cultivated neighbouring valleys is beautiful, and their aspect is
wonderful after sunset, when thousands of aquatic birds, herons,
flamingoes, and wild ducks cross the lake to roost in the islands, and
the broad zone of mountains which surrounds the horizon is covered
with fire. The inhabitants, as we have already mentioned, burn the
meadows in order to produce fresher and finer grass. Gramineous plants
abound, especially at the summit of the chain; and those vast
conflagrations extend sometimes the length of a thousand toises, and
appear like streams of lava overflowing the ridge of the mountains.
When reposing on the banks of the lake to enjoy the soft freshness of
the air in one of those beautiful evenings peculiar to the tropics, it
is delightful to contemplate in the waves as they beat the shore, the
reflection of the red fires that illumine the horizon.

Among the plants which grow on the rocky islands of the lake of
Valencia, many have been believed to be peculiar to those spots,
because till now they have not been discovered elsewhere. Such are the
papaw-trees of the lake; and the tomato* of the island of Cura. (* The
tomatoes are cultivated, as well as the papaw-tree of the lake, in the
Botanical Garden of Berlin, to which I had sent some seeds.) The
latter differs from our Solanum lycopersicum; the fruit is round and
small, but has a fine flavour; it is now cultivated at La Victoria, at
Nueva Valencia, and everywhere in the valleys of Aragua. The
papaw-tree of the lake (papaya de la laguna) abounds also in the
island of Cura and at Cabo Blanco; its trunk shoots higher than that
of the common papaw (Carica papaya), but its fruit is only half as
large, perfectly spherical, without projecting ribs, and four or five
inches in diameter. When cut open it is found quite filled with seeds,
and without those hollow places which occur constantly in the common
papaw. The taste of this fruit, of which I have often eaten, is
