(M118) The Guarayos Indians, who inhabit the gloomy tropical forests of Eastern Bolivia, lift up their children in the air at new moon in order that they may grow.(394) Among the Apinagos Indians, on the Tocantins River in Brazil, the French traveller Castelnau witnessed a remarkable dance by moonlight. The Indians danced in two long ranks which faced each other, the women on one side, the men on the other. Between the two ranks of dancers blazed a great fire. The men were painted in brilliant colours, and for the most part wore white or red skull-caps made of maize-flour and resin. Their dancing was very monotonous and consisted of a jerky movement of the body, while the dancer advanced first one leg and then the other. This dance they accompanied with a melancholy song, striking the ground with their weapons. Opposite them the women, naked and unpainted, stood in a single rank, their bodies bent slightly forward, their knees pressed together, their arms swinging in measured time, now forward, now backward, so as to join hands. A remarkable figure in the dance was a personage painted scarlet all over, who held in his hand a rattle composed of a gourd full of pebbles. From time to time he leaped across the great fire which burned between the men and the women. Then he would run rapidly in front of the women, stopping now and then before one or other and performing a series of strange gambols, while he shook his rattle violently. Sometimes he would sink with one knee to the ground, and then suddenly throw himself backward. Altogether the agility and endurance which he displayed were remarkable. This dance lasted for hours. When a woman was tired out she withdrew, and her place was taken by another; but the same men danced the monotonous dance all night. Towards midnight the moon attained the zenith and flooded the scene with her bright rays. A change now took place in the dance. A long line of men and women advanced to the fire between the ranks of the dancers. Each of them held one end of a hammock in which lay a new-born infant, whose squalls could be heard. These babes were now to be presented by their parents to the moon. On reaching the end of the line each couple swung the hammock, accompanying the movement by a chant, which all the Indians sang in chorus. The song seemed to consist of three words, repeated over and over again. Soon a shrill voice was heard, and a hideous old hag, like a skeleton, appeared with her arms raised above her head. She went round and round the assembly several times, then disappeared in silence. While she was present, the scarlet dancer with the rattle bounded about more furiously than ever, stopping only for a moment while he passed in front of the line of women. His body was contracted and bent towards them, and described an undulatory movement like that of a worm writhing. He shook his rattle violently, as if he would fain kindle in the women the fire which burned in himself.
