MINUTES OF MEETINGS. 113 



Such is a representation, generally, of the lower portion 

 of the Allegliany Coal Field in its Northern half. The 

 depths to which shafts must be sunk any where in Ohio to 

 cut all the beds, is not great — by no means equal to the 

 depth of coal mines in Great Britain. 



In the district of Tyne and Ware, South Staffordshire, the 

 deepest pit is five hundred and ninety-eight yards, or seven- 

 teen hundred and ninety four feet. 



At the mouth of Yellow Creek a shaft less than one thou- 

 sand feet would pass all the subordinate beds that crop out 

 in Ohio. 



The English Coal Fields, in different parts, present the 

 same irregularity in the thickness and in the number of 

 beds as our own. 



A section of the Manchester Coal Basin in one part shows 

 eighty-five (85) seams more than a foot in thickness — in 

 another only thirty-six (36.) 



The entire thickness of the Alleghany Coal Series is not 

 yet well determined, nor the entire number of beds- It is 

 to be hoped that the Legislatures of the four States that 

 possess such vast riches in coal, as Ohio, Kentucky, Virginia 

 and Pennsylvania, will eventually feel the necessity of 

 having more detailed examinations made in concert through- 

 out this field.[j 



The proceedings of the Academy, from this time until 

 1859 or 1860, were published in the Ohio Farmer^ Messrs. 

 Thomas Brown, John Kirkpatrick and John H. Klippart, 

 all active members of the Academy at that time, being 

 connected with that paper. It is from the files of the Ohio 

 Farmer^ kindly furnished for the purpose, by the present 

 owner, that most of the following proceedings and papers 

 which were read before the Academy have been copied.
