There is surely not anything wonderful here. Tired of hearing Eben complaining, his father challenges him to really look around him. If he can find seven wonders in Sassafras Springs in one week, his father will buy him a train ticket to visit relatives in Colorado. But this is Sassafras Springs! There is no way Eben will find anything unusual here. Or is he just not looking hard enough?
