  <dc:description>&lt;p&gt;This report is part of a continuing program by the U.S. Geological Survey, State Geological Surveys, and the Coal Analysis Section of the&lt;br&gt;U.S. Department of Energy to provide chemical data on the composition of important coal beds of the United States of America. Such data are useful in determining the economic value of a coal, environmental effects of coal mining and coal use, and the adaptability of a coal to cleaning and to other technological processes of coal treatment and usage.&lt;/p&gt;</dc:description>
