Please outline the way the poet describes the tree when she is at home and when abroad. Do you find the descriptions different?

Given the
nature of the poem, I think that the descriptions have to be different than one another.  The
reality is that the poem is one of nostalgia, a feeling in the present that the past's
significance is something missing in the modern setting.  The lens of nostalgia is what colors
the speaker's perception of the tree in the modern setting.  The description of the tree in
lands far off is significantly different than what was experienced because of the reality that
what is present now is a reality that is not able to encompass the meaning of the tree from the
past.  The tree's laments and cries of pain is what makes the tree different from then and now,
a description that embraces the nostalgic view of the tree and what it comes to represent to the
speaker.  In this, the tree's power and significance is one driven by the tendency of nostalgia
and the idea of how our past is something not to return.  The difference in descriptions also
bring to light how the elements in our present that can link us to our past are beyond precious
as they enable us to reach back into a period of time that has long since passed.  For the
speaker, the description of the tree's laments and cries are significant to the extent that the
tree will no longer be able to serve in the present the function it served in the past.  The
differences in description highlights the importance of nostalgia, a condition that makes life
in the present more bearable with the understanding of a past increasing in significance and
meaning.
