would be altogether above the available coals, oscillating between Nos. 
11 and 12. In the ravines, some of which are cut three hundred feet 
below the railroad station at Barnesville, Coals Nos. 8 and 10 are exposed 
and worked. Coal No. 9 is traceable with some difficulty, and varies 
from four to eighteen inches in thickness. | 
Along the railroad Coals Nos. 8 and 10 are extensively worked. The 
former has been opened by Mr. T. C. Parker, near Barnesville, to supply 
his cement works. Here this bed, locally known as the Laurel Vein, 
varies much in quality in different portions of the seam. The upper 
pyrites band is fifteen inches from the top, and is one inch thick. The 
coal from the bottom bench is very good for steam purposes, but is too 
impure to be of any commercial value. Mr. Parker has also opened No. 
10, but the quality of the coal is much inferior to that from No.8. Forty- 
five feet above No. 8 there is a limestone five feet five inches thick, from 
which Parker’s cement is manufactured. An analysis of this is as 
follows:

The firm of Parker & Sons began the manufacture of cement in 1858, 
and found a ready market for their product. At the outbreak of the war 
they shut up their establishment, as public‘works were stopped and the 
demand had ceased. In 1868 the manufacture was resumed. In 1869 
this material was tested by the Atlantic and, Great Western Railway 
Company, in competition with eleven other brands, the result being that 
Parker’s cement was adopted. Hleven thousand barrels were supplied to 
the Baltimore and Ohio Railroad Company during the construction of 
the bridge at Bellair. Other tests made on government works, by re- 
quest of Dr. Newberry, have proved, incontestably, the superior quality 
of this cement. The sandstone overlying this limestone contains some 
feldspathic sand and much mica—so large a proportion that it is believed, 
popularly, to be granite.
