when fumigating conservatories. The sulphurous acid formed by burning brimstone is a powerful purifier, and will not leave an unpleasant taste, being easily washed away. (4) Cider casks.--Half fill each cask with boiling water, and add ¼ lb. of pearlash, then bung it up, and turn over occasionally for 2 days, then empty, and wash with boiling water. (5) Scald out with boiling water; if the heads are out, put them over a straw fire for a few minutes, so as to slightly char the inside. If you have a steam boiler, partially fill with water, and admit steam through the bung-hole by a pipe down into the water, and so boil. (6) Vinegar casks.--Old vinegar barrels become impregnated to such an extent with acetous substances that it is next to impossible to render them fit for the storage of any other liquid. Fill the barrels with milk of lime, and let this remain in them for several months, then rinse out well with plenty of warm water, and steam them inside for ½ hour. _Cleaning Bottles._--(1) The commonest plan is by means of water and small shot. But lead shot, where so used, often leaves lead carbonate on the internal surface, and this is apt to be dissolved in the wine and other liquids afterwards introduced, with poisonous results; and particles of the shot are sometimes inadvertently left in the bottle. Fordos states that clippings of iron wire are a better means of rinsing. They are easily had, and the cleaning is rapid and complete. The iron is attacked by the oxygen of the air, but the ferruginous compound does not attach to the side of the bottle, and is easily removed in washing. Besides, a little oxidised iron is not injurious to health. Fordos found that the small traces of iron left had no apparent effect on the colour of red wines; it had on white wines, but very little; but he thinks it might be better to use clippings of tin for the latter. (2) Take a handful of common quicklime, such as bricklayers use, and a handful of common washing soda; boil them in a large kitchen iron saucepan (which will only be cleaned, not damaged, by the process). When cold, the fluid will be lye; put this into the vessel you want to clean with some small pebbles; make it warm if you can, and shake up or let it soak according to the nature of the vessel. (3) Gypsum, free from silicate, marble, or bruised bones, is preferable to shot or sand. Sulphuric acid and bichromate mixed, are best to free porcelain and glass from organic matter. _Drying Bottles._--After washing, bottles and decanters should be thoroughly dried inside. Let them first drain completely, then warm them slightly and blow in fresh air by means of a pair of bellows; this will absorb the moisture and leave the interior quite dry.
