The coal bed is very irregular and at no place was more than a few inches of coal visible, although it was confidently stated that the bed was 3 feet thick at the bottom of the pit, which had then caved. No trustworthy estimate of the true character of the bed can be obtained until the coal is found in place and in a normal position. It is reported that several prospects on Burnt Fork, farther...

Page 13 - In order to make determinations of the loosely held moisture more uniform and definite, a special drying oven has been designed and introduced into the laboratory. In this oven samples of several pounds weight can be dried in a gentle current of air, raised from 10° to 20° above the temperature of the laboratory. In this way the coal is...
