In these newest coals, a maximumsulfur 3ield of and per cent, has been found in the Dunkard Seriescoal beds of Wood and Ohio Counties along the extreme western boundaryof the state. Then, since the lowest and oldest of the Pennsylvanianbeds crop out farthest to the east along the Virginia border and succes-sively higher and higher groups make their appearance westward, itfollows that there is an increasing amount of sulfur in the West Vu-ginia SJ 00 6S30 S2 00 8130 8100 toSO SO 00 ;0 80 7»00 ;i:30 >00 77 30. a 30 ssoo eoao 3000 to 30 79oo- rsao Fig. 2. coals in going from the east to the west. This law holds good not onlyfor the groups and series, but also for the individual beds where such canbe traced over a wide area, like the celebrated Pittsburgh coal. Forinstance, this coal in Mineral County at the extreme eastern boundary ofthe Pennsylvanian, contains only 1 to 13^^ per cent, of sulfur, and inMaryland often less than 1 per cent., but farther westward this increasesto an average of in Marion and Monongalia Counties, to 4 per cent,in Marshall and Ohio, and still farther westward, on Captina Creek inthe State of Ohio, it is reported to contain over 5 per cent, of sulfur. 934 GEOGRAPHIC DISTRIBUTION OF SULFUR IN WEST VIRGINIA COAL Mr. R.
