Refuted claims regarding inspiration
Due to the enduring popular appeal of "Trees", several local communities and organizations across the United States have staked their claim to the genesis of the poem. While the accounts of family members and of documents firmly establish Mahwah being the place where Kilmer wrote the poem, several towns throughout the country have claimed that Kilmer wrote "Trees" while staying there or that a specific tree in their town inspired Kilmer's writing. Local tradition in Swanzey, New Hampshire, asserts without proof that Kilmer wrote the poem while summering in the town. Montague, Massachusetts, claims that either "a sprawling maple dominated the grounds near a hospital where Kilmer once was treated" or "a spreading maple in the yard of an old mansion" inspired the poem.
In New Brunswick, New Jersey, Kilmer's hometown, the claim involved a large white oak on the Cook College campus (now the School of Environmental and Biological Sciences), at Rutgers University. This tree, the "Kilmer Oak", was estimated to be over 300 years old. Because it had been weakened by age and disease, the Kilmer Oak was removed in 1963, and in reporting by The New York Times and other newspapers the local tradition was repeated with the claim that "Rutgers said it could not prove that Kilmer had been inspired by the oak." Currently, saplings from acorns of the historic tree are being grown at the site, throughout the Middlesex County and central New Jersey, as well as in major arboretums around the United States. The remains of the original Kilmer Oak are presently kept in storage at Rutgers University.
Because of Kilmer's close identification with Roman Catholicism and his correspondence with many priests and theologians, a tree located near a grotto dedicated to the Virgin Mary at the University of Notre Dame in South Bend, Indiana, has been asserted as the inspiration for the poem. According to Dorothy Corson, the claim was first made by a priest named Henry Kemper. There are several accounts that Kilmer visited the campus of Notre Dame to lecture and to visit friends, but none of these accounts or occasions date before 1914.
In his 1997 book of essays entitled The Geography of the Imagination, American writer Guy Davenport suggests a different inspiration for Kilmer's poem.
Trees were favorite symbols for Yeats, Frost, and even the young Pound. ... But Kilmer had been reading about trees in another context[,] the movement to stop child labor and set up nursery schools in slums. ... Margaret McMillan ... had the happy idea that a breath of fresh air and an intimate acquaintance with grass and trees were worth all the pencils and desks in the whole school system. ... The English word for gymnasium equipment is 'apparatus.' And in her book Labour and Childhood (1907) you will find this sentence: 'Apparatus can be made by fools, but only God can make a tree.'
It appears that Davenport must have loosely and erroneously paraphrased the sentiments expressed by McMillan, as this exact quote does not appear in her text. Instead, McMillan is expressing the observation that several nineteenth-century writers, including William Rankin, William Morris and Thomas Carlyle, opposed the effects of machinery on society and craftsmanship and thus eschewed machine-made items. Davenport's observation likely was derived in some way from McMillan's examination and quotation of Carlyle:
He (Carlyle) often makes comparisons between men and machines, and even trees and machines, greatly to the disadvantage of the latter. For example, 'O, that we could displace the machine god and put a man god in his place!' and 'I find no similitude of life so true as this of a tree! Beautiful! Machine of the universe!'
