[15.] To keep Vegetables and Herbs.
Succulent vegetables, are preserved best in a cool shady place that is damp. Turnips, potatoes, and similar vegetables should be protected from the air and frost, by being buried in earth; in very severe cold weather, they should be covered with a linen cloth. It is said that the dust of charcoal will keep potatoes from sprouting, if sprinkled over them.—Herbs should be gathered on a dry day, either just before or while in blossom; they should be tied in bundles and hung in a shady airy place, with the blossoms downwards. When perfectly dry, put away the medicinal ones in bundles; pick off the leaves of those that are to be used in cooking, pound and sift them, and keep them in bottles corked tight.
[16.] To preserve various kinds of Fruit over winter.
Apples can be kept till June, by taking only those that are perfectly sound, and wiping them dry, and putting them in barrels with a layer of bran to each layer of apples. Cover the barrel with a linen cloth to protect them from the frost. Mortar put on the top of the apples, is said to be an excellent thing to prevent their decaying, as it draws the air from them, which is the principal cause of decay; the mortar should not touch the apples. To preserve oranges and lemons for several months, take those that are perfectly fresh, and wrap each one by itself in soft paper, and put them in glass jars, or a very tight box, strew white sand thickly round each one and over the top. The sand should be previously perfectly dried in the oven, several hours after baking in it. Cover the fruit up tight, and keep it in a cool dry place, but not so cold as to freeze it. To preserve grapes gather them on a dry day, when not quite dead ripe; pick those off from the stem, that are not perfectly fair, lay them in a glass jar and on each layer sprinkle a layer of dry bran, taking care that none of the grapes touch each other, have a layer of bran on the top of them, and cork and seal them tight. A box will do to keep them in if covered with mortar. To restore them to their freshness when they are to be eaten, cut the ends of the stalks and immerse them in wine, let them remain in it for a few moments before they are to be eaten. Various kinds of green fruit, such as grapes, currants, gooseberries and plums, can be kept the year round by putting them in bottles, and setting them in an oven four or five hours after baking in it; let them remain in it till they begin to shrink, then cork and seal them tight, they will be fit for pies, whenever you wish to use them. Ripe blackberries, and whortleberries, dried perfectly in the sun, and tied up in bags so as to exclude the air, will keep good over the winter. Whenever you wish to use them for pies, pour on boiling water enough to cover them, and let them remain in it till they swell to nearly the original size, then drain off the water, and use them.
[17.] To extract essences from various kinds of flowers.
Procure a quantity of the petals of any kind of flowers that have an agreeable fragrance. Card thin layers of cotton, which dip into the finest Florence oil. Sprinkle a small quantity of salt on the flowers, and put a layer of them in a glass jar or wide mouthed bottle, with a layer of the cotton, put in a layer of each alternately until the jar is full, then cover the top up tight with a bladder. Place the vessel in a south window, exposed to the heat of the sun. In the course of a fortnight, a fragrant oil may be squeezed from the cotton, little inferior if rose leaves are made use of, to the imported otto of rose.
[18.] Indelible Ink for marking linen.
Dissolve a drachm of lunar caustic, in half an ounce of pure cold water. Dip whatever is to be marked in pearlash water, dry it perfectly, then rub it smooth with a silver spoon, (ironing it sets the pearlash water,) write on it, and place it in the sun, and let it remain until the name appears plain and black. Red ink for marking linen, is made by mixing and reducing to a fine powder, half an ounce of vermilion, a drachm of the salt of steel, and linseed oil enough to render it of the consistency of black durable ink.
