PIG. 17. The challeiig-e of forested hill lands to man has occurred throughout 

 the world. In many places man has won, and the hills serve him. In more 

 places the tormented hills have beaten man down, starved him, impoverished 

 him, and both hills and man are in a sorry state. Here, in Minnesota, man fairly 

 well has adjusted himself and his uses of land to the climate and topography 

 result: sustained production.
