The Little Village Is Situated In One Of Those Plains
Covered With Grass That Separate All The Links Of The Granitic
Mountains, From Encaramada To Beyond The Cataracts Of Maypures.
The
line of the forests is seen only in the distance.
The horizon is
everywhere bounded by mountains, partly wooded and of a dark tint,
partly bare, with rocky summits gilded by the beams of the setting
sun. What gives a peculiar character to the scenery of this country
are banks of rock (laxas) nearly destitute of vegetation, and often
more than eight hundred feet in circumference, yet scarcely rising a
few inches above the surrounding savannahs. They now make a part of
the plain. We ask ourselves with surprise, whether some extraordinary
revolutions may have carried away the earth and plants; or whether the
granite nucleus of our planet shows itself bare, because the germs of
life are not yet developed on all its points. The same phenomenon
seems to be found also in the desert of Shamo, which separates
Mongolia from China. Those banks of solitary rock in the desert are
called tsy. I think they would be real table-lands, if the surrounding
plains were stripped of the sand and mould that cover them, and which
the waters have accumulated in the lowest places. On these stony flats
of Carichana we observed with interest the rising vegetation in the
different degrees of its development. We there found lichens cleaving
the rock, and collected in crusts more or less thick; little portions
of sand nourishing succulent plants; and lastly layers of black mould
deposited in the hollows, formed from the decay of roots and leaves,
and shaded by tufts of evergreen shrubs.
