The Bororos made basket-work by plaiting dried palm-leaves, but their most interesting work of all consisted in the really beautifully made fishing nets. Nearly all the Indians of South America showed remarkable talent and patience at this work. The strings were twisted of a vegetable fibre, extremely resisting, and eminently suitable by its softness and regularity of diameter.

Whether owing to excitement, indigestion or other causes, the Bororos had visions, which they attributed to the Aroe Taurari. In a certain way they were believers in the transmigration of the soul—not generally, but in specific cases.

There were certain Bororos who, by magic songs, professed to fascinate animals in the forest and were able to catch them. The barih or medicine-man generally, assisted in those incantations.

The Bororos were remarkable walkers. They were extremely light on their feet and had a springy gait, most graceful to watch. A striking characteristic of these people was that, when standing—unlike nearly every other tribe of savages I have seen—they spread their toes outward instead of keeping both feet parallel. To a lesser extent the feet were held in that position also when walking. The suppleness of their bodies gave them a great advantage in penetrating with ease anywhere in the forest without having to cut their way through.

Both men and women were passionately fond of dancing, although their dancing had not reached any degree of perfection. With a strip of burity palm upon their shoulders they hopped around, monotonously chanting, with a rhythmic occasional jump, the women following the men.

The women possessed considerable endurance. They could carry heavy weights for long distances by means of a fibre headband resting on the forehead. Under those circumstances the body was kept slightly inclined forward. Children were also carried in a similar fashion in a sling, only—less practically than among many Asiatic and African tribes—the Bororo children were left to dangle their legs, thereby increasing the difficulty of carrying them, instead of sitting with legs astride across the mother's haunches. I was amazed to see until what age Bororo mothers and sisters would carry the young upon their shoulders—certainly children of five or six years of age were being carried about in this fashion, while such hard duties as pounding Indian corn, thrashing beans, and hut-building, were attended to.

Neither in women nor in men was the power of resistance in any way to be compared with that of the tribes of Central Africa or Asia. The Indian tribes of Brazil impressed one as being strong, because one compared them with their neighbours and masters, the Brazilians, who were physically one of the weakest, least-resisting races I have ever seen. When you compared them with some of the healthy savage races elsewhere, the Indians did not approach them in endurance and quickness of intellect. Do not forget that endurance is greatly due to brain power and self-control. The Indian races I saw in Brazil seemed to me almost exhausted physically, owing perhaps to constant intermarriage among themselves. The eyesight of the Bororos, for instance, was extremely bad. There were many in every aldeja who were almost or absolutely blind. The others were nearly all short-sighted.

The Bororos removed—pulled out, in fact—their eyelashes one by one, as they believed it improved their sight, especially for seeing at long distances. They all suffered more or less from complaints of the eyes. Indeed, I have seldom found races whose members had eyes in such poor condition. Conjunctivitis was the most prevalent form of eye disease. Ophthalmia was frequently met with. They seemed to have no efficacious method of curing those complaints, and the result was that one found an appalling number of blind or half-blind persons among them—quite out of proportion to the small population. The Bororos did not, of course, know of spectacles or any other way of protecting the eyes. Even when their eyes were in a normal condition, they nearly all had some defect of vision. Squinting was frequently to be noticed among them, and nearly invariably unevenness of the eyes. Cataract was common at a comparatively early age, and they knew no remedy for it. An abnormally marked discoloration of the upper part of the iris was constantly to be noticed even in young people. Among the healthiest I never saw one man or woman with extraordinary powers of vision such as are most common among savage tribes of Asia and Africa. The diseased condition of their blood was also perhaps to a certain extent responsible for this.

Their hearing was good, but not much more acute than with the average European—and infinitely inferior to that of the natives of Asia and Africa. They suffered considerably from the most terrible of blood complaints, general among them, also from leprosy and various skin troubles.

The Bororos made considerable use of the urucu plant (Bixa orellana L.) which they called nonoku, from the fruit of which they obtained a brilliant red colouring matter for tinting their bows and arrows. The shell of the fruit contained a number of shiny seeds, which, when squashed, exuded a vivid red juice. It adhered easily to the skin of the forehead and cheeks, for which purpose the Indians also extensively used it.
