A Recorp oF FouRTEEN Orn WELLS AT Brapy’s BEND, ARMSTRONG 
County, PENNSYLVANIA. 
By. J. P., meumy. 
(Read before the American Philosophical Society, Phila., Nov, 1st, 1872.) 
Having recently requested Mr. Persifor Frazer, Assistant Professor of 
Chemistry in the University of Pennsylvania, to examine for new esti- 
mates of quantity the coal areas which have escaped erosion, in the 
country on the two sides of and closely adjoining the Allegheny River, 
at the remarkable ox-bow bend in its course, 70 miles above Pittsburgh 
and 60 miles below Oil City ; he brought back with him a MSS. report of 
ot the wells bored by the company on the river banks and along the beds 
ot the ravines descending to it from the west. We owe this report to the 
kindness of Stephen Halbrook, Esq., Superintendent of the Brady’s Bend 
Tron Works. 
It is needless to recapitulate the history of the oil discoveries, and the 
gradual extension of the oil producing districts from Titusville and the 
line of Oil Creek eastward to the Tidioute district, southeastward to the 
Clarion, westward to French Creek, and southward via Oil City, Franklin, 
Parker’s Landing, and Brady’s Bend, to the neighborhood of Butler, 
where the last discovery excitement is now raging. ‘It is only necessary 
to refer to my report on the geological grounds for believing the middle 
Allegheny River districts to be productive oil country, published in the 
Proceedings of this Society, in 1865.* In that paper I have sufficiently 
described the locale of the wells now to be described. These records may 
also be compared with similar records communicated to the Society and 
published in its Proceedings of April, 1865. 
The ‘‘ Engineers’ Datum’’ of the following table is an assumed level, 
one hundred feet lower than a mark made on the Brady’s Bend Iron Com- 
pany’s warehouse, on the river bank, showing the extreme height réached 
by the great and disastrous freshet of March 17, 1865.
