Circular A. Pleasantville Pa 1868. 



Deak Sir: — A pressing need lias long been felt by the more thoughtful 

 operators in the Pennsylvania Oil Regions for a more thorough and accur- 

 ate knowledge of the thickness, dip and general characteristics of the Oil- 

 bearing Rock iu this section. The drillings in dilterent localities have es- 

 tablished data suflicient for operations in those particular places, but no 

 effort has been made to connect these together in one comprehensive whole, 

 and very little is know^n as yet of the relative positions of the Oil-bearing 

 Rocks in these several localities. In order that this want may be supplied 

 a fund has been raised, a committee appointed to supervise the work, and 

 the services of a competent Engineer secured. It is proposed to make an 

 accurate topographical survey of PleasuntviUe, Enterprise, Bean Farm, Pit- 

 hole, Shamburg, Bull Run, and Pioneer Oil Districts, and then by a com- 

 parison of the records of a large number of the most prominent wells in 

 said districts, to prepare and publish a report, \vhicli we think will contain 

 facts and figures of great value to those engaged in the development of Oil 

 Territory. In furtherance of this object the enclosed series of questions 

 have been prepared which we hope you will be so kind as to fill out and 

 return to us, — and any further information you may be able to give will be 

 duly acknowledged.
