It is stated that a bushel of peanuts (twenty-two pounds in the hull) subjected to the hydraulic press, will yield one gallon of oil. The yield by cold pressure, is from forty to fifty per cent. of the shelled kernels, though if heat be used, a larger quantity of oil, but of inferior quality, is obtained. The best Peanut oil is nearly colorless, with a faint, agreeable odor, and a bland taste, resembling that of olive oil. It is more limpid than olive oil, and becomes thick when exposed to a temperature a few degrees below the freezing point of water. Peanut oil is not one of the drying oils. During the late war it was extensively employed in the Southern machine shops, and regarded as superior in its lubricating qualities to whale oil. For burning it is highly esteemed. The chief consumption of the oil is in making soap. For the production of oil for soap making, there were imported into Marseilles, France, from the West Coast of Africa, in one year, peanuts to the value of over five millions of dollars. The residuum, or oil cake, may be sold for cattle feed. =Roasted Peanuts.=--Almost every person residing in the eastern section of our country, must necessarily know something of the value of roasted peanuts. One cannot pass along the streets of any of our larger cities and towns, without encountering, at every turn, the little peanut stands, where roasted peanuts are sold by the pint. They are kept for sale in numerous shops, they are peddled on the railroad cars, and sold to the loungers at every depot. Roasted peanuts are more common than roasted chestnuts once were, and almost everybody eats them. Even the ladies are fond of them, and frequently have them at their parties. It is safe then to say, that everybody likes them, and finds them palatable, healthful, and fattening. From a pig to a school boy, no diet will fatten sooner than roasted peanuts. A person can live on them alone for an indefinite period, if eaten regularly and with moderation. The analysis of the Peanut shows it to be rich in the albuminoids, or flesh-forming elements. Roasted peanuts, therefore, form a very useful article of diet, and fill a place between the luxuries and the necessaries of common life. Wherever they have been once introduced, they cannot well be dispensed with; and as their use in this respect is constantly extending, this purpose alone would serve to keep the product before the public as a salable article. Once let the Peanut find its way to the great cities of Europe, and roasted peanuts be sold upon the streets there, as well as here, and the demand for them will far exceed the present limits, and the cultivation be necessarily extended over a much wider area than now. There is every reason to believe that the demand for the crop will continue to increase.
