may more fully and at large appear.
NOW KNOW YE, that in compliance with the said provisoe, I, the said
Thomas Bridge, do hereby declare that our said Invention of a Method of
producing an Essence or Extract of Spruce, so perfect that one Pound and a
Quarter will make Sixty Gallons of fine Spruce Beer, which will be fit to
drink in Three Days in any Climate, is described in the manner following (that
is to say):-
Charge a still of any size with tops or small branches of spruce, then fill it
near the top with water, lute on the head, then with a gradual heat for four
hours draw off near about one half of the quantity of liquor first put in the
still; a separating glass must be placed to the worm for the liquor to run
through, and all the essential oyl on the top of the glass is to be carefully
saved. So soon as half the quantity of liquor is run off, take the head from
the still, and let the residuum run through the cock into a boiler, in which is
also fresh tops or small branches of spruce, then light a fire under the boiler
and begin to evaporate this liquor gradually away, frequently stirring it about.
When all the residuum is run from the still, throw in cold water to prevent it
from burning; then take out all the spruce and fill it again with fresh tops,
then pour on them all the first drawn liquor, and fill up the still with more
water, lute on the head, and draw off as before, and when the proper quantity
is run off through the seperating glass, let the residuum in the still run again
into the boiler with the first; then encrease the fire under it and evaporate the
whole to about two thirds; then let the fire be quite extinguished, and pour
all the decoction into the finishing or extract boiler, under which light a fire,
and with an equal & gradual heat evaporate the decoction into the consistence
of honey or treakle, taking particular care to keep it constantly stirring with
a broad wooden spatula. So soon as it begins to thicken, and when compleated,
let the fire be immediately extinguished, and the extract taken out as quick as
possible into a large open vessel to cool, after which the essential oyl drawn
from the seperating glasses is to be carefully mixed with the extract by
pouring in a little at a time, keeping constantly stirring till both substances
are mutually incorporated together; then your essence or extract will be com-
pleat, then let it be put into a vessell confined from the air.
In witness whereof, I, the said Thomas Bridge, have hereunto set my
hand and seal this Seventh day of December, One thousand seven
hundred and seventy-two.
THOS BRIDGE. (L.B.)
