character as to be easily simulated, detection is ofttimes difficult,
and expert demonstrations less certain or convincing. Yet instances
are rare in which the forger of even a signature does not leave some
unconscious traces that will betray him to the ordinary expert, while
in most instances forgery will be at once so apparent to an expert as
to admit of a demonstration more trustworthy and convincing to court
and jury than is the testimony of witnesses to alleged facts, who may
be deceived, or even lie. The unconscious tracks of the forger,
however, cannot be bribed or made to lie, and they often speak in a
language so unmistakable as to utterly defy controversion.

With the present-day knowledge of writing in its various phases, the
identity of forged, fraudulent or simulated writing can be determined
beyond the possibility of a mistake. Every year sees an increase in
the number of important civil and criminal cases that turn on
questions of disputed handwriting.

There is not a day in the year but what bank officials are at sea over
a disputed signature and a knowledge of how to test and determine
genuine and forged signatures will prove of inestimable value to the
banking and business world.

Forgery is easy. Detection is difficult. As the rewards for the
successful forgers are great, thousands upon thousands of forged
checks, notes, drafts, wills, deeds, receipts and all kinds of
commercial papers are produced in the United States every year. Many
are litigated, but many more are never discovered.
