Albert Bigelow Paine,
The Boys' Life of Mark Twain — Chapter 53
(1916)
“ What Henry Rogers did give to Mark Twain was his priceless counsel and time—gifts more precious than any mere sum of money—favors that Mark Twain could accept without humiliation. He did accept them, and never ceased to be grateful. He rarely wrote without expressing his gratitude, and we get the size of Mark Twain's obligation when in one letter we read: I have abundant peace of mind again no sense of burden. ”
