La Guaira is more a bay than a harbor; the sea is always rough, and boats are exposed to dangerous winds, sandbanks and mist. Disembarking is very difficult as large waves prevent mules from being taken ashore. The negroes and freed mulattos who carry the goods on to the boats are exceptionally muscular. They wade into the water up to their waists and, surprisingly, are not scared of the sharks that teem in the harbor. The sharks are dangerous and bloodthirsty at the island opposite the coast of Caracas, although they do not attack anybody swimming in the harbor. To explain physical phenomena simply people have always resorted to marvels, insisting that here a bishop had blessed the sharks in the port.

We spent seven agreeable days at the Hacienda de Cura in a small hut surrounded by thickets; the house itself, located in a sugar plantation, was infected with bubos, a skin disease common among slaves in the valleys. We lived like the rich; we bathed twice a day, slept three times and ate three meals in twenty-four hours. The lake water was warm, some 24°C to 25°C. The coolest bathing place was under the shade of ceibas and zamangs at Toma in a stream that rushes Out of the granite Rincòn del Diablo mountains. Entering this bath was fearsome, not because of the insects but because of the little brown hairs covering the pods of the Dolichos pruriens. When these small hairs, called pica pica, stick to your body they cause violent irritations. You feel the sting but cannot see what stung you.

When we carefully examine this wild part of America we imagine how it was in primitive times when the land was peopled in stages, and seem to be present at the birth of human societies. In the New World we do not see the progressive developments of civilization, those moments of rest, those stations in the lives of a people. Such is the wonderful fertility of nature that the Indian's field is a patch of land. To clear it means setting fire to branches. To farm means dropping a few seeds into the ground. However far back in time you go in thought in these dense jungles the Indians have got their food from the earth, but as this earth produces abundantly on a small patch, without much work, these people often change their homes along the river banks. Still today, the Orinoco Indians travel with their seeds, transporting what they cultivate (conucos), like the Arab does his tents.

But the shores of Lake Valencia are not famed solely for their picturesque beauties: the basin presents several phenomena whose interpretation holds great interest for natural historians and for the inhabitants. What causes the lowering of the lake's water-level? Is it receding faster than before? Will the balance between the flowing in and the draining out be restored, or will the fear that the lake might dry up be proved justified?

Our first excursion to the Araya peninsula was followed by another more important and instructive one to the mountain missions of the Chaima Indians. Such a variety of objects attracted our attention. We found ourselves in a country bristling with forests on our way to visit a convent shaded by palm trees and arborescent ferns in a narrow valley which was deliciously fresh, despite being in the middle of the torrid zone. In the surrounding mountains there are eaves inhabited by thousands of nocturnal birds; and, what struck our imagination more than all the marvels of the physical world, even further up we found a people until recently still nomadic, hardly free from a natural, wild state, but not barbarians, made stupid more from ignorance than from long years of being brutalized. What we knew about history increased our interest in these people. The promontory of Paria was what Columbus first saw of this continent; these valleys ended there, devastated first by the warlike, cannibalistic Caribs, then by the mercantile and orderly European nations. If the Spaniards visited these shores it was only to get, either by violence or exchange, slaves, pearls, gold and dye-woods; they tried to dignify their motives for such an insatiable greed with the pretence of religious zeal.

The outlying area of Cumana is as densely populated as the old town. This includes Los Cerritos, where we met with attractive tamarind trees, San Francisco to the south-east, and the place where the Guaiqueri live. The name of this tribe was quite unknown before the conquest. The Indians who use this name used to belong to the Warao who still inhabit the marshy area of the Orinoco delta. Some old men assured me that the language of their ancestors was a Warao dialect, but in Cumana and Margarita not one Indian has spoken anything but Castilian for over a century.

If you compare the Río Negro with the Amazon, the River Plate or the Orinoco it is but a river of the second order. Possessing it has been, for centuries, of great political interest for the Spanish Government because it affords its rivals, the Portuguese, easy access into the Guianan missions to worry the Capitanía-General of Caracas in its southern limits. Three hundred years have passed in pointless territorial disputes. In different times, according to their degree of civilization, people have leaned either on papal authority or on astronomy. As they have generally been keener to prolong this dispute rather than solve it, only nautical science and geography have gained anything. When the affairs of Paraguay and the possession of the Sacramento colony became important for the two Courts of Madrid and Lisbon, commissioners were sent out to study the boundaries of the Orinoco, Amazon and River Plate. Besides the idle, who filled archives with their complaints and lawsuits, there were a few educated engineers and some naval officers acquainted with the means of determining the position of a place. The little we knew up to the of the last century about the geography of the interior of the Continent is due to these hard-working men. It is pleasing to remind ourselves that the sciences gained accidentally from these border commissions, often forgotten by the states that sent them out.
