"King Spruce" is personified in John Barrett, lumber magnate of the North woods. His domineering character is shown when his daughter Elva falls in love with a school teacher, Dwight Wade. Barrett conspires with his foreman, McLeod, to entice Wade away to the lumber camps, and finally decides to accompany the gang of men himself. He starts in to eject and burn out all "skeeters" who have settled on the land without domiciliary rights. Wade has shown his fighting blood by thrashing McLeod for an act of cruelty, and he now vainly opposes Barrett from motives of humanity. From the first shack burned emerges a wild girl, Kate Arden, who sets the forest afire in revenge.
