COKTNCJ TESTS. 39 
Indiana No. 17. — Test 163: Dark-gray color; breakage, large pieces of irregular size* 
cell structure large; ash and sulphur high. 
Indiana No. 18 A. — Test 158: No coke produced; ashed down about 3 inches, and blaze 
lost. 
Test 168: No coke produced. 
Kansas No. 6. — Test 113: Light-gray color, some silvery coloration; cell structure good; 
breakage good; long, large, heavy pieces; heavy clinker over whole surface of 
coke; ash and sulphur high; washing would probably reduce ash very materially, 
and produce better grade of coke. 
Test 115: Light-gray and silvery color; metallic ring; breakage good ; long, large, 
heavy pieces; cell structure good; strong heavy coke; washing reduces ash and 
sulphur, but both still high. 
Kentucky No. 1 B. — Test 76: Light-gray and silvery color; much deposited carbon; 
metallic ring; cell structure good; a fine-fingered coke; breakage bad, brittle. 
Kentucky No. 1 C. — Test 71: Light-gray and silvery color; metallic ring; cell structure 
a little large; breakage, long, thin-fingered pieces; good coke, but very brittle. 
Kentucky No. 5. — Test 75: Light-gray and silvery color; much deposited carbon; 
metallic ring; cell structure good; breakage bad, very brittle. 
Kentucky No. 6. — Test 86: Light-gray and silvery color; metallic ring; cell structure 
small; breakage, long, fine-fingered pieces, very brittle. 
Test 90: Light-gray and silvery color; metallic ring; cell structure small; breakage 
bad, brittle; fine-fingered coke. 
Kentucky No. 7. — Test 85: Light-gray and silvery color; metallic ring; cell structure 
good; breakage good; long, large pieces; coke contains a large amount of hard 
clinker on top and through cracks; good weight coke; ash and sulphur high. 
Kentucky No. 8. — Test 164: Dark-gray color, with some little silvery deposit of car- 
bon; cell structure large; breakage good; regular-sized pieces. 
Test 165: Light-gray color; breakage good; large pieces of regular size; cell struc- 
ture a little large; some little improvement over test No. 164. 
Kentucky No. 9 A. — Test 167 : Light-gray color, with black top and some silvery deposit 
of carbon; cell structure good; breakage, long-fingered pieces; sulphur high. 
Maryland No. 1. — Tests 50, 54: No coke produced. 
Test 58 (with 10. per cent pitch): Dull-gray color; cell structure small; breakage, 
large and small chunks; poor, soft coke. 
Missouri No. 5. — Test 116: Light-gray and silvery color; cell structure good ; breakage 
somewhat cross fractured but pieces of good, large size; good weight coke; ash 
and sulphur high. 
New Mexico No. 3 B. — Test 148: Light-gray color, some silvery deposit of carbon; 
metallic ring; cell structure medium; breakage good; long, large pieces; good, 
heavy coke, but ash high. 
Test 149: Light-gray color; some silvery deposit of carbon; metallic ring; cell 
structure medium; breakage good; long, large pieces; good, heavy coke; ash 
reduced by washing, but still high. 
New Mexico Nos. 3 B, 4 B. and 5.— Test 152: Light-gray and silvery color; metallic 
ring; cell structure good ; breakage good ; long, large pieces; good, strong, heavy 
coke. 
New Mexico No. 4 B. — Test 150: Light-gray color; silvery deposit of carbon; metallic 
ring; cell structure good ; breakage somewhat cross fractured, but pieces i >i g< lod, 
large, uniform size; good, heavy coke; high ash. 
Test 151: Light-gray and silvery color; large deposit of carbon; metallic ring; 
cell structure good; breakage good; long, large pieces; good, strong, heavy coke; 
ash reduced by washing. 
New Mexico No. 5.— Test 146: Light-gray color; cell structure a little large; breakage 
somewhat marred by cross fracture; good, heavy coke; ash high; blaze Lost
