Note 304 — Chapter IV
Reading edition
"It would seem as if the earliest known race of man inhabiting what is now British Central Africa was akin to the Bushman-Hottentot type of Negro. Rounded stones with a hole through the centre, similar to those which are used by the Bushmen in the south for weighting their digging-sticks, have been found at the south end of Lake Tanganyika. I have heard that other examples of these 'Bushman' stones have been found nearer to Lake Nyasa, etc." (British Central Africa, p. 52).
