It took us five long days from the Villa de Pao to the port of Nueva Barcelona. As we got closer the sky became clearer, the ground more dusty and the air more burning hot This oppressive heat does not arise from the temperature but from fine sand floating in the air, which irradiates heat in all directions, and whips your face and the ball of the thermometer. In fact I never saw the mercury rise above 45. once in this sand wind in America.

We spent only one day at San Fernando de Atabapo, despite the village, with its pirijao palms and their peach-like fruit, promising us a delightful refuge. Tame pauxis (Crax alector) ran round the Indian huts; in one of which we saw a very rare monkey that lives on the banks of the Guaviare. It is called the caparro, which I have made known in my Observations on Zoology and Comparative Anatomy. Its hair is grey and extremely soft to touch. It has a round head, and a sweet, agreeable expression.

At nightfall we ordered our instruments to be disembarked; and to our relief none had been damaged. We hired a spacious and well-situated house for our astronomical observations. When the sea wind blew we enjoyed the cool air. The windows did not have glass panes, nor the paper squares that replace glass in most Cumana houses. All the passengers on the Pizarro left the ship, but those with the malignant fever recovered very slowly. Some were still terribly pale and emaciated after a month of illness, despite the care lavished on them by their compatriots. In the Spanish colonies the hospitality is such that a European who arrives without money or recommendations is almost sure to find help should he disembark sick in any port. Catalans, Galicians and Basques maintain an intense trade with America, where they form three distinct bodies, and exercise a great influence on the customs, industry and commerce of the colonies. The poorest inhabitant of Sitges or Vigo may be assured of being received in the house of a Catalan or Galician merchant (pulpero) (26) whether in Chile or Mexico or the Philippines. I have witnessed moving examples where strangers are looked after assiduously for years. Some may say that hospitality is no virtue in a land with such a magnificent climate, with plenty of food, and where indigenous plants supply efficient medicines, and a sick person finds necessary refuge in a hammock under a covering. But does not the arrival of a stranger in a family imply more work? Are not the proofs of disinterested sympathy, the spirit of sacrifice in the women, the patience that long convalescence requires, worthy of note? It has been observed that, with the exception of some populated cities, hospitality has not really decreased since the arrival of the Spanish settlers in the New World. It distresses me to think that this change will happen as the colonial population and industry progress rapidly, and that the state of society that we have agreed to call advanced civilization might banish 'the ancient Castilian frankness'.

The Indians enter the caves once a year near midsummer with poles to destroy most of the nests. Several thousand birds are killed; the older ones hover over their heads to defend their young, screaming horribly. The young, called los pollos del guàcharo, fall to the ground and are cut open on the spot. Their peritoneum is loaded with fat; a layer of fat reaches from the abdomen to the anus, forming a kind of wad between the bird's legs. During this period, called the cosecha de la manteca (oil harvest) in Caripe, the Indians build palm-leaf huts near the entrance and in the cave vestibule itself. We could see their remains. With a brushwood fire they melt the fat of the young birds just killed and pour it into clay pots. This fat is known as butter or guàcharo oil; it is semi-liquid, clear and odorless, and so pure that it lasts for a year without going rancid. In the Caripe convent kitchen they only use fat from this cave, and the food never had a disagreeable taste or smell thanks to this fat.

After two days near the Atures cataract we were happy to load the canoe again and leave a place where the temperature was usually 29°C by day and 26°C at night. All day we were horribly tormented by mosquitoes and jejenes, tiny venomous flies (or simuliums), and all night by zancudos, another kind of mosquito feared even by the Indians. Our hands began to swell, and this swelling increased until we reached the banks of the Temi. The means found to escape these insects are often quite original. The kind missionary Father Zea, all his life tormented by mosquitoes, had built a small room near his church, up on a scaffolding of palm trunks, where you could breathe more freely. At night we climbed up a ladder to dry our plants and write our diary. The missionary had correctly observed that the insects preferred the lower levels, that is, from the ground up to some 15 feet. At Maypures the Indians leave their villages at night and sleep near the cataracts because the mosquitoes seem to avoid air loaded with vapors.

Between the mouths of the Padamo and the Mavaca the Orinoco receives the Ocamo from the north, into which flows the Matacona river. At the source of this last river live the Guainare Indians, far less copper-colored or brown than others in this region. This tribe belongs to what missionaries call 'fair Indians' or Indios blancos. Near the mouth of the Ocamo travelers are shown a rock that is the marvel. It is granite passing into gneiss, characterized by its black mica, which forms little ramified veins. Spaniards call this rock Piedra Mapaya (Map Rock). I chipped off a bit.
