The poems changed. I also had taken a lot of the criticism of Exiles and Marriages to heart and was writing some poems which were sort of the antitheses of them. I wrote a second book rather quickly... it came out three years after the first. My first book came out in 1955, my second in 1958. It was called The Dark Houses. It was a book of my father's death in considerable part, and it was also a book that began to reach toward the... the irrational, the almost surreal, the fantastic, but much more of that came in my third book which I believe was 1963, A Roof of Tiger Lilies.  Again there was some mixture there. But all the time I was working on the poems, everything was concentrated on the writing. When I was in the classroom, I was totally there - I made my office hours  - and I corrected it, but there was no question but that I was living to write. After the first two years of teaching, I thought, oh wow, two years of work in a row! I gotta get some time off. You know, I knew I was a little spoilt, but maybe somebody would keep on spoiling me. I applied for Guggenheim, and I didn't get it.  And oh, later the guy who ran the Guggenheim told me, 'Well we thought you'd been doing rather well'.  And I had made a little money writing, and one or two poetry readings - poetry readings were just beginning - and it was amazing when the phone rang one day, and somebody said he was an agent, and he wanted to recommend me for... represent me for poetry readings.  I didn't believe it.  And I thought it was a fad - it'll be gone in a year or two.  But there are more poetry readings every year, you know.  And so I would fly out of Detroit, and do a reading and come home, not missing classes, and get $500, so I'd saved up something like $2000, $2500, and I decided to take leave without pay from the university.  That's another attraction to the possible situation at a university - if you want to take time off, you are very replacable - you are a replacable unit.
