In an interview from 1960, Robert Frost told the Paris Review about his trip to England in 1912:
What were the circumstances of your meeting [Ezra] Pound when you were in England?
That was through Frank Flint. The early Imagist and translator. He was a friend of Pound and belonged in that little group there. He met me in a bookstore, said, “American?” And I said, “Yes. How’d you know?” He said, “Shoes.” It was the Poetry Bookshop, Harold Monro’s, just being organized. He said, “Poetry?” And I said, “I accept the omen.” Then he said, “You should know your fellow countryman, Ezra Pound.” And I said, “I’ve never heard of him.” And I hadn’t. I’d been skipping literary magazines—I don’t ever read them very much—and the gossip, you know, I never paid much attention to. So Ezra Pound friend Frank Flint] said, “I’m going to tell him you’re here.” And I had a card from Pound afterwards. I didn’t use it for two or three months after that. …I didn’t like the card very well.
What did he say on it?
Just said, “At home, sometimes.” Just like Pound. So I didn’t feel that that was a very warm invitation.
