near the fea-fide are always the beft, becaufe they acquire a great
deal of fait by their nearnefs to the fea.
Alga is one of them. See ALGA.

Pot-afhes are alfo proper on this account; they are brought
from Poland, Ruffia, and New England ; and are afhes, for the
moft part, of firs and pines, and their apples.

The fait of all forts of afhes may ferve for common (or green)
glafs, notwithftanding that of the afhes of the common thiftle
is the beft; but all forts of thiftles are good.

Next to thiftles, hops are the beft, taking both ftem and
branch when the flowers are gathered.

Among trees the mulberry is the beft (C. M. fays, the bram-
ble-bufh) as alfo genifta fpinofa, and the haw-thorn, and black-
thorn, which bears blackberries, and, among the fea-plants,
kali fpinofum.

So that it feems, that thofe plants which are thorny and
prickly afford in their kind the beft and moft fait.

All rufhes and reeds which grow in marfhes and in pools, and
in ditches of water, and on banks of rivers, yield a great deal of
fait fit for thefe purpofes.

Next to the beforementioned are all bitter herbs, as hops,
wormwood, carduus beneditShis, centaury, gentian, fouthern-
wood, tanfy wood, which they ufe in dying wool; the heads of
poppies, and feveral other plants ; tobacco ftalks, all leguminous
plants, have the fame virtues; bean cods and ftalks yield an ad-
mirable fait for making Cryftal; peafe, vetches, millet, lupine,
and lentils, as alfo cabbage heads, and feveral other foits of
plants.

Add to thefe milky plants all forts of tithymals or fpurges,
cataputium, the fig-tree, vine-branches, and fow-thiftles.

Of all the fixed falts which are extracted from plants, obferve,
that thofe are the beft that are freeft from earth, and all forts of
heterogeneous bodies, and which are united in the hardeft and
whiteft lumps, and are moft fharp to the tafte.

That the beft afhes and fulleft of pure fait run fooneft in the
furnace.

That thofe are the beft afhes of vegetables that are made
while they are green, and of the biggeft branches.

That thofe falts muft be diligently kept in a dry place, re-
mote from any moifture, that may be hurtful to them ; that the
afhes of oak, which partake of a vitriolic nature, make a glafs
of a darker colour; and afh and haw-thorn, their falts being
more nitrous, make the whiter metal.
