WELL LOGS USED FOR BURGETTSTOWN CONVERGENCE SHEET. 139 
II ell A o. 702 .— I his well is No. 1 on the Ivrackemer farm, and the 
mouth is at an elevation of 1,135 feet above sea level. The position 
of the Pittsburg coal as given by the well record is accepted. The 
measurement to the Hundred-foot sand is not accepted, however. 
Other wells on the same farm show that the distance between the 
Hundred-foot and Gordon sands is 211 feet, which is verv close to the 
average distance between these sands. It is believed a better result is 
obtained by taking the measurement to the Gordon sand and subtract¬ 
ing 210 feet.

Total depth. 
The depth to the Gordon sand, 2,278 feet less 210 feet, gives 2,068 
feet as the assumed depth of the Hundred-foot sand. The distance 
between this sand and the Pittsburg coal at this point is therefore 
2,068 feet less 270 feet (the depth of the base of the Pittsburg coal, 
265 feet plus 5 feet), or 1,798 feet. 
Well No. 6Jf9 .—This well is on the farm of J. R. and Joseph Lyle. 
Its mouth is at an elevation of 1,161 feet. The depth to the Pittsburg 
coal as given in the record is accepted. It will be noticed that the 
distance between the Hundred-foot and Gordon sands is 320 feet.
