PAULDING COUNTY. 343 



No. 1 of this section does not appear in Paulding county, except in 

 the form of floating pieces transported with the Drift. . It is fully de- 

 scribed in reports on other counties. 



No. 2 appears in the Tiffin River, at Brunersburg, where it embraces 

 a shaly limestone which crumbles under the weather. Such limestone 

 is in detached lumps and lenticular masses. It is washed out of the 

 shale near Waldo, in Marion county, by the force of the water of the 

 Olentangy, where it falls over a dam. It is entirely unfossiliferous, as 

 well as the shale in which it lies. In north-western Ohio No. 2 is very 

 much reduced from its observed thickness in Delaware county (30 feet), 

 and is usually altogether wanting. It is evenly but very thin-bedded, . 

 and is closely related to the Huron shale (No. 1), with which it is inter- 

 stratified in Delaware county. 



No. 3. This holds the place and exhibits most of the characters of 

 the Tully limestone of New York. Its identity is not established on 

 palseontological evidence. It is quarried at Florida, on the Maumee, 

 and by Mr. Dilz, near Defiance. At the former place it is immediately 

 overlain by the black slate. Its thickness is six to ten feet. 



No. 4 has a thickness in Delaware county of 35 feet, and probably it 

 will not vary very much from that on the west side of the anticlinal. 

 There are no exposures in these counties favorable for learning its aggre- 

 gate thickness. In the season of 1871 a collection of fossils, character- 

 istic of the Hamilton, was made in the N. E. J section 30, Auglaize, in 

 Paulding county. The species here gathered were those already enume- 

 rated in the description of the outcrop at that place. Time was not 

 sufficient then for determining certainly the relation of this stone to 

 the rest of the blue limestone. In the season of 1872 this point was 

 made the subject of careful investigation. The result arrived at was 

 the conclusion that the beds that hold these Hamilton fossils are very 

 near the bottom of the blue limestone. The evidence is not that of 

 actual, observed superposition, but that which is based on a series of 

 observations along the Auglaize valley on the dip of the underlying- 

 rocks. It is a very observable fact that the limestones of north-western 

 Ohio are very evenly and regularly laid down, and have not been dis- 

 turbed by any force so as to introduce exceptional, or even extraordinary, 

 dip in any direction or degree. In passing along the valley of any of 

 the streams that expose the rock, this fact is very apparent. The 

 formations succeed each other in perfect conformity with the known 

 general dip. It is so in Paulding county. The Waterlime, the lowest 

 in the series of rocks in the county, occupies the most southerly part of 

 the county. Its upper horizon unites with the Oriskany at Charloe.
