silica. But the ore from this bed at the tunnel mentioned 

 above, not yet analysed, may yield a different result. It 

 contains a larger quantity of carbonate of lime than I have 

 seen in this bed elsewhere in the county ; so much, indeed, 

 that in many cases the fossils remain ; whereas, they are 

 usually re})resented by casts. 



Beside the ore bed above described a second exists lower 

 down and separated from the one above it by about thirty 

 feet of rock. It is not now exposed anywhere and can- 

 not therefore be examined. But in all probability this sec- 

 ond and lower bed is really the bed which is usually worked 

 in the county. This is the case along the next exposure to 

 the northward — the south side of Dick's hill — where three 

 beds exist, the uppermost being the Fenestella shale which 

 at that place becomes ferriferous. This view is supported 

 by the fossils, which agree with those of the second bed at 

 Dick's hill but not with those of the Hamilton fossil ore 

 bed usually mined. 



The Genessee, Portage, Chemung, {VIII.) 



I have not been able to completely trace the lines of these 

 groups in Rye township. The whole mass is very thin, as 

 exposed in many places along the north slope of Little 

 mountain. Above Newport these rocks are 3800 feet thick ; 

 but here in Fishing creek they are all included in a space 

 of about 1100 feet, showing a remarkable thinning down 

 southeastward. Like all the other rocks in the Blue and 

 Little mountains these beds are vertical or slightly over- 

 thrown and stand on edge with a dip of 9o°— 100° IS". 30° 

 W. They are not exposed along the railway, their edges 

 being covered with washed material from above. 



These rocks present no unusual features in this township 

 but it is worthy of notice that so far as can be determined by 

 a superficial examination the hard, sandy Upper Chemung 

 beds of Newport are not present, or if present are not hard, 

 so that no bold ridge is formed along the valley by their 

 outcrop.
