 Greeley's wife, however, found it shady and remote; at one point, the couple invited young Spiritualist Kate Fox to live with them for four months while they attempted to contact the spirit of their dead son through seances.The Greeleys were visited there by Henry David Thoreau, who shared Greeley's interest in land conservation.The "Tribune" published Thoreau's essay "The Succession of Forest Trees", after he and Greeley had an extensive discussion of forestry on one visit; the relationship continued to later years, when Greeley invited Thoreau to tutor the family's children.
