We saw the Indians dancing. These dances are all the more monotonous as women do not dare take part. The men, both young and old, hold hands, form a circle, and for hours turn around to the right, then the left, in utter silence. Usually the dancers themselves are the musicians. Weak notes blown from reeds of different sizes make it all seem slow and sad. To mark the time the leading dancer bends both knees rhythmically. The reeds are tied together in rows. We were surprised to see how quickly young Indians could cut reeds and tune them as flutes when they found them on the banks.
