The New River Group of coals comes next above the Pocahontasbeds; unlike the latter it stretches entirely across the state from northeastto southwest, and, as may be seen from Fig. 3, everywhere averages below1 per cent, in sulfur except in Wyoming County, where the average ()rises slightlv above that figure.

A representative of the New River Groupexists in Tucker County, but since no analyses are available from thisNew River coal in that county the latter is unrepresented on the map. The Kanawha Group of coals appears to represent mainly the Mercer,Quakertown, and Sharon Coals of western Pennsylvania, but they arethin and of piactically very little commercial value in the northern halfof West Virginia. They do not attain much value beyond the meridianof Nicholas County and, while still low in sulfur, reveal an increase over 936 GEOGRAPHIC DISTRIBUTION OF SULFUR IN WEST VIRGINIA COAL Table l.—Aoerage PertmtOQe of Sulphur in 72 Wttl Vtr^inia CoaU fcy flgJ* Seriet aitrf ?
