1891.] AO [Lesley. 



I could get no clear idea of this from Mr. Rosenzi's description. He 

 first noticed the salt as a deposit from water splashed on the derrick. 

 The salt taste was decided. He could say nothing about the flow, as the 

 well was always full of water, but I could not learn that any stream 

 issued from the mouth of the well.

"The driller remarks that here came in genuine soft black slate, which 

 he recognized as the overlayer of the Oil Sand in Allegheny county, in 

 the Wild Wood district where he worked." Nothing could more forcibly 

 illustrate the ignorance of the well drillers as a class than this astounding 

 statement ; which is only exceeded by the ignorance of oil and gas specu- 

 lators as a class, and the stockholders of the companies which they form, 

 in giving ready credence to such statements from men whose only inter- 

 est is that of obtaioing their daily pay for boring wells.
