is 185 feet of a blue gray clay or very fine sand, described to be "without 

 grit." A soft shale was then penetrated to a depth of 13 feet, where water 

 was struck which rises above the surface and forms a strong artesian well. 

 The altitude of the well mouth is about 1,415 feet above tide. 



White reports^ a well 1 mile south of Concord, in Erie County, Pa., 

 which penetrated 119 feet of drift. The altitude of the well mouth is 1,375 

 feet. 



Along Oil Creek, in Crawford County, several deep wells have been 

 sunk which penetrated heavy drift deposits, of which the following is a 

 tabulated statement:

In the well records collected by the writer assorted material constitutes 

 the bulk of the section; in those collected by the geologists of the Pennsyl- 

 vania survey the character of the drift is not reported. 



On the uplands west of Hydetown, at an altitude about 300 feet above 

 the creek, there are wells which have a larger amount of di'ift than is com- 

 mon outside the main valleys. They are on a small tributary of East Sugar 

 Creek. One on F. B. Schreiner's farm penetrated 190 feet, and one on Mr. 

 Totham's farm 178 feet, and a second one on the same farm 60 feet of drift. 

 These were reported by Mr. Aikin, of Hydetown, who assisted in drilling 

 them. Mr. Aikin states that they show a much larger amount of drift than
