Their children from the age of three or four must work in the fields. The death rate of their babies is among the highest in the world, their standards of education among the lowest. They live at heights of ten or fifteen thousand feet, where even the air lacks the things necessary for life.
The needs of these Indians, scattered across three countries — Ecuador, Peru and Bolivia—are great. Their problems are difficult and their diseases are deeply rooted in an old-fashioned way of life.
