SALAD OIL.—The best is the oil of the OLIVE, which, when pure, is of pale, greenish yellow tint, with an agreeable odor and taste. Refined COTTONSEED OIL has naturally a more reddish tint. It is extensively sold as olive oil or mixed with it, although many grocers keep the genuine olive oil. SALAD DRESSINGS are also in market, some of which are very fine and delicate. Sauces. These articles give zest to food and stimulate digestion. Their composition is very varied and embraces many fruits and vegetables, as the tomato, walnut, garlic, shallot; many herbs, as tarragon, chervill, mint, thyme, marjoram; many condiments, as cayenne, black pepper, mustard, and all the spices; many fish, as lobsters, oysters, clams, shrimp, anchovies; the juices of meat, besides salt, sugar, molasses, etc. PEPPER SAUCE is made from the little Jamaica peppers, the Mexican, Chili pepper, or some other variety of red or green pepper. There are numerous brands, and nearly all are good. The TABASCO PEPPER SAUCE is excellent. TOMATO CATSUP OR KETCHUP is a very wholesome and agreeable addition to the diet. Among the best and most popular varieties is the “SHREWSBURY” TOMATO KETCHUP. Mushroom and Walnut Catsups are less used, but still have many friends. Among the dainty and well known SAUCES, are the WORCESTERSHIRE, LEICESTERSHIRE, GLOUCESTERSHIRE, SULTANA, PICCADILLY, CHUTNEE, SOHO, HARVEY, NORTH OF ENGLAND, etc. There are also various American sauces, some of which are imitations of the above or very similar in composition and flavor. Some of the English sauces are put up in elegant and artistic vases. DOMESTIC FRUITS AND BERRIES. The increasing excellence, abundance and cheapness of fruits and berries is full of promise for the health and vigor of the American people. They are wholesome, cooling and nutritious. APPLES.—This noble fruit is in market the year round; new Southern apples are first marketed in April. APRICOTS are a fine small fruit which ripens in July. CHERRIES reach us from the South in May. NECTARINES come in August. PEACHES are at the height of their season in August and September. Early in the latter month they should be secured for preserving. PEARS.—The choicest are the Dutchess, Bartlett and Virgalieu. CALIFORNIA PEARS are excellent and widely sold through the country. PLUMS ripen in August, and are in season until October. QUINCE is a highly flavored fruit, used only for preserves. GRAPES.—Besides our own abundant and delicious Muscat, Concord, Isabella, Catawba, and other varieties, three-quarters of a million barrels of the hardy and cooling white Almeria grapes are annually imported at New York. They were formerly a costly luxury, but are now abundant and cheap, and will keep through the winter.
