Bituminous coal from II. C. Morris prospect, Interstate Investment Company, Crab 
Orchard. Loo County, \'a., about 7 miles from the Louisville and Nashville Railroad. 
This sample, which might be designated run-of-mine coal, was taken from a small pros- 
pect hole or country bank and was hauled in wagons, under the supervision of Inspector 
J. S. Burrows, to the railroad. It was used i,i making coking tests Nos. 64, 65, 67, 68i 
and 77, steaming tests Nos. 2M and 282, and producer-gas test No. 77. 
Three mine samples were taken for chemical analysis at this point. No. 2246 was cut 
from the entire seam of the left rib of the. drift, 29 feet from the outcrop; No. 2268 was 
cut from the lower bench at the face of the drift ; No. 2269 was cut from the upper bench
