Heating Power Of Wyoming Coal PDF Download

Excerpt from The Heating Power of Wyoming Coal and Oil: With a Description of the Bomb Calorimeter Collection Of Samples. The most essential part of an investigation like the present is the selection of samples accurately representing the coal fields from which they are taken. This task was efficiently performed by W. C. Knight, Professor of Geology in the University of Wyoming, who personally visited most of the coal- and oil-fields of the State during the summers of 1893 and 1894. The samples were obtained by cutting down the whole face of the exposed coal-bed, rejecting partings and slates, breaking up and dividing until a sample of five to ten pounds weight was obtained. This was shipped to the University, where it was powdered and sampled for analysis. The samples since their preparation have been preserved in glass-stoppered bottles, and it is believed that they have not materially lost in water content. Samples not selected by Prof. Knight were usually taken, by the owner or someone connected with the management and are indicated by the letter O; for them, of course, the University assumes no responsibility, although there is no reason to doubt the fairness of the selection. If any important coal-mines have been omitted from this investigation it is not the fault of the University, as announcements of the work in progress and requests for samples have been often published during the past two years.
