Bullock, Ph.D., Assistant Professor of Economics, Harvard University ECONOMIC HISTORY OF THE UNITED By Guy Stevens Callender, Professor of Political PREFACE This volume aims to supply the collateral reading needed for a general course of study in economics. It makes no effort to present selections upon all the topics treated in such a course, but endeavors merely to provide supplementary material, historical, descriptive, and theoretical, which will enrich the instruction offered. The footnotes to the several selections disclose the extent of the editor's indebtedness to various authors who have consented to the reproduction of passages from their works. In this place, however, acknowledgment should be made of the helpful advice and criticism received from the editor's colleague, Professor F. W. Taussig, of Harvard University. CHARLES J. BULLOCK |
