"Another editor. That thing behind his ear is his pencil. Whenever he finds a bright thing in your manuscript he strikes it out with that. That does him good, and makes him smile and show his teeth, the way he is doing in the picture. This one has just been striking out a smart thing, and now he is sitting there with his thumbs in his vest-holes, gloating. They are full of envy and malice, editors are."
—from “How to Make History Dates Stick,” an essay written by Twain in 1899, not published until after his death in Harper’s Monthly Magazine in December 1914. The essay was about using pictures as memory devices.
