The Duck, its powers augmented by the negative energy of the line and obsessed with a decoy the party have created and placed upon it, becomes a permanent resident of it. Dixon meanwhile becomes obsessed with infinite westward expansion, and the party approaches the Monongahela River. Meanwhile, two "axmen" are killed by a falling tree. A wide variety of Indian nations take an interest in the party as it passes through their lands, where the surveyors eventually travel upon the "Warrior-Path" amid feuding war-parties. Lastly, Mason & Dixon share a dream of pursuing their path further west.
