We arrived on the 15th of July at the Fundacion, or Villa, del Pao, founded in 1744, and situated very favourably for a commercial station between Nueva Barcelona and Angostura. Its real name is El Concepcion del Pao. Alcedo, La Cruz, Olmedilla, and many other geographers, have mistaken the situation of this small town of the Llanos of Barcelona, confounding it either with San Juan Bauptisto del Pao of the Llanos of Caracas, or with El Valle del Pao de Zarate. Though the weather was cloudy I succeeded in obtaining some heights of alpha Centauri, serving to determine the latitude of the place; which is 8 degrees 37 minutes 57 seconds. Some altitudes of the sun gave me 67 degrees 8 minutes 12 seconds for the longitude, supposing Angostura to be 66 degrees 15 minutes 21 seconds. The astronomical determinations of Calabozo and Concepcion del Pao are very important to the geography of this country, where, in the midst of savannahs, fixed points are altogether wanting. Some fruit-trees grow in the vicinity of Pao: they are rarely seen in the Llanos. We even found some cocoa-trees, which appeared very vigorous, notwithstanding the great distance of the sea. I was the more struck with this fact because doubts have recently been started respecting the veracity of travellers, who assert that they have seen the cocoa-tree, which is a palm of the shore, at Timbuctoo, in the centre of Africa. We several times saw cocoa-trees amid the cultivated spots on the banks of the Rio Magdalena, more than a hundred leagues from the coast.
