compact, and full of marine bodies, like thofe o f the ¡¡aim
communi in the .Vicentine. The high road divides, Monte Cavallo
from. Verbnik; the bottpms o f which, are o f a: coarfo-
grained porous whiritli limeftone, tinged with reddiih ochre.
H a lf way up the hill,, there is ap irregular prominent mafs o f ar>
friable inferior fort o f granite, which feems to extend from its
bowels, I in a direction towards the contiguous hill. The breadth,
o f this mafs above ground is about two hundred feet; the fo-
hdity o f the fubitance is unequal, but always lefs than that o f
our .Raduan granites. I frequently found pieces very much re-
fembling thofe, in .the. hills o f . Galzignanoy- among the fiindyv
oehrpits ilones thrown, out by thofe ancient volcanos.
; Above this, vulcanic matter o f Monte Cavallo, there is a itra-
tum of hard calcareous ftone, and,, aboye that, another.of gravelly.
breccia| at the extremities, is a mixture o f calcareo-marine,.
and vulcanic .matter, The.ealeareo-marinc mafs,. and the lira—
ta 4?^, gTjlvelly Jnjeacia, which are alfo o f the fame nature, arer
much higher than, the vulcanic fubftances;. and if..a little to r -
rgpt,, in cp.urfc of.year«,, had not difcovered them, it would,
fcarcely have been imagined, that the interior parts o f the Verbnik
had fuffered by . fubterraneous fire; for the confufiom and
disjuniftiojt difcerpabb? on, the pqtfi^e,. would, not have fhewn
from whence they were derived, .Thefe,parts are ftil] febje a ¡ g
frequent earthquake^;: and,, probabiy,, were, much more fo, fo.
early times;, it is not eafy to conceive, that, without the moftr
violent agitations,, whole ftrata o f rounded itones, which ltill pof
ftfe a great, part o f the heights, could be torn afunder, and funk ■
and that pew h,Us, o f a fubitance that had undergone the aCtion
o f fire, ihould anfe from that abforption; and fometimes that'
mafles o f ancient gravelly bryccia ihould be raifed among them.
The
The channel o f the river muft have fuffered great changes, and
•one clear indication o f it is, the fteepnefs ând height o f the'
craggy cafcade o f Topolye, from whofe upper edge, i f a line
were drawn,' it would' reach above the tops o f the new hills,
and, fall in with the fide o f Verbnik. Not far diflant from
Monte Cavallo ftood the ancient Liburhian city o f Promona,
which coil the Romans fo much. The coun try round it is
very ragged, and it would require time, and great leifure to
colleCt the remains o f antiquity that are fcattered up and
down. The vefliges o f the wall which Augujius cauled to
be built by his foldiers, for fifty Jladii o f circuit, in order
to cut off the communoation between the Illyrians, who had
fortified themfelves in. Promana and, their allies o f . the neigh-,
bouring territories, are itili to be feenon the tops o f thofe craggy,
mountains. The Kerka paffes between Verbnik,; and the .hill o f
Knin, through a narrow and crooked channel, which retards,
the current muph ; and the ftream of Butimfçhiza falls into it a
little below, which o p c a f i o n s a further impediment, by the quantity
o f fand and,gravel brought along with it, rendering dangerous
the navigation, which is moreover often interrupted on
this river by cafcades.

The Butimfchiza takes its fo-.trce at the foot o f the hill o f
Stermrzza, by the union o f three final! currents,' the largeft o f
which, called C%erni-plok, or thé black torrent; afte* running
nine miles from mount Gelinach, in a winding courfe,
it meets the water -of M-arabai, arifing out o f mount Pliffivfza,
and then after à courfe -of fix miles more, enters, together
