ILLINOIS NO. 7. 
Bituminous coal from mine No. 2, Lumaghi Coal Company, near Collinsville, Madison 
County, 111., on the Vandalia Railroad. 
Four lots of coal were shipped for testing from this mine. One consisted of slack which 
had been passed through a 1-inch mesh screen; this lot is designated as Illinois No. 7 A 
and was used in making producer test No. 26. Sample Illinois No. 7 B consisted of nut 
coal which had passed over a 1-inch mesh screen and was used in making producer-gas 
test No. 27. These two lots were shipped under the supervision of Inspector J. S. Burrows. 
Sample Illinois No. 7 C consisted of another car of slack, which was used in making washing 
test No. 104, steaming test No. 122, steaming test on washed coal No. 129, and producer-gas 
test No. 38. This car was not inspected, as it was slack coal. Sample Illinois No. 7 D 
consisted of run-of-mine coal and was shipped under the supervision of Inspector J. W. 
Groves. It was used in making washing test No. 108, coking tests Nos. 1 and 4, and 
steaming tests Nos. 142, 143, and 146. 
Two mine samples were collected in this mine for chemical analysis. No. 1608 was 
taken at the face of room 17, north entry, and No. 1609 at the face of room 14, south
