 A HICH-GRADE BUILDING STONE IN GREENE COUNTY. 
 By 
 
 George H. Ashley 
 
 
 
 Recent studies by the State Geological Survey reveal the fact 
 that hidden away in Greene County is what may prove to be one of the 
 finest general building stones in the State. 
 
 The most popular building stone in the United States today is the 
 limestone from Bedford, Indiana and Bowling pvsonh Kentucky. ‘This 
 Stone is light gray and even grained, differing from most limestones 
 
 in having a grain like sandstone. . It is massive, so that blocks of 
 
 o 
 
 . te lle 
 
 any dimension can be cuarried, and is soft enough to be worked readily, 
 but it hardens on exposure. It can be carved into statuary or orna- re 
 mental trimmings and keeps its color. Because of these qualities the 
 Bedfora Stone is usec from one end of the country to the other. 
 Phe stone in Greene County so closely resenbles the Bedford stone 
 a) that average person Hote not tell them avart. The Greene County 
 product however is a sandstone and therefore has en advantage in thet . 
 it is not affected in the same way aS limestone. It is the same even 
 
 light eray as the Bedford stone, and buildings in Waynesburg erected ..

15 or 20 years ago showing neither iron streaks or other stains indi- 
 cate that in a rural district the color remains as clear as in the 
 freshly quarried stone. 
 
 The Greene County stone is massive bedded and remarkably even- 
 prained both with and across the bedding. Blocks can be gotten out as 
 large eS can be handled. The stone is soft and easily worked when 
 freshly quarried but the surface hardens with time. Tool marks on the 
 Stone in buildings 15 or 20 years old still show as sharp as when cut, 
 The stone neither spalls nor weathers and can be cut into statuary or 
 ornamental pieces, as shown by the Soldiers and Sailors monument at 
 Waynesburg. 
 
 Indeed, the Greene County stone seems to be ideal for office 
 buildings, residences and monuments. It has however at present, two 
 hancicayvs, So far as yet tracec, it lies in the hill in such a way as 
 to require underground mining or very heavy stripping. In the second 
 place. Waynesburg, near which the stone has been quarried, is connected 
 with the outside world only by a narrow gauge railroad, 
 
 These facts were brought out in a recent preliminary study of the 
 stone by J. French Robinson, Geologist of the State Survey in the 
 Devartinent of Interme1l Affairs, The Survey plens to extend its study 
 to determine whether the stone occurs only in a pocket or whether 
 stone of Similar character is widespread. If the latter proves to be 
 the face, doubtless places will be found where the stone can be 
 
 quarried cheaper.
