West Virginia No. 12. — Run-of-mine coal from mine of the Big 
Sandy Coal and Coke Company, Big- Sandy, W. Va. 
Two coking tests were made of this coal, one of raw coal and one of 
washed coal. The first charge consisted of about 5J tons of coal and 
the second charge of about 4i tons. No particular change was noted 
in the coke made from the two grades of coal, but the analyses show 
a reduction of ash as follows:
