Our guides led us to the 'mine'. We turned west, and finally reached the Quebrada de Oro. On the hillside there was hardly a trace of a quartz seam. The landslide, caused by rain, had so transformed the ground that we could not even think of exploring it. Huge trees now grew where twenty years before gold seekers had worked. It is likely that there are veins in the mica-slate containing this venerable metal, but how could I judge if it was worth exploiting or if the metal was to be found in nodules? To compensate our efforts, we set to botanizing in the thick wood around the Hato.

The Indians of this area have preserved the belief that 'during the great flood, when their ancestors had to take to the canoes to escape, the sea waves beat against the Encaramada rocks'. This tradition is found in nearly all the tribes of the Upper Orinoco. When the Tamanacu are asked how the human race survived that great catastrophe they answer: 'A man and a woman saved themselves on a high mountain called Tamanacu and there threw seed from the mauritia palm over their heads, and little men and women were born from the seeds who repopulated the world. Among wild tribes we find a simple version of a legend that the Greeks had embellished with their great imagination! A few leagues from Encaramada a rock called Tepu-mereme (Painted Rock) rises in the middle of the savannah. It is covered with animal drawings and symbolic signs. The representations that we have found on rocks in uninhabited places - stars, suns, jaguars, crocodiles - do not seem to be related to religious cults. These hieroglyphic figures are frequently carved so high up that only scaffolding could reach them. When we asked the Indians how they could have carved those images, they answered, smiling, as if only whites could ignore such an obvious answer: During the great waters, their ancestors reached those rocks in their canoes.

The amount of identical species in the two continents and in the two hemispheres is far less than early travelers once led us to think. The high mountains of equinoctial America have their plantains, valerians, arenarias, ranunculuses, medlars, oaks and pines, which from their features we could confuse with European ones, but they are all specifically different. When nature does not present the same species, she repeats the same genera. Neighboring species are often found at enormous distances from each other, in low regions of a temperate zone, and on mountains on the equator. And, as we found on La Silla at Caracas, they are not the European genera that have colonized mountains of the torrid zone, but genera of the same tribe, which have taken their place and are hard to distinguish

The electrometer gave no sign of electricity. As the storm gathered the blue of the sky changed to grey. The thermometer rose 3'C, as is usual in the Tropics, and a heavy rain fell. Being sufficiently adapted to the climate not to fear the effect of a tropical downpour we stayed on the shore to observe the electrometer. I held it more than twenty minutes in my hand, 6 feet above the ground. For several minutes the electric charge remained the same, and then I noticed that the electricity in the atmosphere was first positive, then nil, then negative. I have gone into these details on the electric charge in the atmosphere because newly arrived European travelers usually describe just their impressions of a tropical storm. In a country where the year is divided into two halves, the dry and the wet season, or as the Indians say in their expressive language, 'of sun and rain', it is interesting to follow meteorological phenomena as one season turns into the next.

The passage from the mouth of the Río Negro to Grand Para took only twenty to twenty-five days, so we could have gone down the Amazon as far as the Brazilian coast just as easily as returning by the Casiquiare to Caracas. We were told at San Carlos that political circumstances made it difficult to cross from Spanish to Portuguese colonies, but we did not know until our return to Europe what danger we would have been exposed to had we gone as far as Barcellos. It was known in Brazil, probably through newspapers, whose indiscretion is not helpful for travelers, that I was going to visit the Río Negro missions and examine the natural canal uniting the two river systems. In these deserted jungles the only instruments ever seen had been carried by the boundary commissioners. The Portuguese Government agents could not conceive how a sensible man could exhaust himself 'measuring lands that did not belong to him'. Orders had been issued to arrest me, seize my instruments, and especially my astronomical observations, so dangerous to the safety of the State. We were to be led along the Amazon to Grand Para, and then back to Lisbon. Fortunately, the Lisbon Government instantly ordered that I should not be disturbed but rather encouraged.

If the independent Indians have almost disappeared over the last century in those areas north of the Orinoco, it must not be concluded that fewer Indians exist at present than in the time of the bishop of Chiapas, Bartolomeo de las Casas. I have already proved in my work on Mexico how mistaken it is to assume the destruction and diminution of Indians in the Spanish colonies, as Ulloa has written 'Es cosa constante irse disminuyendo por todas partes el numero de los Indios' (There is everywhere a constant decrease in the number of Indians). There are still more than 6 million copper-colored races in both Americas, and though countless tribes and languages have died out it is beyond discussion that within the Tropics, where civilization arrived with Columbus, the number of Indians has considerably increased.

We entered into the cave following the rivulet, some 28 to 30 feet wide. We walked along the banks as far as the calcareous incrustations allowed us; frequently, when the current slipped between high clusters of stalactites, we were forced to walk along the river bed, only 2 feet deep. To our surprise we learned that this underground stream is the source to the Caripe river and becomes navigable for canoes a few leagues from here, after joining the Santa Maria river. Along the underground rivulet banks we found a quantity of palm-tree wood, remains of trunks used by Indians to climb to the cave's ceiling when searching for nests. The rings formed from the traces of the leaf stems are used as a perpendicular ladder.
