UNITED STATES DEPARTMENT OF THE INTERIOR J. A. KRUG, Secretary BUREAU OF MINES JAMES BOYD, Director UNITED STATES GOVERNMENT PRINTING OFFICE WASHINGTON: 1948 For sale by the Superintendent of Documents, U. S. Government Printing Office, Washington 25, D. C. Price $3.75 DEPOSITED BY THE UNITED STATES OF AMERICA NOV 1 1'48 FOREWORD This annual publication of the Bureau of Mines is more than a mere compilation of economic and statistical information. It is a measure of the basic strength of the Nation's industrial structure, for the ebb and flow of mineral commodities through a country's economic arteries are reliable indications of its industrial vigor and progress. The year 1946, the first postwar year, was a time of transition-a period of reconversion-when the inordinate requirements of war gave way to the pent-up demands of domestic consumers. This changeover from a wartime to a peacetime economy is reflected in the statistics presented in each of the individual commodity chapters. The Minerals Yearbook for 1946 chronicles in detail this first year of transition and provides information which is of value to America's businessmen, labor leaders, educators, Government executives and legislators, and others who share in charting our national course. The Bureau of Mines deeply appreciates the assistance of the minerals industry in providing information for this volume and also wishes to acknowledge the help of the many State geologists who cooperated in compiling production data.
