In writing a letter, for example, the pen scope through it may show an
average stretch of one inch for the text of the letter, while in the
signature the whole length of the signature twice as long, may be
covered. But if the writer covers this full stretch of his name in
this way the expert may prove by the necessary short pen scope of the
copyist that the studied copy is a forgery on its face. For however
free of pen stroke the forger may be naturally, his attempts to
produce a facsimile of the signature shortens it beyond the scope of
the original signer.

If a search be made through a series of undisputedly genuine
signatures, it will be found that one characteristic fails in one and
another in another. Here is where the handwriting expert makes his
service valuable. He studies all these important points, and is not
long in arriving at a successful conclusion.

The introduction of the experimental method into all modern
investigation has led to the hope that in this difficult subject means
will be found to introduce simpler forms of determining regular or
irregular handwriting.

As long as the steps by which experts reach their conclusions are so
intricate or recondite that only the results may be stated to the
jury, just so long will the character of expert testimony suffer in
the opinion of the public, and the insulting charge against it be
repeated that any side can hire an expert to support its case.

If a single competent expert could be selected by the court to take up
questions of this kind and lay his results before it, the present
system would be less objectionable than it is. Nevertheless, this
