A LARGE BOULDER IN SOUTHERN OHIO. 



By S. S. ScoviLLE, M.D., Lebanon, Ohio. 

 About two and a half miles southeast of Lebanon, Warren County, 

 Ohio, may be seen a boulder, which, for size, we venture to say, is the 

 largest found in Ohio so far to the South. Prof. Orton, in his reports^ 

 mentions a large one, but it is much less in size, and further to the 

 North. Our rock is situated in latitude 39° 25' 4", and longitude, 

 saj^ 84° 6'. It seems to be a quartoze granite. In shape, it might 

 be considered an irregular ovoid. Upon quite a careful measurement, 

 we find the dimensions as follows: length, 21 feet; width, 16 feet; 

 height above ground, 8 feet. Indications show that it extends at least 

 4 feet beneath the ground. It would most likely cube 14 feet. Supposing 

 the weight to be 190 lbs. to the square foot, and we would have for the 

 entire weight of this stone, 521,360 lbs., oi- something more than 200 tons. 

 The rock rests upon ground sloping 3 or 4 degrees towards the north. It 

 lies within what may be i-egarded as a belt of boulders, which extends, 

 say 2 miles north and south, and 1 mile in width. Within this belt 

 are found numerous rocks, from 300 to 40,000 lbs. in weight.
