RECIPROCITY BY J. LAURENCE LAUGHLIN, PH.D. AND H. PARKER WILLIS, PH.D. Professor of Economics and Political Science in Washington and NEW YORK: THE BAKER & TAYLOR CO. 33-37 EAST Seventeenth STREET, UNION SQ. NORTH PREFACE THE authors wish to express their appreciation of the courtesies extended to them by the officers of the Congressional Library at Washington, who have done what they could to place the resources of that collection at their disposal. Mention should be made of the help given by various members of the Treasury Bureau of Statistics, who have greatly forwarded the work of preparation through the assistance they rendered in granting the use of their statistical material, and in giving access to the library of the Bureau. Thanks are also due to many officers of the Government, who have lent or given needed documents. In addition, the authors especially desire to express their indebtedness to W. Jett Lauck, Esq., of Washington and Lee University, whose assistance in compiling statistics, preparing and digesting materials for use, and investigating special points has been invaluable. It goes without saying that not all the subjects of importance relating to Reciprocity could be included in a volume |
