Excerpt from Coal: Part One, Coals of the Monongahela Formation or Upper Productive Coal Measures, Part Two, Chemical Analyses and Calorific Tests of the Clarion, Lower Kittanning, Middle Kittanning and Upper Freeport Coals<br><br>A feature of this part of the report is the new assignment made the Pomeroy seam. Heretofore that has always been regarded as the Pittsburg. But recent studies have demonstrated that the coal in question lies above the Pittsburg seam and is the equivalent of the Redstone of Pennsylvania and West Virginia. Credit for this determination belongs very largely to Mr. D. D. Condit.<br><br>Part Two consists of analyses and calorific tests of four seams of the Allegheny Formation or Lower Productive Coal Measures. These are the Clarion. Lower Kittanning, Middle Kittanning and Upper Freeport coals. Accompanying the results will be found sections showing the thickness and structure of the seam where sampled.<br><br>In the chapter by Professor Lord, Interpretation of the Chemical and Physical Tests on Coal, the value of coal as shown by its chemical. Analysis and the effects of the different constituents upon its fuel value are discussed in some detail, as are also the total and available heating values of coals.<br><br>About the Publisher<br><br>Forgotten Books publishes hundreds of thousands of rare and classic books.
