The Pizarro had orders to anchor off the island of Lanzarote, of the seven large Canary Islands, to find out if the English werestill blockading the Santa Cruz bay. From the 15th we were dubious aboutwhich route to follow. Finally, on the 16th, at two in the afternoon, we sighted land, which looked like alittle cloud stuck on the horizon. At five, with the sun very low, we couldclearly see the island of Lanzarote before us.

May 10th. Overnight our canoe was loaded and we set off a little before dawn to go up the Río Negro to the mouth of the Casiquiare and begin our researches on the true course of this river linking the Orinoco and Amazon. The morning was beautiful, but as the heat rose the sky began to cloud over. The air is so saturated with water in these forests that water bubbles become visible at the slightest increase of evaporation on the earth's surface. As there is no breeze the humid strata are not replaced and renewed by drier air. This clouded sky made us gloomier and gloomier. Through this humidity Bonpland -lost the plants he had collected; for my part I feared finding the same Río Negro mists in the Casiquiare valley. For more than half a century nobody in the missions has doubted the existence of communications between the two great river systems: the important aim of our journey was reduced to fixing the course of the Casiquiare by astronomic means, especially at its point of entry into the Río Negro, and its bifurcation with the Orinoco. Without sun or stars this aim would have been frustrated, and we would have been uselessly exposed to long, weary deprivation. Our travelling companions wanted to return by the shortest journey, along the Pimichín and its small rivers; but Bonpland preferred, like myself, to persist in the original plan we had traced out while crossing the Great Cataracts. We had already traveled by canoe from San Fernando de Apure to San Carlos along the Apure, Orinoco, Atabapo, Temi, Tuamini and Río Negro for over 180 leagues. In entering the Orinoco by the Casiquiare we still had some 320 leagues to cover from San Carlos to Angostura. It would have been a shame to let ourselves be discouraged by the fear of a cloudy sky and the Casiquiare mosquitoes. Our Indian pilot, who had recently visited Mandavaca, promised us sun and 'those great stars that eat up clouds' once we had left the black waters of the Guaviare. So we managed to carry out our first plan and returned to San Fernando along the Casiquiare. Luckily for our researches the Indian's prediction was fulfilled. The white waters brought us a clear sky, stars, mosquitoes and crocodiles.

On the road to the harbor we were struck by the countless phosphorescent insects (Cocuyo, Elater noctilucus). The grass, the branches and the leaves of trees all shone with that reddish, flickering light. It seemed as if the stars had fallen on to the savannah! In the poorest hut in the country fifteen cocuyos, placed in a gourd pierced with holes, give sufficient light to look for things at night. Shaking the gourd excites the animals and increases the luminous discs on their bodies. A young woman at Trinidad told us that during a long passage from the mainland she used the phosphorescent cocuyos when she wanted to nurse her baby at night. The captain of the ship would use only cocuyos lights so as not to attract pirates.

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.

The Río Negro and the Jupura are two tributaries of the Amazon comparable in length to the Danube, whose upper parts belong to Spain and whose lower reaches are occupied by Portugal. In these majestic rivers people have gathered in those places where civilization is most ancient. The banks of the Upper Jupura or Caqueta have been cultivated by missionaries who came down from the mountains of Popayan and Neiva. From Mocoa to the confluence with Caguan there are many Christian settlements, while in the Lower Jupura the Portuguese have founded hardly a few villages. Along the Río Negro, on the other hand, the Spaniards have not been able to rival their neighbors. How can they rely on a people so distanced from has the province of Caracas? Steppes and virtually deserted jungle some 160 leagues thick separate the cultivated parts of the river bank from the four missions of Maroa, Tomo, Davipe and San Carlos.
