This is a hardy biennial vegetable, resembling a small parsnip, and as easily grown. When properly cooked, its flavor resembles the oyster, whence its name. Sow and cultivate as parsnips or carrots. It is suitable for use from November to May. It is better for being allowed to remain in the ground until wanted for use, though it may be well kept, in moist sand in the cellar. Care is necessary in saving seed as it shells and blows away like thistle seed, as soon as ripe. It must be sown quite thick, on account of its proneness not to vegetate. It should be more extensively cultivated. SCRAPING LAND. This is a process needed only on land that has not been under cultivation long enough to become level. All new land has many knolls of greater or less size. As soon as the roots are out sufficiently to allow it, the knolls should be plowed and leveled with a common scraper. Most farmers neglect it as injurious to the soil, and too expensive. But when we consider that rough land never gets well plowed, and that the gradual wearing away of the knolls will continue their unproductiveness for a number of years, it will be seen that the cheapest way is to plow and scrape the land level at once, and thoroughly manure the places from which the soil has been scraped. SEEDS. The best of everything should be saved for seed. Peas, beans, corn, tomatoes, &c., should not be gathered promiscuously, finally preserving the last that matures, for seed. Leave some of the finest and earliest stocks, and from them save seed, not from the first or the last that matures, but from the earliest that grows large and fair. Save tomato-seed from those that grow largest, but near the root. Gather all seeds as soon as mature, as remaining exposed to the weather is unfavorable to vegetation. Dry in a warm place in the shade, but not too near a stove or fire. Keep in paper bags, hung in a dry airy place, beyond the reach of mice. Trying the quality of seeds is important, as it may save loss and disappointment, from sowing seeds that will not vegetate. A little cotton wool or moss in a tumbler containing a little water, and placed in a warm room, will afford a good means of testing seeds. Seeds placed on that wool, will vegetate sooner than they would do in the soil. But a more speedy, and generally sure method, is by putting a few seeds on the top of a hot stove. If they are good they will crack like corn in parching; otherwise they will burn without noise, and with very little motion. The improvement or declension of fruits, grains, and vegetables, depend very materially upon the manner of gathering and preserving seeds. Gather promiscuously and late, and keep without care, and rapid declension will be the result. Gather the earliest and best, and plant only the very best of that saved, and constant improvement will be secured. SHEEP.
