In 1905, London purchased a ranch in Glen Ellen, Sonoma County, California, on the eastern slope of Sonoma Mountain. He wrote: "Next to my wife, the ranch is the dearest thing in the world to me." He desperately wanted the ranch to become a successful business enterprise. Writing, always a commercial enterprise with London, now became even more a means to an end: "I write for no other purpose than to add to the beauty that now belongs to me. I write a book for no other reason than to add three or four hundred acres to my magnificent estate."
