a point arose about this is not poetry

[Brownlie]

Billy,

An Oak tree can only theoretically be like a poem, but if you write a poem and call it an oak tree, it is still not an oak tree because you have not written a poem to begin with.

Dale

You could cut down an actual oak tree, pulp it, make paper and then write a poem on the paper . . .

That would yield an interesting typographical analysis.
