“ The old town, to which place we dropped down to breakfast, has one hundred and twenty inhabitants, of which twenty-five are white, and the rest Indians of the Yavari, called Marubos. These are dressed with even more simplicity than the Yaguas, dispensing with the mop behind. They have small, curly moustaches and beards; are darker than the other Indians; and do nothing but hunt for their living. ”
