They Missed Their Way, However; And This Last Descent,
The Steepest Of All, Brought Us Near The Ravine Of Chacaito.
The
noise of the cascades gave this nocturnal scene a grand and wild
character.
We passed the night at the foot of the Silla. Our friends at
Caracas had been able to distinguish us with glasses on the summit
of the eastern peak. They felt interested in hearing the account of
our expedition, but they were not satisfied with the result of our
measurement, which did not assign to the Silla even the elevation
of the highest summit of the Pyrenees.* (* It was formerly believed
that the height of the Silla of Caracas scarcely differed from that
of the peak of Teneriffe.) One cannot blame the national feeling
which suggests exaggerated ideas of the monuments of nature, in a
country in which the monuments of art are nothing; nor can we
wonder that the inhabitants of Quito and Riobamba, who have prided
themselves for ages on the height of Chimborazo, mistrust those
measurements which elevate the mountains of Himalaya above all the
colossal Cordilleras?
During our journey to the Silla, and in all our excursions in the
valley of Caracas, we were very attentive to the lodes and
indications of ore which we found in the strata of gneiss. No
regular diggings having been made, we could only examine the
fissures, the ravines, and the land-slips occasioned by torrents in
the rainy season. The rock of gneiss, passing sometimes into a
granite of new formation, sometimes into mica-slate,* (* Especially
at great elevations.) belongs in Germany to the most metalliferous
rocks; but in the New Continent, the gneiss has not hitherto been
remarked as very rich in ores worth working. The most celebrated
mines of Mexico and Peru are found in the primitive and transition
schists, in the trap-porphyries, the grauwakke, and the alpine
limestones. In several spots of the valley of Caracas, the gneiss
contains a small quantity of gold, disseminated in small veins of
quartz, sulphuretted silver, azure copper-ore, and galena; but it
is doubtful whether these different metalliferous substances are
not too poor to encourage any attempt at working them. Such
attempts were, however, made at the conquest of the province, about
the middle of the sixteenth century.
From the promontory of Paria to beyond cape Vela, the early
navigators had seen gold ornaments and gold dust, in the possession
of the inhabitants of the coast. They penetrated into the interior
of the country, to discover whence the precious metal came; and
though the information obtained in the province of Coro, and the
markets of Curiana and Cauchieto,* (* The Spaniards found, in 1500,
in the country of Curiana (now Coro), little birds, frogs, and
other ornaments made of gold. Those who had cast these figures
lived at Cauchieto, a place nearer the Rio de la Hacha. I have seen
ornaments resembling those described by Peter Martyr of Anghiera
(which indicate tolerable skill in goldsmiths' work), among the
remains of the ancient inhabitants of Cundinamarca.
