270 GEOLOGY OF OHIO. 



Cardington Mr. Abram Hickson makes brick and tile, and on section 7, 

 Troy, Mr. W. T. Appleman makes enough to supply the demand in a 

 limited neighborhood. 



Salt— A.t West Liberty Mr. James Flemming owns land on which, in 

 the year 1818, a well was sunk to the depth of about 330 feet. From the 

 brine obtained a few bushels of salt were manufactured. Mr. Barton 

 Whipple, of West Liberty, the only man who could be found cognizant 

 of the facts, reports, by letter, that there were no indications of salt or 

 any salt-lick within forty rods of the well. The well was drilled by A. 

 Walker, but the water did not rise to the top. By means of a thin cop- 

 per tube, 75 feet in length, and a pump, they succeeded in raising enough 

 to make about fifteen bushels of salt. The tube then "collapsed," and 

 no further efforts were made to extract the brine. Four years ago another 

 drill was made at the same place for the purpose of reaching oil, and Mr. 

 Whipple says the same deposit of brine was struck at about 330 feet. It 

 is the impression of some that the location of the well at West Liberty 

 was determined by the occurrence of "deer-licks" in that neighborhood. 



A well was drilled a few years ago west of Iberia, near the county line, 

 for the purpose of finding oil. It passed through shale and slate so 

 far as it was prosecuted, which was to the depth of 200 feet. This shows 

 the strike of the Berea grit to be at some point further east, and the ex- 

 posure of the same in Tully township, Marion county, a few miles west 

 of this well, must be an outlying mass. 



For mineral paint the shale lying below the Berea grit seems to be 

 adapted. It has been used to good advantage by Mr. Brown at Iberia. 

 It is dried, ground, and mixed with boiled linseed oil, making a blue 

 paint. It is also worthy of being tested as a fire-clay and for pottery. 



Several deposits of bog ore were met with in the survey of the county. 

 It occurs on land of Samuel Elder, S. E. \ section 24, Washington, and on 

 that of James Thomas, in the same section. The hydrated peroxide 

 which constitutes the ore in most bog deposits here seems to be associated 

 with a considerable spathic iron ore, or carbonate of iron. At Mt. Gilead 

 there is a copious deposit of carbonate of iron on the rock bluffs of the 

 creek, associated with calcite. Other deposits of bog ore were seen in 

 the eastern part of the county. One is in section 5, Franklin township, 

 land of Calvin Blair and of John Blair. A small deposit of crag, or ce- 

 mented gravel, may be seen on Milton Lavering's land, in the left bank 

 of the North Fork of Owl Creek, section 5, Franklin. It is due to the dis- 

 charge of calcareous water from the bank, the source of which it is not 

 easy to explain. 



The economical value of the black slate consists in the supplies of oil
