Book Description
Excerpt from Coal Mining: Described and Illustrated The Almighty in His great bounty has provided for all our wants in endless abundance and variety. In some parts of the Tropics, when the rainy seasons come to moisten the ground which has been baked by the heat of the sun, you can see the vegetation thrust out of it by a powerful influence. The transformation which takes place is truly magical. Within a few weeks, the ground that was bare supports masses of vegetable matter so high and so rank as to forbid one's passage through them. Year succeeds year and each contributes its layer of vegetation, which is generously supplied with carbon, oxygen, hydrogen, nitrogen, and traces of other important ingredients which combine to form those wonderful products of nature. But, alas! After the rains cease to moisten the earth, the sun shines hotly through the thirsty atmosphere and abstracts the moisture from the vegetation which has been so generously nourished by it. In a short time only a portion of the whole remains; the bulk of the ingredients passes back into the winds again, and is carried by them to other parts of the globe perhaps to make component parts in the construction of other vegetable or animal organisms.

Book Description
Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

Book Description
Excerpt from The Coal Mines: Containing a Description of the Various Systems of Working and Ventilating Mines, Together With a Sketch of the Principal Coal Regions of the Globe, Including Statistics of the Coal Production Most of the matter composing the following pages was prepared for publi cation two years ago, but, on my appointment to the office of Mine Inspector of the State, the work was laid aside for want of time to complete it. It is now offered to the public in its present form in the hope that it will in some degree supply a want long felt by practical men in the United States. I am aware that the work is both too brief and imperfect, but hope its publication may induce some one more competent to prepare a more elaborate volume on the subject. The business of coal mining will continue to be, for several centu ries to come, the main industry of our country, for coal is the main-spring of modern civilization. Less is known, because less is written, on underground coal mining than on any other subject. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
