end j but, upon fome trials being made, that may alfo ba

Let the flowers be gathered about the beginning t>f June, or
in July or Auguft, and fome may be found in May ; but the
preparation of the colour by picking out the middle deep Blue
flower-leaves, and prefnng out the juice, muff, be prefied out
with all the expedition pofhble, or they will lofe their perfections.
It is very probable, that, if the chives of thefe Blue cornbottle-
flowers were cured in the fame manner as faffron is, they would
produce a much greater body of colour, from which a tincture
might be drawn with more eafe, than if preffed raw or frefh
from the field. In order to do this, fuch a kiln fhculd be pre-
pared as is ufed for curins; fafTron, in which may be made a fmall
charcoal-fire, which will communicate an heat to the top of
the kiln, which is to be covered with an hair-cloth ; upon
which fhould be laid four or five meets of white paper, fuch as
is ufed in curing of fafFron ; then a parcel of picked flowers are
to be bid on to the thicknefs of two or three inches, laying
clofc and flat with a knife, and fprinkling with fome thin
gum water; then the cake of flowers is to be covered with two
or three more fhcets of paper, and a board with a fmall weight
laid on for a few minutes ; after which the board is to be taken
off, and the cake of flowers to be turned upon the kiln, taking
hold of al! the papers with both hands; and, when it has been
rightly placed, take off the upper papers, and fprinkle the cake
again with fome thin gum water ; and then, fettling the cake of
{lowers again with a knife, let the papers be laid on again with
the board and weight for a minute or two, and then let the
papers be turned again and again, till the cake of flowers be^
comes united, and of the thicknefs of a cake of fafTron. You
will find the flowers to grow darker and darker every time they
are turned, rill at length the cake will look of a deep Blue tend-
ing to a b! ick. From whence a tincture may be eafily drawn.
During this operation, great care muff be taken that the fire
does not fcorch the flowers ; but that it be as conftant and
gentle as poflible, which will be a fure way to bring the flower-
cake to a good colour.
If it mould be objected, that it will be troublefome to make
this Blue colour; let it be confidered what pains and nicety
thtre is in gathering and curing of faffron, which is fometimcs
fold at thirty millings per pound, and feldom comes to three
pounds per pound. But this Blue, if it comes up to the co-
Jour of ukiamarine, will be worth four or five pounds per
ounce, efpecially when it flains fo well as this does.—It would
therefore, in all probability, be worth the while to have a piece
of ground on purpofe for this life, where nothing elfe but this
