Not illustrated. 1914 edition. Excerpt: ...three miles west of Nebo, it is 209 feet and 6 inches. The Nebo coal is correlated with the coal found over a considerable area in Webster County, in the region of Clay, Wheatcroft and Hearin and now mined at Baker. This correlation was first suggested by Glenn in Bulletin No. 17, Kentucky Geological Survey, 1912. His correlations were based on its position with reference to No. 9 coal. Since there is considerable irregularity in the interval between No. 9 coal and the Nebo coal due to unconformities the writer has endeavored to make the correlation with reference to the Madisonville limestone. Recent investigations in Henderson County indicate that the Smith Mills and Corydon coals can be correlated with the Nebo coal. In nine core hole records in the region of Wheatcroft, llearin and Clay, Webster County, the interval between the lower member of the Madisonville limestone and the Nebo or Baker coal varies from 153 to 169 feet, with a general average of 162 feet. This shows a thinning of the interval between the coal and the Madisonville limestone to what it is in Hopkins County. In the same region of Webster County the interval between No. 9 coal and the Madisonville limestone averages 285 feet. At the Rose Creek Coal Company's shaft at Coiltown the interval between No. 9 and the Nebo coal is about 294 feet. If we add to this 185 feet, the distance from the Nebo coal up to the Madisonville limestone, the interval between No. 9 coal and the Madisonville limestone at Coiltown would be 479 feet. There seems to be some inconsistency in the core records at Coiltown and Circle City, since the core record No. 27 on the Owen Helm farm, near Nebo, gives an interval between No. 9 and the Madisonville limestone as 311 feet.
