WEST VIRGINIA GEOLOGICAL SURVEY. 593 



The above table represents the amount of coal believed to 

 be available in the two counties. Mining has been conducted 

 en such a small scale that the amount already recovered is a 

 negligible quantity when compared to the total amount. Al- 

 lowing for a recovery of 80 per cent., the total coal that may 

 eventually be mined is, in round numbers, 3,020,000,000 short 

 tons. 



MINABLE COALS BY MAGISTERIAL DISTRICTS. 



The minable coals of the two counties have been described 

 by magisterial districts on previous pages of this Chapter. In 

 the Index, at the end of this Report, under the heading "Mina- 

 ble Coals by Magisterial Districts," will be found a list of page 

 references making this information readily available without 

 further discussion. 



TABLE OF COAL ANALYSES. 



The following table, containing the chemical analysis, 

 calorific determination, and fuel ratio of 58 mines and pros- 

 pects, is the exclusive work of members of the Survey Staff. 

 All samples were taken by members of the force in the field. 

 Those from the commercial mines were taken according to the 

 strict method outlined by the U. S. Bureau of Mines, being 

 quartered and sealed in tins in the mines. The samples from 

 the country mines were collected in sacks with as much care 

 as could be used when depending on a scanty saddle-bag equip- 

 ment. 



The chemical work was mostly done by J. B. Krak, Assis- 

 tant Chemist, under the direction and with the assistance of 

 B. H. Kite, Chief Chemist. The numbers in the left-hand 

 margin correspond to the numbers given with the mine sec- 

 tions in the text and with the mine symbols on Map II. All 

 samples were cut from the mining section of the seam :
