones, laid without mortar, unless the soil is very sandy. Wood may be better for thesides and bottoms, but we are inclined to think is not worth its expense. If the sides of theponds are laid up with mortar, let it dry thoroughly before letting the water in; then let thewater run through it two or three weeks, or long enough to purify the pond before puttingany fish in it. It is as well to test it by putting in only a few fish at first; if the pond is notthoroughly purified, the fish in it will turn blind. Ponds should not be built where muchsurface drainage will run into them; if they are so exposed, the surface water should becarried off by a ditch around them. The second and third ponds should receive an additionalBupply of water. If the supply of water is small, it is best to have as much fall between theponds as the nature of the ground will allow. This fall aerates the water, and makes it asgood as new.. HATCHING HOUSE, NURSERY, AND POND. Shape of Ponds. — Where the supply of water is large, it matters very little aboutthe 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 theleast difference in the temperature of the water. If the nature of the ground demands othershapes, the ponds should be made long, narrow, and deep, rather than broad and shallow.The depth of the first pond should be 2 feet, the second 4 feet, and the third 5 feet. Thesedepths will answer for any size of ponds. It is better for any one wishing to raise a largenumber of fish, to have several series of ponds, than to attempt raising a larger number byincreasing the size of the ponds. Fish do not feed so well in large ponds, are not so easilytaken
