On the 20th of June, before sunrise, we set off for the Villa de Laguna, some 350 toises (13) above Santa Cruz harbor. The narrow and tortuous path leading to La Laguna climbs along a torrent, which in the rainy season turns into fine cascades. Near the town we met some white camels, barely laden. These animals are mainly used to transport goods from the customs house to the merchants. Camels are not numerous in Tenerife, while in Lanzarote and Fuerteventura there are thousands.

I have mentioned flying fish in order to draw the attention of naturalists to the extraordinary size of their natatory bladder. As this bladder takes up more than half the fish's body volume it probably contributes to its lightness. One could say that this reservoir of air 15 more adapted for flying than swimming. Flying fish, like almost all animals with gills, enjoy the possibility of breathing for a long time with the same organs both in air and in water. They pass much of their time in the air, although flying does not make them less wretched. If they leave the sea to escape from the voracious dolphin they meet frigate-birds, albatrosses and other birds in the air, which seize them in mid-flight. Thus, on the Orinoco banks, herds of capybara (Cavia capybara) rush from the water to escape crocodiles and fall prey to jaguars waiting for them on the banks. I doubt that flying fish leap from the water solely to escape their predators. Like swallows they shoot forward in thousands in straight lines, always against the waves. In our climate, by a clear-water river struck by the sun's rays, we often see single fish, with no reason to fear anything, leap into the air as if they enjoyed breathing air. Why aren't these games more frequent and prolonged with flying fish who, thanks to their pectoral fins and extreme lightness, fly easily in the air?

They grow banana and cassava, but not maize. Like the majority of Orinoco Indians, those in Maypures also make drinks that could be called nutritious. A famous one in the country is made from a palm called the seje, which grows wild in the vicinity. I estimated the number of flowers on one cluster at 44, the fruit that fall without ripening amount to 8,000. These fruit are little fleshy drupes. They are thrown into boiling water for a few minutes to separate the pulp, which has a sweet taste, from the skin, and are then pounded and bruised in a large vessel filled with water. Taken cold, the infusion is yellowish and tastes like almond milk. Sometimes papelòn (unrefined sugar) or sugar cane is added. The missionary said that the Indians become visibly fatter during the two or three months when they drink this seje or dip their cassava cakes in it. The piaches, or Indian shamans, go into the jungle and sound the botuto (the sacred trumpet) under seje palm trees 'to force the tree to give a good harvest the following year'.

I met the Swedish Consul Skiöldebrand, who passed through Paris on his way to embark in Marseille on a missionto bring gifts to the Dey of Algiers. That respectable gentleman had lived for a long time on the African coast and, as he was well known in theAlgerian Court, could get me authorization to visit the Atlas mountains. Every year he despatched a ship to Tunis, which brought pilgrims to Mecca, and he promised to let me go to Egypt that way. I did not hesitate to seize that chance and was convinced Icould carry out the plan I had hatched before my arrival in France. Up until then no geologist had ever exploredthe high mountain ranges that in Morocco reach the perpetual snows. Iquickly completed my collection of instruments and obtained books thatdealt with the countries I was to visit. I said good-bye to my brother, whose example and advice had helped guidemy thinking. He approved of my motives for wanting to abandon Europe; a'secret voice told me we would see each other again. I left Paris eager toembark for Algeria and Egypt, andchance - so often playing a decisive role in human lives - had it that Iwould see my brother again after returning from the Amazon and Peru, putting a foot on African soil.

The Indians of the missions, remote from all civilization, are influenced solely by physical needs, which they satisfy very easily in their favorable climate, and therefore tend to lead dull, monotonous lives, which are reflected in their facial expressions.

For the past year so many obstacles had crossed my path that I couldhardly believe that at last my innermost desires would be fulfilled. Weleft Madrid in the middle of May and crossed Old Castile and the kingdomsof Le-n and Galicia to La Coruña, where we were to embark for the island of Cuba. The winter had been long and hard but now, duringour journey, we enjoyed the mild temperatures of spring that in the southusually begin in March or April. Snow still covered the tall granitic peaksof the Guadarrama but in the deep Galician valleys, which reminded me of the picturesque scenery ofSwitzerland and the Tyrol, the rocks were covered in flowering cistus andarborescent heaths. The traveler is happy to quit the Castilian plainsdevoid of vegetation and their intense winter cold and summers of oppressive heat.

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.
