burg Coal by 75 to 100 feet in the Great Kanawha Valley, and 

 is 150 to 200 feet below the Black Flint, should crop above 

 drainage in southern Lewis. At the mouth of Fallen Timber 

 Run, one-half mile east of Bablin, the blossom of a coal was 

 noted at an elevation of 1040' B., coming 175 feet below the 

 blossom of the Stockton, which represents practically the same 

 level as the Flint, and this lower blossom should be the Wini- 

 frede. At other points it was not observed and it was not 

 noted in well records where its horizon lies underground, so 

 it may be disregarded as an economic deposit. 



THE UPPER CHILTON? OR CLEVELAND SANDSTONE. 



Along the north bank of the Little Kanawha River at 

 Cleveland, a massive gray sandstone cliff occurs, the base of 

 which is concealed below drainage, 45 feet being exposed 

 above water level. The Upper Kittanning Coal is opened in 

 .the hill north of Cleveland, 500 feet above river level, as shown 

 by the Cleveland Section, published in Chapter IV, showing 

 that the stone along the river, allowing for the southeastward 

 rise, must be at least 400 feet below the top of the Pottsville. 

 It is possible that this may represent the Upper Chilton Sand- 

 stone of Hennen and the writer, 9 but there is no certainty that 

 this is the fact. This sandstone makes bluffs down the riv< 

 below Cleveland. Opposite the mouth of Williams Camp 

 Run at Bois, it makes a great cliff, 55 feet of it being visible, 

 with its top at 1135' B. One-half mile west of Bois, it makes 

 a cliff, 30 feet thick, north of the river, illustrated by Plate 

 XXVI, its base being 1065' B. Since there can be no assur- 

 ance that this ledge extends through to the region of the ex- 

 panded Kanawha Group, it will be called the Cleveland Sand- 

 stone until further work has shown its true place in the 

 measures. 



The Cleveland Sandstone is the lowest outcropping for- 

 mation definitely recognized in either Lewis or Gilmer. A fev: 

 feet of the measures are exposed below it along the Right 

 Fork of the Little Kanawha, but their nature was not well ex-
