COAL

By F. G. TRYON and L. MANN

INTRODUCTION

SPECIAL WORK BY COAL UNIT OF GEOLOGICAL SURVEY

With the publication of this report the continuous statistical record of coal production maintained by the United States Geological Survey reaches its forty-second year. The 1923 report, like its immediate predecessors, has been delayed by the pressure of other duties laid upon the Survey staff engaged in this work. Since the issue of the 1922 coal report the energies of the staff have been largely devoted to correcting and editing the report of the United States Coal Commission, the five volumes of which have recently appeared. The senior author of this chapter had been statistical adviser to the commission, and from January to July, 1925, the editing of the commission's studies absorbed most of his time. Further, the necessary proof reading made serious inroads on the regular work of his assistants. The sacrifice of the Survey's immediate interest was felt to be in the larger interest of the public and the coal industry. Opinions will differ as to the wisdom of the coal commission's recommendations, with which the authors of this chapter are not concerned, but there will be little dispute that the statistical studies of the commission form the most comprehensive source of data concerning the industry so far published. The fact that the Government had spent nearly $600,000 and the industry probably a much greater sum in preparing and tabulating the statistical schedules justified the greatest care in checking and correcting the tables and in so annotating and indexing them as to make the mass of material reasonably accessible.

For these reasons the present report appears many months late. In the meantime, however, the need of prompt publication of the fundamental figures has been met by releasing them as soon as completed in the Geological Survey's weekly coal report. In this way the principal statistics were made public in mimeographed form between September 1 and December 31, 1924.

ACKNOWLEDGMENTS

This report is based on the voluntary cooperation of those engaged in the coal industry, and it is a pleasure to acknowledge the courteous help of the thousands of individual producers, railroad officials, and consumers who have supplied information. Special mention should be made of the assistance of the secretaries of local coal operators' associations and the traffic managers of the principal coal railroads, who have not only assisted in collecting facts but have contributed much essential information through their familiarity with local conditions. The State geologists of Alabama, Illinois, Iowa, Georgia,

Maryland, Michigan, North Carolina, Virginia, and Washington; the State mine inspectors of Alabama, Indiana, Iowa, Kentucky, North Dakota, Tennessee, Texas, and West Virginia; the Pennsylvania State Department of Mines; the Department of Industrial Relations of Ohio; and the United States Bureau of Mines have cooperated in the collection of reports.

The compilation of the annual statistics of bituminous coal, the principal task underlying this report, was conducted by Miss L. Mann, of the United States Geological Survey, with the assistance of Miss J. M. Corse. The statistics of anthracite were compiled by Mrs. H. L. Bennit. The weekly and monthly estimates of production are prepared by Miss R. M. McKinney, under the supervision of W. F. McKenney. The canvass of wagon mines in 1923 and the tables of shipments by originating carriers were handled by Mrs. E. E. Finn under the supervision of Mr. McKenney. The tables of exports and imports were compiled by J. A. Dorsey from the records of the Bureau of Foreign and Domestic Commerce. F. G. Tryon was in charge of the work and in collaboration with L. Mann wrote the text of this report.

The manuscript and proof have been critically reviewed by James E. Black, to whom the authors are deeply indebted.

STATISTICAL SUMMARY OF COAL MINING IN 1923 SALIENT FEATURES

The salient features of the statistics of coal mining in 1923 for the United States as a whole are given in Table 1. Table 2 gives the primary data by States, with comparable figures for 1921 and 1922. Table 3 is a summary of production and consumption for the 11-year period 1913 to 1923.
