To 1 gallon of 95 per cent. alcohol, add 1 quart of camphene oil; mix and shake well, and if transparent it is fit for use, if not, add sufficient alcohol, shaking it well, to bring it to the natural colour of the alcohol. It may be coloured to suit the fancy by adding a little tincture of golden seal, or any other colouring drug. This receipt has been sold for $10. 28. BURNING FLUID Take 4 quarts alcohol, and 1 quart spirits of turpentine; mix well together, and it is ready for use. 29. NON-EXPLOSIVE BURNING FLUID Take 1 gallon 44 proof alcohol, 1 quart camphene, 3 oz. of alum pulverized, 1/2 oz. camphor gum, 65 drops cuicuma; mix all together and let it stand 12 hours, and it is ready for use. 30. VINEGAR IN THREE DAYS WITHOUT DRUGS Take 2 barrels and saw one of them in two in the centre, and put one-half on the top, and the other at the bottom of the whole barrel, (or you may use three whole barrels if you like.) The middle barrel is to be filled with maple, beech, of baswood shavings, which are to be planed from the edge of boards only two or three feet long, which allows the shavings to roll, and prevents them from packing tight, and also allows air to circulate through them, which is admitted through a number of inch holes, which are to be made near the bottom of the barrel and just above the faucet, which lets the vinegar run into the tub below. The top tub has its bottom pierced with small bit holes, having several threads of twine hanging in them to conduct the vinegar evenly over the top of the shavings in the middle of the barrel. Air must be permitted to pass out between the top tub and barrel, which comes in at the holes in the bottom. The shavings which fill the barrel must be soaked three or four days in good vinegar before they are put in. When thus arranged, for every gallon of water use 1/2 lb. of sugar; (that you get from molasses barrels does vary well.) If you wish to make vinegar from whiskey, put in 4 gallons of water to 1 gallon of whiskey; and if from cider, put in one-third water, and fill the top tub with this fluid, putting 1 pint good yeast to each barrel making; and have the holes with threads or twine so arranged that it will run through every twelve hours; and dip or pump up with a wooden pump every night or morning, and three days will make good substantial vinegar, which will keep and also improve by age. Some use only 1 gallon of whiskey to 7 gallons of water. This accounts for so much poor vinegar. Make good vinegar, it will pay you. If a few gallons of water is made boiling hot so as to warm the whole of a gentle warmth, it will make faster than if used cold. This must be done in cool weather, and the room also should be kept warm. For families, small kegs will do, but for manufacturers large casks are best. Many make vinegar by just putting fluid into the barrels of shavings, soaked as directed above, and do not let it run through, but let it stand in the shavings till sour; but it does not work
