By this point, there is no real reason to believe Messinger’s geographical calculations, but no one else has a better idea, so the canoe plan goes ahead. He and Tony, of course, don’t take part in the arduous construction. Messinger’s ignorance will not be reasoned with by any amount of Macushi explanation. Unfortunately for him, this means that he has hit a brick wall: he has no leverage on Rosa and the Macushi, only some novelty goods that they would like but can easily live without.
