We could have included all these details in a work devoted solely to volcanoes in Peru and New Spain. Had I written the physical description of a single province I could have incorporated separate chapters on geography, mineralogy and botany, but how could I break the narrative of our travels, or an essay on customs and the great phenomena of general physics, by tiresomely enumerating the produce of the land, or describing new species and making dry astronomical observations? Had I decided to write a book that included in the same chapter everything observed from the same spot, it would have been excessively long, quite lacking in the clarity that comes from a methodical distribution of subject matter. Despite the efforts made to avoid these errors in this narration of my journey, I am aware that I have not always succeeded in separating the observations of detail from the general results that interest all educated minds. These results should bring together the influence of climate on organized beings, the look of the landscape, the variety of soils and plants, the mountains and rivers that separate tribes as much as plants. I do not regret lingering on these interesting objects for modern civilization can be characterized by how it broadens our ideas, making us perceive the connections between the physical and the intellectual worlds. It is likely that my travel journal will interest many more readers than my purely scientific researches into the population, commerce and mines in New Spain.

The Uruana inhabitants belong to those people of the savannah (Indios andantes), harder to civilize than those from the jungle (Indios del monte). They show a great aversion to agriculture and live exclusively from hunting and fishing. The men are tough, ugly, wild, vindictive and passionately fond of alcohol. They are 'omnivorous animals' in every sense. That is why other Indians consider them as barbarians and say, 'There is nothing, however disgusting it is, that an Otomac will not eat. While the Orinoco and its waters are low the Otomacs live on fish and turtles. They kill fish with astounding skill, hooting them with arrows when they surface. The river floods stop all fishing: it becomes as hard as fishing in deep sea. During the period of floods the Otomacs eat earth in prodigious amounts. We found pyramids of earth balls in their huts. The earth they eat is a fine oily clay, of a greyish-yellow; they cook it slightly so that its hard crust turns red due to the iron oxide in it.

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.

In the port of Encaramada we met some Caribs of Panapa with their cacique on their way up the Orinoco to take part in the famous fishing of turtle eggs. His pirogue was rounded towards the bottom like a bongo, and followed by a smaller canoe called a curiara. He was sitting under a kind of tent (toldo) built, like the sails, of palm leaves. His silent, cold reserve, and the respect others gave him, denoted an important person. The cacique was dressed like his people. All were naked, armed with bows and arrows, and covered in annatto, the dye made from Bixa orellana. The chief, the servants, the furniture, the sail and boat were all painted red. These Caribs are almost athletic in build and seemed far taller than any Indians we had seen up to now. Smooth, thick hair cut in a fringe like choir boys', eyebrows painted black, and a lively and gloomy stare give these Indians an incredibly hard expression. Having seen only skulls of these Indians in European collections we were surprised to see that their foreheads were more rounded than we had imagined. The fat, disgustingly dirty women carried their children on their backs. Their thighs and legs were bound by knotted cotton ligatures, leaving space for flesh to bulge out between the strands. It is noticeable that the Caribs are as careful about their exterior and dress as naked, painted men can be. They attach great importance to the shapes of certain parts of their bodies. A mother would be accused of indifference to her children if she did not artificially bind their calves in the fashion of the country. As none of our Apure Indians spoke the Carib language we could not ask the chief where he was going to camp to gather the turtle eggs.

The lake is usually full of fish; there are three species with soft flesh, which are not very tasty: the guavina, the bagre and the sardina. The last two reach the lake from streams. The guavina, which I sketched on the spot, was some 20 inches long and 3 to 5 inches wide. It is perhaps a new species of Gronovius's Erythrina. It has silver scales bordered with green. This fish is extremely voracious and destroys other species. Fishermen assured us that a little crocodile, the bava, which often swam near as we bathed, contributed to the destruction of the fish. We never managed to catch this reptile and examine it close up. It is said to be very innocent; yet its habits, like its shape, clearly resemble the alligator or Crocodilus acutus. It swims so that only the tips of its snout and tail show: it lies at midday on deserted beaches.

April 24th. A violent rainstorm forced us to embark before dawn. We left at two in the morning and had to abandon some books, which we could not find in the dark. The river runs straight from south to north, its banks are low and lined with thick jungle.
