4. The Ore Band-rock may be traced along its line of out- 

 crop by the color of the stone and the fossils it contains. 

 It is difficult to distinguish it from the Medina sandstone 

 in the Tuscarora range, but in the axis of Conecocheague 

 on the edge of the township signs of its appearance may be 

 seen which become more marked over the line in Madison 

 township. 



5. The Sand-rock ore bed, judging from indications, ex- 

 tends all along its line of outcrop — on the top of the sand- 

 rock. But without railway carriage it is of no value and 

 little has been done towards seeking it. 



The Red, Variegated and Gray shales of the Onondaga 



group ( V. ) 



These shales cover the greater part of Raccoon valley and 

 by their disintegration form the usual fertile soil. They 

 are well exposed in short sections in several places, especi- 

 ally near Buffalo mill, where the following section was ob- 

 tained, chiefly remarkable for the fossil remains which it 

 yielded (See Plate XXXVI, Fig. 2) : 



Solid red shale, (top,) 200'+ 



Greenish yellow shale, 2' 



Red shale and sandstone, with fish scales? 4' 



Red shale and sandstone, 10' 



Red shale and sandstone, with fish scales? V 



Sandy red shale 3' 



Greenish yellow shale, 1' 



Soft red shale, (almost a soft fossil ore,) with Leperditia alia, 3' 

 Red shale, (base,) 100'+ 



The above section was found about half a mile east of the 

 mill. Close by the mill a similar section of apparently the 

 s;it!ic bed, in the same order, is also exposed. This is one 

 of the very few places where the red shale and sandstone 

 have yielded fossils. For an account of these the reader 

 is referred to the volume on palaeontology, and the appen- 

 dix to the present report.
