 leaves of a Shrub, plentiful in Languedock, and gather'd in the end of May, and the beginning of June, full of a red Juyce; subjoynes two Uses, which that Grain hath, the one for Medicine, the other for Dying of Wool. Waving the first, notice shall only be taken here of the latter, vid. That, for Dying, they take the Grain of Kermes, when ripe, and spread it upon Linnen: And at first, whilst it abounds most in moisture, 'tis turn'd twice or thrice a day, to prevent its Heating. And when there appears red powder amongst it, they separate it, passing it through a Searce; and then again spread abroad the Grain upon Linnen, untill there be perceived the same redness of the powder; and at the end, this red powder appears about and on the surface of the Grain, which is still to be pass'd through a Searce, till it render no more.

And in the beginning, when the small red Grains are seen to move (as they will do) they are sprinkled over with strong Vinegar, and rubb'd between on's hands: afterwards, little Balls are form'd thereof, which are expos'd to the Sun to dry.

If this red powder should be let alone, without pouring, Vinegar or some other accid liquor upon it, out of every Grain thereof would be form'd a little Fly, which would skip and fly up and down for a day or two, and at last changing its colour, fall down quite dead, deprived of all the bitterness, the Grains, whence they are generated, had before.

The Grain being altogether emptyed of its pulp or red powder, 'tis wash'd in Wine, and then expos'd to the Sun. Being well dryed, 'tis rubb'd in a Sack to render it bright; and then 'tis put up in small Sacks, putting in the midst, according to the quantity, the Grain has afforded, 10. or 12. pounds (for a Quintal) of the dust, which is the red powder, that came out of it. And accordingly, as the Grain affords more or less of the said powder, Dyers buy more or less of it.

'Tis to be noted, That the first red powder, which appears, issues out of the Hole of the Grain, that is on the side, where the Grain adhered to the Plant. And that, which about the end appears sticking on the Grain, hath been alive in the husk, having pierced its cover; though the hole, whence it commonly issues, remains close as to the Eye. Rh
