DEFIANCE COUNTY. 427 



No. 1. Very hard, fine-grained, dark-blue or bluish-gray limestone, in 



one layer, containing iron pyrites ; no fossils visible 1 ft. 



[This is the equivalent of the limestone quarried below the mill- 

 dam near Waldo, in Marion county, and a few miles further 

 south, by Mr. Brandage, in Delaware county. It there under- 

 lies immediately the Olentangy shale.] 



" 2. More vesicular, less silicious, bluish-gray, in one bed of three feet 

 thick, showing some crinoidal joints, its upper surface having 

 vermicular markings and fucoidal impressions 3 " 



" 3. The same as No. 2, but in thinner beds ; seen, about 1 "

There is a slight dip to the north. Near here Andrew Dilz burns lime 

 from these beds, the lime being of a bluish-ashen color, and having a 

 noticeable hydraulic quality. No. 3 has considerable thickness, and 

 graduates below into the Hamilton. Another quarry in this stone is 

 mentioned under Geology of Henry County. That of Wm. Wileman is 

 in the same beds, situated in the Maumee River, near the Henry county 

 line. 



The Hamilton. — In the N. E. | section 17, Defiance, on the land of 

 Michael Humbert, is a quarry in the Auglaize River, in a crystalline, 

 vesicular, bluish-gray limestone, that contains considerable chert be- 

 tween the bedding. It holds indistinct cyathophylloid corals. Also, in 

 the chert may be seen the cells of a coarse Pavosites. One bed is about 

 a foot thick. About three feet can be made out. This stone is probably 

 the downward continuation of No. 3 of the last Section, although there 

 is an unexposed distance of about two miles between them. How much 

 of this belongs to the Hamilton, or whether anything below No. 1 of the 

 last section should be included with the Tully, it is not possible to say. 

 It is true, however, that No. 1 of the last section above is the only part 

 that resembles strongly the beds referred to the same horizon seen in 

 Marion and Delaware counties. 



On section 17, Defiance, is the quarry of Town Newton. Stone is taken 

 out there for the Paulding Furnace. The color, grain, and all the exter- 

 nal characters of this stone resemble those of the stone quarried at San- 

 dusky and used in the basement of the court-house at Defiance. The 

 dip is north or north-east. Further south in Paulding county are other 

 exposures of the same stone, likewise situated in the valley of the Au- 

 glaize. The reader may consult the report on that county for remarks 

 on the supposed equivalents of these limestones in New York. 



On section 24, Delaware, Elias Bruner has discovered a stone in the 

 bottoms of the Maumee which belongs to the Corniferous limestone, i. e., 

 to the fossiliferous, light-colored beds that first underlie the blue lime-
