To the north-west of Lake Maracaybo, is a vein, or mine of mineral pitch, (used by mixing it with grease, to grave vessels,) which is of such an inflammable nature, that during the hot weather, and particularly at night, corruscations are seen arising from its surface, which have the appearance of quickly repeated lightnings. The Indians and Spaniards, who navigate the vessels and canoes of the lake, called them St. Antony's Lanthorns, or the Lanthorns of Maracaybo, as they serve them to steer by during the dark nights, so prevalent in the torrid zone. The lake of _Valencia_, which though not so extensive as the last we have described, is far more beautiful and useful. Its banks are fertile and healthy, and clothed with the most luxurious vegetation. It is situated three miles from the city of Valencia, and eighteen from the sea, from which it is separated by inaccessible mountains; the lake of Valencia is of an oblong form, stretching north-east and south-west, and is forty miles in length and twelve in breadth, in a valley surrounded by very high and steep land, excepting on the west. This extraordinary lake receives the waters of twenty rivers, and has no visible outlet. It has been diminishing for twenty years, and its waters are still receding, leaving behind them a rich and productive soil, but at the same time an unhealthy air; and the cultivators are in some parts under the necessity, from the want of water, of drawing off the neighbouring streams to irrigate their plantations. The eastern side is laid out in tobacco grounds, which occupy 15,000 people, who are paid by the crown; and the islands in which it abounds are highly fertile, the largest called Caratapona, being well populated. The woods near this lake are famous for the diversity and beauty of the birds, and its waters furnish fish, and the guanas, or edible lizard, which are considered as a very delicious food; of these, two species are common to the lake. The water of Lake Valencia is not so good for drinking as that of Maracaybo, being thick and nauseous. This lake bears the Indian name of Tacarigua, as does a bay or lake on the coast, which is situated a league and a half from the mouth of the river Tuy, of a circular form, and is twenty-one miles in length from the sea on the north-east to the south-east, it abounds in fish, and is remarkable for the great number of alligators it contains. The lake of _Parina_, or _Paranapitinca_, in Guiana is said to be an oblong sheet of water, 100 miles in length, and 50 broad, in an island of which is a rock of glittering mica, celebrated as having been the seat of El Dorado, a supposititious city, the streets of which were paved with gold, alluded to by Milton in his Paradise Lost. "And yet unspoil'd Guiana Whose great city Geryon's sons Call El Dorado." This lake is in 3° 40' north latitude, and 45° 20' west longitude, and gives birth to a large river, called Rio Blanco, or Parima, which we have before spoken of.
