How to detect a forger as one of the cleverest of operating criminals
has been solved by the "thumb print" method of identification now
spreading through the rogues' galleries of the world.
It is quite as interesting as the suggestion that through the same
thumb print method in commercial and banking houses the forger is
likely to become a creature without occupation and chirographical or
other means of support.
The system is not only a great aid in preventing the forgeries of
commercial brigands, but the easiest of all means for a person in a
strange city to identify himself as the lawful possessor of check, or
note, or bank draft which he may wish to turn into cash at a banker's
window.
