Paperback. Etat : New. Print on Demand. This book compiles reports on coal and lignite fields in the United States at the beginning of the 20th century. It includes detailed stratigraphic sections and chemical analyses of the mined coal, providing a valuable dataset for understanding the composition and distribution of coal in the USA during that time period. It also examines the value of lignite as fuel for steam and gas plants, revealing that it can be used in producer-gas plants to generate more energy than the best coal of the era could in a steam plant. The context of the book is the United States Geological Surveyâs classifying and valuing public land. The author traveled extensively, and his description of the various coalfields he visited provides a valuable historical record of these natural resources at that time. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
