it, and stir it together with two gallons of cyder more added to it,
and apply to the hogshead; stir it well with your paddle, and shive
it up close. The next day give it vent, and you will find it fine and
bright. If you force perry, cut your isinglass with cyder or stale
beer, for no liquor will force its own body.


To cure ACID CYDER.

It is always to be observ'd, that even weak _alkali_'s cure the
strongest acid, such, for instance, as calcin'd chalk, calcin'd
oyster or scallop-shells, calcin'd egg-shells, alabaster, &c. But if
a hogshead can soon be drank, use a stronger _alkali_, such as salt of
tartar, salt of wormwood; but in using them, you must always preserve
their colour with _lac_, or else the _alkali_ will turn the liquor
black, and keep it foul.

To one hogshead, take two gallons of _lac_, and put to it one ounce
and a half of isinglass beat well and pulled small; boil them together
for five or six minutes; drain it, and when a stiff jelly, break it
with a whisk, and mix about a gallon of the cyder with it; then
put three pounds of calcin'd chalk, and two pounds of calcined
oyster-shells to it, whisk it well together with four gallons more
of the cyder, and apply it to the hogshead. Stir it well, and it will
immediately discharge the acid part out at the bung. Let it stand one
hour, then bung it close for five or six days; rack it from the bottom
into a clean hogshead, and apply one quart of forcing to it. If you
use a strong _alkali_, put to the _lac_ four ounces of salt of tartar,
or salt of wormwood; but the former is best, as it hath not the bitter
taste in it which the wormwood has.
