Another thing that's quite different in writing a book as a practicing newspaperman is that if you look at what you've written the next morning and you think you didn't get it quite right you can fix it.
The pattern of a newspaperman's life is like the plot of 'Black Beauty.' Sometimes he finds a kind master who gives him a dry stall and an occasional bran mash in the form of a Christmas bonus sometimes he falls into the hands of a mean owner who drives him in spite of spavins and expects him to live on potato peelings.
