O. Henry,
McClure's Magazine, Volume 22, Number 6…
“ That is why the man who holds up trains picks his company with a thousand times the care with which a careful girl chooses a sweetheart. That is why he raises himself from his blanket of nights and listens to the tread of every horse's hoofs on the distant road. That is why he broods suspiciously for days upon a jesting remark or an unusual movement of a tried comrade, or the broken mutterings of his closest friend, sleeping by his side.And it is one of the reasons why the train-robbing profession is not so pleasant a one as either of its collateral branches—politics or cornering the market. ”
