In the Tropics on those days when the earth is shaken by violent shocks the regularity of the barometer is not disturbed. I have verified this observation at Cumana, at Lima and at Riobamba. Scientific observers should note this, for on Santo Domingo, in the town of Cape Francois, it has been asserted that a water barometer sank 2. inches just before the earthquake of 1770. It has also been related that a chemist, at the time of Oran's destruction, fled with his family a few minutes before the earthquake because he had noticed that the mercury in his barometer had sunk in an extraordinary manner. I do not know whether to believe his story. But as it is practically impossible to examine the variations of the weight of the atmosphere during the shocks, we must be satisfied with observing the barometer before and after.

The tribes of the Upper Orinoco, the Atabapo and the Inirida, worship only the forces of nature. The principle of good is called Cachimana; it is the manitu, the great spirit, that controls the seasons and ripens fruit. Next to Cachimana there is the principle of evil, Jolokiamo, less powerful but more astute and, especially, more dynamic. When the jungle Indians go to missions it is difficult for them to conceive of a church or an image. 'These good people, said our missionary, 'like only outdoor processions. Recently when I celebrated the village's saint's day the Inirida Indians came to mass. They told me: Your god is locked into a house as if he was old and sick; our god is in the jungle, in fields, in the Sipapu mountains from where the rains come. In the larger, and thus more barbarous tribes, peculiar religious societies are formed. Some of the older Indians claim to be better initiated in divine matters and guard the famous botuto that they play under palm trees to make the fruit ripen. On the Orinoco banks no images or idols can be found, but the botuto, the sacred trumpet, is worshipped. To be initiated into the mysteries of the botuto you must be pure and celibate. The initiated are subject to flagellations, fasting and other disciplinarian practices. There are few sacred trumpets. The most famous is found on a hill at the confluence of the Tomo and Guainia rivers. It is said it can be heard at a distance of 10 leagues. Father Cerezo assured us that Indians talk of this botuto as the object of a cult common to several neighboring tribes. Fruit and alcoholic drinks are placed round this sacred trumpet. Sometimes the great spirit Cachimana himself blows the botuto, sometimes he speaks through whoever guards the instrument. As these tricks are very ancient (the fathers of our fathers, the Indians say) you should not be surprised that there are many believers. Women are not allowed to see the marvelous trumpet, and are excluded from all religious service. If one has the misfortune to see it she is mercilessly killed. The missionary told us that in 1798 he was lucky enough to save a young girl whom a jealous lover had accused of having followed the Indians who sounded the botuto. 'They would have murdered her publicly, said Father Cerezo. 'How could she have protected herself from Indian fanaticism, in a country where it is so easy to be poisoned? I sent her away to one of the missions on the Lower Orinoco.
