In arriving at the above averages upon which the boundaries of thethree districts were determined, 514 selected air-dried analyses were usedout of a total of about 750, which were reviewed. These analyses weremade by two agencies, the U. S. Bureau of Mines and the KentuckyState Chemist. The number of analyses used per county may be foundby referring to the map. For example, Floijd, —37A, means thatthe Floyd County percentage of sulfur of was secured as an averagefrom 37 analyses. In the following table of the important low-sulfur coals of easternKentucky access was had to over 250 additional analyses of the samecharacter out of which 160 were selected and used in compilation of the
