During a debate hosted by Davis Bradbury, Charles Fort talks about the evidence he has gathered of creatures from other worlds. Albert Wilmarth suggests that the reports are from people seeing ordinary objects and letting their imaginations run wild. Charles brings up that the descriptions of beings have been consistent across cultures. Albert notes that people used to believe in witchcraft, but everyone knows better now. He asks Charles if he has seen any of the creatures he writes about and Charles gets Albert to admit that he has never even been to Vermont to investigate the claims. Davis then ends the debate. Dean Hayes walks into the study room and says the local paper wants to take a photo of him, Charles and Albert. Charlie Tower then sends him away.
