I have found a mention of an article my grandmother wrote, but have
not been able to locate the exact citation.  Information is listed
below.  You do not need to find the full text, just enough information
that I can request it by interlibrary loan.

Title is unknown, but article is about waitressing.
Published 1922 or earlier (probably not much earlier).
Author could be "Barry Fox" or "Helen Mildred Fox" (she changed her name).
Published in "Liberty Magazine" (or possibly "Liberty" magazine).
[Note: I tried to research this a bit, and found that there were a lot
of periodicals in this time period titled "Liberty" or some variation
of that.]
