at a place called Puerto Blanco. The vein does not appear
above ground, but a few feet from the furface there
is a ilratum of extraneous'carth, different frbm the other
earth feen hereabout. In this mine they find virgin fil-
ver, copper pyrites in the quartz, and a little iron.
Two leagues and a half from Cazalla, there is a high
mountain called Fuente cle la Reyna, where the Conftan-
tina mine is to be feen, fo called from a village o f that
name, about two. leagues diftant,. anti not derived from
the Emperor Conftautinc, who never was in Spain, nor
was the founder-of it, according to the ¡popular error
which prevails ¡on that fubjcci. ¡In former times this
mine was worked with great judgment, as appears front
the r ¿mains o f their ihafls and galleries... The vein'runs
front north to fouth acrofs the direclion o f the flate, and
as. the miners term it, has its hat o f iron, with p y rites
and blend o f filver and lead in the fpar. Lower
down they found filver, called by; the: ¡Spanifli miners
Flat'a helada, “ frofted filver”, and a mine;of lead.ip a fmall
teffallated form. Some years agoan inhabitant of Qon-
ftantifla undertook, the; working pf ;this_,mine^ funk, two
ilialts, and made galleries on the top o f the hill, but
abandoned it foon after, perhaps for want o f ikill, of
fufficient capital to go on with the works, though it was
thought*to tdeferve more attention,, as ,fh[e: ore was good,
and they had fuel at hand with a brook af tfic loot of .the

Two leagues to the weftward o f Cazalla, there is a copper
mine, at a place called Canada de Jos Conejos, which
from its appearance ftiomld be rich, the vein running from
north to fouth in a pyritous quartz. Half a league from
Cazalla there is a mine of vitriol, at -a. place ¡called €afta-
nares, from the number 'of chefnutitrees growing there.
The ftone is pyritous and ferruginous with deep effl©-
refcencies, or fppts 'of a gieenilh iyellow, and a kind of
white powder, which is vitriol divefted « f the water that
cryftalifes it.

the -chins, the terebinthus and other plants fimilar to
thofe on other hills in this country,'you come to a
little Village, called E l Real de MowdJler,w.. Half a league
