ACKNOWLEDGMENTS
The research reported in this dissertation would not have been
possible without the help of many individuals. Special appreciation
is due the officials of A. L. Mechling Barge Lines, Inc., and the
Central States Motor Freight Bureau, Inc. who so graciously supplied
data when other sources were lacking.
The staff of the Waterways Research Project at Northwestern
University, Professors R. B. Heflebower, L. B. Lave and R. H. Strotz,
provided advice and criticism at every stage of the research. Pro-
fessors A. P. Hurter and D. Mortensen were available for many helpful
comments and criticisms as the work progressed. The chairman of my
dissertation committee, Professor Leon N. Moses, is solely responsible
for my interest in transportation economics. His stimulating and con-
tinuing counsel was by far the most important factor in the completion
of this research. Finally, mention must be made of my colleague Joe
DeSalvo who has provided an almost daily sounding board for my ideas.
Of course none of the individuals cited above shares responsibility
for any remaining deficiencies.
Most of the calculations and data processing was performed by
George Sherling. Stina Hirsch typed many drafts of this dissertation
before Dottie Avakian made the final copy. To all of them, my thanks.
Finally, I am indebted to Northwestern University and to the
U.S. Army Corps of Engineers which sponsored the project from which
this dissertation developed.
