BLAMANGE. Boil two ounces of isinglass half an hour, in a pint and half of water, and strain off the cream. Sweeten it, and add some peach water, or a few bitter almonds; let it boil up once, and put it into what forms you please. Be sure to let the blamange settle before you turn it into the forms, or the blacks will remain at the bottom of them, and be on the top of the blamange when taken out of the moulds. If not to be very stiff, a little less isinglass will do.--For Yellow Blamange, pour a pint of boiling water upon an ounce of isinglass, and the peel of one lemon. When cold, sweeten with two ounces of fine sugar: add a quarter of a pint of white wine, the yolks of four eggs, and the juice of one lemon. Stir all together, and let it boil five minutes: strain through a bag, and put into cups. BLANKETS, if not in constant use, are liable to be moth-eaten. To prevent this, they should be folded and laid under feather beds that are in use, and occasionally shaken. When soiled, they should be washed, not scoured: and well dried before they are laid by, or they will breed moths. BLEACHING OF STRAW. This is generally done by the fumes of sulphur, in a place enclosed for that purpose: but to render the straw very white, and encrease its flexibility in platting, it should be dipped in a solution of oxygenated muriatic acid, saturated with potash. Oxygenated muriate of lime will also answer the purpose. To repair straw bonnets, they must be carefully ripped to pieces; the plat should be bleached with the above solution, and made up afresh. BLUE INK. Dissolve an ounce of finely powdered verdigris, and half an ounce of cream of tartar, in three ounces of water. This will make a fine blue writing ink, which has the singular property of giving to an iron nail, immersed in it for twenty-four hours, a beautiful green colour. BOARDED FLOORS will preserve a beautiful appearance, if treated in the following manner. After washing them very clean with soda and warm water, and a brush, wash them with a large sponge and clean water, observing that no spot be left untouched. Be careful to clean straight up and down, not crossing from board to board: then dry with clean cloths, rubbing hard up and down the same way. The floors should not be often wetted, but very thoroughly when done; and once a week dry-rubbed with hot sand, and a heavy brush, the right way of the boards. If oil or grease have stained the floor, make a strong lye of pearl-ashes and soft water, and add as much unslaked lime as it will take up. Stir it together, and then let it settle a few minutes; bottle it, and stop it close. When used, lower it with a little water, and scour the part with it. If the liquor lie long on the boards, it will extract their colour; it must therefore be done with care and expedition. Stone work may be freed from stains in the same way.
