Breeze produced do 2.96 
Total percentage yield 67. 81 
Remarks.— Light gray. Hard heavy coke. 
High yield due to deposited carbon. 
Test 65, Virginia No. 1.

Coke produced per cent . . .68. 11 
Breeze produced do 2.58 
Total percentage yield 70. 69 
Remarks.— Light gray and silvery. Good 
heavy coke. High yield due to deposited carbon. 
Test 67, Virginia No. 1. 
Size as shipped, run of mine. Size as used, not 
crushed. Raw. Duration of test, 36 hours. 
Coal charged pounds . . 10, 000 
Coke produced do 5, 879 
Breeze produced do 424 
Coke produced per cent . . 58. 79 
Breeze produced do 4. 24 
Total percentage yield 63. 03 
Remarks.— Light gray and silvery. Coke not so 
good as that from ground charge. Cross breakage 
increased and breeze much larger, but good coke. 
Results would justify installation of disintegrat- 
ing machinery. High yield due to deposited 
carbon.

Remarks.— Light gray and silvery. Large per- 
centage of breeze due to not grinding coal before 
charging. Loss by breakage also increased from 
same cause. Good hard heavy coke. High yield 
due to deposited carbon.

VIRGINIA NO. 3. 
Bituminous coal from the "big opening" on Wilson farm, Interstate Investment Com- 
pany, near Crab Orchard, Lee County, Va., about 7 miles from the Louisville and Nashville 
Railroad. 
This sample, which was run of mine, was loaded in wagons and hauled to the railroad 
under the supervision of Inspector J. S. Burrows. It was used for washing test No. 134, 
coking tests Nos. 63, 69, and 70; steaming tests Nos. 247, 251, 256, and 258, steaming 
i test on washed coal No. 260, and producer-gas test No. 78. 
Two mine samples were taken in this opening for chemical analysis. No. 2248 was 
taken from the upper bench at the face of the opening, 75 feet from the outcrop; No. 2249 
was taken from the lower bench at the same location.
