Mr. Jacob Aman’s quarry (about N. W.4 section 18). It occurs along a 
little ravine running north, and shows the following section : 
SECTION AT JACOB AMAN’S QUARRY. 
No. 1. Rusty, irregular, shattered sandstone; micaceous, with in- 
tercalated beds of shale; beds 1 to 6 inches............... 0.00 7 feet. 
‘‘ 2. Micaceous shale with intercalated beds of sandstone (some 
of which are fossiliferous). This shale is argillaceous, and 
when dried has a glittering and soapy luster, appearing

Jacob Mandeville’s quarry is situated N. HE. 4 section 13, in North 
Bloomfield, and consists, so far as exposed, of a hard, ringing, blue lime- 
stone, which seems silicious. The most of a thickness of eighteen inches 
is devoted to this limestone. Generally a coating of sandstone incloses 
the limestone, filling out the angles in the bedding, and making the 
limestone really he in lenticular pieces, with rounded edges. Beds of 
sandstone are known to underlie this limestone, but the overlying rock 
is unknown. No fossils have been seen. The beds are horizontal. 
The quarry of Mrs. Elizabeth Treisch is on the N. W. 4 section 19, 
Troy, and occupies the banks of a precipitous ravine. The section ex- 
posed is as follows, in horizontal beds:

Daniel Stull owns a quarry in the same beds, adjoining Mrs. Treisch’s. 
Along the creek, in section 36, North Bloomfield, Mr. John Snyder and 
Mr. Daniel Sorrick have taken out a little stone for common use. It les 
in thin beds, and is poorly exposed. 
On lot 8, William Struble’s land, a mile and a half north-east of Ches- 
terville, about ten feet of sandstone beds are exposed in the banks of a 
ravine. These beds are similar to those of widow Treisch’s quarry, sec- 
tion 10, Troy, and are rarely over three inches in thickness; one layer is 
fourteen inches in thickness. 
On the N. W. 4 section 5 (east), Franklin township, Mr. Milton Laver- 
ing has a quarry in the bluffs of a ravine, which expose about thirty 
feet of alternating sandstone and shale layers. The sandstone is soft,
