273 
feet in thickness, which, with a foot of soil, had to be stripped. Yhe lime- 
stone appeared to be very hard and semi-crystalline in structure. 
“Another exposure visited was on the land of George Shipman, north- 
east quarter section 15 (7 N., 4 W.), where a quarry has been worked for 
macadam road material. At this point the blue Huron limestone was ex- 
posed to a thickness of fifteen to seventeen feet, with four to seven feet of 
buff Huron sandstone overlying. Sufficient material to cover six miles of 
road had been secured at this quarry, the supply in sight being practically 
inexhaustible. 
“The same stone outcrops at many points along Beech Creek, and espe- 
cially in section 12 (7 N., 4 W.), where it forms part of a great precipice 
or perpendicular bluff, 120 or more feet in height, the upper portion of 
which is a massive bed of Mansfield sandstone.” ; 
This latter is evidently the same exposure as that measured by Cox. 
Shannon, in the report on the iron ores of Greene County’, cites several 
instances of the replacement of limestone by iron as in section 6 below, but 
does ot discuss the stratigraphy. 
From the foregcing it will be seen that very little work has been done 
on the stratigraphy or paleontology of the Chester in this area. 
SECTIONS. 
The following sections were obtained along the right of way of the 
Indianapolis Southern Railway, with the exception of Number IX, which 
was taken at the locality mentioned by Cox and Blatchley on Beech Creek, 
being about three-fourths of a mile south of VIII. The sections are shown 
on the profile.
