The interval of TO feet between the Rider coal and the Meigs 
Creek coal is mostly occupied by shale and sandy shale. 
Ames limestone .—The Ames limestone is well developed through¬ 
out the greater portion of the township wherever its horizon comes 
to view. Halfway down the slope into Town I ork of \ ellow Creek 
it shows as a solid bed 2 feet or more in thickness. Hast and south¬ 
east of Knoxville it is found in the streams and can easily be followed 
for 2 miles or more to the east. In this direction it. rises rapidly, 
but before reaching the summit of the hills it appears to have been 
cut out or replaced by a heavy brown sandstone. Near the summit 
of Myers Knob, back of Toronto, is a disintegrated limestone which 
is believed to be the Ames, but it could not be positively identified. 
On Hale Run south of Knoxville the point of outcrop of the Ames 
limestone is near the township line. Here it is a solid bed about 1 
foot thick. The elevation of the Ames limestone and the Pittsburg 
coal were compared in the following places for determining the inter¬ 
val between them:

The interval between the Pittsburg coal and the Ames limestone is 
occupied principally by shale and sandstone, except for a small lime¬ 
stone adjacent to the coal. The normal position of the sandstone is 
about 20 feet above the Ames limestone, but in many places it dis¬ 
places the limestone. The shale when adjacent to the limestone is 
of a red color. The coals usually accompanying the Ames limestone 
were not found in Knox Township. 
Finley coal .—The Finley coal, which is probably equivalent to the 
Upper Freeport of Pennsylvania, shows in outcrop in the north fork 
of Croxton Run and in the river hills back of Toronto and Free¬ 
mans. The thickness of the coal is less than 3 feet, and although 
opened in a few places it has not been successfully mined. 
Royer coal .—The Roger coal is opened for mining on Croxton Run 
a mile and a half from Ohio River. From this point it may be fol-
