our, and expose it to the
night air to purify. Tin makes the best yeast vessel for yeast made
daily, in the above mode.

In the course of my long practice in distilling I fully discovered that
a nice attention to yeast is absolutely necessary, and altho' I have in
the foregoing pages said a great deal on the subject, yet from the
importance justly to be attached to this ingredient in distilling, and
to shew more fully the advantages and disadvantages arising from the use
of good and bad yeast, I submit the following statement for the
consideration of my readers.

Advantages in using good yeast for one month,
at 5 bushels per day; 30 days at 5 bushels,
is 150 bushels at 60 cents, costs $ 90 00

Contra
150 bushels yield 3 gallons per bushel, at
50 cents per gallon--450 gallons,
225 00
--------
Profit $ 135 00

Disadvantages sustained during the above period.
150 bushels at 60 cents, $ 90 00

Contra
150 bushes yielding 1-1/2 gallons to the
bushel--225 gallons at 50 cents, 112 50
-------
Profit $ 21 50

Thus the owner or distiller frequently sustains in the distillation of
his produce, a loss, equal and in proportion to the foregoing--from the
use of indifferent yeast, and often without knowing to what cause to
attribute it. This statement will shew more forcibly, than any other
mode--and is made very moderate on the side of indifferent yeast, for
with bad sour yeast the yield will be oftener under one gallon to the
bushel than above one and an half--whereas with good yeast the yield
will rarely be so low as three gallons to the bushel. It is therefore, I
endeavor so strongly to persuade the distiller to pay every possible
attention to the foregoing instructions, and the constant use of good
yeast only, to the total rejection of all which may be of doubtful
quality.

_Observations on Wood for Hogsheads._

The cheapest and easiest wrought wood is generally most used for making
mashing tubs, or hogsheads, and very often for dispatch or from
necessity, any wood that is most convenient is taken, as pine or
chesnut; indeed I have seen poplar tubs in use for mashing, which is
very wrong, as a distiller by not having his
