Indian Territory No 3. — Run-of-rnine coal from mine No. 1, D 
Edwards & Sons, Edwards, Ind. T. 
Coking tests were made on this coal in both the raw and the washed 
condition, but the washing does not appear to have been successf J 
in reducing materially either the sulphur or the ash. No coke wa; 
made from either charge. The amount of impurities is shown in thi 
following table:

About 5 tons of this coal were washed for a coking test, but the 
was not tried in a raw condition, and consequently the coking ti . 
affords no clue to the improvement made by washing. The change 
shown by the chemical analyses.
