During my navigation up the South American rivers, and over land, I had written a very brief itinerary where I described on the spot what I saw when I climbed the summit of a volcano or any other mountain, but I did not continue my notes in the towns, or when busy with something else. When I did take notes my only motive was to preserve those fugitive ideas that occur to a naturalist, to make a temporary collection of facts and first impressions But I did not think at the time that these jotted-down notes would form the basis of a work offered to the public. I thought that my journey might add something to science, but would not include those colorful details that are the main interest in journeys.

The city, dominated by the fort, lies at the foot of a hill without greenery. Not one bell-tower nor one dome attract the traveler from afar; just a few tamarind trees and coconut and date palms stand out above the flat-roofed houses. The surrounding plains, especially near the sea, appear sad, dusty and arid, while fresh, luxuriant vegetation marks out the winding river that divides the city from its outskirts and the European settlers from the copper-colored Indians. The isolated, bare and white San Antonio mountain, with its fort, reflects a great mass of light and heat: it is made of breccia, whose strata contain fossil marine life. Far away towards the south you can make out a dark curtain of mountains. They are the high calcareous New Andalusian alps, topped with sandstone and other recent geological formations. Majestic forests cover this inland mountain chain linked along a forested valley with the salty, clayey and bare ground around Cumana. In the gulf and on its shores you can see flocks of fishing herons and gannets, awkward, heavy birds, which, like swans, sail along the water with their wings raised. Nearer the inhabited areas, you can count thousands of gallinazo vultures, veritable flying jackals, ceaselessly picking at carcasses. A gulf whose depths contain hot thermal springs divides the secondary from the primary and schistose rocks of the Araya peninsula. The two coasts are bathed by a calm blue sea lightly rippled by a constant breeze. A dry, pure sky, only lightly clouded at sunset, lies above the sea, over a peninsula devoid of trees and above the Cumana plains, while one sees storms building up and bursting into fertile downpours around the inland mountain peaks.

From the Manimi rock there is a marvelous view. Your eyes survey a foaming surface that stretches away for almost 2 leagues. In the middle of the waves rocks as black as iron, like ruined towers, rise up. Each island, each rock, is crowned by trees with many branches; a thick cloud floats above the mirror of the water and through it you see the tops of tall palms. What name shall we give these majestic plants? I guess that they are vadgiai, a new species, more than 80 feet high. Everywhere on the backs of the naked rocks during the rainy season the noisy waters have piled up islands of vegetation. Decorated with ferns and flowering plants these islands form flower-beds in the middle of exposed, desolate rocks. At the foot of the Manimi rock, where we had bathed the day before, the Indians killed a 7. snake, which we examined at leisure. The Macos called it a camudu. It was beautiful, and not poisonous. I thought at first that it was a boa, and then perhaps a python. I say 'perhaps' for a great naturalist like Cuvier appears to say that pythons belong to the Old World, and boas to the New. I shall not add to the confusions in zoological naming by proposing new changes, but shall observe that the missionaries and the latinized Indians of the mission clearly distinguish the tragavenado (boa) from the culebra de agua, which is like the camudu.

The same reasons that slowed our communications also delayed the publication of our work, which has to be accompanied by a number of engravings and maps. If such difficulties are met when governments are paying, how much worse they are when paid by private individuals. It would have been impossible to overcome these difficulties if the enthusiasm of the editors had not been matched by public reaction. More than two thirds of our work has now been published. The maps of the Orinoco, the Casiquiare and the Magdalena rivers, based on my astronomical observations, together with several hundred plants, have been engraved and are ready to appear. I shall not leave Europe on my Asian journey before I have finished publishing my travels to the New World.

The farmers and their slaves cut a path through the jungle to the first Juagua river waterfall, and on the 10th of September we made our excursion to the Cuchivano crevice. Entering the cave we saw a disemboweled porcupine and smelled the stink of excrement, similar to that of European cats, and knew that a jaguar had been near by. For safety the Indians returned to the farm to fetch small dogs. It is said that when you meet a jaguar in your path he will leap on to a dog before a man. We did not follow the bank of the torrent, but a rocky wall overhanging the water. We walked on a very narrow ledge along the side of a precipice with a drop of some 200 to 300 feet. When it narrowed, so that we could not walk along it any further, we climbed down to the torrent and crossed it on foot, or on the backs of slaves, to climb up the other side. Climbing is very tiring, and you cannot trust the lianas, which, like thick rope, hang from tree-tops. Creepers and parasites hang loosely from the branches they grip; their stalks together weigh a lot, and if you slip and grab one of the lianas you risk bringing down a tangle of green branches. The vegetation became impenetrable the more we advanced. In some places the roots of trees grew in the existing cracks between strata and had burst the calcareous rock. We could hardly carry the plants we picked at each step. The canna, the heliconia with pretty purple flowers, the costus and other plants from the Amomum genus reach here the height of 8 to 50 feet. Their tender, fresh green leaves, their silky sheen and the extraordinary development of their juicy pulp contrast with the brown of the arborescent ferns whose leaves are so delicately jagged. The Indians made deep incisions in the tree trunks with their long knives to draw our attention to the beauty of the red-and gold-colored woods, which one day will be sought after by our furniture makers. They showed us a plant with composite flowers that reaches some 20 feet high (Eupatorium laevigatum), the so-called 'Rose of Belveria' (Brownea racemosa), famous for the brilliance of its purple flowers, and the local 'dragon's blood', a species of euphorbia not yet catalogued, whose red and astringent sap is used to strengthen the gums. They distinguished species by their smell and by chewing their woody fibers. Two Indians, given the same wood to chew, pronounced, often without hesitation, the same name. But we could not take advantage of our guides' wisdom, for how could they reach leaves, flowers and fruit (53) growing on branches some 50 to 60 feet above the ground? We were struck in this gorge by the fact that the bark of the trees, even the ground, were covered in moss and lichen.

Guanaguana still does not have a church. The old priest, who had lived for more than thirty years in the American jungles, pointed out that the community's money, meaning the product of the Indians' work, should first be spent on building the missionary house; secondly on building a church; and lastly on their clothes. He seriously insisted that this order could not be altered on any account. The Indians can wait their turn as they prefer walking around completely naked to wearing the scantiest clothes. The spacious padre's house had just been finished and we noted with surprise that the terraced roof was decorated with a great number of chimneys that looked like turrets. Our host told us that this was done to remind him of his Aragonese winters, despite the tropical heat. The Guanaguana Indians grow cotton for themselves, the church and the missionary. The produce is supposed to belong to the community; it is with this communal money that the needs of the priest and altar are looked after. They have simple machines that separate the seed from the plant. Wooden cylinders of tiny diameter between which the cotton passes are activated, like a spinning-wheel, by pedals. However, these primitive machines are very useful and other missions are beginning to imitate them. But here, as in all places where nature's fertility hinders the development of industry, only a few hectares are converted into cultivated land, and nobody thinks of changing that cultivation into one of alimentary plants. Famine is felt each time the maize harvest is lost to a long drought. The Guanaguana Indians told us an amazing story that happened the year before when they went off with their women and children and spent three months al monte, that is, wandering about in the neighboring jungle and living off juicy plants, palm cabbages, fern roots and wild fruit. They did not speak of this nomadic state as one of deprivation. Only the missionary lost out because his village was left completely abandoned, and the community members, when they returned from the woods, appeared to be less docile than before.

On the morning of the 27th of February we visited the hot springs of La Trinchera, 3 leagues from Valencia. They flow more fully than any we had seen until then, forming a rivulet, which in the dry season maintains a depth of some 2 feet 8 inches of water. The carefully taken water temperature was 90.3°C. We had breakfast near the spring: our eggs were cooked in less than four minutes in the hot water. The rock from which the spring gushes is of real coarse-grained granite. Whenever the water evaporates in the air, it forms sediments and incrustations of carbonate of lime. The exuberance of the vegetation around the basin surprised us. Mimosas with delicate pinnate leaves, clusias and figs send their roots into the muddy ground, which is as hot as 85°C. Two currents flow down on parallel courses, and the Indians showed us how to prepare a bath of whatever temperature you want by opening a hole in the ground between the two streams. The sick, who come to La Trinchera to take steam baths, build a kind of framework with branches and thin reeds above the spring. They lie down naked on this frame, which, as far as I could see, was not very strong, perhaps even dangerous.
