Air-volcano, or Salce, of Cumacatar, to the south of San Jose and Carupano, near the northern coast of the continent, between La Montana de Paria and the town of Cariaco. Almost constant explosions are felt in a clayey soil, which is affirmed to be impregnated with sulphur. Hot sulphureous waters gush out with such violence that the ground is agitated by very sensible shocks.

Others vaguely allege that it is an air-volcano, and that asphaltic soils, like those of Mena, cause these inflammable exhalations which are so constant in their appearance. The phenomenon is observed on a mountainous and uninhabited spot, on the borders of the Rio Catatumbo, near the junction with the Rio Sulia.
