outcrop brings it beneath Sodus bay. In the same way Hall identi- 

 fied the ore bed at Wolcott furnace with the seam opened to the 

 east and recently worked at Sterling- Station, while they are really 

 two different beds separated by from 75 to 100 feet of shale. 



Clyde, Wayne co. A deep well was put down in 1887, in the 

 village of Clyde, about 13 miles south of the Clinton outcrop. The 

 altitude at the mouth of the well is given by Prosser,^ from whose 

 paper the record has been taken, as 389 feet. The boring was made 

 with a churn drill. The iron ore reported is near the top of the 

 Clinton and represents probably the upper ore horizon.

Red marls (Salina) , 156

The well was continued into the Hudson River beds, reaching a 

 total depth of 1792 feet. 



Allowaj;, Wayne co. In 1899 a deep boring was made at 

 AUoway, 18 miles south of the Clinton outcrop and 8 miles south- 

 west of the Clyde well at an altitude of 410 feet.^ The well was 

 started in the Salina and the Niagaran group was reached at 580 

 feet. No data were obtainable as to the Clinton beds, but they must 

 have been penetrated above 980 feet where the first Medina was 

 found. 



Seneca "Falls, Caynga co. A deep well was put down at this 

 place, which is 12 miles southeast of Clyde and 25 miles south of 

 the Clinton outcrop near Wolcott.^ After penetrating the Salina 

 formation, the Niagaran strata were encountered at 950 feet. The 

 combined thickness of the Clinton, Rochester and Lockport beds, 

 which are not differentiated in the records, is given as 400 feet. 

 The top of the Medina was encountered at 1350 feet. The altitude 



of the mouth of the well is 385 feet.
