Note 825 — Chapter XVII · THE ORIGIN OF PERPETUAL FIRES
Reading edition
Sir Harry H. Johnston, ll.cc. Professor K. von den Steinen conjectures that savages, who already possessed fire, and were wont to use tinder to nurse a smouldering brand into a blaze, may have accidentally discovered the mode of kindling fire in an attempt to make tinder by rubbing two dry sticks or reeds against each other. See K. von den Steinen, Unter den Naturvölkern Zentral-Brasiliens, pp. 219-228.
