At the Divina Pastora hospice the path turns to the north-east along a stretch without trees, formerly leveled by the waters. There we found not only cacti, tufts of cistus-leaved tribulus and the beautiful purple euphorbia, cultivated in Havana gardens under the odd name of Dictamno real, but also the avicennia, the allionia, the sesuvium, the thalinum and most of the portulaceous plants that grow on the banks of the Gulf of Cariaco. This geographical distribution of plants appears to designate the limits of the ancient coast and to prove that the hills along the southern side, which we were following, once formed islands separated from the continent by an arm of the sea.

Having outlined the general aim, I will now briefly glance at the collections and observations we made. The maritime war during our stay in America made communications with Europe very uncertain and, in order for us to avoid losses, forced us to make three different collections. The first we sent to Spain and France, the second to the United States and England, and the third, the most considerable, remained constantly with us. Towards the end of our journey this last collection formed forty-two boxes containing a herbal of 6, equinoctial plants, seeds, shells and insects, and geological specimens from Chimborazo, New Granada and the banks of the Amazon, never seen in Europe before. After our journey up the Orinoco, we left a part of this collection in Cuba in order to pick it up on our return from Peru and Mexico. The rest followed us for five years along the Andes chain, across New Spain, from the Pacific shores to the West Indian seas. The carrying of these objects, and the minute care they required, created unbelievable difficulties, quite unknown in the wildest parts of Europe. Our progress was often held up by having to drag after us for five and six months at a time from twelve to twenty loaded mules, change these mules every eight to ten days, and oversee the Indians employed on these caravans. Often, to add new geological specimens to our collections, we had to throw away others collected long before. Such sacrifices were no less painful than what we lost through accidents. We learned too late that the warm humidity and the frequent falls of our mules prevented us from preserving our hastily prepared animal skins and the fish and reptiles in alcohol. I note these banal details to show that we had no means of bringing back many of the objects of zoological and comparative anatomical interest whose descriptions and drawings we have published. Despite these obstacles, and the expenses entailed, I was pleased that I had decided before leaving to send duplicates of all we had collected to Europe. It is worth repeating that in seas infested with pirates a traveler can only be sure of what he takes with him. Only a few duplicates that we sent from America were saved, most fell into the hands of people ignorant of the sciences. When a ship is held in a foreign port, boxes containing dried plants or stones are merely forgotten, and not sent on as indicated to scientific men. Our geological collections taken in the Pacific had a happier fate. We are for their safety to the generous work of Sir Joseph Banks, President of the Royal Society of London, who, in the middle of Europe's political turmoils, has struggled ceaselessly to consolidate the ties that unite scientific men of all nations.

A historical narrative covers two quite different aims: whatever happens to the traveler; and the observations he makes during his journey. Unity of composition, which distinguishes good work from bad, can be sought only when the traveler describes what he has seen with his own eyes, and when he has concentrated on the different customs of people, and the great phenomena of nature, rather than on scientific observations. The most accurate picture of customs is one that deals with man's relationships with other men What characterizes savage and civilized life is captured either through the difficulties encountered by a traveler or by the sensations he feels. It is the man himself we wish to see in contact with the objects around him. His narration interests us far more if a local coloring informs the descriptions of the country and its people. This is what excites us in the narrations of the early navigators who were driven more by guts than by scientific curiosity and struggled against the elements as they sought a new world in unknown seas.

From the time we entered the torrid zone we never tired of admiring, night after night, the beauty of the southern sky, which as we advanced further south opened up new constellations. A strange, completely unknown feeling is awoken in us when nearing the Equator and crossing from one hemisphere to another; the stars we have known since infancy begin to vanish. Nothing strikes the traveler more completely about the immense distances that separate him from home than the look of a new sky. The grouping of great stars, some scattered nebulae that rival the Milky Way in splendor, and regions that stand out because of their intense blackness, give the southern sky its unique characteristics. This sight strikes the imagination of those who even, without knowledge of the exact sciences, like to stare at the heavens as if admiring a lovely country scene, or a majestic site. You do not have to be a botanist to recognize immediately the torrid zone by its vegetation. Even those with no inkling of astronomy know they are no longer in Europe when they see the enormous constellation of the Ship or the brilliant Clouds of Magellan rise in the night sky. Everything on earth and in the sky in the tropical countries takes on an exotic note.

The fresh north-east wind blew us at full sail towards the boca de la tortuga. At eleven in the morning we landed on an island, which the Indians of the Uruana mission regard as their own, situated in the middle of the river. This island is famous for the fishing of turtles or, as is said here, the cosecha, or annual harvest of eggs. We found a group of Indians camping in palm-leaf huts. This camp-site had over 300 people in it. As we had been used, since San Fernando de Apure, to seeing only deserted beaches, we were struck by the bustle. Apart from Guamos and Otomacs, seen as two wild and untamed tribes, there were Caribs and other Indians from the Lower Orinoco. Each tribe camped separately, and could be recognized only by the different paints on their skins. We also found, among this noisy reunion, some white men, mainly pulperos, the small traders from Angostura, who had come upstream to buy turtle-egg oil from the Indians. The Uruana missionary, from Alcalà de Henares, came to meet us, extremely surprised to see us there. After inspecting our instruments, he exaggeratedly described the hardships we would suffer going further upstream beyond the cataracts. The purpose of our journey seemed very mysterious to him. 'How is anyone to believe, he said, 'that you left your homeland to come up this river to be eaten by mosquitoes and measure lands that do not belong to you? Luckily we were armed with recommendations from the guardian father of the Franciscan missions, while the brother-in-law of the Barinas governor accompanying us soon resolved the doubts that the whites there had about our dress, accent and arrival on the island. The missionary invited us to share a frugal meal of bananas and fish with him. He told us he had come to camp with the Indians during the harvesting of the eggs 'to celebrate open-air mass every day, to get oil for the lights in his church, and above all to govern this Republica de Indios y Castellanos where individuals wanted to profit selfishly with what God had given to everybody'.

Like all the Indian tribes that I know the Chaimas have small, slender hands. Contrary to this, their feet are large, and their toes remain extremely mobile. All the Chaimas resemble each other, as if they were all related, and this is all the more evident because between twenty and fifty years old, age is not indicated by wrinkling skin, white hair or body decrepitude. When you enter a hut it is hard to differentiate a father from a son, one generation from another. I think that this family resemblance has two different causes: the local position of the Indian villages, and the lack of intellectual culture. Indian nations are subdivided into an infinity of tribes, all hating each other, and never allied even if speaking the same language or living on the same river or nearby hill. This characteristic is preserved in the missions where marriages are made only within tribes. This blood link that unites a whole tribe is naively illustrated by those Spanish-speaking Indians who designate members of the same tribe as mis parientes (my relatives).

One place where spiky cacti of great size grow together is almost impossible to walk through. These areas, known as tunales, not only prevent bare-chested Indians from entering, but also anyone fully dressed. During our solitary walks we tried several times to penetrate the tunal that crowns the hill with the fort, along which runs a path. There we found thousands of examples of this strange plant. At times nightfall surprised us as there is no twilight. Then this place becomes dangerous, for the rattlesnake (Crotalus cumanensis), the coral and other poisonous snakes seek out these hot places to deposit their eggs in the sand.
