A Formula for the Manufacture of Artificial Cider.--Imitation cider
consists of 25 gallons soft water, 25 pounds New Orleans sugar; 1 pint
yeast; two pounds tartaric acid. Put all the ingredients into a clean
cask, and stir them up well after standing twenty-four hours with the
bung out. Then bung the cask up tight, add 3 gallons spirits, and let it
stand forty-eight hours, after which time it will be ready for use.
Champagne cider can be prepared by taking 10 gallons of cider, old and
clear. Put this in a strong, iron-bound cask pitched inside (like beer
casks); add 2-1/2 pints clarified white plain syrup; then dissolve in it
5 ounces tartaric acid; keep the bung ready in hand, then add 7-1/2
ounces of potassium bicarbonate; bung it as quickly and as well as
possible.

Recipe for Making Instantaneous Ink and Stain Extractor.--Take of
chloride of lime 1 pound, thoroughly pulverized, and 4 quarts
soft water. The foregoing must be thoroughly shaken when first put
together. It is required to stand twenty-four hours to dissolve the
chloride of lime; then strain through a cotton cloth, after which add
a teaspoonful of acetic acid to every ounce of the chloride of lime
water.

Wood, which is a more unyielding material, acts with tremendous force
when wetted, and advantage has been taken of this fact in splitting
blocks of granite. This process is largely adopted in Dartmoor. After a
mass of granite has been rent from the mountain by blasting, it is
measured in every direction to see how best to divide it into smaller
blocks. These are traced out by straight lines on the surface, and a
series of holes are drilled at short intervals along this line. Wedges
of dry wood are then tightly driven into the holes and wetted, and the
combined action of the swelling wood splits the block in the direction
required, and without any destructive violence. The same process is then
carried out upon the other faces, and the roughly-shapen block finished
with the hammer and chisel.

The Weight and Value of a Cubic Foot of
Solid Gold or Silver.--A cubic foot of gold weighs about 19,300 ounces,
and gold is worth $20.67 per ounce. Silver is worth $1.29 per ounce, and
a cubic foot weighs 10,500 ounces. Consequently the cubic foot of gold
