Yellow Perch.—Is everywhere well known as a beautiful little fresh-water fish, and good for the table, at all seasons when the water is cool. Perfectly hardy and adapted to sluggish waters, it is one of the best for artificial ponds. Treat like all the preceding; or allowed to take its own course in the pond, it will increase rapidly.
Sun-Fish.—Rarely weighs more than half a pound, but is a good pan-fish. This and the grass bass and yellow perch may be put together in the same pond.
Eels.—May be cultivated with great success in almost any water. But we are so prejudiced against them, never consenting to taste one, that we can not speak in their favor. Of the methods of introducing fish into our rivers and creeks, from which they have nearly all been taken by the fishermen, it is not our design to treat. That subject may be found fully presented in treatises on fish culture, and should command the immediate attention of the authorities in all the states.
We have here given all that is necessary to success among the masses all over the land. There is hardly a township in the United States or British provinces, where good fish-ponds might not be constructed so as to be a source of profit and luxury to the inhabitants.
Fish are so certainly and easily raised, that the practice of cultivating them should be universally adopted.
Transporting fish alive is somewhat hazardous, especially if they be of considerable size. The difficulty is greatly lessened by keeping ice in the water with the fish. Change water twice a day and keep ice in it, and you may safely transport fish around the globe. Eggs of fish are best transported in boxes six inches square, filled with alternate layers of sand and eggs scattered over. When full, make quite wet, and fasten on the cover. Other methods are adopted which will be easily learned of those engaged in the trade.
FLAX.
Change the seed every season. This will greatly increase the quantity, and improve the quality. In nothing else is it more important. In Ireland, the great flax-growing country of the world, they always sow foreign seed when it can be procured. American seed is preferred, and brings the highest price. Experiments with different seeds, on varieties of soils, are much needed. Changing from all the soils and latitudes of our country would be useful. The general rule, however, as with all seeds, is to change from colder to warmer regions.
Soils.—The best are strong alluvial soils. Any soil good for a garden is good for flax. As much clay as will allow soil soon to become dry and easily to be made mellow, is desirable; black loam, with hard, poor clay-subsoil, is also good. Mellow, friable soils are not more important to any other crop than to flax. Land must not be worked when too wet. The land should be rich from a previous year's manuring. Salt, lime, ashes, and plaster, are good applications to flax after it has come up. On light soil with bad tillage, when the flax was so poor that the cultivator was about to plow it up, the application of three bushels of plaster, in the morning when the dew was on, produced a larger yield of better flax from an acre than adjoining growers got from two acres of their best land.
