At the end of April Bonpland and I had completed the observations we intended to make at the northern extreme of the torrid zone and were about to leave for Veracruz with Admiral Ariztizabal's fleet. But we were misled by false information concerning Captain Baudin's journey and decided to forgo our plan of passing Mexico on our way to the Philippine Islands. A newspaper announced that the two French sloops, the Géographie and the Naturaliste, had set sail for Cape Horn and would call in at Chile and Peru on their way to New Holland. This news shook me. I was reminded of my original intention in Paris when I had asked the Directorate to hasten Captain Baudin's departure. (138)

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.

After struggling a while with our plan to descend the Guarapiche river to the Golfo Triste, we took the direct road to the mountains. The Guanaguana and Caripe valleys are separated by an embankment or calcareous ridge famous for miles around for its name Cuchilla de Guanaguana. We found this way tiring because we still had to climb the cordilleras, but it is by no means as dangerous as they claim in Cumanà. In many places the path is no more than 14 or 15 inches wide; the mountain ridge it follows is covered with a short slippery grass; its sides are both very steep and the traveler who fell could roll some 700 to 800 feet down over that grass. However, the mountain has abrupt slopes, not precipices. The local mules are so sure-footed that they inspire confidence. They behave just like mules from Switzerland or the Pyrenees. The wilder a country, the more acute and sensitive is instinct in domestic animals. When the mules glimpse a danger they stop and turn their heads from right to left and raise and lower their ears as if thinking. They delay making up their minds, but always choose the right course of action if the traveler does not distract them or make them continue. In the Andes, during journeys of six and seven months, in mountains furrowed with torrents, the intelligence of horses and beasts of burden develops in a surprising way. You often hear mountain people say: 'I will not give you a mule with a comfortable gait, but the one that reasons best (la màs racional). This popular expression, the result of long experiences, contradicts far more convincingly than speculative philosophy those who claim that animals are simply animated machines.

After waiting for an hour we saw that our pirogue had safely crossed the raudal. We loaded our instruments and provisions and left the Guahibo rock. We began a journey that was quite dangerous. Above the cataract the river is some 800 toises wide and must be crossed obliquely at the point where the waters start rushing towards the fall. The men had been rowing for over twenty minutes when the pilot said that instead of advancing we were drifting back to the falls. Then there was a storm and heavy rain fell. Those anxious moments seemed to last for ever. The Indians whisper as they always do when in danger; but they rowed very hard and we reached the port of Maypures by nightfall.

The supposed gold mine of Cuchivano, which was the object of our trip, was nothing but a hole that had been cut in one of the strata of black marl, rich in pyrites. The marly stratum crosses the torrent and, as the water washes out metallic grains, the people imagine that the torrent carries gold because of the brilliancy of the pyrites. We were told that after the great earthquake of 1765 the Juagua river waters were so filled with gold that 'men came from great distances and unknown countries' to set up washing places on the spot. They disappeared over night, having collected masses of gold. Needless to add that this is a fable. Some direct experiments made with acids during my stay at Caracas proved that the Cuchivano pyrites are not at all auriferous. My disbelief upset our guides. However much I said and repeated that from the supposed gold mine the most that could be found was alum and sulphate of iron, they continued to gather secretly all the pyrite fragments they saw sparkling in the water. The fewer mines there are in a country, the more the inhabitants hold exaggerated ideas about how easily riches are extracted from the depths of the earth. How much time was lost during our five-year voyage exploring ravines, at the insistence of our hosts, where pyrite strata have for centuries been called by the pretentious name of minas de oro! We have smiled so often seeing men of all classes - magistrates, village priests, serious missionaries - all grinding amphibole or yellow mica with endless patience, desperate to extract gold by means of mercury! This rage for searching for mines amazed us in a climate where the earth needs only to be slightly raked in order to produce rich harvests.

April 13th. Early in the morning we passed the Tabaje rapids and landed again. Father Zea, who accompanied us, wanted to say mass in the new San Borja mission established two years before. We found six huts inhabited by uncatechized Indians. They were no different from wild Indians. Only their large black eyes showed more liveliness than those living in older missions. They refused our brandy without even trying it. The young girls had their faces marked with round black spots. The rest of their bodies were not painted. Some of the men had beards, and they seemed proud. Holding our chins they showed through signs that they were made like us. I was again struck by how similar all the Orinoco Indians are. Their look is somber and sad, not hard or ferocious. Without any notions about the practices of the Christian religion they behaved quite decently in the church. Indians like representations; they submit themselves momentarily to any nuisance provided they are sure of being stared at. Just before the moment of communion they make signs to show that the priest was about to bring the chalice to his lips. Apart from this gesture they stay immobile, in their imperturbable apathy.
