A NEW TREE FROM THE CARBONIFEROUS ROCKS 
OF MONROE COUNTY, OHIO. 
By H Herzer, Berea, O. 
Plate VI. 
In the higher Carboniferous rocks of Ohio a peculiar species of 
tree has been found, especially stumps of that species of con- 
siderable size, varying from one to two feet and more in diameter 
and from three to four feet at base, with a hight from two to 
three feet, and showing no characteristic mark to determine its 
species. It is nothing but an arenaceous mass with somewhat 
longitudinally fluted surface, betraying vegetable character. Two 
or three such stumps are in the college collection at Marietta, 
0. Two years ago I found one in a sandstone quarry 400 feet 
above the Ohio river, at Baresville, Monroe Co., 0., in upright 
position, from where I had it removed to the campus of the Ger- 
man Wallace college, Berea, 0. 
It seemed remarkable to me that not a single trace of silicifi- 
cation could be observed to show any structure whatever. Be- 
ing on a constant lookout for some silicified mass which I thought 
must occur in sandstone, I was overjoyed last summer in finding 
in the bed of a run, among worn lime and sandrocks, a partly 
worn but silicified stump of a tree, being in form and external 
markings the same as those found heretofore of purely arenaceous 
mass. I was surprised at the good preservation of its structure,
