From descriptions of trees that Henry David Thoreau noted in his journals. The journal entries are included in Thoreau and the Language of Trees, by Richard Higgins, which was published last month by the University of California Press.
A vast Corinthian column
A great green feather stuck in the ground
A harp upon which the wind makes music
A host that marches to victory over the earth
A traveler bending to the storm
A distant relation
Old citizen of the town
Handsome and cool and bosky
An athlete that shows its well-developed muscles
A fair, flaxen-haired sister with golden ringlets
A maiden that has taken the veil
A match found for me at last
