Melt some brimstone, and dip into it a piece of coarse linen cloth; of which, when cold, take a piece of about an inch broad and five inches long, and set fire to it, putting it into the bung-hole, with one end fastened under the bung, which must be driven in very tight: let it remain a few hours before removing it out. _To make Oyster Powder._ Get some fresh oyster-shells, wash them and scrape off the yellow part from the outside; lay them on a clear fire till they become red hot; then lay them to cool, and take off the softest part, powder it, and sift it through a fine sieve; after which use it immediately, or keep it in bottles well corked up, and laid in a dry place. _To make a Filtering Bag._ This bag is made of a yard of either linen or flannel, not too fine or close, and sloping, so as to have the bottom of it run to a point, and the top as broad as the cloth will allow. It must be well sewed up the side, and the upper part of it folded round a wooden hoop, and well fastened to it; then tie the hoop in three or four places with a cord to support it; and when used, put a can or pail under it to receive the liquor, filling the bag with the sediments; after it has ceased to run, wash out the bag in three or four clear waters, then hang it up to dry in an airy place, that it may not get musty. A wine dealer should always have two bags by him, one for red, and the other for white wines. _To bottle Wine._ When wine is made fine and pleasant, it may be bottled, taking care afterwards to pack it in a temperate place with saw-dust or leather. After which it will not be fit to drink for at least two months. Never use new deal saw-dust, as that causes the wine to fret, and often communicates a strong turpentine smell through the corks to the wine. _To Detect Adulterated Wine._ Heat equal parts of oyster-shells and sulphur together, and keep them in a white heat for fifteen minutes, and when cold, mix them with an equal quantity of cream of tartar; put this mixture into a strong bottle with common water to boil for one hour, and then decant into ounce phials, and add 20 drops of muriatic acid to each; this liquor precipitates the least quantity of lead, copper, &c. from wines in a very sensible black precipitate. _To Detect Alum in Wine._
