inclined to agree it is not a stork but has no clue what it really is, until a night-time encounter when it flies down and is seen by all at close range, as it steals the companions' dinner. After this, Summerlee apologises to Challenger. The cliffs to the plateau itself prove to be apparently unscalable, but an adjacent pinnacle turns out to be climbable, and moreover, has a tall tree which can be cut down and used as a bridge, which allows the four explorers to cross to the plateau. However, they are almost immediately trapped on it, thanks to the treachery of one of their luggage-porters, Gomez: who, as it turns out, is a former slaver whose brother had previously been killed by Roxton during his anti-slavery activities. Gomez takes his revenge by dropping the tree off the cliff, stranding the explorers on the plateau. Roxton shoots Gomez and they hear the scream and then the thud of the falling body.

After witnessing the power of their guns, the tribe wish to keep them on the plateau but, helped by the young prince they saved, they eventually discover a tunnel leading back to the outside world. During their time with the tribe,
