Remarks : , 



During the winter of 1868-9, the work was prosecuted with considerable 

 interest and diligence, but like all other matters not directly personal, it 

 soon began to be neglected by the committeemen who were all deeply en- 

 gaged in their own aftairs, and Mr. Nettleton was left to work out the 

 problem as best he could, almost alone. 



Meantime the field widened. New developments at Scrubgrass and 

 Parker's Landing led off to the south, far beyond the limits proposed for 

 our work. Mr. Nettleton had been attracted to the west, and connected 

 himself with the Engineering Corps of Greeley Colony, which made it neces- 

 sary for him to close up his affairs in the Oil Regions, preparatory to his 

 removal. No one had any personal interest in continuing the investigation, 

 and the work stopt just when it should have been carried forward, leaving 

 the materials in hand in such an unfinished and incomplete condition that 

 no report could be made which would be at all satisfactory to those who 

 had subscribed to the funds for the Survey. 



This was in the Spring of 1870. Mr. Nettleton before leaving Pleasant- 

 ville, placed all the accumulated papers of the Survey in my hands, where 

 they have remained to the present time. They were accompanied by the 

 following brief report to the Committee, dated Pleasantville, April 1, 1870, 

 and addressed to the Committee of the Topographical Survey : 



Gentlemen : — I herewith present to you the facts and papers relating to 

 the Survey which I commenced over one year since. 



Levels have been carried to nearly all the important producing centres 

 of the upper district, but I have not been able to connect Parker's Landing 

 with the survey in consequence of its distance from my nearest ' ' bench 

 at Venango City. I expected to have obtained the elevations along the 

 Allegheny Valley Railway from its Chief Engineer, but have been disap- 

 pointed. 



Many difficulties have been encountered in getting information from 

 well owners on whom I am entirely dependent for the data so essential to 

 this work. Some are not willing and prompt in assisting in this way be- 

 cause they are under the impression that it is a private enterprise ; but the 

 most serious obstacle met with is the characteristic indifference of the people
