ACROSS UNKNOWN SOUTH AMERICA 
lines for the body, legs, and arms, and a dot for the head 
— were extraordinary because they represented the body 
and limbs covered with hair, done simply by minor parallel 
lines. I asked the Mundurucus why they represented 
human beings with hair, whereas they themselves were 
hairless on the body and face. They said it was because in 
ancient times all the people were hairy, like monkeys. 
I was strongly impressed by the difference in type

in contact with the Apiacars, another tribe of Indians

it gave me a great deal of pain I never for one moment

knocked down the tree, as usual, to get the chestnuts, 
although it was fully three feet in diameter. They picked 
a great many of the wild chestnuts and proceeded to
