The Hovercraft arrives at Fort Lamy, capital of remote Tchad, to be met by the President. In the meantime a side expedition through the old African kingdom of Dahomey discovers a King and his female warriors - 'the Amazons of Abomey.'
From Fort Lamy the Hovercraft heads north along the Chari river to Lake Tchad, an inland sea as large as Wales and one of the least penetrated regions on earth.

Once a year in the highlands of New Guinea 20,000 warriors gather together in one place for the Sing-Sing, a huge government-organised display of tribal dancing, singing, and general high-jinks - kind of glorified agricultural show with natives in the ring instead of fat stock.
The warriors, probably the most primitive and certainly the most colourful on earth, spend two riotous days showing off their splendid feathers, wigs, and nose-bones to planeloads of tourists. The whole fantastic jamboree provides an instant microcosm of the colonial process - the breaking down of a traditional culture and the substitution of our own. It's at once riotously entertaining and sharply distressing.
