Martville, Cayuga co. The site of this drill hole is on the 

 west bank of Sterling creek about 15 rods below the bridge at 

 Martville, on the property of Dr John Chapman. The locality is 3 

 miles southeast of Sterling Station and 5 miles northeast of Red 

 Creek.

With the exception of a few 

 feet at base, this shale is purple 

 in color. It includes a number of 

 pearly limestone bands, between 

 33 and 57 feet. A few other light 

 crystalline limestone bands occur 

 at 45 and 54 feet. In thickness 

 the bands of limestone vary from 

 a fraction of an inch up to 6 

 inches. 



One inch of lean ore is followed 

 by I foot of shale and limestone. 

 Another inch of lean ore at 84' 5", 

 followed below by dark shale with 

 limestone bands. 



Fossiliferous limestone with 

 bands of shale. Below this lime- 

 stone is the horizon for the main 

 ore bed as encountered in the 

 drillings farther west. 



Upper few inches brecciated, 

 followed below by greenish shale 

 and sandstone. Below this is a 

 very hard white sandstone, fol- 

 lowed by a foot of mottled sand- 

 stone. Medina horizon. 



This section seems to establish that the ore body which stretches 

 across Wayne county and as far east as Sterling Station, Cayuga 

 CO., terminates practically near the latter locality. The excavations 

 made by the Fair Haven Iron Co., at Sterling Station, give some in- 

 dications of a wedging out of the ore toward the cast, though from 

 the evidence here it docs not follow that this is anything more than 

 a local condition. The ore bodies are everywhere subject to moder- 

 ate variations in thickness, but the pinches are usually succeeded 

 in turn by bulges that maintain the average. There is no otlicr
