Kerouac: ...the prose in "October in the Railroad Earth," very experimental, intended to clack along all the way like a steam engine pulling a one-hundred-car freight with a talky caboose at the end, that was my way at the time and it still can be done if the thinking during the swift writing is confessional and pure and all excited with the life of it. And be sure of this, I spent my entire youth writing slowly with revisions and endless rehashing speculation and deleting and got so I was writing one sentence a day and the sentence had no FEELING. Goddamn it, FEELING is what I like in art, not CRAFTINESS and the hiding of feelings.
