There is much discussion these days about the health
of the magazine business. Rising costs for printing, paper,
and postage threaten to crimp already struggling budgets
past their limits. And periodically, too, a major publica-
tion dies, adding to the rumors that the whole industry is
dying, a thing of the past.
  In the midst of this turmoil, the Wisconsin Academy
Review, with this issue, completes Volume 20. And now,
just as in 1954 when Volume 1 was published, we depend
heavily upon the generosity of many people to "make ends
meet. "
  For example, thirteen authors have contributed their
time and expertise to provide the manuscripts which are
found on these thirty-two pages. None of them has re-
ceived anything more than our hearty thanks and a few
copies of the magazine. The Escher Foundation kindly
waived the traditional reproduction rights fees for the two
M. C. Escher prints found on pages 2 and 5. And on pages
7, 9, and 11 are illustrations by Chris Sternberg, whose
services I am sure we will be requesting again.,
  Readers who have suggestions for stories they would like
to see included in the Review or manuscripts they would
like to have considered for publication should feel free to
contact me. With the continued support of Wisconsin
writers, artists, and readers, you can be assured that the
Wisconsin Academy Review is indeed alive and well.
