Suba and Facatativa, which, rise like islands from the midst of the savannas, all suggest the existence of a former lake-basin. The stream of Funza, commonly called the Rio de Bogotá, has forced a channel for itself through the mountains southwest of Santa Fé It issues from the valley at the estate of Tequendama, falling through a narrow opening into a canon which descends to the valley of the Magdalena. If this opening, the only outlet the valley of Bogotá has, were closed, the fertile plain would gradually be converted into a lake like that of the Mexican plateau."
On this high plain, whose even, mild climate permitted the cultivation of the grains of the temperate zone, lived, in small communities, according to their several dialects, the agricultural village Indians, the Muysca. Isolated by nature, for the highland that girt them on every side could be reached only through narrow ravines, they were entirely surrounded by savage cannibal tribes. Such were the Panches west of Bogota, and in the north the semi-nomadic kindred tribes to the Muysca, the Musos and Colimas.
