Nothing can compare to the majestic tranquillity of the stars in the sky in this solitary place. At nightfall, when we stared at the point where the horizon meets the meadows on this gently rolling plain, it seemed, as later in the Orinoco steppes, as if we were seeing the surface of an ocean supporting the starry vault. The tree at whose feet we sat, the luminous insects dancing in the air, the shining constellations of the Southern hemisphere, everything reminded us that we were far from our homeland. And if, in the middle of this exotic nature, the sound of cow bells or the bellowing of a bull came from the small valleys, memories of our native land were suddenly awoken. It was as if we heard distant voices echoing across the ocean, magically carrying us from one hemisphere to another. How strangely mobile is man's imagination, eternal source of his joys and pains!

Our mules waited for us on the left bank of the Orinoco. The plant collections and geological specimens brought from Esmeralda and the Río Negro had greatly increased our baggage. It would have been dangerous to leave our herbals behind, but this added weight meant we now faced a tediously slow journey across the llanos. The heat was excessive due to the bare ground's reverberations. The thermometer by day recorded between 30°C and 34°C, and at night 27°C to 28°C. Like everywhere in the Tropics it was less the actual degree of heat than its duration that affected our bodies. We spent thirteen days crossing the steppes, resting a little in the Carib missions and in the village of Payo.

There are moments in life when it is useless to call on reason. I was very scared. However, I was sufficiently in control of myself to remember what the Indians had advised us to do in such circumstances. I carried on walking, without breaking into a run or moving my arms, and thought I noted that the wild beast had its eye on a herd of capybaras swimming in the river. The further away I got the more I quickened my pace. I was so tempted to turn round and see if the cat was chasing me! Luckily I resisted this impulse, and the tiger remained lying down. These enormous cats with spotted skins are so well fed in this country well stocked with capybara, peccaries and deer that they rarely attack humans. I reached the launch panting and told my adventure story to the Indians, who did not give it much importance.

Our first excursion to the Araya peninsula was followed by another more important and instructive one to the mountain missions of the Chaima Indians. Such a variety of objects attracted our attention. We found ourselves in a country bristling with forests on our way to visit a convent shaded by palm trees and arborescent ferns in a narrow valley which was deliciously fresh, despite being in the middle of the torrid zone. In the surrounding mountains there are eaves inhabited by thousands of nocturnal birds; and, what struck our imagination more than all the marvels of the physical world, even further up we found a people until recently still nomadic, hardly free from a natural, wild state, but not barbarians, made stupid more from ignorance than from long years of being brutalized. What we knew about history increased our interest in these people. The promontory of Paria was what Columbus first saw of this continent; these valleys ended there, devastated first by the warlike, cannibalistic Caribs, then by the mercantile and orderly European nations. If the Spaniards visited these shores it was only to get, either by violence or exchange, slaves, pearls, gold and dye-woods; they tried to dignify their motives for such an insatiable greed with the pretence of religious zeal.

Twelve years have elapsed since I left Europe to explore the interior of the New Continent. From my earliest days I was excited by studying nature, and was sensitive to the wild beauty of a landscape bristling with mountains and covered in forests. I found that travelling out there compensated for a hard and often agitated life. But pleasure was not the only fruit of my decision to contribute to the progress of the physical sciences. For a long time I had prepared myself for the observations that were the main object of my journey to the torrid zone. I was equipped with instruments that were easy and convenient to use, made by the ablest artists, and I enjoyed the protection of a government that, far from blocking my way, constantly honored me with its confidence. I was supported by a brave and learned friend whose keenness and equanimity never let me down, despite the exhaustion and dangers we faced.

The location of the town of Santa Cruz is similar to La °, the busiest port in the province of Caracas. The heat is excessive in both places, but Santa Cruz is sadder. On a deserted sandy beach, houses of a dazzling white with flat roofs and windows without panes lie close to a rocky cliff stripped of vegetation. A fine stone quay and public walk planted with poplars are the only attraction in that monotonous picture. From Santa Cruz the peak seems far less picturesque than it does from the port of Orotava. There a smiling and richly cultivated plain contrasts with the wild appearance of the volcano. From the groves of palm and banana trees on the shore to the region of strawberry trees, laurels and pine the volcanic rock is covered with luxuriant vegetation. It is easy to see why the inhabitants of the beautiful climates of Greece and Italy thought they had discovered one of the Fortunate Isles on the western part of Tenerife. The eastern Santa Cruz side is everywhere marked with sterility.

We were received with eagerness by the monks of the hospice. The father superior was away but, notified of our departure from Cumanà, be had taken great pains to ensure our comfort at the convent. There was an inner cloister, typical of all Spanish monasteries. We used this enclosed space to install our instruments and get them working. In the convent we discovered a varied company; young monks recently arrived from Spain before being sent out to different missions, while old, sick missionaries recuperated in the healthy air of the Caripe bills. I was lodged in the father superior's cell, which had a notable library. To my surprise I found Feijòo's Teatro crítico, the Lettres édifiantes, and L'abbé Nollet's Traité d'électricité. Science has progressed to even the American jungles. The youngest of the Capuchin monks had brought with him a Spanish translation of Chaptal's treatise on chemistry, (56) which he intended to study in the isolation of the mission where he was to be abandoned on his own for the rest of his days. I doubt that the desire to learn can be kept alive in a young monk isolated on the banks of the Tigre river; but what is certain, and an honour to the spirit of this century, is that during our long stay in South American missions we never saw the least sign of intolerance.
