To Ezra Pound
With much friendship and admiration and some differences of opinion
The Poet took his walking-stick
Of fine and polished ebony.
Set in the close-grained wood
Melissa Bradshaw points out that Pound was not only a useful foil for Lowell, but a useful marketing device: 
 …it very publicly disavows any sympathies with an increasingly elitist Pound, while on the other,it memorializes (cashes in on?) their brief alliance. […] Lowell has an investment in Pound as a forbidding, menacing arbiter of high culture. Next to him, she comes off as a reasonable, fair, benevolent leader in the new poetry movement. While Pound and Eliot’s writings become more and more elitist with their return to classical meters and allusions, aimed at an educated, multi-lingual audience, Lowell carves a niche for herself as introducing poetry to “people with a spark of poetry in them, be they blacksmiths or millionaires.”  – -  
 In other words, Pound used Lowell to define his own idea of what poetry should be (masculine, elitist, “hard”)…but she used him right back.
