If America does not occupy an important place in the history of mankind, and in the revolutions that have shattered the world, it does offer a wide field for a naturalist. Nowhere else does nature so vividly suggest general ideas on the cause of events, and their mutual interrelationships. I do not mean by this solely the overpowering vegetation and freshness of organic life, the different climates we experience as we climb the cordilleras and navigate those immense rivers, but also the geology and natural history of an unknown continent. A traveler can count himself lucky if he has taken advantage of his travels by adding new facts to the mass of those previously discovered!

Our interpreters could give us no details about the age of these baskets and vessels. However, the majority of the skeletons did not seem to be more than a hundred years old. Among the Guareca Indians there is a legend that the brave Atures, chased by the cannibalistic Caribs, hid in the cataract rocks, where they died out, leaving no trace of their language. The last survivor of the Atures could not have lasted much longer, for at Maypures you can still see an old parrot that 'nobody understands because', so the Indians say, 'it speaks the language of the Atures'.

This Brazil-nut tree is usually not more than 2 to 3 feet in diameter, but reaches up to 520 feet in height. The fruit ripens at the end of May and, as they are as big as a child's head, make a lot of noise when they fall from so high up. I usually found between fifteen and twenty-two nuts in one fruit. The taste is very agreeable when the nuts are fresh; but its copious oil - its main use - quickly goes rancid. In the Upper Orinoco we often ate quantities of these nuts for want of food, and no harm came to us. According to trustworthy Indians only small rodents can break into this fruit, thanks to their teeth and incredible tenacity. But once the fruit have fallen to the ground all kinds of jungle animals rush to the spot: monkeys, manaviris, squirrels, cavies, parrots and macaws fight over the booty. All are strong enough to break the woody seed case, pick out the nut and climb back up the trees. 'They too have their fiestas, the Indians say as they return from the harvest To hear them complain about these animals you would think that the Indians alone are masters of the jungle.
