676 ' GEOLOGY OF OHIO. 



But a single economical application is made of the Cedarville lime- 

 stone. The facts already stated show how poorly adapted it is for use as 

 a building stone, but as a source of quick -lime this stratum is without a 

 rival in the markets of south-western Ohio. This subject has already 

 been discussed at considerable length in the report on Clarke county. It 

 was there shown that the Cedarville stone is to be equally commended for 

 this use by the economy with which it can be manufactured, and by the 

 great excellence in every respect of the product which it furnishes. 



Lime is now burned in quantity at but two points in Greene county, 

 viz., Yellow Springs and Cedarville; but equal advantages in every par- 

 ticular, except the all-important one of transportation, are furnished at 

 many other points, and especially at and below Clifton, on the Little 

 Miami Kiver. The business at the two points named has attained quite 

 important proportions, and is the source of a considerable income to the 

 county. A few of the details are here appended. 



At Cedarville lime is now burned by the five following firms : Wesley 

 Iliff, Satterfield and Son, Shrads and Gibney, Orr and Son, D. S. Ervin. 

 These parties are named according to the order in which they took up 

 the business. Wesley Iliff has been engaged in burning lime at this 

 point for thirty years. All of the firms but one use old-fashioned kilns, 

 viz., those in which fifteen hundred to two thousand bushels of lime are 

 burned at one time, the kiln being allowed to cool before it is emptied 

 and re-filled. To carry on the business in a large way, each firm requires 

 two or more such kilns, so that while one is burning lime can be drawn 

 from another. 



Mr. D. S. Ervin alone employs patent draw-kilns. The comparison of 

 the two modes of burning was made at length in the report on Clarke 

 county. (Geology of Ohio, Vol. I., p. 475.) No reason is seen for modify- 

 ing the opinions there expressed. 



The production for the year 1874 ranges as follows : D. S. Ervin, two 

 hundred and eighty car loads, or eighty-five thousand bushels ; Wesley 

 Iliff, one hundred and thirty car loads, or forty thousand bushels ; Shrads 

 and Gibney, one hundred and thirty car loads, or forty thousand bushels ; 

 Orr and Son, seventy-five car loads, or twenty -three thousand bushels ; 

 Satterfield and Son, forty car loads, or twelve thousand bushels. 



The average cost of wood is three dollars per cord, and one cord is used 

 in the burning of fifty bushels of lime in the old pattern of kilns. In 

 the patent kilns, Mr. Ervin reports sixty-six bushels to one cord of wood. 

 The lime finds market mainly along the line of the Little Miami Railroad. 

 The price for 1874 has been fifty-five dollars per car load, or eighteen and
