ILLINOIS NO. 8. 
Bituminous coal from Paisley mine, Dering Coal Company, Paisley, Montgomery County, 
111., on the Big Four Railroad. 
This sample consisted of nut coal. It was shipped before the corps of inspectors was organ- 
ized, and consequently the loading of the car was not supervised by a representative of the 
plant. This sample was used in making steaming tests Nos. 101 and 102 and producer-gas 
test No. 29. 
No mine samples have as yet been taken from this mine, but before the final report of the 
testing plant is prepared the mine will be examined and the samples obtained.
