Mr. Henry Miller,
18 Villa Seurat,
Paris xiv, France.
Dear Mr. Miller:
I am sorry to say that I had to turn down BLACK SPRING. I admire your talent for writing, but I didn't like this particular book at all. In my opinion, it hasn't the faintest chance of achieving commercial success in America. I hope, for your sake, some other publisher thinks differently about the book and that I turn out to be all wrong about it.
It wouldn't be the first time!
Cordially,
(Signed)
Bennett A. Cerf

File or throw away?
A lukewarm prick!
Henry.
