The (Mean Conglomerate is probably represented in the record by the 

 sand from30to85 feet below the top of the well. 



The records of the Bear Creek and Silver Creek Wells are invaluable as 

 having a direct bearing upon the probable existence of petroleum to the 



south and south east of Wilcox. 



It will be noticed that the mass of the red cocks an- some !$00 feet lower 

 in the the Hear and Silver Creek Wells than in the Wilcox Wells, estimat- 

 ing from the bottom of the Olean Conglomerate. 



The question as to whether the mass of red hands in the two localities 

 ai'e tin' same and whether the strata included between them and the Olean 

 have thickened to the south and south-east, is extremely suggestive. 



Note. — The records are published just as they have been reported to 

 me. I have not even altered the phraseology, which is quite different in a 

 number of places where the same idea was evidently intended to be con- 

 veyed. 



1 will merely add, for those who are unacquainted with the terms em- 

 ployed by the drillers, that "shell" means any hard stratum encountered 

 in the well, and not, as might be supposed, a fossil.

Mi Dear Silt: — I have read the address you sent me on Sylviculture 



with greal interest, especially as some of its facts have come under my own 



observation. The western part of Pennsylvania was once anion- the besl 



I portions of it, vet the destruction of timber has plainly affected
