This Rage For The
Search Of Mines Strikes Us The More In A Climate Where The Ground
Needs Only To Be Slightly Raked To Produce Abundant Harvests.
After visiting the pyritous marls of the Rio Juagua, we continued
following the course of the crevice, which stretches along like a
narrow canal overshadowed by very lofty trees.
We observed strata
on the left bank, opposite Cerro del Cuchivano, singularly crooked
and twisted. This phenomenon I had often admired at the Ochsenberg,
* in passing the lake of Lucerne. (* This mountain of Switzerland
is composed of transition limestone. We find these same inflexions
in the strata near Bonneville, at Nante d'Arpenas in Savoy, and in
the valley of Estaubee in the Pyrenees. Another transition rock,
the grauwakke of the Germans (very near the English killas),
exhibits the same phenomenon in Scotland.) The calcareous beds of
the Cuchivano and the neighbouring mountains keep pretty regularly
the direction of north-north-east and south-south-west. Their
inclination is sometimes north and sometimes south; most commonly
they seem to take a direction towards the valley of Cumanacoa; and
it cannot be doubted that the valley has an influence* on the
inclination of the strata. (* The same observation may apply to the
lake of Gemunden in Styria, which I visited with M. von Buch, and
which is one of the most picturesque situations in Europe.)
We had suffered great fatigue, and were quite drenched by
frequently crossing the torrent, when we reached the caverns of the
Cuchivano.
