The underground noise so frequently heard during earthquakes is not usually related to the strength of the shocks. At Cumana the noise constantly preceded the shocks, while at Quito, and recently at Caracas and in the West Indies, a noise like the discharge of a battery of guns was heard a long time after the shocks had ended. A third kind of phenomenon, and the most remarkable of all of them, is the rolling of those underground thunders that last several months without being accompanied by the slightest tremors.

The preparation of sugar, its boiling, and the claying, is not well done in Terra Firma because it is made for local consumption. More papelòn is sold than either refined or raw sugar. Papelòn is an impure sugar in the form of little yellowish-brown loaves. It is a blend of molasses and mucilaginous matter. The poorest man eats papelòn the way in Europe he eats cheese. It is said to be nutritious. Fermented with water it yields guarapo, the favorite local drink.

In the lands of the Río Negro Indians we found several of those green stones known as 'Amazon stones' because Indians claim that they come from a country of 'women without men', or 'women living alone'. Superstition attaches great importance to these stones, which are worn as amulets round the neck as popular belief claims they protect wearers from nervous diseases, fevers and poisonous snake bites. Because of this they have for centuries been traded between the Indians of the northern Orinoco and those in the south. The Caribs made them known on the coast. Up to a few years ago during debates about quinine these green stones were considered an efficient febrifuge in enlightened Europe; if we can count on the credulity of Europeans, there is nothing odd about Spanish colonizers appreciating these amulets as much as the Indians, or that these stones are sold at high prices. Usually they are shaped into cylinders with holes down the sides, and covered in inscriptions and figures. But it is not today's Indians who have perforated holes in such hard stones or carved animals and fruit. This work suggests another, older culture. The actual inhabitants of the torrid zone are so ignorant of how to carve hard stone that they think the green stone comes from soft earth, and that it hardens when carved.

When a traveler recently arrived from Europe steps into South American jungle for the first time he sees nature in a completely unexpected guise. The objects that surround him only faintly bring to mind those descriptions by famous writers of the banks of the Mississippi, of Florida and of other temperate regions of the New World. With each step he feels not at the frontiers of the torrid zone but in its midst; not on one of the West Indian Islands but in a vast continent where everything is gigantic; mountains, rivers and the masses of plants. If he is able to feel the beauty of landscape, he will find it hard to analyse his many impressions. He does not know what shocks him more: whether the calm silence of the solitude, or the beauty of the diverse, contrasting objects, or that fullness and freshness of plant life in the Tropics. It could be said that the earth, overloaded with plants, does not have sufficient space to develop. Everywhere tree trunks are hidden behind a thick green carpet. If you carefully transplanted all the orchids, all the epiphytes that grow on one single American fig tree (Ficus gigantea) you would manage to cover an enormous amount of ground. The same lianas that trail along the ground climb up to the tree-tops, swinging from one tree to another 100 feet up in the air. As these parasitical plants form a real tangle, a botanist often confuses flowers, fruit and leaves belonging to different species.

The ground of the island rises to form an amphitheatre and, as in Peru and Mexico, contains in miniature all the possible climates, from African heat to alpine cold. (14) The mean temperatures of Santa Cruz, the port of Orotava, Orotava itself and La Laguna form a descending series. In southern Europe the change of seasons is too strongly felt to offer the same advantages. Tenerife on the other hand, on the threshold of the Tropics and a few days' journey from Spain, benefits from a good part of what nature has lavished in the Tropics. Its flora include the beautiful and imposing bananas and palms. He who is able to feel nature's beauty finds in this precious island a far more effective remedy than the climate. Nowhere else in the world seems more appropriate to dissipate melancholy and restore peace to troubled minds than Tenerife and Madeira. These effects are due not only to the magnificent situation and to the purity of air, but above all to the absence of slavery, which so deeply revolts us in all those places where Europeans have brought what they call their 'enlightenment and their 'commerce' to their colonies

Frightened about being exposed too long to the unhealthy Cartagena airs we moved to the Indian village of Turbaco (once called Tarasco) on the 6th of April. It is situated in a delicious place where the jungle begins some 5 leagues south-south-east of Pipa. We were happy to leave a foul inn (fonda) packed with soldiers left over from General Rochambeau's unfortunate expedition. (144) Interminable discussions about the need to be cruel to the blacks of Santo Domingo reminded me of the opinions and horrors of the sixteenth-century conquistadores. Pombo lent us his beautiful house in Turbaco, built by Archbishop Viceroy Gòngora. We stayed as long as it took us to prepare for our journey up the Magdalena, and then the long land trip from Honda to Bogotà, Popoyàn and Quito. Few stays in the Tropics have pleased me more. The village lies some 180 toises above sea-level. Snakes are very common and chase rats into the houses. They climb on to roofs and wage war with the bats, whose screaming annoyed us all night. The Indian huts covered a steep plateau so that everywhere you can view shady valleys watered by small streams. We especially enjoyed being on our terrace at sunrise and sunset as it faced the Sierra Nevada de Santa Marta, some 35 leagues distant. The snow-covered peaks probably San Lorenzo - are clearly seen from Turbaco when the wind blows and brings cooler air. Thick vegetation covers the hills and plains between the Mahates dyke and the snowy mountains: they often reminded us of the beautiful Orinoco mountains. We were surprised to find, so close to the coast in a land frequented by Europeans for over three centuries, gigantic trees belonging to completely unknown species, such as the Rhinocarpus excelsa (which the creoles call caracoli because of its spiral-shaped fruit), the Ocotea turbacensis and the mocundo or Cavanillesia platanifolia, whose large fruit resemble oiled paper lanterns hanging at the tip of each branch.
