Survey. The report which Mr. James T. Hodge and myself made to Mr. 
H. D. Rogers, Chief of the Survey, may be found recorded in the Fifth 
Annual Report (1841), pages 89-92, which I will here recapitulate in the 
descending order of the beds, for convenience of comparison. 
The Pittsburgh bed, I, has been eroded from the whole country between 
the Alleghany Mountain and Chestnut Ridge (at Connellsville and 
Blairsville) except two hill tops; one, near Salisbury, and the other near 
Ligonier. It is possible also that a third exception may be discovered in 
the high hill country south of Johnstown, where a conspicuous bench 
runs along the hilltops for several miles. 
Limestone, 20 feet below I, 6 feet thick in the Ligonier Basin. 
Coal bed H, 50 feet below I, 3 feet thick in the Ligonier Basin ; 1 foot 
thick in the Salisbury Basin. 
Coal bed G, 100 feet below H, 1} feet thick in the Salisbury Basin; en- 
circles the highest hilltops in the Ursina Basin with a conspicyous bench. 
Fort Hill is not quite high enough to have it. 
Red Shales between G and F. 
Coal bed F, 90 feet below G; generally small; but 4 feet thick in the 
Salisbury Basin. It forms the high terrace of the Fort Hill. 
Mahoning Sandrock. 
Coal bed H, <‘ Upper Freeport,’’ 50 feet below F; 2 feet thick, on 2 feet 
of Limestone (over it Shales with ore-bails) in Ursina Basin ; 3 feet thick, 
on 5 feet of Limestone in the Salisbnry Basin. 
Ooal bed D, ‘‘ Lower Freeport,’’ 60 feet below E, 6 feet thick in Ursina 
Basin ; 4 feet, further north; over 10 feet of Sandstone with ove bails, in 
two beds, 7 feet asunder, 11 inches in all. This ore ball horison is very 
extensive north and south of the River. 
Coal bed C, 20 feet below D, 23 to 4 feet thick. 
Coal bed B, 30 feet below C on Cox’s Creek, 40 on Laurel Hill Creek 
(N. Fork), and 60 at Confluence ; 4 feet thick over 8 feet of Limestone on 
the river; 1} feet thick over 4 feet of Limestone on the North Fork. 
Twenty feet above B lie 15 feet of Shales, etc., containing ore balls, on 
Spring Run, below Pinkerton’s Bend of the river. 
Coal bed, 22 feet below Limestone, on west bank of Castleman’s river, 
+ mile above Zook’s run ford, and on North Fork at old salt boring ; 
carries 5 feet of Shale containing 1 foot of ore balls. 
Coal bed A, 70 feet below B; 22 inches thick, at Shroff’s Bridge over 
Castleman’s river. : 
Conglomerate ; 30 feet below A ; the interval being massive Sandstone. 
Such was the general scheme of the Coal measures made out during 
the old survey, and, however subsequently modified, it has been of in- 
calculable value in all subsequent special, and private investigations. 
It was a very successful attempt to reduce to system the heterogeneous 
mass of details collected from all parts of the Bituminous Coal Region 
of western Pennsylvania outside, or to the east, of the Monongahela River 
Upper Coal Beds, and of the Alleghany River Lower Coal Beds. It was
