dry you can see no mark at all, then hold it to a strong heat and
the writing becomes as black as jet. If you want to write to a young
lady or gentleman, as the case may be, and fearing that the letter
might be opened before she or he gets it, write with common black
ink something of no importance, then between the lines write what
you want to say with the secret ink. The person to whom you are
writing must understand the scheme so that she or he may hold it
to the heat and thereby make the writing visible.


48. CIDER WITHOUT APPLES

To each gallon of cold water put 1 lb. common sugar, 1/2 ounce of
tartaric acid, one tablespoonful of yeast, shake well, make in an
evening and it will be fit for use next day. I make in a keg a few
gallons at a time, leaving a few quarts to make into next time, not
using yeast again until the keg needs rinsing. If it gets a little
sour, make a little more into it or put as much water with it as
there is cider and put it with the vinegar. If it is desired to
bottle this cider by manufacturers of small drinks, you will proceed
as follows: put in a barrel 5 gallons of hot water, 30 lbs. of brown
sugar, 3/4 lb. of tartaric acid, 25 gallons of cold water, 3 pints
of hop or brewer's yeast, work into paste with 3/4 lb. of flower,
and one pint water will be required in making this paste; put all
together in a barrel which it will fill and let it work 24 hours,
the yeast running out at the bung all the time by putting in a
little occasionally to keep it full; then bottle, putting in two
or three broken raisins to each bottle, and it will nearly equal
champagne.
